It is NOT indicated for minor or chronic painful conditions. Ketorolac tromethamine is a potent NSAID analgesic, and its administration carries many risks. The resulting NSAID-related adverse events can be serious in certain patients for whom ketorolac tromethamine is indicated, especially when the drug is used inappropriately. Increasing the dose of ketorolac tromethamine beyond the label recommendations will not provide better efficacy but will result in increasing the risk of developing serious adverse events. Cardiovascular Thrombotic Events Nonsteroidal anti-inflammatory drugs (NSAIDs) cause an increased risk of serious cardiovascular thrombotic events, including myocardial infarction and stroke, which can be fatal. This risk may occur early in treatment and may increase with duration of use (see Warnings and Precautions ). Ketorolac tromethamine is contraindicated in the setting of coronary artery bypass graft (CABG) surgery (see Contraindications and Warnings ). Gastrointestinal Effects • Ketorolac tromethamine can cause peptic ulcers, gastrointestinal bleeding and/or perforation. Therefore, ketorolac tromethamine is CONTRAINDICATED in patients with active peptic ulcer disease, in patients with recent gastrointestinal bleeding or perforation, and in patients with a history of peptic ulcer disease or gastrointestinal bleeding. Renal Effects • Ketorolac tromethamine is CONTRAINDICATED in patients with advanced renal impairment and in patients at risk for renal failure due to volume depletion (see WARNINGS ). Risk of Bleeding • Ketorolac tromethamine inhibits platelet function and is, therefore, CONTRAINDICATED in patients with suspected or confirmed cerebrovascular bleeding, patients with hemorrhagic diathesis, incomplete hemostasis and those at high risk of bleeding (see WARNINGS and PRECAUTIONS ). • Ketorolac tromethamine is CONTRAINDICATED as prophylactic analgesic before any major surgery and is CONTRAINDICATED intraoperatively when hemostasis is critical because of the increased risk of bleeding. Hypersensitivity • Hypersensitivity reactions, ranging from bronchospasm to anaphylactic shock, have occurred and appropriate counteractive measures must be available when administering the first dose of ketorolac tromethamine injection, USP (see CONTRAINDICATIONS and WARNINGS ). Ketorolac tromethamine is CONTRAINDICATED in patients with previously demonstrated hypersensitivity to ketorolac tromethamine or allergic manifestations to aspirin or other nonsteroidal anti-inflammatory drugs (NSAIDs). Intrathecal or Epidural Administration • Ketorolac tromethamine is CONTRAINDICATED for intrathecal or epidural administration due to its alcohol content. Labor, Delivery and Nursing • The use of ketorolac tromethamine in labor and delivery is CONTRAINDICATED because it may adversely affect fetal circulation and inhibit uterine contractions. • The use of ketorolac tromethamine is CONTRAINDICATED in nursing mothers because of the potential adverse effects of prostaglandin-inhibiting drugs on neonates. Concomitant Use with NSAIDs • Ketorolac tromethamine is CONTRAINDICATED in patients currently receiving ASA or NSAIDs because of the cumulative risk of inducing serious NSAID-related side effects. DOSAGE AND ADMINISTRATION Ketorolac Tromethamine Tablets • Ketorolac tromethamine tablets are indicated only as continuation therapy to ketorolac tromethamine injection, USP, and the combined duration of use of ketorolac tromethamine injection, USP and ketorolac tromethamine tablets are not to exceed 5 (five) days because of the increased risk of serious adverse events. • The recommended total daily dose of ketorolac tromethamine tablets (maximum 40 mg) is significantly lower than for ketorolac tromethamine injection (maximum 120 mg) (see DOSAGE AND ADMINISTRATION ). Special Populations • Dosage should be adjusted for patients 65 years or older, for patients under 50 kg (110 lbs) of body weight (see DOSAGE AND ADMINISTRATION ) and for patients with moderately elevated serum creatinine (see WARNINGS ). Doses of ketorolac tromethamine injection, USP are not to exceed 60 mg (total dose per day) in these patients. Ketorolac tromethamine injection is indicated as a single dose therapy in pediatric patients (see DOSAGE AND ADMINISTRATION ); not to exceed 30 mg for IM administration and 15 mg for IV administration."],"carcinogenesis_and_mutagenesis_and_impairment_of_fertility":["Carcinogenesis, Mutagenesis and Impairment of Fertility An 18 month study in mice with oral doses of ketorolac tromethamine at 2 mg/kg/day (0.9 times the human systemic exposure at the recommended IM or IV dose of 30 mg qid, based on area-under-the-plasma-concentration curve [AUC]), and a 24 month study in rats at 5 mg/kg/day (0.5 times the human AUC) showed no evidence of tumorigenicity. Ketorolac tromethamine was not mutagenic in the Ames test, unscheduled DNA synthesis and repair, and in forward mutation assays. Ketorolac tromethamine did not cause chromosome breakage in the in vivo mouse micronucleus assay. At 1590 µg/mL and at higher concentrations, ketorolac tromethamine increased the incidence of chromosomal aberrations in Chinese hamster ovarian cells. Impairment of fertility did not occur in male or female rats at oral doses of 9 mg/kg (0.9 times the human AUC) and 16 mg/kg (1.6 times the human AUC) of ketorolac tromethamine, respectively. Fetal Toxicity Inform pregnant women to avoid use of ketorolac tromethamine and other NSAIDs startingat 30 weeks gestation because of the risk of the premature closing of the fetal ductus arteriosus. If treatment with ketorolac tromethamine is needed for a pregnant woman between about 20 to 30 weeks gestation, advise her that she may need to be monitored for oligohydramnios, if treatment continues for longer than 48 hours [see WARNING S; Fetal Toxicity, PRECAUTIONS ; Pregnancy]."],"clinical_pharmacology":["CLINICAL PHARMACOLOGY Pharmacodynamics Ketorolac tromethamine is a nonsteroidal anti-inflammatory drug (NSAID) that exhibits analgesic activity in animal models. Ketorolac tromethamine inhibits synthesis of prostaglandins and may be considered a peripherally acting analgesic. The biological activity of ketorolac tromethamine is associated with the S-form. Ketorolac tromethamine possesses no sedative or anxiolytic properties. The peak analgesic effect of ketorolac tromethamine occurred within 2 to 3 hours and is not statistically significantly different over the recommended dosage range of ketorolac tromethamine. The greatest difference between large and small doses of ketorolac tromethamine by either route was in the duration of analgesia. Pharmacokinetics Ketorolac tromethamine is a racemic mixture of [-]S- and [+]R-enantiomeric forms, with the S-form having analgesic activity. Comparison of IV, IM and Oral Pharmacokinetics The pharmacokinetics of ketorolac tromethamine, following IV, IM and oral doses of ketorolac tromethamine, are compared in Table 1 . In adults, the extent of bioavailability following administration of the ORAL and IM forms of ketorolac tromethamine was equal to that following an IV bolus.

This implies that the pharmacokinetics of ketorolac tromethamine in humans, following single or multiple IM, IV or recommended oral doses of ketorolac tromethamine, are linear. At the higher recommended doses, there is a proportional increase in the concentrations of free and bound racemate. Distribution The mean apparent volume (V(beta)) of ketorolac tromethamine following complete distribution was approximately 13 liters. This parameter was determined from single-dose data. The ketorolac tromethamine racemate has been shown to be highly protein bound (99%). Nevertheless, even plasma concentrations as high as 10 µg/mL will only occupy approximately 5% of the albumin binding sites. Thus, the unbound fraction for each enantiomer will be constant over the therapeutic range. A decrease in serum albumin, however, will result in increased free drug concentrations. Ketorolac tromethamine is excreted in human milk (see PRECAUTIONS, Lactation and Nursing ). Metabolism Ketorolac tromethamine is largely metabolized in the liver. The metabolic products are hydroxylated and conjugated forms of the parent drug. The products of metabolism, and some unchanged drug, are excreted in the urine. Excretion The principal route of elimination of ketorolac and its metabolites is renal. About 92% of a given dose is found in the urine, approximately 40% as metabolites and 60% as unchanged ketorolac. Approximately 6% of a dose is excreted in the feces. A single-dose study with 10 mg ketorolac tromethamine (n=9) demonstrated that the S-enantiomer is cleared approximately two times faster than the R-enantiomer and that the clearance was independent of the route of administration. This means that the ratio of S/R plasma concentrations decreases with time after each dose. There is little or no inversion of the R- to S- form in humans. The clearance of the racemate in normal subjects, elderly individuals and in hepatically and renally impaired patients is outlined in Table 2 . (see CLINICAL PHARMACOLOGY, Kinetics in Special Populations ).

The terminal half-life was 5.6 (4.0-7.9) hours. (See Kinetics in Special Populations f or use of Ketorolac Tromethamine Injection USP in pediatric patients). The half-life of ketorolac tromethamine S-enantiomer was approximately 2.5 hours (SD ± 0.4) compared with 5 hours (SD ± 1.7) for the R-enantiomer. In other studies, the half-life for the racemate has been reported to lie within the range of 5 to 6 hours. Accumulation Ketorolac tromethamine administered as an IV bolus every 6 hours for 5 days to healthy subjects (n= 13), showed no significant difference in C max on Day 1 and Day 5. Trough levels averaged 0.29 mcg/mL (SD ± 0.13) on Day 1 and 0.55 mcg/mL (SD ± 0.23) on Day 6. Steady state was approached after the fourth dose. Accumulation of ketorolac tromethamine has not been studied in special populations (geriatric, pediatric, renal failure patients or hepatic disease patients). Kinetics in Special Populations Geriatric Patients Based on single-dose data only, the half-life of the ketorolac tromethamine racemate increased from 5 to 7 hours in the elderly (65 to 78 years) compared with young healthy volunteers (24 to 35 years) (see Table 2 ). There was little difference in the C max for the two groups (elderly, 2.52 mcg/mL ± 0.77; young, 2.99 mcg/mL ± 1.03) (see PRECAUTIONS , Geriatric Use ). Pediatric Patients Following a single intravenous bolus dose of 0.5 mg/kg in 10 children 4 to 8 years old, the half-life was 6 hours (range: 3.5 to 10 h), the average clearance was 0.042 L/hr/kg and the Vd was 0.26 L/kg (range: 0.19 to 0.44 L/kg). In a second study, following a single intravenous dose of 0.6 mg/kg in 24 children 3 to 18 years old C max was 4.3 ± 2.6 µg/mL, T max was 10.25 ± 1.15 minutes, half-life was 3.8 ± 2.6 hours, Cl was 0.0678 L/hr/kg and Vd was 0.25 L/kg. The volume of distribution and clearance of ketorolac in pediatric patients was twice that observed in adult subjects (see Tables 1 and 2 ). There are no pharmacokinetic data available for ketorolac tromethamine administration by the IM route in pediatric patients. Renal Insufficiency Based on single-dose data only, the mean half-life of ketorolac tromethamine in renally impaired patients is between 6 and 19 hours and is dependent on the extent of the impairment. There is poor correlation between creatinine clearance and total ketorolac tromethamine clearance in the elderly and populations with renal impairment (r =0.5). In patients with renal disease, the AUC∞ of each enantiomer increased by approximately 100% compared with healthy volunteers. The volume of distribution doubles for the S-enantiomer and increases by 1/5th for the R-enantiomer. The increase in volume of distribution of ketorolac tromethamine implies an increase in unbound fraction. The AUC∞-ratio of the ketorolac tromethamine enantiomers in healthy subjects and patients remained similar, indicating there was no selective excretion of either enantiomer in patients compared to healthy subjects (see WARNINGS, Renal Effects and Table 2 ). Hepatic Insufficiency There was no significant difference in estimates of half-life, AUC and C max in 7 patients with liver disease compared to healthy volunteers (see PRECAUTIONS, Hepatic Effects and Table 2 ). Race Pharmacokinetic differences due to race have not been identified."],"clinical_pharmacology_table":["<table border=\"1\" width=\"60%\"><tbody align=\"center\"><tr><td colspan=\"7\"><content styleCode=\"bold\">TABLE 1 Table of Approximately Average Pharmacokinetic Parameters (Mean &#xB1; SD)Following Oral, Intramuscular and Intravenous Doses of Ketorolac Tromethamine</content></td></tr><tr><td rowspan=\"2\"><content styleCode=\"bold\">Pharmacokinetic Parameters (units)</content></td><td rowspan=\"2\"><content styleCode=\"bold\">Oral*10 mg</content></td><td colspan=\"3\"><content styleCode=\"bold\">Intramuscular&#x2020;</content></td><td colspan=\"2\"><content styleCode=\"bold\">Intravenous Bolus &#x2021;</content></td></tr><tr><td><content styleCode=\"bold\">15 mg</content></td><td><content styleCode=\"bold\">30 mg</content></td><td><content styleCode=\"bold\">60 mg</content></td><td><content styleCode=\"bold\">15 mg</content></td><td><content styleCode=\"bold\">30 mg</content></td></tr><tr><td align=\"left\">Bioavailability (extent)</td><td colspan=\"6\">100%</td></tr><tr><td align=\"left\">T<sub>max</sub><sup>1 </sup>(min)</td><td>44 &#xB1; 34</td><td>33 &#xB1; 21&#xA7;</td><td>44 &#xB1; 29</td><td>33 &#xB1; 21&#xA7;</td><td>1.1 &#xB1; 0.7&#xA7;</td><td>2.9 &#xB1; 1.8</td></tr><tr><td align=\"left\">C<sub>max</sub><sup>2</sup> (&#xB5;g/mL) [single-dose]</td><td>0.87 &#xB1; 0.22</td><td>1.14 &#xB1; 0.32&#xA7;</td><td>2.42 &#xB1; 0.68</td><td>4.55 &#xB1; 1.27&#xA7;</td><td>2.47 &#xB1; 0.51&#xA7;</td><td>4.65 &#xB1; 0.96</td></tr><tr><td align=\"left\">C<sub>max</sub> (&#xB5;g/mL) [steady state qid]</td><td>1.05 &#xB1; 0.26&#xA7;</td><td>1.56 &#xB1; 0.44&#xA7;</td><td>3.11 &#xB1; 0.87&#xA7;</td><td>N/A<sup>||</sup></td><td>3.09 &#xB1; 1.17&#xA7;</td><td>6.85 &#xB1; 2.61</td></tr><tr><td align=\"left\">C<sub>min</sub><sup>3 </sup>(&#xB5;g/mL) [steady state qid]</td><td>0.29 &#xB1; 0.07&#xA7;</td><td>0.47 &#xB1; 0.13&#xA7;</td><td>0.93 &#xB1; 0.26&#xA7;</td><td>N/A</td><td>0.61 &#xB1; 0.21&#xA7;</td><td>1.04 &#xB1; 0.35</td></tr><tr><td align=\"left\">C<sub>avg</sub><sup>4 </sup>(&#xB5;g/mL) [steady state qid]</td><td>0.59 &#xB1; 0.20&#xA7;</td><td>0.94 &#xB1; 0.29&#xA7;</td><td>1.88 &#xB1; 0.59&#xA7;</td><td>N/A</td><td>1.09 &#xB1; 0.30&#xA7;</td><td>2.17 &#xB1; 0.59</td></tr><tr><td align=\"left\">V&#xDF;<sup>5 </sup>(L/kg)</td><td colspan=\"4\">----------0.175 &#xB1; 0.039 ----------</td><td colspan=\"2\">0.210 &#xB1; 0.044</td></tr></tbody></table>","<table border=\"1\" width=\"90%\"><tbody align=\"center\"><tr><td colspan=\"6\"><content styleCode=\"bold\">Table 2  The Influence of Age, Liver and Kidney Function, on the Clearance and Terminal Half-life of Ketorolac Tromethamine (IM<sup>1</sup> and ORAL<sup>2</sup>) in Adult Populations</content></td></tr><tr><td> </td><td colspan=\"3\"><content styleCode=\"bold\">Total Clearance [in L/h/kg]<sup>3</sup></content></td><td colspan=\"2\"><content styleCode=\"bold\">Terminal Half-life [in hours]</content></td></tr><tr><td><content styleCode=\"bold\">Type of Subjects</content></td><td><content styleCode=\"bold\">IM Mean (range)</content></td><td colspan=\"2\"><content styleCode=\"bold\">ORAL Mean (range)</content></td><td><content styleCode=\"bold\">IM Mean (range)</content></td><td><content styleCode=\"bold\">ORAL Mean (range)</content></td></tr><tr><td align=\"left\">Normal Subjects  IM (n=54)  mean age=32, range=18-60  Oral (n=77)  mean age=32, range=20-60</td><td>0.023  (0.010-0.046)</td><td colspan=\"2\">0.025  (0.013-0.050)</td><td>5.3  (3.5-9.2)</td><td>5.3  (2.4-9.0)</td></tr><tr><td align=\"left\">Healthy Elderly Subjects  IM (n=13), Oral (n=12)  mean age=72, range=65-78</td><td>0.019  (0.013-0.034)</td><td colspan=\"2\">0.024  (0.018-0.034)</td><td>7.0  (4.7-8.6)</td><td>6.1  (4.3-7.6)</td></tr><tr><td align=\"left\">Patients with Hepatic  Dysfunction IM and Oral  (n=7)  mean age=51, range=43-64</td><td>0.029  (0.013-0.066)</td><td colspan=\"2\">0.033  (0.019-0.051)</td><td>5.4  (2.2-6.9)</td><td>4.5  (1.6-7.6)</td></tr><tr><td align=\"left\">Patients with Renal  Impairment  IM (n=25), Oral (n=9)  serum creatinine=1.9-5.0  mg/dL,  mean age (IM)=54,  range=35-71  mean age (Oral)=57,  range=39-70</td><td>0.015  (0.005-0.043)</td><td colspan=\"2\">0.016  (0.007-0.052)</td><td>10.3  (5.9-19.2)</td><td>10.8  (3.4-18.9)</td></tr><tr><td align=\"left\">Renal Dialysis Patients  IM and Oral (n=9)  mean age=40, range=27-63</td><td>0.016  (0.003-0.036)</td><td colspan=\"2\">__</td><td>13.6  (8.0-39.1)</td><td>__</td></tr></tbody></table>"],"clinical_studies":["Clinical Studies Adult Patients The analgesic efficacy of intramuscularly, intravenously and orally administered ketorolac tromethamine was investigated in two postoperative pain models: general surgery (orthopedic, gynecologic and abdominal) and oral surgery (removal of impacted third molars). The studies were double-blind, single- and multiple-dose, parallel trial designs in patients with moderate to severe pain at baseline. Ketorolac tromethamine injection was compared as follows: IM to meperidine or morphine administered intramuscularly and IV to morphine administered either directly IV or through a PCA (Patient-Controlled Analgesia) pump. Short-Term Use (up to 5 days) Studies In adults, the comparisons of intramuscular administration during the first hour, the onset of analgesic action was similar for ketorolac tromethamine and the narcotics, but the duration of analgesia was longer with ketorolac tromethamine than with the opioid comparators meperidine or morphine. In a multi-dose, postoperative (general surgery) double-blind trial of Ketorolac 30 mg IM versus morphine 6 and 12 mg IM, each drug given on an as needed basis for up to 5 days, the overall analgesic effect of Ketorolac 30 mg IM was between that of morphine 6 and 12 mg. The majority of patients treated with either ketorolac tromethamine or morphine were dosed for up to 3 days; a small percentage of patients received 5 days of dosing. In clinical settings where preoperative morphine was allowed, Ketorolac 30 mg IV, given once or twice as needed, provided analgesia comparable to morphine 4 mg IV once or twice as needed. There was relatively limited experience with 5 consecutive days of Ketorolac IV use in controlled clinical trials, as most patients were given the drug for 3 days or less. The adverse events seen with IV-administered ketorolac tromethamine were similar to those observed with IM-administered ketorolac tromethamine, as would be expected based on the similar pharmacokinetics and bioequivalence (AUC, clearance, plasma half-life) of IV and IM routes of ketorolac tromethamine administration. Pediatric Patients The analgesic efficacy of single doses of ketorolac tromethamine injection had been demonstrated by showing a decrease in the need for supplemental narcotic in pediatric patients receiving ketorolac as compared to placebo. See discussion of these results under Clinical Studies With Concomitant Use of Opioids below. Clinical Studies with Concomitant Use of Opioids Adult Patients Clinical studies in postoperative pain management have demonstrated that ketorolac tromethamine injection, when used in combination with opioids, significantly reduced opioid consumption. This combination may be useful in the subpopulation of patients especially prone to opioid-related complications. Ketorolac tromethamine and narcotics should not be administered in the same syringe. In a postoperative study, where all patients received morphine by a PCA device, patients treated with ketorolac intravenously as fixed intermittent boluses (e.g., 30 mg initial dose followed by 15 mg q3h), required significantly less morphine (26%) than the placebo group. Analgesia was significantly superior, at various postdosing pain assessment times, in the patients receiving Ketorolac intravenously plus PCA morphine as compared to patients receiving PCA-administered morphine alone. Pediatric Patients Ketorolac tromethamine intramuscular injection reduced the need for supplemental opioid (fentanyl) when a 1 mg/kg dose was administered immediately following tonsillectomy compared to saline controls (see WARNINGS , Hemorrhage ). In another study, when a single bolus dose of 0.9 mg/kg of ketorolac tromethamine intravenous injection was given to pediatric patients ages 5 to 12 years, compared to saline, a reduction in supplemental opioid was needed following various surgical procedures. In a third study less, supplemental morphine was needed in pediatric patients ages 8 to 16 years, who received a 0.8 mg/kg IV injection of ketorolac tromethamine in conjunction with morphine following orthopedic surgical procedures, compared to morphine alone. In a study in pediatric patients ages 3 to 12 years, ketorolac tromethamine intravenous injection demonstrated a slower onset of analgesia, but a longer duration of action compared to morphine. There is limited data available to support the use of multiple doses of ketorolac tromethamine injection in pediatric patients. Postmarketing Surveillance Study A large postmarketing observational, non-randomized study, involving approximately 10,000 patients receiving ketorolac tromethamine, demonstrated that the risk of clinically serious gastrointestinal (GI) bleeding was dose-dependent (see Tables 3A and 3B ).

IN ADULTS THE USE OF KETOROLAC TROMETHAMINE TABLETS IS ONLY INDICATED AS CONTINUATION THERAPY TO KETOROLAC TROMETHAMINE INJECTION USP. Ketorolac Tromethamine Injection, USP Adult Patients Ketorolac tromethamine injection, USP may be used as a single, or multiple dose, on a regular or prn schedule for the management of moderately severe, acute pain that requires analgesia at the opioid level, usually in a postoperative setting. Hypovolemia should be corrected prior to the administration of ketorolac tromethamine (see WARNINGS , Renal Effects ). Patients should be switched to alternative analgesics as soon as possible, but ketorolac tromethamine therapy is not to exceed 5 days. When administering ketorolac tromethamine injection, USP the IV bolus must be given over no less than 15 seconds. The IM administration should be given slowly and deeply into the muscle. The analgesic effect begins in ~30 minutes with maximum effect in 1 to 2 hours after dosing IV or IM. Duration of analgesic effect is usually 4 to 6 hours. Single-Dose Treatment: The following regimen should be limited to single administration use only Adult Patients IM Dosing • Patients <65 years of age : One dose of 60 mg. • Patients ≥65 years of age, renally impaired and/or less than 50 kg (110 lbs.) of body weight : One dose of 30 mg. IV Dosing • Patients <65 years of age : One dose of 30 mg. • Patients ≥65 years of age, renally impaired and/or less than 50 kg (110 lbs.) of body weight : One dose of 15 mg. Pediatric Patients (2 to 16 years of age) The pediatric population should receive only a single dose of ketorolac tromethamine injection, USP, as follows: IM Dosing One dose of 1 mg/kg up to a maximum of 30 mg. IV Dosing One dose of 0.5 mg/kg up to a maximum of 15 mg. Multiple Dose Treatment (IV or IM) In Adults • Patients <65 years of age : The recommended dose is 30 mg ketorolac tromethamine injection, USP every 6 hours. The maximum daily dose should not exceed 120 mg. • For Patients ≥65 years of age, renally impaired patients (see WARNINGS ) and patients less than 50 kg (110 lbs.) : The recommended dose is 15 mg ketorolac tromethamine injection every 6 hours. The maximum daily dose for these populations should not exceed 60 mg. For breakthrough pain do not increase the dose or the frequency of ketorolac tromethamine. Consideration should be given to supplementing these regimens with low doses of opioids prn unless otherwise contraindicated. Pharmaceutical Information for Ketorolac Tromethamine Injection Parenteral drug products should be inspected visually for particulate matter and discoloration prior to administration whenever solution and container permit. Ketorolac tromethamine injection, USP should not be mixed in a small volume (eg, in a syringe) with morphine sulfate, meperidine hydrochloride, promethazine hydrochloride or hydroxyzine hydrochloride; this will result in precipitation of ketorolac from solution. Shortening the recommended dosing intervals may result in increased frequency and severity of adverse reactions. In adults, the maximum combined duration of use (parenteral and oral ketorolac tromethamine) is limited to 5 days."],"drug_interactions":["Drug Interactions Ketorolac is highly bound to human plasma protein (mean 99.2%). Warfarin, Digoxin, Salicylate and Heparin The in vitro binding of warfarin to plasma proteins is only slightly reduced by ketorolac tromethamine (99.5% control vs 99.3%) when ketorolac plasma concentrations reach 5 to 10 µg/mL. Ketorolac does not alter digoxin protein binding. In vitro studies indicate that, at therapeutic concentrations of salicylate (300 µg/mL), the binding of ketorolac was reduced from approximately 99.2% to 97.5%, representing a potential two-fold increase in unbound ketorolac plasma levels. Therapeutic concentrations of digoxin, warfarin, ibuprofen, naproxen, piroxicam, acetaminophen, phenytoin and tolbutamide did not alter ketorolac tromethamine protein binding. In a study involving 12 adult volunteers, ketorolac tromethamine tablets were co-administered with a single dose of 25 mg warfarin , causing no significant changes in pharmacokinetics or pharmacodynamics of warfarin. In another study, ketorolac tromethamine injection, USP was given with two doses of 5000 U of heparin to 11 healthy volunteers, resulting in a mean template bleeding time of 6.4 minutes (3.2 to 11.4 min) compared to a mean of 6.0 minutes (3.4 to 7.5 min) for heparin alone and 5.1 minutes (3.5 to 8.5 min) for placebo. Although these results do not indicate a significant interaction between ketorolac tromethamine and warfarin or heparin, the administration of ketorolac tromethamine to patients taking anticoagulants should be done extremely cautiously, and patients should be closely monitored (see WARNINGS and PRECAUTIONS ). Furosemide Ketorolac tromethamine injection reduced the diuretic response to furosemide in normovolemic healthy subjects by approximately 20% (mean sodium and urinary output decreased 17%). Probenecid Concomitant administration of ketorolac tromethamine tablets and probenecid resulted in decreased clearance of ketorolac and significant increases in ketorolac plasma levels (total AUC increased approximately threefold from 5.4 to 17.8 µg/h/mL) and terminal half-life increased approximately twofold from 6.6 to 15.1 hours. Therefore, concomitant use of ketorolac tromethamine and probenecid is contraindicated. Lithium Inhibition of renal lithium clearance, leading to an increase in plasma lithium concentration, has been reported with some prostaglandin synthesis inhibiting drugs. The effect of ketorolac tromethamine on plasma lithium has not been studied, but cases of increased lithium plasma levels during ketorolac tromethamine therapy have been reported. Methotrexate Concomitant administration of methotrexate and some NSAIDs has been reported to reduce the clearance of methotrexate, enhancing the toxicity of methotrexate. The effect of ketorolac tromethamine on methotrexate clearance has not been studied. Non-depolarizing Muscle Relaxants In postmarketing experience there have been reports of a possible interaction between ketorolac tromethamine injection, USP and non-depolarizing muscle relaxants that resulted in apnea. The concurrent use of ketorolac tromethamine with muscle relaxants has not been formally studied. ACE Inhibitors Concomitant use of ACE inhibitors may increase the risk of renal impairment, particularly in volume depleted patients. Antiepileptic Drugs Sporadic cases of seizures have been reported during concomitant use of ketorolac tromethamine and antiepileptic drugs (phenytoin, carbamazepine). Psychoactive Drugs Hallucinations have been reported when ketorolac tromethamine was used in patients taking psychoactive drugs (fluoxetine, thiothixene, alprazolam). Morphine Ketorolac tromethamine injection has been administered concurrently with morphine in several clinical trials of postoperative pain without evidence of adverse interactions. Do not mix ketorolac tromethamine and morphine in the same syringe. There is no evidence in animal or human studies that ketorolac tromethamine induces or inhibits hepatic enzymes capable of metabolizing itself or other drugs."],"effective_time":"20201021","general_precautions":["General Hepatic Effects Ketorolac tromethamine should be used with caution in patients with impaired hepatic function or a history of liver disease. Treatment with ketorolac tromethamine may cause elevations of liver enzymes, and, in patients with pre-existing liver dysfunction, it may lead to the development of a more severe hepatic reaction. The administration of ketorolac tromethamine should be discontinued in patients in whom an abnormal liver test has occurred as a result of ketorolac tromethamine therapy. Hematologic Effects Ketorolac tromethamine inhibits platelet aggregation and may prolong bleeding time; therefore, it is contraindicated as a preoperative medication, and caution should be used when hemostasis is critical. Unlike aspirin, the inhibition of platelet function by ketorolac tromethamine disappears within 24 to 48 hours after the drug is discontinued. Ketorolac tromethamine does not appear to affect platelet count, prothrombin time (PT) or partial thromboplastin time (PTT). In controlled clinical studies, where ketorolac tromethamine was administered intramuscularly or intravenously postoperatively, the incidence of clinically significant postoperative bleeding was 0.4% for ketorolac tromethamine compared to 0.2% in the control groups receiving narcotic analgesics."],"geriatric_use":["Geriatric Use (≥65 years of age) Because ketorolac tromethamine may be cleared more slowly by the elderly (see CLINICAL PHARMACOLOGY ) who are also more sensitive to the adverse effects of NSAIDs (see WARNINGS, Renal Effects ), extra caution and reduced dosages (see DOSAGE AND ADMINISTRATION ) must be used when treating the elderly with ketorolac tromethamine injection. The lower end of the ketorolac tromethamine injection dosage range is recommended for patients over 65 years of age, and total daily dose is not to exceed 60 mg.

This implies that the pharmacokinetics of ketorolac tromethamine in humans, following single or multiple IM, IV or recommended oral doses of ketorolac tromethamine, are linear. At the higher recommended doses, there is a proportional increase in the concentrations of free and bound racemate. Distribution The mean apparent volume (V(beta)) of ketorolac tromethamine following complete distribution was approximately 13 liters. This parameter was determined from single-dose data. The ketorolac tromethamine racemate has been shown to be highly protein bound (99%). Nevertheless, even plasma concentrations as high as 10 µg/mL will only occupy approximately 5% of the albumin binding sites. Thus, the unbound fraction for each enantiomer will be constant over the therapeutic range. A decrease in serum albumin, however, will result in increased free drug concentrations. Ketorolac tromethamine is excreted in human milk (see PRECAUTIONS, Lactation and Nursing ). Metabolism Ketorolac tromethamine is largely metabolized in the liver. The metabolic products are hydroxylated and conjugated forms of the parent drug. The products of metabolism, and some unchanged drug, are excreted in the urine. Excretion The principal route of elimination of ketorolac and its metabolites is renal. About 92% of a given dose is found in the urine, approximately 40% as metabolites and 60% as unchanged ketorolac. Approximately 6% of a dose is excreted in the feces. A single-dose study with 10 mg ketorolac tromethamine (n=9) demonstrated that the S-enantiomer is cleared approximately two times faster than the R-enantiomer and that the clearance was independent of the route of administration. This means that the ratio of S/R plasma concentrations decreases with time after each dose. There is little or no inversion of the R- to S- form in humans. The clearance of the racemate in normal subjects, elderly individuals and in hepatically and renally impaired patients is outlined in Table 2 .

The half-life of ketorolac tromethamine S-enantiomer was approximately 2.5 hours (SD ± 0.4) compared with 5 hours (SD ± 1.7) for the R-enantiomer. In other studies, the half-life for the racemate has been reported to lie within the range of 5 to 6 hours. Accumulation Ketorolac tromethamine administered as an IV bolus every 6 hours for 5 days to healthy subjects (n= 13), showed no significant difference in C max on Day 1 and Day 5. Trough levels averaged 0.29 mcg/mL (SD ± 0.13) on Day 1 and 0.55 mcg/mL (SD ± 0.23) on Day 6. Steady state was approached after the fourth dose. Accumulation of ketorolac tromethamine has not been studied in special populations (geriatric, pediatric, renal failure patients or hepatic disease patients). Kinetics in Special Populations Geriatric Patients Based on single-dose data only, the half-life of the ketorolac tromethamine racemate increased from 5 to 7 hours in the elderly (65 to 78 years) compared with young healthy volunteers (24 to 35 years) (see Table 2 ). There was little difference in the C max for the two groups (elderly, 2.52 mcg/mL ± 0.77; young, 2.99 mcg/mL ± 1.03) (see PRECAUTIONS , Geriatric Use ). Pediatric Patients Following a single intravenous bolus dose of 0.5 mg/kg in 10 children 4 to 8 years old, the half-life was 6 hours (range: 3.5 to 10 h), the average clearance was 0.042 L/hr/kg and the Vd was 0.26 L/kg (range: 0.19 to 0.44 L/kg). In a second study, following a single intravenous dose of 0.6 mg/kg in 24 children 3 to 18 years old C max was 4.3 ± 2.6 µg/mL, T max was 10.25 ± 1.15 minutes, half-life was 3.8 ± 2.6 hours, Cl was 0.0678 L/hr/kg and Vd was 0.25 L/kg. The volume of distribution and clearance of ketorolac in pediatric patients was twice that observed in adult subjects (see Tables 1 and 2 ). There are no pharmacokinetic data available for ketorolac tromethamine administration by the IM route in pediatric patients. Renal Insufficiency Based on single-dose data only, the mean half-life of ketorolac tromethamine in renally impaired patients is between 6 and 19 hours and is dependent on the extent of the impairment. There is poor correlation between creatinine clearance and total ketorolac tromethamine clearance in the elderly and populations with renal impairment (r =0.5). In patients with renal disease, the AUC∞ of each enantiomer increased by approximately 100% compared with healthy volunteers. The volume of distribution doubles for the S-enantiomer and increases by 1/5th for the R-enantiomer. The increase in volume of distribution of ketorolac tromethamine implies an increase in unbound fraction. The AUC∞-ratio of the ketorolac tromethamine enantiomers in healthy subjects and patients remained similar, indicating there was no selective excretion of either enantiomer in patients compared to healthy subjects (see WARNINGS, Renal Effects and Table 2 ). Hepatic Insufficiency There was no significant difference in estimates of half-life, AUC and C max in 7 patients with liver disease compared to healthy volunteers (see PRECAUTIONS, Hepatic Effects and Table 2 ). Race Pharmacokinetic differences due to race have not been identified."],"pharmacokinetics_table":["<table border=\"1\" width=\"60%\"><tbody align=\"center\"><tr><td colspan=\"7\"><content styleCode=\"bold\">TABLE 1 Table of Approximately Average Pharmacokinetic Parameters (Mean &#xB1; SD)Following Oral, Intramuscular and Intravenous Doses of Ketorolac Tromethamine</content></td></tr><tr><td rowspan=\"2\"><content styleCode=\"bold\">Pharmacokinetic Parameters (units)</content></td><td rowspan=\"2\"><content styleCode=\"bold\">Oral*10 mg</content></td><td colspan=\"3\"><content styleCode=\"bold\">Intramuscular&#x2020;</content></td><td colspan=\"2\"><content styleCode=\"bold\">Intravenous Bolus &#x2021;</content></td></tr><tr><td><content styleCode=\"bold\">15 mg</content></td><td><content styleCode=\"bold\">30 mg</content></td><td><content styleCode=\"bold\">60 mg</content></td><td><content styleCode=\"bold\">15 mg</content></td><td><content styleCode=\"bold\">30 mg</content></td></tr><tr><td align=\"left\">Bioavailability (extent)</td><td colspan=\"6\">100%</td></tr><tr><td align=\"left\">T<sub>max</sub><sup>1 </sup>(min)</td><td>44 &#xB1; 34</td><td>33 &#xB1; 21&#xA7;</td><td>44 &#xB1; 29</td><td>33 &#xB1; 21&#xA7;</td><td>1.1 &#xB1; 0.7&#xA7;</td><td>2.9 &#xB1; 1.8</td></tr><tr><td align=\"left\">C<sub>max</sub><sup>2</sup> (&#xB5;g/mL) [single-dose]</td><td>0.87 &#xB1; 0.22</td><td>1.14 &#xB1; 0.32&#xA7;</td><td>2.42 &#xB1; 0.68</td><td>4.55 &#xB1; 1.27&#xA7;</td><td>2.47 &#xB1; 0.51&#xA7;</td><td>4.65 &#xB1; 0.96</td></tr><tr><td align=\"left\">C<sub>max</sub> (&#xB5;g/mL) [steady state qid]</td><td>1.05 &#xB1; 0.26&#xA7;</td><td>1.56 &#xB1; 0.44&#xA7;</td><td>3.11 &#xB1; 0.87&#xA7;</td><td>N/A<sup>||</sup></td><td>3.09 &#xB1; 1.17&#xA7;</td><td>6.85 &#xB1; 2.61</td></tr><tr><td align=\"left\">C<sub>min</sub><sup>3 </sup>(&#xB5;g/mL) [steady state qid]</td><td>0.29 &#xB1; 0.07&#xA7;</td><td>0.47 &#xB1; 0.13&#xA7;</td><td>0.93 &#xB1; 0.26&#xA7;</td><td>N/A</td><td>0.61 &#xB1; 0.21&#xA7;</td><td>1.04 &#xB1; 0.35</td></tr><tr><td align=\"left\">C<sub>avg</sub><sup>4 </sup>(&#xB5;g/mL) [steady state qid]</td><td>0.59 &#xB1; 0.20&#xA7;</td><td>0.94 &#xB1; 0.29&#xA7;</td><td>1.88 &#xB1; 0.59&#xA7;</td><td>N/A</td><td>1.09 &#xB1; 0.30&#xA7;</td><td>2.17 &#xB1; 0.59</td></tr><tr><td align=\"left\">V&#xDF;<sup>5 </sup>(L/kg)</td><td colspan=\"4\">----------0.175 &#xB1; 0.039 ----------</td><td colspan=\"2\">0.210 &#xB1; 0.044</td></tr></tbody></table>","<table border=\"1\" width=\"90%\"><tbody align=\"center\"><tr><td colspan=\"6\"><content styleCode=\"bold\">Table 2  The Influence of Age, Liver and Kidney Function, on the Clearance and Terminal Half-life of Ketorolac Tromethamine (IM<sup>1</sup> and ORAL<sup>2</sup>) in Adult Populations</content></td></tr><tr><td> </td><td colspan=\"3\"><content styleCode=\"bold\">Total Clearance [in L/h/kg]<sup>3</sup></content></td><td colspan=\"2\"><content styleCode=\"bold\">Terminal Half-life [in hours]</content></td></tr><tr><td><content styleCode=\"bold\">Type of Subjects</content></td><td><content styleCode=\"bold\">IM Mean (range)</content></td><td colspan=\"2\"><content styleCode=\"bold\">ORAL Mean (range)</content></td><td><content styleCode=\"bold\">IM Mean (range)</content></td><td><content styleCode=\"bold\">ORAL Mean (range)</content></td></tr><tr><td align=\"left\">Normal Subjects  IM (n=54)  mean age=32, range=18-60  Oral (n=77)  mean age=32, range=20-60</td><td>0.023  (0.010-0.046)</td><td colspan=\"2\">0.025  (0.013-0.050)</td><td>5.3  (3.5-9.2)</td><td>5.3  (2.4-9.0)</td></tr><tr><td align=\"left\">Healthy Elderly Subjects  IM (n=13), Oral (n=12)  mean age=72, range=65-78</td><td>0.019  (0.013-0.034)</td><td colspan=\"2\">0.024  (0.018-0.034)</td><td>7.0  (4.7-8.6)</td><td>6.1  (4.3-7.6)</td></tr><tr><td align=\"left\">Patients with Hepatic  Dysfunction IM and Oral  (n=7)  mean age=51, range=43-64</td><td>0.029  (0.013-0.066)</td><td colspan=\"2\">0.033  (0.019-0.051)</td><td>5.4  (2.2-6.9)</td><td>4.5  (1.6-7.6)</td></tr><tr><td align=\"left\">Patients with Renal  Impairment  IM (n=25), Oral (n=9)  serum creatinine=1.9-5.0  mg/dL,  mean age (IM)=54,  range=35-71  mean age (Oral)=57,  range=39-70</td><td>0.015  (0.005-0.043)</td><td colspan=\"2\">0.016  (0.007-0.052)</td><td>10.3  (5.9-19.2)</td><td>10.8  (3.4-18.9)</td></tr><tr><td align=\"left\">Renal Dialysis Patients  IM and Oral (n=9)  mean age=40, range=27-63</td><td>0.016  (0.003-0.036)</td><td colspan=\"2\">__</td><td>13.6  (8.0-39.1)</td><td>__</td></tr></tbody></table>"],"precautions":["PRECAUTIONS General Hepatic Effects Ketorolac tromethamine should be used with caution in patients with impaired hepatic function or a history of liver disease. Treatment with ketorolac tromethamine may cause elevations of liver enzymes, and, in patients with pre-existing liver dysfunction, it may lead to the development of a more severe hepatic reaction. The administration of ketorolac tromethamine should be discontinued in patients in whom an abnormal liver test has occurred as a result of ketorolac tromethamine therapy. Hematologic Effects Ketorolac tromethamine inhibits platelet aggregation and may prolong bleeding time; therefore, it is contraindicated as a preoperative medication, and caution should be used when hemostasis is critical. Unlike aspirin, the inhibition of platelet function by ketorolac tromethamine disappears within 24 to 48 hours after the drug is discontinued. Ketorolac tromethamine does not appear to affect platelet count, prothrombin time (PT) or partial thromboplastin time (PTT). In controlled clinical studies, where ketorolac tromethamine was administered intramuscularly or intravenously postoperatively, the incidence of clinically significant postoperative bleeding was 0.4% for ketorolac tromethamine compared to 0.2% in the control groups receiving narcotic analgesics. Information for Patients Ketorolac tromethamine is a potent NSAID and may cause serious side effects such as gastrointestinal bleeding or kidney failure, which may result in hospitalization and even fatal outcome. Physicians, when prescribing ketorolac tromethamine, should inform their patients or their guardians of the potential risks of ketorolac tromethamine treatment (see BOXED WARNING, WARNINGS, PRECAUTIONS and ADVERSE REACTIONS sections). Advise patients not to give Ketorolac Tromethamine Tablets to other family members and to discard any unused drug. Remember that the total duration of ketorolac tromethamine therapy is not to exceed 5 (five) days in adults or single dose in pediatric patients ages 2 to 16 years. Serious Skin Reactions, including DRESS Advise patients to stop taking ketorolac tromethamine immediately if they develop any type of rash or fever and to contact their healthcare provider as soon as possible [see Warnings ]. Cardiovascular Thrombotic Events Advise patients to be alert for the symptoms of cardiovascular thrombotic events, including chest pain, shortness of breath, weakness, or slurring of speech, and to report any of these symptoms to their health care provider immediately (see WARNINGS ). Heart Failure and Edema Advise patients to be alert for the symptoms of congestive heart failure including shortness of breath, unexplained weight gain, or edema and to contact their healthcare provider if such symptoms occur (see WARNINGS ). Drug Interactions Ketorolac is highly bound to human plasma protein (mean 99.2%). Warfarin, Digoxin, Salicylate and Heparin The in vitro binding of warfarin to plasma proteins is only slightly reduced by ketorolac tromethamine (99.5% control vs 99.3%) when ketorolac plasma concentrations reach 5 to 10 µg/mL. Ketorolac does not alter digoxin protein binding. In vitro studies indicate that, at therapeutic concentrations of salicylate (300 µg/mL), the binding of ketorolac was reduced from approximately 99.2% to 97.5%, representing a potential two-fold increase in unbound ketorolac plasma levels. Therapeutic concentrations of digoxin, warfarin, ibuprofen, naproxen, piroxicam, acetaminophen, phenytoin and tolbutamide did not alter ketorolac tromethamine protein binding. In a study involving 12 adult volunteers, ketorolac tromethamine tablets were co-administered with a single dose of 25 mg warfarin , causing no significant changes in pharmacokinetics or pharmacodynamics of warfarin. In another study, ketorolac tromethamine injection, USP was given with two doses of 5000 U of heparin to 11 healthy volunteers, resulting in a mean template bleeding time of 6.4 minutes (3.2 to 11.4 min) compared to a mean of 6.0 minutes (3.4 to 7.5 min) for heparin alone and 5.1 minutes (3.5 to 8.5 min) for placebo. Although these results do not indicate a significant interaction between ketorolac tromethamine and warfarin or heparin, the administration of ketorolac tromethamine to patients taking anticoagulants should be done extremely cautiously, and patients should be closely monitored (see WARNINGS and PRECAUTIONS ). Furosemide Ketorolac tromethamine injection reduced the diuretic response to furosemide in normovolemic healthy subjects by approximately 20% (mean sodium and urinary output decreased 17%). Probenecid Concomitant administration of ketorolac tromethamine tablets and probenecid resulted in decreased clearance of ketorolac and significant increases in ketorolac plasma levels (total AUC increased approximately threefold from 5.4 to 17.8 µg/h/mL) and terminal half-life increased approximately twofold from 6.6 to 15.1 hours. Therefore, concomitant use of ketorolac tromethamine and probenecid is contraindicated. Lithium Inhibition of renal lithium clearance, leading to an increase in plasma lithium concentration, has been reported with some prostaglandin synthesis inhibiting drugs. The effect of ketorolac tromethamine on plasma lithium has not been studied, but cases of increased lithium plasma levels during ketorolac tromethamine therapy have been reported. Methotrexate Concomitant administration of methotrexate and some NSAIDs has been reported to reduce the clearance of methotrexate, enhancing the toxicity of methotrexate. The effect of ketorolac tromethamine on methotrexate clearance has not been studied. Non-depolarizing Muscle Relaxants In postmarketing experience there have been reports of a possible interaction between ketorolac tromethamine injection, USP and non-depolarizing muscle relaxants that resulted in apnea. The concurrent use of ketorolac tromethamine with muscle relaxants has not been formally studied. ACE Inhibitors Concomitant use of ACE inhibitors may increase the risk of renal impairment, particularly in volume depleted patients. Antiepileptic Drugs Sporadic cases of seizures have been reported during concomitant use of ketorolac tromethamine and antiepileptic drugs (phenytoin, carbamazepine). Psychoactive Drugs Hallucinations have been reported when ketorolac tromethamine was used in patients taking psychoactive drugs (fluoxetine, thiothixene, alprazolam). Morphine Ketorolac tromethamine injection has been administered concurrently with morphine in several clinical trials of postoperative pain without evidence of adverse interactions. Do not mix ketorolac tromethamine and morphine in the same syringe. There is no evidence in animal or human studies that ketorolac tromethamine induces or inhibits hepatic enzymes capable of metabolizing itself or other drugs. Carcinogenesis, Mutagenesis and Impairment of Fertility An 18 month study in mice with oral doses of ketorolac tromethamine at 2 mg/kg/day (0.9 times the human systemic exposure at the recommended IM or IV dose of 30 mg qid, based on area-under-the-plasma-concentration curve [AUC]), and a 24 month study in rats at 5 mg/kg/day (0.5 times the human AUC) showed no evidence of tumorigenicity. Ketorolac tromethamine was not mutagenic in the Ames test, unscheduled DNA synthesis and repair, and in forward mutation assays. Ketorolac tromethamine did not cause chromosome breakage in the in vivo mouse micronucleus assay. At 1590 µg/mL and at higher concentrations, ketorolac tromethamine increased the incidence of chromosomal aberrations in Chinese hamster ovarian cells. Impairment of fertility did not occur in male or female rats at oral doses of 9 mg/kg (0.9 times the human AUC) and 16 mg/kg (1.6 times the human AUC) of ketorolac tromethamine, respectively. Fetal Toxicity Inform pregnant women to avoid use of ketorolac tromethamine and other NSAIDs startingat 30 weeks gestation because of the risk of the premature closing of the fetal ductus arteriosus. If treatment with ketorolac tromethamine is needed for a pregnant woman between about 20 to 30 weeks gestation, advise her that she may need to be monitored for oligohydramnios, if treatment continues for longer than 48 hours [see WARNING S; Fetal Toxicity, PRECAUTIONS ; Pregnancy]. Pregnancy Risk Summary Use of NSAIDs, including ketorolac tromethamine, can cause premature closure of the fetal ductus arteriosus and fetal renal dysfunction leading to oligohydramnios and, in some cases, neonatal renal impairment. Because of these risks, limit dose and duration of ketorolac tromethamine use between about 20 and 30 weeks of gestation and avoid ketorolactromethamine use at about 30 weeks of gestation and later in pregnancy [see WARNINGS ; Fetal Toxicity]. Premature Closure of Fetal Ductus Arteriosus Use of NSAIDs, including ketorolac tromethamine, at about 30 weeks gestation or later in pregnancy increases the risk of premature closure of the fetal ductus arteriosus. Oligohydramnios/Neonatal Renal Impairment Use of NSAIDs at about 20 weeks gestation or later in pregnancy has been associated with cases of fetal renal dysfunction leading to oligohydramnios, and in some cases, neonatal renal impairment. Clinical Considerations Fetal/Neonatal Adverse Reactions Premature Closure of Fetal Ductus Arteriosus: Avoid use of NSAIDs in women at about 30 weeks gestation and later in pregnancy, because NSAIDs, including ketorolac tromethamine, can cause premature closure of the fetal ductus arteriosus (see WARNINGS ; Fetal Toxicity). Oligohydramnios/Neonatal Renal Impairment If an NSAID is necessary at about 20 weeks gestation or later in pregnancy, limit the use to the lowest effective dose and shortest duration possible. If ketorolac tromethamine treatment extends beyond 48 hours, consider monitoring with ultrasound for oligohydramnios. If oligohydramnios occurs, discontinue ketorolac tromethamine and follow up according to clinical practice (see WARNINGS ; Fetal Toxicity). Labor and Delivery The use of ketorolac tromethamine is contraindicated in labor and delivery because, through its prostaglandin synthesis inhibitory effect, it may adversely affect fetal circulation and inhibit uterine contractions, thus increasing the risk of uterine hemorrhage (see CONTRAINDICATIONS ). Lactation and Nursing After a single administration of 10 mg ketorolac tromethamine tablets to humans, the maximum milk concentration observed was 7.3 ng/mL, and the maximum milk-to-plasma ratio was 0.037. After 1 day of dosing (qid), the maximum milk concentration was 7.9 ng/mL, and the maximum milk-to-plasma ratio was 0.025. Because of the possible adverse effects of prostaglandin-inhibiting drugs on neonates, use in nursing mothers is CONTRAINDICATED. Pediatric Use Safety and effectiveness of single doses of ketorolac tromethamine injection have been established in pediatric patients between the ages of 2 and 16 years. Ketorolac tromethamine injection has been shown to be effective in the management of moderately severe acute pain that requires analgesia at the opioid level, usually in a postoperative setting. Safety and efficacy in pediatric patients below the age of 2 have not been established. Therefore, ketorolac tromethamine injection is not recommended in pediatric patients below the age of 2. The risk of bleeding was greater in those patients administered ketorolac tromethamine injection following tonsillectomy. Physicians should consider the increased risk of bleeding before deciding to administer ketorolac tromethamine injection in patients following tonsillectomy (see WARNINGS , Hemorrhage and Pediatrics and Tonsillectomy ). The risks identified in the adult population with ketorolac tromethamine injection use also apply to pediatric patients. Therefore, consult the CONTRAINDICATIONS , WARNING , PRECAUTIONS , and ADVERSE REACTIONS sections when prescribing ketorolac tromethamine injection to pediatric patients. Geriatric Use (≥65 years of age) Because ketorolac tromethamine may be cleared more slowly by the elderly (see CLINICAL PHARMACOLOGY ) who are also more sensitive to the adverse effects of NSAIDs (see WARNINGS, Renal Effects ), extra caution and reduced dosages (see DOSAGE AND ADMINISTRATION ) must be used when treating the elderly with ketorolac tromethamine injection. The lower end of the ketorolac tromethamine injection dosage range is recommended for patients over 65 years of age, and total daily dose is not to exceed 60 mg. The incidence and severity of gastrointestinal complications increases with increasing dose of, and duration of treatment with, ketorolac tromethamine."],"pregnancy":["Pregnancy Risk Summary Use of NSAIDs, including ketorolac tromethamine, can cause premature closure of the fetal ductus arteriosus and fetal renal dysfunction leading to oligohydramnios and, in some cases, neonatal renal impairment.

NSAIDs can cause serious side effects, including: Increased risk of a heart attack or stroke that can lead to death. This risk may happen early in treatment and may increase: with increasing doses of NSAIDs with longer use of NSAIDs Do not take NSAIDs right before or after a heart surgery called a \"coronary artery bypass graft (CABG)\". Avoid taking NSAIDs after a recent heart attack, unless your healthcare provider tells you to. You may have an increased risk of another heart attack if you take NSAIDs after a recent heart attack. Increased risk of bleeding, ulcers, and tears (perforation) of the esophagus (tube leading from the mouth to the stomach), stomach and intestines: anytime during use without warning symptoms that may cause death The risk of getting an ulcer or bleeding increases with: past history of stomach ulcers, or stomach or intestinal bleeding with use of NSAIDs taking medicines called \"corticosteroids\", \"anticoagulants\", \"SSRIs\", or \"SNRIs\" increasing doses of NSAIDs longer use of NSAIDs smoking drinking alcohol older age poor health advanced liver disease bleeding problems NSAIDs should only be used: exactly as prescribed at the lowest dose possible for your treatment for the shortest time needed What are NSAIDs? NSAIDs are used to treat pain and redness, swelling, and heat (inflammation) from medical conditions such as different types of arthritis, menstrual cramps, and other types of short-term pain. Who should not take NSAIDs? Do not take NSAIDs : if you have had an asthma attack, hives, or other allergic reaction with aspirin or any other NSAIDs. right before or after heart bypass surgery.

Only single doses of ketorolac tromethamine injection are recommended for use in pediatric patients. The most serious risks associated with ketorolac tromethamine are: Cardiovascular Thrombotic Events Clinical trials of several COX-2 selective and nonselective NSAIDs of up to three years duration have shown an increased risk of serious cardiovascular (CV) thrombotic events, including myocardial infarction (MI) and stroke, which can be fatal. Based on available data, it is unclear that the risk for CV thrombotic events is similar for all NSAIDs. The relative increase in serious CV thrombotic events over baseline conferred by NSAID use appears to be similar in those with and without known CV disease or risk factors for CV disease. However, patients with known CV disease or risk factors had a higher absolute incidence of excess serious CV thrombotic events, due to their increased baseline rate. Some observational studies found that this increased risk of serious CV thrombotic events began as early as the first weeks of treatment. The increase in CV thrombotic risk has been observed most consistently at higher doses. To minimize the potential risk for an adverse CV event in NSAID-treated patients, use the lowest effective dose for the shortest duration possible. Physicians and patients should remain alert for the development of such events, throughout the entire treatment course, even in the absence of previous CV symptoms. Patients should be informed about the symptoms of serious CV events and the steps to take if they occur. There is no consistent evidence that concurrent use of aspirin mitigates the increased risk of serious CV thrombotic events associated with NSAID use. The concurrent use of aspirin and an NSAID, such as [active moiety], increases the risk of serious gastrointestinal (GI) events (see WARNINGS ). Status Post Coronary Artery Bypass Graft (CABG) Surgery Two-large, controlled clinical trials of a COX-2 selective NSAID for the treatment of pain in the first 10 to 14 days following CABG surgery found an increased incidence of myocardial infarction and stroke. NSAIDs are contraindicated in the setting of CABG (see CONTRAINDICATIONS ). Post-MI Patients Observational studies conducted in the Danish National Registry have demonstrated that patients treated with NSAIDs in the post-MI period were at increased risk of reinfarction, CV-related death, and all-cause mortality beginning in the first week of treatment. In this same cohort, the incidence of death in the first-year post MI was 20 per 100 person years in NSAID-treated patients compared to 12 per 100 person years in non-NSAID exposed patients. Although the absolute rate of death declined somewhat after the first year post-MI, the increased relative risk of death in NSAID users persisted over at least the next four years of follow-up. Avoid the use of ketorolac tromethamine in patients with a recent MI unless the benefits are expected to outweigh the risk of recurrent CV thrombotic events. If ketorolac tromethamine is used in patients with a recent MI, monitor patients for signs of cardiac ischemia. Heart Failure and Edema The Coxib and traditional NSAID Trialists’ Collaboration meta-analysis of randomized controlled trials demonstrated an approximately two-fold increase in hospitalizations for heart failure in COX-2 selective-treated patients and nonselective NSAID-treated patients compared to placebo-treated patients. In a Danish National Registry study of patients with heart failure, NSAID use increased the risk of MI, hospitalization for heart failure, and death. Additionally, fluid retention and edema have been observed in some patients treated with NSAIDs. Use of [active moiety] may blunt the CV effects of several therapeutic agents used to treat these medical conditions [e.g., diuretics, ACE inhibitors, or angiotensin receptor blockers (ARBs)] (see Drug Interactions ). Avoid the use of ketorolac tromethamine in patients with severe heart failure unless the benefits are expected to outweigh the risk of worsening heart failure. If ketorolac tromethamine is used in patients with severe heart failure, monitor patients for signs of worsening heart failure. Gastrointestinal (GI) Effects Risk of Gastrointestinal Ulcerations, Bleeding and Perforation Ketorolac tromethamine is CONTRAINDICATED in patients with previously documented peptic ulcers and/or GI bleeding. Serious gastrointestinal toxicity, such as bleeding, ulceration and perforation, can occur at any time, with or without warning symptoms, in patients treated with ketorolac tromethamine. Studies to date with NSAIDs have not identified any subset of patients not at risk of developing peptic ulceration and bleeding. Elderly or debilitated patients seem to tolerate ulceration or bleeding less well than other individuals, and most spontaneous reports of fatal GI events are in this population. Postmarketing experience with parenterally administered ketorolac tromethamine suggests that there may be a greater risk of gastrointestinal ulcerations, bleeding and perforation in the elderly. The incidence and severity of gastrointestinal complications increases with increasing dose of, and duration of treatment with, ketorolac tromethamine. In a non-randomized, in-hospital postmarketing surveillance study comparing parenteral ketorolac tromethamine to parenteral opioids, higher rates of clinically serious GI bleeding were seen in patients <65 years of age who received an average total daily dose of more than 90 mg of ketorolac tromethamine injection, USP per day (see CLINICAL PHARMACOLOGY , Postmarketing Surveillance Study ). The same study showed that elderly (≥65 years of age) and debilitated patients are more susceptible to gastrointestinal complications. A history of peptic ulcer disease was revealed as another risk factor that increases the possibility of developing serious gastrointestinal complications during ketorolac tromethamine therapy (see Tables 3A and 3B ). Impaired Renal Function Ketorolac tromethamine should be used with caution in patients with impaired renal function or a history of kidney disease because it is a potent inhibitor of prostaglandin synthesis. Renal toxicity with ketorolac tromethamine has been seen in patients with conditions leading to a reduction in blood volume and/or renal blood flow where renal prostaglandins have a supportive role in the maintenance of renal perfusion. In these patients administration of ketorolac tromethamine may cause a dose-dependent reduction in renal prostaglandin formation and may precipitate acute renal failure. Patients at greatest risk of this reaction are those with impaired renal function, dehydration, heart failure, liver dysfunction, those taking diuretics and the elderly. Discontinuation of ketorolac tromethamine therapy is usually followed by recovery to the pretreatment state. Renal Effects Ketorolac tromethamine and its metabolites are eliminated primarily by the kidneys, which, in patients with reduced creatinine clearance, will result in diminished clearance of the drug (see CLINICAL PHARMACOLOGY ). Therefore, ketorolac tromethamine should be used with caution in patients with impaired renal function (see DOSAGE AND ADMINISTRATION ) and such patients should be followed closely. With the use of ketorolac tromethamine, there have been reports of acute renal failure, nephritis and nephrotic syndrome. Because patients with underlying renal insufficiency are at increased risk of developing acute renal failure, the risks and benefits should be assessed prior to giving ketorolac tromethamine to these patients. Hence, in patients with moderately elevated serum creatinine, it is recommended that the daily dose of ketorolac tromethamine injection, USP be reduced by half, not to exceed 60 mg/day. KETOROLAC TROMETHAMINE is CONTRAINDICATED in patients with serum creatinine concentrations indicating advanced renal impairment (see CONTRAINDICATIONS ). Hypovolemia should be corrected before treatment with ketorolac tromethamine is initiated. Drug Rash with Eosinophilia and Systemic Symptoms (DRESS) Drug Reaction with Eosinophilia and Systemic Symptoms (DRESS) has been reported in patients taking NSAIDs such as ketorolac tromethamine. Some of these events have been fatal or life-threatening. DRESS typically, although not exclusively, presents with fever, rash, lymphadenopathy, and/or facial swelling. Other clinical manifestations may include hepatitis, nephritis, hematological abnormalities, myocarditis, or myositis. Sometimes symptoms of DRESS may resemble an acute viral infection. Eosinophilia is often present. Because this disorder is variable in its presentation, other organ systems not noted here may be involved.It is important to note that early manifestations of hypersensitivity, such as fever or lymphadenopathy, may be present even though rash is not evident. If such signs or symptoms are present, discontinue ketorolac tromethamine and evaluate the patient immediately. Fluid Retention and Edema Fluid retention, edema, retention of NaCl, oliguria, elevations of serum urea nitrogen and creatinine have been reported in clinical trials with ketorolac tromethamine. Therefore, ketorolac tromethamine should be used only very cautiously in patients with cardiac decompensation, hypertension or similar conditions. Fetal Toxicity Premature Closure of Fetal Ductus Arteriosus: Avoid use of NSAIDs, including ketorolac tromethamine , in pregnant women at about 30-weeks gestation and later. NSAIDs including ketorolac tromethamine, increase the risk of premature closure of the fetal ductus arteriosus at approximately this gestational age. Oligohydramnios/Neonatal Renal Impairment: Use of NSAIDs, including ketorolac tromethamine, at about 20 weeks gestation or later inpregnancy may cause fetal renal dysfunction leading to oligohydramnios and, in some cases, neonatal renal impairment. These adverse outcomes are seen, on average, after days to weeks of treatment, although oligohydramnios has been infrequently reported as soon as 48 hours after NSAID initiation. Oligohydramnios is often, but not always, reversible with treatment discontinuation. Complications of prolonged oligohydramnios may, for example,include limb contractures and delayed lung maturation. In some postmarketing cases of impaired neonatal renal function, invasive procedures such as exchange transfusion or dialysis were required. If NSAID treatment is necessary between about 20 weeks and 30 weeks gestation, limit ketorolac tromethamine use to the lowest effective dose and shortest duration possible. Consider ultrasound monitoring of amniotic fluid if ketorolac tromethamine treatment extends beyond 48 hours. Discontinue ketorolac tromethamine if oligohydramnios occurs and follow up according to clinical practice [see PRECAUTIONS ; Pregnancy]. Hemorrhage Because prostaglandins play an important role in hemostasis and NSAIDs affect platelet aggregation as well, use of ketorolac tromethamine in patients who have coagulation disorders should be undertaken very cautiously, and those patients should be carefully monitored. Patients on therapeutic doses of anticoagulants (eg, heparin or dicumarol derivatives) have an increased risk of bleeding complications if given ketorolac tromethamine concurrently; therefore, physicians should administer such concomitant therapy only extremely cautiously. The concurrent use of ketorolac tromethamine and prophylactic low-dose heparin (2500 to 5000 units q12h), warfarin and dextrans have not been studied extensively, but may also be associated with an increased risk of bleeding. Until data from such studies are available, physicians should carefully weigh the benefits against the risks and use such concomitant therapy in these patients only extremely cautiously. In patients who receive anticoagulants for any reason, there is an increased risk of intramuscular hematoma formation from administered ketorolac intramuscularly (see PRECAUTIONS , Drug Interactions ). Patients receiving therapy that affects hemostasis should be monitored closely. In postmarketing experience, postoperative hematomas and other signs of wound bleeding have been reported in association with the perioperative use of ketorolac tromethamine injection. Therefore, perioperative use of ketorolac tromethamine should be avoided and postoperative use be undertaken with caution when hemostasis is critical (see WARNINGS and PRECAUTIONS ). Pediatrics and Tonsillectomy Physicians should consider the increased risk of bleeding before deciding to administer ketorolac tromethamine in patients following tonsillectomy. Ketorolac tromethamine injection is not recommended for use in pediatric patients below the age of 2 years. In a retrospective analysis of patients having undergone tonsillectomy with or without adenoidectomy, the risk of bleeding was 10.1% in patients administered ketorolac tromethamine injection compared to 2.2% in those receiving opioids. The postoperative hemorrhage rate in patients 12 years and younger was 6.5% and 3.3% with and without ketorolac tromethamine injection, USP, respectively. In a prospective study of ketorolac tromethamine in pediatric patients (ages 3 to 9 years) undergoing tonsillectomy with or without adenoidectomy, the overall incidence of bleeding was similar between the patients receiving ketorolac tromethamine and morphine (16.3% versus 17%, respectively). However, during the first 24 hours after surgery, a higher incidence of bleeding was observed in the ketorolac tromethamine injection group (14.3%) versus the morphine group (4.2%). Anaphylactoid Reactions Anaphylactoid reactions may occur in patients without a known previous exposure or hypersensitivity to aspirin, ketorolac tromethamine or other NSAIDs, or in individuals with a history of angioedema, bronchospastic reactivity (e.g., asthma) and nasal polyps. Anaphylactoid reactions, like anaphylaxis, may have a fatal outcome."]}
