Drug Details [pdf]

  • 1 INDICATIONS AND USAGE

    Ceftriaxone for Injection and Dextrose Injection is indicated for the treatment of the following infections when caused by susceptible bacteria.

    1.1 Lower Respiratory Tract Infections

    Lower respiratory tract infections caused by Streptococcus pneumoniae, Staphylococcus aureus, Haemophilus influenzae, Haemophilus parainfluenzae, Klebsiella pneumoniae, Escherichia coli, Enterobacter aerogenes, Proteus mirabilis or Serratia marcescens.

    1.2 Skin and Skin Structure Infections

    Skin and skin structure infections caused by Staphylococcus aureus, Staphylococcus epidermidis, Streptococcus pyogenes, Viridans group streptococci, Escherichia coli, Enterobacter cloacae, Klebsiella oxytoca, Klebsiella pneumoniae, Proteus mirabilis, Morganella morganii1, Pseudomonas aeruginosa, Serratia marcescens, Acinetobacter calcoaceticus, Bacteroides fragilis1 or Peptostreptococcus species.

  • 1 The efficacy for these organisms in this organ system were studied in fewer than ten infections.

    • 1.3 Complicated and Uncomplicated Urinary Tract Infections

    Complicated and uncomplicated urinary tract infections caused by Escherichia coli, Proteus mirabilis, Proteus vulgaris, Morganella morganii or Klebsiella pneumoniae.

    1.4 Pelvic Inflammatory Disease

    Pelvic inflammatory disease caused by Neisseria gonorrhoeae. Ceftriaxone sodium, like other cephalosporins, has no activity against Chlamydia trachomatis. Therefore, when cephalosporins are used in the treatment of patients with pelvic inflammatory disease and Chlamydia trachomatis is one of the suspected pathogens, appropriate antichlamydial coverage should be added.

    1.5 Bacterial Septicemia

    Bacterial septicemia caused by Staphylococcus aureus, Streptococcus pneumoniae, Escherichia coli, Haemophilus influenzae or Klebsiella pneumoniae.

    1.6 Bone and Joint Infections

    Bone and joint infections caused by Staphylococcus aureus, Streptococcus pneumoniae, Escherichia coli, Proteus mirabilis, Klebsiella pneumoniae or Enterobacter species.

    1.7 Intra-abdominal Infections

    Intra-abdominal infections caused by Escherichia coli, Klebsiella pneumoniae, Bacteroides fragilis, Clostridium species or Peptostreptococcus species.

    1.8 Meningitis

    Meningitis caused by Haemophilus influenzae, Neisseria meningitidis or Streptococcus pneumoniae. Ceftriaxone sodium has also been used successfully in a limited number of cases of meningitis and shunt infection caused by Staphylococcus epidermidis and Escherichia coli, however, the efficacy for these organisms in this organ system were studied in fewer than ten infections.

    1.9 Surgical Prophylaxis

    The preoperative administration of a single 1 g dose of Ceftriaxone for Injection and Dextrose Injection may reduce the incidence of postoperative infections in patients undergoing surgical procedures classified as contaminated or potentially contaminated (e.g., vaginal or abdominal hysterectomy or cholecystectomy for chronic calculous cholecystitis in high-risk patients, such as those over 70 years of age, with acute cholecystitis not requiring therapeutic antimicrobials, obstructive jaundice or common duct bile stones) and in surgical patients for whom infection at the operative site would present serious risk (e.g., during coronary artery bypass surgery). Although ceftriaxone sodium has been shown to have been as effective as cefazolin in the prevention of infection following coronary artery bypass surgery, no placebo-controlled trials have been conducted to evaluate any cephalosporin antibacterial in the prevention of infection following coronary artery bypass surgery.

    1.10 Usage

    To reduce the development of drug-resistant bacteria and maintain the effectiveness of Ceftriaxone for Injection and Dextrose Injection and other antibacterial drugs, Ceftriaxone for Injection and Dextrose Injection should be used only to treat or prevent infections that are proven or strongly suspected to be caused by susceptible bacteria. When culture and susceptibility information are available, they should be considered in selecting or modifying antibacterial therapy. In the absence of such data, local epidemiology and susceptibility patterns may contribute to the empiric selection of therapy.

  • 2 DOSAGE AND ADMINISTRATION

    2.1 Adult Population

    Ceftriaxone for Injection and Dextrose Injection in the DUPLEX® Container should be used only in patients who require the entire 1 or 2 gram dose and not any fraction thereof. The recommended adult dosages are outlined in Table 1. Ceftriaxone for Injection and Dextrose Injection should be administered intravenously (IV) over approximately 30 minutes.         

    The usual duration of therapy is 4 to 14 days; in complicated infections, longer therapy may be required. When treating infections caused by Streptococcus pyogenes, therapy should be continued for at least 10 days.

    2.2 Pediatric Patients

    Ceftriaxone for Injection and Dextrose Injection in the DUPLEX® Container is designed to deliver a 1 g or 2 g dose of ceftriaxone. To prevent unintentional overdose, this product should not be used in pediatric patients who require less than the full adult dose of ceftriaxone. [see Use in Specific Populations (8.4)]

    2.3 Preparation for Use of Ceftriaxone for Injection and Dextrose Injection in DUPLEX® Container

    This reconstituted solution is for intravenous use only.

    Do not use plastic containers in series connections. Such use would result in air embolism due to residual air being drawn from the primary container before administration of the fluid from the secondary container is complete. If administration is controlled by a pumping device, care must be taken to discontinue pumping action before the container runs dry or air embolism may result.

    Parenteral drug products should be inspected visually for particulate matter and discoloration prior to administration. Use only if solution is clear and container and seals are intact.

    DUPLEX® Container Storage

    • To avoid inadvertent activation, the DUPLEX® Container should remain in the folded position until activation is intended.

    Patient Labeling and Drug Powder/Diluent Inspection

    • Apply patient-specific label on foil side of container. Use care to avoid activation. Do not cover any portion of foil strip with patient label.
    • Unlatch side tab and unfold DUPLEX® Container (see Diagram 1).
    Diagram 1
    • Visually inspect diluent chamber for particulate matter.
    • Use only if container and seals are intact.
    • To inspect the drug powder for foreign matter or discoloration, peel foil strip from drug chamber (see Diagram 2).
    Diagram 2
    • Protect from light after removal of foil strip.
      Note: If foil strip is removed, the container should be re-folded and the side tab latched until ready to activate. The product must then be used within 7 days, but not beyond the labeled expiration date.

    Reconstitution (Activation)

    • Do not use directly after storage by refrigeration, allow the product to equilibrate to room temperature before patient use.
    • Unfold the DUPLEX® container and point the set port in a downward direction. Starting at the hanger tab end, fold the DUPLEX® Container just below the diluent meniscus trapping all air above the fold. To activate, squeeze the folded diluent chamber until the seal between the diluent and powder opens, releasing diluent into the drug powder chamber (see Diagram 3).
    Diagram 3
    • Agitate the liquid-powder mixture until the drug powder is completely dissolved.
      Note: Following reconstitution (activation), product must be used within 24 hours if stored at room temperature or within 7 days if stored under refrigeration.

    Administration

    • Visually inspect the reconstituted solution for particulate matter.
    • Point the set port in a downwards direction. Starting at the hanger tab end, fold the DUPLEX® Container just below the solution meniscus trapping all air above the fold. Squeeze the folded DUPLEX® Container until the seal between reconstituted drug solution and set port opens, releasing liquid to set port (see Diagram 4).
    Diagram 4
    • Prior to attaching the IV set, check for minute leaks by squeezing container firmly. If leaks are found, discard container and solution as sterility may be compromised.
    • Using aseptic technique, peel foil cover from the set port and attach sterile administration set (see Diagram 5).
    Diagram 5
    • Refer to directions for use accompanying the administration set.

    Important Administration Instructions

    • Do not use in series connections.
    • Do not introduce additives into the DUPLEX® Container.
    • Administer Ceftriaxone for Injection and Dextrose Injection intravenously over approximately 30 minutes.
    • After the indicated stability time periods, unused portions of solutions should be discarded.
    • Vancomycin, amsacrine, aminoglycosides, and fluconazole are physically incompatible with ceftriaxone in admixtures. When any of these drugs are to be administered concomitantly with ceftriaxone by intermittent intravenous infusion, it is recommended that they be given sequentially, with thorough flushing of the intravenous lines (with 0.9% sodium chloride injection or 5% dextrose in water (D5W)) between the administrations.
    • Ceftriaxone for Injection and Dextrose Injection should not be physically mixed with or piggybacked into solutions containing other antimicrobial drugs due to possible incompatibility. [see Drug Interactions (7.1)]
    • Precipitation of ceftriaxone-calcium can also occur when Ceftriaxone for Injection and Dextrose Injection is mixed with calcium-containing solutions in the same IV administration line. Ceftriaxone for Injection and Dextrose Injection must not be administered simultaneously with calcium-containing IV solutions, including continuous calcium-containing infusions such as parenteral nutrition via a Y-site. However, in patients other than neonates, Ceftriaxone for Injection and Dextrose Injection and calcium-containing solutions may be administered sequentially of one another if the infusion lines are thoroughly flushed between infusions with a compatible fluid. [see Warnings and Precautions (5.2)]
    • There have been no reports of an interaction between ceftriaxone and oral calcium-containing products or interaction between intramuscular ceftriaxone and calcium-containing products (IV or oral).
  • 3 DOSAGE FORMS AND STRENGTHS

    Dual-chamber, single-use container:

    • 1 g ceftriaxone for injection and 50 mL of 3.74% dextrose injection
    • 2 g ceftriaxone for injection and 50 mL of 2.22 % dextrose injection
  • 4 CONTRAINDICATIONS

    4.1 Anaphylaxis to Ceftriaxone or the Cephalosporin Class of Antibacterials, Penicillins, or Other Beta-lactam Antibacterials

    Ceftriaxone for Injection and Dextrose Injection is contraindicated in patients who have a history of anaphylaxis to ceftriaxone or the cephalosporin class of antibacterials, penicillins, or other beta-lactam antibacterials [see Warnings and Precautions (5.1)].

  • 5 WARNINGS AND PRECAUTIONS

    5.1 Hypersensitivity Reactions to Ceftriaxone, Cephalosporins, Penicillins, or Other Drugs

    Serious, occasionally fatal, hypersensitivity (anaphylactic) reactions have been reported with ceftriaxone. Before therapy with Ceftriaxone for Injection and Dextrose Injection is instituted, careful inquiry should be made to determine whether the patient has had previous immediate hypersensitivity reactions to ceftriaxone, cephalosporins, penicillins, or other drugs. Exercise caution if this product is to be given to penicillin-sensitive patients because cross-hypersensitivity among beta-lactam antibacterials has been clearly documented and may occur in up to 10% of patients with a history of penicillin allergy. If an allergic reaction to Ceftriaxone for Injection and Dextrose Injection occurs, discontinue the drug. Serious acute hypersensitivity reactions may require treatment with epinephrine and other emergency measures including oxygen, corticosteroids, intravenous fluids, intravenous antihistamines, pressor amines, and airway management, as clinically indicated.

    5.2 Interaction with Calcium-containing Products

    Precipitation of ceftriaxone-calcium can occur when Ceftriaxone for Injection and Dextrose Injection is mixed with calcium-containing solutions in the same IV administration line. Ceftriaxone for Injection and Dextrose Injection must not be administered simultaneously with calcium-containing IV solutions, including continuous calcium-containing infusions such as parenteral nutrition via a Y-site. However, in patients other than neonates, Ceftriaxone for Injection and Dextrose Injection and calcium-containing solutions may be administered sequentially of one another if the infusion lines are thoroughly flushed between infusions with 0.9% sodium chloride injection or D5W. In vitro studies using adult and neonatal plasma from umbilical cord blood demonstrated that neonates have an increased risk of precipitation of ceftriaxone-calcium. [see Drug Interactions (7.2)]

    5.3 Clostridium difficile-associated Diarrhea

    Clostridium difficile-associated diarrhea (CDAD) has been reported with use of nearly all antibacterial agents, including ceftriaxone, and may range in severity from mild diarrhea to fatal colitis. Treatment with antibacterial agents alters the normal flora of the colon leading to overgrowth of C. difficile.

    C. difficile produces toxins A and B, which contribute to the development of CDAD. Hypertoxin-producing strains of C. difficile cause increased morbidity and mortality, as these infections can be refractory to antimicrobial therapy and may require colectomy. CDAD must be considered in all patients who present with diarrhea following antibacterial use. Careful medical history is necessary since CDAD has been reported to occur over two months after the administration of antibacterial agents.

    If CDAD is suspected or confirmed, ongoing antibacterial use not directed against C. difficile may need to be discontinued. Appropriate fluid and electrolyte management, protein supplementation, antibacterial treatment of C. difficile, and surgical evaluation should be instituted as clinically indicated.

    5.4 Hemolytic Anemia

    An immune mediated hemolytic anemia has been observed in patients receiving cephalosporin class antibacterials including ceftriaxone. Severe cases of hemolytic anemia, including fatalities, have been reported during treatment in both adults and children. If a patient develops anemia while on Ceftriaxone for Injection and Dextrose Injection, the diagnosis of a cephalosporin associated anemia should be considered and Ceftriaxone for Injection and Dextrose Injection stopped until the etiology is determined.

    5.5 Hypersensitivity to Dextrose Products

    Hypersensitivity reactions, including anaphylaxis, have been reported with administration of dextrose products. These reactions have been reported in patients receiving high concentrations of dextrose (i.e. 50% dextrose)1. The reactions have also been reported when corn-derived dextrose solutions were administered to patients with or without a history of hypersensitivity to corn products2.

    5.6 Gallbladder Pseudolithiasis

    Ceftriaxone-calcium precipitates in the gallbladder have been observed in patients receiving ceftriaxone. These precipitates appear on sonography as an echo without acoustical shadowing suggesting sludge or as an echo with acoustical shadowing which may be misinterpreted as gallstones. The probability of such precipitates appears to be greatest in pediatric patients. Patients may be asymptomatic or may develop symptoms of gallbladder disease. The condition appears to be reversible upon discontinuation of ceftriaxone and institution of conservative management. Discontinue ceftriaxone in patients who develop signs and symptoms suggestive of gallbladder disease and/or the sonographic findings described above.

    5.7 Urolithiasis and Post-Renal Acute Renal Failure

    Ceftriaxone-calcium precipitates in the urinary tract have been observed in patients receiving ceftriaxone and may be detected as sonographic abnormalities. The probability of such precipitates appears to be greatest in pediatric patients. Patients may be asymptomatic or may develop symptoms of urolithiasis, and ureteral obstruction and post-renal acute renal failure. The condition appears to be reversible upon discontinuation of ceftriaxone and institution of appropriate management. Ensure adequate hydration in patients receiving ceftriaxone. Discontinue ceftriaxone in patients who develop signs and symptoms suggestive of urolithiasis, oliguria or renal failure and/or the sonographic findings described above.

    5.8 Patients with Hepatic and Renal Impairment

    In patients with both hepatic impairment and significant renal disease, Ceftriaxone for Injection and Dextrose Injection dosage should not exceed 2 g daily.

    5.9 Pancreatitis

    Cases of pancreatitis, possibly secondary to biliary obstruction, have been reported in patients treated with ceftriaxone sodium. Most patients presented with risk factors for biliary stasis and biliary sludge (preceding major therapy, severe illness, total parenteral nutrition). A cofactor role of ceftriaxone-related biliary precipitation cannot be ruled out.

    5.10 Development of Drug-resistant Bacteria

    Prescribing Ceftriaxone for Injection and Dextrose Injection in the absence of a proven or strongly suspected bacterial infection or a prophylactic indication is unlikely to provide benefit to the patient and increases the risk of the development of drug-resistant bacteria. As with other antibacterial drugs, use of Ceftriaxone for Injection and Dextrose Injection may result in overgrowth of nonsusceptible organisms. Careful observation of the patient is essential. If superinfection occurs during therapy, appropriate measures should be taken.

    5.11 Patients with Overt or Known Subclinical Diabetes Mellitus or Carbohydrate Intolerance

    As with other dextrose-containing solutions, Ceftriaxone for Injection and Dextrose Injection should be prescribed with caution in patients with overt or known subclinical diabetes mellitus or carbohydrate intolerance for any reason.

    5.12 Alterations in Prothrombin Time

    Alterations in prothrombin times have occurred in patients treated with ceftriaxone sodium. Patients with impaired vitamin K synthesis or low vitamin K stores (e.g., chronic hepatic disease and malnutrition) may require monitoring of prothrombin time during Ceftriaxone for Injection and Dextrose Injection treatment. Vitamin K administration (10 mg weekly) may be necessary if the prothrombin time is prolonged before or during therapy.

  • 6 ADVERSE REACTIONS

    The following serious adverse reactions to ceftriaxone are described below and elsewhere in the labeling:

    6.1 Clinical Trials Experience

    Because clinical trials are conducted under widely varying conditions, adverse reaction rates observed in the clinical trials of a drug cannot be directly compared to rates in the clinical trials of another drug and may not reflect the rates observed in practice. The following reactions occurred in less than or equal to 6% of the patients:

    • Local reactions—pain, induration, tenderness, and phlebitis after IV administration.
    • Hypersensitivity—rash, pruritus, fever or chills.
    • Hematologic—eosinophilia, thrombocytosis, leucopenia, anemia, hemolytic anemia, neutropenia, lymphopenia, thrombocytopenia, and prolongation of the prothrombin time.
    • Gastrointestinal—diarrhea, nausea or vomiting, and dysgeusia. The onset of pseudomembranous colitis symptoms may occur during or after antibacterial treatment [see Warnings and Precautions (5.3)].
    • Hepatic—elevations of SGOT, SGPT, alkaline phosphatase, bilirubin.
    • Renal—elevations of the BUN, creatinine, and the presence of casts in the urine.
    • Central nervous system—headache or dizziness.
    • Genitourinary—moniliasis or vaginitis.
    • Miscellaneous—diaphoresis and flushing.
    • Ceftriaxone-calcium precipitates—Cases of fatal reactions with ceftriaxone-calcium precipitates in lung and kidneys in neonates have been described. In some cases the infusion lines and times of administration of ceftriaxone and calcium-containing solutions differed [see Warnings and Precautions (5.2) and Drug Interactions (7.2)].
    • Other observed adverse reactions—abdominal pain, agranulocytosis, allergic pneumonitis, anaphylaxis, basophilia, biliary lithiasis, bronchospasm, colitis, dyspepsia, epistaxis, flatulence, gallbladder sludge, glycosuria, hematuria, jaundice, leukocytosis, lymphocytosis, monocytosis, nephrolithiasis, palpitations, a decrease in the prothrombin time, renal precipitations, seizures, and serum sickness.

    6.2 Postmarketing Experience

    The following adverse reactions have been reported during postapproval use of ceftriaxone. Because these reactions are reported voluntarily from a population of uncertain size, it is not always possible to readily estimate their frequency or establish a causal relationship to drug exposure.

    • Gastrointestinal—stomatitis and glossitis.
    • Genitourinary—oliguria, ureteric obstruction, post-renal acute renal failure
    • Hepatic—hepatitis. 
    • Dermatologic— severe cutaneous adverse reactions (erythema multiforme, Stevens-Johnson syndrome or Lyell’s syndrome/toxic epidermal necrolysis), exanthema, allergic dermatitis, urticaria, and edema.
    • Immunologic – Anaphylaxis (anaphylactic shock, transient leucopenia, neutropenia, agranulocytosis and thrombocytopenia). 

    6.3 Cephalosporin-class Adverse Reactions

    In addition to the adverse reactions listed above that have been observed in patients treated with ceftriaxone, the following adverse reactions and altered laboratory tests have been reported for cephalosporin-class antibacterials:

    • Adverse Reactions:  Allergic reactions, drug fever, serum sickness-like reaction, renal dysfunction, toxic nephropathy, reversible hyperactivity, hypertonia, hepatic dysfunction including hepatitis, cholestasis, aplastic anemia, hemorrhage, and superinfection.
    • Altered Laboratory Tests:  Positive direct Coombs’ test, false-positive test for urinary glucose, and elevated lactic acid dehydrogenase (LDH).
  • 7 DRUG INTERACTIONS

    7.1 Vancomycin, Amsacrine, Aminoglycosides, and Fluconazole

    Vancomycin, amsacrine, aminoglycosides, and fluconazole are physically incompatible with ceftriaxone in admixtures. [see Dosage and Administration (2.3)]

    7.2 Calcium-containing Products

    Precipitation of ceftriaxone-calcium can occur when Ceftriaxone for Injection and Dextrose Injection is mixed with calcium-containing solutions in the same IV administration line. Ceftriaxone for Injection and Dextrose Injection must not be administered simultaneously with calcium-containing IV solutions. Ceftriaxone for Injection and Dextrose Injection and calcium-containing solutions may be administered sequentially. [see Warnings and Precautions (5.2)]

  • 8 USE IN SPECIFIC POPULATIONS

    8.1 Pregnancy

    Pregnancy Category B

    Reproductive studies have been performed in mice, rats, and primates at intravenous doses of 625, 586, and 84 mg/kg/day respectively without evidence of embryotoxicity, fetotoxicity, or teratogenicity. These doses are approximately 1.5, 2.8, and 0.8 times the recommended clinical dose of 2 g/day based on body surface area comparisons.

    There are, however, no adequate and well-controlled studies in pregnant women. Because animal reproductive studies are not always predictive of human response, this drug should be used during pregnancy only if clearly needed.

    Ceftriaxone was tested in a Segment III (pre-postnatal) study in rats at intravenous doses of up to 586 mg/kg/day approximately 2.8 times (mg/m2 comparison) the recommended daily dose of 2 g/day. No adverse effects were noted on various reproductive parameters during gestation and lactation, including postnatal growth, functional behavior, and reproductive ability of the offspring.

    8.3 Nursing Mothers

    Ceftriaxone is excreted in human breast milk. Caution should be exercised when Ceftriaxone for Injection and Dextrose Injection is administered to a nursing woman.

    8.4 Pediatric Use

    Ceftriaxone for Injection and Dextrose Injection in the DUPLEX® Container is designed to deliver a 1 g or 2 g dose of ceftriaxone. To prevent unintentional overdose, this product should not be used in pediatric patients who require less than the full 1 g or 2 g adult dose of ceftriaxone.

    8.5 Geriatric Use

    Of the total number of subjects in clinical studies of ceftriaxone sodium, 32% were 60 and over. No overall differences in safety or effectiveness were observed between these subjects and younger subjects, and other reported clinical experience has not identified differences in responses between the elderly and younger patients, but greater sensitivity of some older individuals cannot be ruled out.

    Ceftriaxone is known to be substantially excreted by the kidney, and the risk of adverse reactions to this drug may be greater in patients with impaired renal function. Because elderly patients are more likely to have decreased renal function, care should be taken in dose selection, and it may be useful to monitor renal function.

    The pharmacokinetics of ceftriaxone were only minimally altered in geriatric patients compared to healthy adult subjects and dosage adjustments are not necessary for geriatric patients with ceftriaxone dosages up to 2 grams per day, provided there is no severe renal and hepatic impairment. [see Clinical Pharmacology (12)]

  • 10 OVERDOSAGE

    In the case of overdosage, drug concentration would not be reduced by hemodialysis or peritoneal dialysis. There is no specific antidote. Treatment of overdosage should be symptomatic.

  • 11 DESCRIPTION

The safety of the container system is supported by USP biological evaluation procedures.

  • 12 CLINICAL PHARMACOLOGY

    12.1 Mechanism of Action

    Ceftriaxone is an antibacterial drug [see Microbiology (12.4)].

    12.3 Pharmacokinetics

    Average plasma concentrations of ceftriaxone following a single 30-minute intravenous (IV) infusion of a 0.5, 1 or 2 g dose in healthy subjects are presented in Table 2. Multiple IV doses ranging from 0.5 to 2 g at 12- to 24-hour intervals resulted in 15% to 36% accumulation of ceftriaxone above single dose values.

    TABLE 2:  Ceftriaxone Plasma Concentrations After Single Dose Administration

  • * IV doses were infused at a constant rate over 30 minutes.
    		•

     2 g IV*  257 192 154 117 89 74 46 31 15

    Over a 0.15 to 3 g dose range in healthy adult subjects, the mean elimination half-life ranged from 5.8 to 8.7 hours, plasma clearance ranged from 0.58 to 1.45 L/hour, and renal clearance ranged from 0.32 to 0.73 L/hour.

    Distribution

    Ceftriaxone is reversibly bound to human plasma proteins and the binding of ceftriaxone decreases with increasing concentration from a value of 95% at plasma concentrations less than 25 mcg/mL to 85% at plasma concentration of 300 mcg/mL. Over a 0.15 to 3 g dose range in healthy adult subjects, the apparent volume of distribution ranged from 5.8 to 13.5 L.

    Ceftriaxone crosses the blood placenta barrier.

    Ceftriaxone penetrates the inflamed meninges of infants and pediatric patients. The average values of maximum plasma concentration, cerebrospinal fluid (CSF) concentrations, elimination half-life, plasma clearance and volume of distribution after a 50 mg/kg IV dose and after a 75 mg/kg IV dose in pediatric patients suffering from bacterial meningitis are shown in Table 3.

    After a 1 g IV dose, average concentrations of ceftriaxone, determined from 1 to 3 hours after dosing, were 581 mcg/mL in the gallbladder bile, 788 mcg/mL in the common duct bile, 898 mcg/mL in the cystic duct bile, and 78.2 mcg/g in the gallbladder wall compared to a corresponding concentration of 62.1 mcg/mL in plasma.

    Excretion

    Ceftriaxone concentrations in urine are shown in Table 4.

    Thirty-three percent to 67% of a ceftriaxone dose was excreted in the urine as unchanged drug and the remainder was secreted in the bile and ultimately found in the feces as microbiologically inactive compounds.

    The elimination of ceftriaxone is not altered by probenecid.

    Special Populations

    Average pharmacokinetic parameters of ceftriaxone in healthy subjects, elderly subjects, subjects with renal impairment, and subjects with liver disease are summarized in Table 5. Compared to healthy adult subjects, the pharmacokinetics of ceftriaxone were only minimally altered in elderly subjects and in patients with renal or hepatic impairment; therefore, dosage adjustments are not necessary for these patients with ceftriaxone dosages up to 2 g per day. Ceftriaxone was not removed to any significant extent from the plasma by hemodialysis. In 6 of 26 dialysis patients, the elimination rate of ceftriaxone was markedly reduced, suggesting that plasma concentrations of ceftriaxone should be monitored in these patients to determine if dosage adjustments are necessary. [see Dosage and Administration (2.1) and Warnings and Precautions (5.6)]

    Drug Interactions

    Interaction with Calcium: Two in vitro studies, one using adult plasma and the other neonatal plasma from umbilical cord blood have been carried out to assess interaction of ceftriaxone and calcium. Ceftriaxone concentrations up to 1 mM (in excess of concentrations achieved in vivo following administration of 2 grams ceftriaxone infused over 30 minutes) were used in combination with calcium concentrations up to 12 mM (48 mg/dL). Recovery of ceftriaxone from plasma was reduced with calcium concentrations of 6 mM (24 mg/dL) or higher in adult plasma or 4 mM (16 mg/dL) or higher in neonatal plasma. This may be reflective of ceftriaxone-calcium precipitation.

    12.4 Microbiology

    Mechanism of Action

    Ceftriaxone is a bactericidal agent that acts by inhibition of bacterial cell wall synthesis. Ceftriaxone has activity in the presence of some beta-lactamases, both penicillinases and cephalosporinases, of Gram-negative and Gram-positive bacteria.

    Mechanism of Resistance

    Resistance to ceftriaxone is primarily through hydrolysis by beta-lactamase, alteration of penicillin-binding proteins (PBPs), and decreased permeability.

    Interaction with Other Antimicrobials
    In an in vitro study antagonistic effects have been observed with the combination of chloramphenicol and ceftriaxone.

    Ceftriaxone has been shown to be active against most isolates of the following bacteria, both in vitro and in clinical infections [see Indications and Usage (1)]:

    • Gram-negative bacteria
      • Acinetobacter calcoaceticus
      • Enterobacter aerogenes
      • Enterobacter cloacae
      • Escherichia coli
      • Haemophilus influenzae
      • Haemophilus parainfluenzae
      • Klebsiella oxytoca
      • Klebsiella pneumoniae
      • Moraxella catarrhalis
      • Morganella morganii
      • Neisseria gonorrhoeae
      • Neisseria meningitidis
      • Proteus mirabilis
      • Proteus vulgaris
      • Pseudomonas aeruginosa
      • Serratia marcescens
    • Gram-positive bacteria
      • Staphylococcus aureus
      • Staphylococcus epidermidis  
      • Streptococcus pneumoniae
      • Streptococcus pyogenes
      • Viridans group streptococci
    • Anaerobic bacteria
      • Bacteroides fragilis
      • Clostridium species
      • Peptostreptococcus species

    The following in vitro data are available, but their clinical significance is unknown. At least 90 percent of the following microorganisms exhibit an in vitro minimum inhibitory concentration (MIC) less than or equal to the susceptible breakpoint for ceftriaxone. However, the efficacy of ceftriaxone in treating clinical infections due to these microorganisms has not been established in adequate and well-controlled clinical trials.

    • Gram-negative bacteria
      • Citrobacter diversus
      • Citrobacter freundii
      • Providencia species (including Providencia rettgeri)
      • Salmonella species (including Salmonella typhi)
      • Shigella species
    • Gram-positive bacteria
      • Streptococcus agalactiae
    • Anaerobic bacteria
      • Porphyromonas (Bacteroides) melaninogenicus
      • Prevotella (Bacteroides) bivius

  • 13 NONCLINICAL TOXICOLOGY

    13.1 Carcinogenesis, Mutagenesis, Impairment of Fertility

    Carcinogenesis

    Considering the maximum duration of treatment and the class of the compound, carcinogenicity studies with ceftriaxone in animals have not been performed. The maximum duration of animal toxicity studies was 6 months.

    Mutagenesis

    Genetic toxicology tests included the Ames test, a micronucleus test and a test for chromosomal aberrations in human lymphocytes cultured in vitro with ceftriaxone. Ceftriaxone showed no potential for genotoxic activity in these studies.

    Impairment of Fertility

    Ceftriaxone produced no impairment of fertility when given intravenously to rats at daily doses up to 586 mg/kg/day, approximately 2.8 times (mg/m2 comparison) the recommended clinical dose of 2 g/day.

    13.2 Animal Toxicology and/or Animal Pharmacology

    Concretions consisting of the precipitated calcium salt of ceftriaxone have been found in the gallbladder bile of dogs and baboons treated with ceftriaxone.

    These appeared as a gritty sediment in dogs that received 100 mg/kg/day for 4 weeks.

    A similar phenomenon has been observed in baboons but only after a protracted dosing period (6 months) at higher dose levels (335 mg/kg/day or more).

  • 16 HOW SUPPLIED/STORAGE AND HANDLING

    Ceftriaxone for Injection and Dextrose Injection in the DUPLEX® Container is a flexible dual chamber container supplied in two concentrations. After reconstitution, the concentrations are equivalent to 1 g and 2 g ceftriaxone. The diluent chamber contains approximately 50 mL of Dextrose Injection. Dextrose Injection has been adjusted to 3.74% and 2.22% for the 1 g and 2 g doses, respectively, such that the reconstituted solution is iso-osmotic.

    Ceftriaxone for Injection and Dextrose Injection is supplied sterile and nonpyrogenic in the DUPLEX® Container packaged 24 units per case.

     NDC  REFDose  Volume
     0264-3153-11 3153-11 1 g 50 mL
     0264-3155-11 3155-11 2 g 50 mL

    Store the unactivated unit at 20-25°C (68-77°F). Excursions permitted to 15 - 30°C (59-86°F). Do not freeze.

    Precautions

    As with other cephalosporins, reconstituted Ceftriaxone for Injection and Dextrose Injection tends to darken depending on storage conditions, within the stated recommendations. However, product potency is not adversely affected.

    Use only if prepared solution is clear and free from particulate matter.

    Do not use in series connection.

    Do not introduce additives into the DUPLEX® container.

  • 17 PATIENT COUNSELING INFORMATION

    Patients should be advised that allergic reactions, including serious allergic reactions could occur and that serious reactions require immediate treatment and discontinuation of ceftriaxone. Patients should report to their health care provider any previous allergic reactions to ceftriaxone, cephalosporins, penicillins, or other similar antibacterials.

    Advise patients of neurological adverse reactions that could occur with Ceftriaxone for Injection and Dextrose Injection use. Instruct patients to inform a healthcare provider at once of any neurological signs and symptoms, including encephalopathy (disturbance of consciousness including confusion, hallucinations, stupor, and coma), myoclonus, and seizures, for immediate treatment, dosage adjustment, or discontinuation of Ceftriaxone for Injection and Dextrose Injection.

    Patients should be advised that diarrhea is a common problem caused by antibacterials, which usually ends when the antibacterial is discontinued. Sometimes after starting treatment with antibacterials, patients can develop watery and bloody stools (with or without stomach cramps and fever) even as late as two or more months after having taken the last dose of the antibacterial. If this occurs, patients should contact a physician as soon as possible.

    Patients should be counseled that antibacterial drugs, including Ceftriaxone for Injection and Dextrose Injection should only be used to treat bacterial infections. They do not treat viral infections (e.g., the common cold). When Ceftriaxone for Injection and Dextrose Injection is prescribed to treat a bacterial infection, patients should be told that although it is common to feel better early in the course of therapy, the medication should be taken exactly as directed. Skipping doses or not completing the full course of therapy may (1) decrease the effectiveness of the immediate treatment and (2) increase the likelihood that bacteria will develop resistance and will not be treatable by Ceftriaxone for Injection and Dextrose Injection or other antibacterial drugs in the future.
