( 6.1 ) To report SUSPECTED ADVERSE REACTIONS, contact Mylan Pharmaceuticals Inc. at 1-877-446-3679 (1-877-4-INFO-RX) or FDA at 1-800-FDA-1088 or www.fda.gov/medwatch. 6.1 Clinical Trials Experience Because clinical trials are conducted under widely varying designs, the adverse reaction rates reported in one clinical trial may not be easily compared to those rates reported in another clinical trial, and may not reflect the rates actually observed in clinical practice. Repaglinide tablets have been administered to 2931 individuals during clinical trials. Approximately 1500 of these individuals with type 2 diabetes have been treated for at least 3 months, 1000 for at least 6 months, and 800 for at least 1 year. The majority of these individuals (1228) received repaglinide tablets in one of five 1-year, active-controlled trials. Over one year, 13% of repaglinide tablets patients were discontinued due to adverse reactions. The most common adverse reactions leading to withdrawal were hyperglycemia, hypoglycemia, and related symptoms . Table 1 lists the common adverse reactions for repaglinide tablets patients compared to placebo in trials 12 to 24 weeks duration.

Mild or moderate hypoglycemia occurred in 31% of repaglinide tablets treated patients and 7% of placebo treated patients [see Warnings and Precautions (5.1) ]. Hypoglycemia was reported in 16% of 1228 repaglinide tablets patients, 20% of 417 glyburide patients, and 19% of 81 glipizide patients in 1-year controlled trials. Of repaglinide tablets-treated patients with symptomatic hypoglycemia, none developed coma or required hospitalization. In a 24-week placebo controlled trial, patients who were naïve to oral hypoglycemic agent therapy and patients with a HbA 1c below 8% at baseline had a higher frequency of hypoglycemia. Weight Gain There was no average gain in body weight when patients previously treated with oral hypoglycemic agents were switched to repaglinide tablets. The average weight gain in patients treated with repaglinide tablets and not previously treated with sulfonylurea drugs was 3.3%. Cardiovascular Events The incidence of total serious cardiovascular adverse events, including ischemia, was higher for repaglinide tablets (51/1228 or 4%) than for sulfonylurea drugs (13/498 or 3%) in controlled comparator clinical trials.

There were six serious adverse events of myocardial ischemia in patients treated with repaglinide tablets plus NPH-insulin from two studies, and one event in patients using insulin formulations alone from another study [see Warnings and Precautions (5.3) ]. Combination Therapy with Thiazolidinediones Hypoglycemia During 24-week treatment clinical trials of repaglinide tablets-rosiglitazone or repaglinide tablets-pioglitazone combination therapy (a total of 250 patients in combination therapy), hypoglycemia (blood glucose < 50 mg/dL) occurred in 7% of patients in combination therapy compared to 7% for repaglinide tablets monotherapy, and 2% for thiazolidinedione monotherapy. Peripheral Edema and Heart Failure Peripheral edema was reported in 12 out of 250 (4.8%) repaglinide tablets-thiazolidinedione combination therapy patients and 3 out of 124 (2.4%) thiazolidinedione monotherapy patients, with no cases reported in these trials for repaglinide tablets monotherapy. There were reports in 2 of 250 patients (0.8%) treated with repaglinide tablets-thiazolidinedione therapy of episodes of edema with congestive heart failure. Both patients had a prior history of coronary artery disease and recovered after treatment with diuretic agents. No comparable cases in the monotherapy treatment groups were reported. Weight Gain Mean weight increases associated with combination, repaglinide tablets and pioglitazone therapy were 5.5 kg, 0.3 kg, and 2.0 kg respectively. Mean weight increases associated with combination, repaglinide tablets and rosiglitazone therapy were 4.5 kg, 1.3 kg, and 3.3 kg respectively. Infrequent Adverse Events (< 1% of Patients) Less common adverse clinical or laboratory events observed in clinical trials included elevated liver enzymes, thrombocytopenia, leukopenia, and anaphylactoid reactions. 6.2 Postmarketing Experience The following additional adverse reactions have been identified during post approval use of repaglinide tablets. Because these reactions are reported voluntarily from a population of uncertain size, it is generally not possible to reliably estimate their frequency or a causal relationship to drug exposure.

No evidence of carcinogenicity was found in female rats. The higher incidences of thyroid and liver tumors in male rats were not seen at lower dose of 30 mg/kg/day and 60 mg/kg/day respectively (which are over 15 and 30 times, respectively, clinical exposures on a mg/m 2 basis). In a 104-week carcinogenicity study in mice at doses up to 500 mg/kg/day, no evidence of carcinogenicity was found in mice (which is approximately 125 times clinical exposure on a mg/m 2 basis). Repaglinide was non-genotoxic in a battery of in vivo and in vitro studies: Bacterial mutagenesis (Ames test), in vitro forward cell mutation assay in V79 cells (HGPRT), in vitro chromosomal aberration assay in human lymphocytes, unscheduled and replicating DNA synthesis in rat liver, and in vivo mouse and rat micronucleus tests. In a rat fertility study, repaglinide was administered to male and female rats at doses up to 300 mg/kg/day and 80 mg/kg/day, respectively. No adverse effects on fertility were observed (which are over 40 times clinical exposure on a mg/m 2 basis)."],"clinical_pharmacology":["12 CLINICAL PHARMACOLOGY 12.1 Mechanism of Action Repaglinide lowers blood glucose levels by stimulating the release of insulin from the pancreas. This action is dependent upon functioning beta (ß) cells in the pancreatic islets. Insulin release is glucose-dependent and diminishes at low glucose concentrations. Repaglinide closes ATP-dependent potassium channels in the ß-cell membrane by binding at characterizable sites. This potassium channel blockade depolarizes the ß-cell, which leads to an opening of calcium channels. The resulting increased calcium influx induces insulin secretion. The ion channel mechanism is highly tissue selective with low affinity for heart and skeletal muscle. 12.2 Pharmacodynamics A four-week, double-blind, placebo-controlled dose-response trial was conducted in 138 patients with type 2 diabetes using doses ranging from 0.25 mg (not an approved dose) to 4 mg taken with each of three meals. Repaglinide tablets therapy resulted in dose-proportional glucose lowering over the full dose range. Plasma insulin levels increased after meals and reverted toward baseline before the next meal. Most of the fasting blood glucose-lowering effect was demonstrated within 1 to 2 weeks. In a double-blind, placebo-controlled, 3-month dose titration study, repaglinide tablets or placebo doses for each patient were increased weekly from 0.25 mg (not an approved dose) through 0.5 mg, 1 mg, and 2 mg, to a maximum of 4 mg, until a fasting plasma glucose (FPG) level < 160 mg/dL was achieved or the maximum dose reached. The dose that achieved the targeted control or the maximum dose was continued to end of study. FPG and 2-hour post-prandial glucose (PPG) increased in patients receiving placebo and decreased in patients treated with repaglinide. Differences between the repaglinide- and placebo-treated groups were -61 mg/dL (FPG) and -104 mg/dL (PPG) (Table 4). Table 4: Repaglinide Tablets vs Placebo Mean Change from Baseline after 3 Months of Treatment Repaglinide Placebo N 66 33 Fasting Plasma Glucose (mg/dL) Baseline 220.2 215.3 Change from baseline (at last visit) -31.0 p < 0.05 for between group difference 30.3 Post Prandial Glucose (mg/ dL) Baseline 261.7 245.2 Change from baseline (at last visit) -47.6 56.5 The dosing of repaglinide tablets relative to meal-related insulin release was studied in three trials including 58 patients. Glycemic control was maintained during a period in which the meal and dosing pattern was varied (2, 3 or 4 meals per day; before meals x 2, 3, or 4) compared with a period of 3 regular meals and 3 doses per day (before meals x 3). Blood glucose-lowering effect did not differ when repaglinide tablets were administered at the start of a meal, 15 minutes before, or 30 minutes before the meal. 12.3 Pharmacokinetics The pharmacokinetic parameters of repaglinide obtained from a single-dose, crossover study in healthy subjects and from a multiple-dose, parallel, dose-proportionality (0.5 mg, 1 mg, 2 mg and 4 mg) study in patients with type 2 diabetes are summarized in Tables 5 and 6. These data indicate that repaglinide did not accumulate in serum. Clearance of oral repaglinide did not change over the 0.5 mg to 4 mg dose range, indicating a linear relationship between dose and plasma drug levels. Table 5: Pharmacokinetic Parameters for Repaglinide in Healthy Subjects CL = total body clearance V ss = volume of distribution at steady state AbsBio = absolute bioavailability Parameter CL (based on i.v.) 38 L/hr ± 16 L/hr V ss (based on i.v.) 31 L ± 12 L AbsBio 56% ± 9% Table 6: Pharmacokinetic Parameters for Repaglinide in Patients with Type 2 Diabetes Dosed preprandially with three meals Pharmacokinetic Parameter Dose (mg) AUC 0-24 hr (ng/mL * hr) Mean (SD) C max 0-5 hr (ng/mL) Mean (SD) 0.5 68.9 (154.4) 9.8 (10.2) 1 125.8 (129.8) 18.3 (9.1) 2 152.4 (89.60) 26.0 (13.0) 4 447.4 (211.3) 65.8 (30.1) T max 0-5 hr Means (SD) T 1/2 Means (Ind Range) 0.5 - 4 1.0 to 1.4 (0.3 to 0.5) hr 1.0 to 1.4 (0.4 to 8.0) hr Absorption After oral administration, repaglinide is completely absorbed from the gastrointestinal tract. After single and multiple oral doses in healthy subjects or in patients, peak plasma drug levels (C max ) occur within 1 hour (T max ). Repaglinide is eliminated from the blood stream with a half-life of approximately 1 hour. The mean absolute bioavailability is 56%. When repaglinide was given with food, the mean T max was not changed, but the mean C max and AUC (area under the time/plasma concentration curve) were decreased 20% and 12.4%, respectively. Distribution After intravenous (IV) dosing in healthy subjects, the volume of distribution at steady state (V ss ) was 31 L, and the total body clearance (CL) was 38 L/h. Protein binding and binding to human serum albumin was greater than 98%. Metabolism and Elimination Repaglinide is completely metabolized by oxidative biotransformation and direct conjugation with glucuronic acid after either an IV or oral dose. The major metabolites are an oxidized dicarboxylic acid (M2), the aromatic amine (M1), and the acyl glucuronide (M7). The cytochrome P-450 enzyme system, specifically 2C8 and 3A4, have been shown to be involved in the N-dealkylation of repaglinide to M2 and the further oxidation to M1. Metabolites do not contribute to the glucose-lowering effect of repaglinide. Within 96 hours after dosing with 14 C-repaglinide as a single, oral dose, approximately 90% of the radiolabel was recovered in the feces and approximately 8% in the urine. Only 0.1% of the dose is cleared in the urine as parent compound. The major metabolite (M2) accounted for 60% of the administered dose. Less than 2% of parent drug was recovered in feces. Repaglinide appears to be a substrate for active hepatic uptake transporter (organic anion transporting protein OATP1B1). Variability of Exposure Repaglinide AUC after multiple doses of 0.25 mg to 4 mg with each meal varies over a wide range. The intra-individual and inter-individual coefficients of variation were 36% and 69%, respectively. AUC over the therapeutic dose range included 69 to 1005 ng/mL*hr, but AUC exposure up to 5417 ng/mL*hr was reached in dose escalation studies without apparent adverse consequences. Specific Populations Geriatric Healthy volunteers were treated with a regimen of 2 mg repaglinide tablets taken before each of 3 meals. There were no significant differences in repaglinide pharmacokinetics between the group of patients < 65 years of age and a comparably sized group of patients ≥ 65 years of age [see Use in Specific Populations (8.5) ]. Gender A comparison of pharmacokinetics in males and females showed the AUC over the 0.5 mg to 4 mg dose range to be 15% to 70% higher in females with type 2 diabetes. This difference was not reflected in the frequency of hypoglycemic episodes (male: 16%; female: 17%) or other adverse events. Race No pharmacokinetic studies to assess the effects of race have been performed, but in a U.S. 1-year study in patients with type 2 diabetes, the blood glucose-lowering effect was comparable between Caucasians (n = 297) and African-Americans (n = 33). In a U.S. dose-response study, there was no apparent difference in exposure (AUC) between Caucasians (n = 74) and Hispanics (n = 33). Renal Impairment Single-dose and steady-state pharmacokinetics of repaglinide were compared between patients with type 2 diabetes and normal renal function (CrCl > 80 mL/min), mild to moderate renal function impairment (CrCl = 40 mL/min to 80 mL/min), and severe renal function impairment (CrCl = 20 mL/min to 40 mL/min). Both AUC and C max of repaglinide were similar in patients with normal and mild to moderately impaired renal function (mean values 56.7 ng/mL*hr vs 57.2 ng/mL*hr and 37.5 ng/mL vs 37.7 ng/mL, respectively.) Patients with severely reduced renal function had elevated mean AUC and C max values (98.0 ng/mL*hr and 50.7 ng/mL, respectively), but this study showed only a weak correlation between repaglinide levels and creatinine clearance. Hepatic Impairment A single-dose, open-label study was conducted in 12 healthy subjects and 12 patients with chronic liver disease (CLD) classified by Child-Pugh scale and caffeine clearance. Patients with moderate to severe impairment of liver function had higher and more prolonged serum concentrations of both total and unbound repaglinide than healthy subjects (AUC healthy : 91.6 ng/mL*hr; AUC CLD patients : 368.9 ng/mL*hr; C max , healthy : 46.7 ng/mL; C max , CLD patients : 105.4 ng/mL). AUC was statistically correlated with caffeine clearance. No difference in glucose profiles was observed across patient groups. Drug-Drug Interactions Drug interaction studies performed in healthy volunteers show that repaglinide tablets had no clinically relevant effect on the pharmacokinetic properties of digoxin, theophylline, or warfarin. Co-administration of cimetidine with repaglinide tablets did not significantly alter the absorption and disposition of repaglinide. Additionally, the following drugs were studied in healthy volunteers with co-administration of repaglinide tablets.

"],"clinical_studies":["14 CLINICAL STUDIES 14.1 Monotherapy Trials A double-blind, placebo-controlled trial was carried out in 362 patients treated for 24 weeks. HbA 1c for the repaglinide tablets-treated groups (1 mg and 4 mg groups combined) at the end of the study was decreased compared to the placebo-treated group in treatment naïve patients and in patients previously treated with oral hypoglycemic agents by 2.1% and 1.7%, respectively. In this fixed-dose trial, patients who were treatment naïve to oral hypoglycemic agent therapy and patients with a HbA 1c below 8% at baseline showed greater blood glucose-lowering. 14.2 Combination Trials Repaglinide Tablets in Combination with Metformin Repaglinide tablets were studied in combination with metformin in 83 patients not satisfactorily controlled on exercise, diet, and metformin alone. Repaglinide tablets dosage was titrated for 4 to 8 weeks, followed by a 3-month maintenance period. Combination therapy with repaglinide tablets and metformin resulted in statistically significant improvement in HbA 1c and fasting plasma glucose (FPG) compared to repaglinide tablets or metformin monotherapy (Table 8). In this study where metformin dosage was kept constant, the combination therapy of repaglinide tablets and metformin showed dose-sparing effects with respect to repaglinide tablets. The improvement in HbA 1c and FPG of the combination group was achieved at a lower daily repaglinide tablets dosage than in the repaglinide tablets monotherapy group (Table 8).

Repaglinide tablets dosage was titrated during the first 12 weeks, followed by a 12-week maintenance period. Combination therapy resulted in statistically significant improvement in HbA 1c and FPG compared to monotherapy (Figure 1). The changes from baseline for completers in FPG (mg/dL) and HbA 1c (%), respectively were: -39.8 mg/dL and -0.1% for repaglinide tablets, -35.3 mg/dL and -0.1% for pioglitazone and -92.4 mg/dL and -1.9% for the combination. In this study where pioglitazone dosage was kept constant, the combination therapy group showed dose-sparing effects with respect to repaglinide tablets (see Figure 1 Legend). The improvement in HbA 1c and FPG of the combination group was achieved at a lower daily repaglinide tablets dosage than in the repaglinide tablets monotherapy group.

Combination therapy resulted in statistically significant improvement in HbA 1c and FPG compared to monotherapy (Table 9 below). The glycemic effects of the combination therapy were dose-sparing with respect to both total daily repaglinide tablets dosage and total daily rosiglitazone dosage (see Table 9 Legend).

This action is dependent upon functioning beta (ß) cells in the pancreatic islets. Insulin release is glucose-dependent and diminishes at low glucose concentrations. Repaglinide closes ATP-dependent potassium channels in the ß-cell membrane by binding at characterizable sites. This potassium channel blockade depolarizes the ß-cell, which leads to an opening of calcium channels. The resulting increased calcium influx induces insulin secretion. The ion channel mechanism is highly tissue selective with low affinity for heart and skeletal muscle."],"nonclinical_toxicology":["13 NONCLINICAL TOXICOLOGY 13.1 Carcinogenesis, Mutagenesis, Impairment of Fertility In a 104-week carcinogenicity study in rats at doses up to 120 mg/kg/day, which is approximately 60 times clinical exposure on a mg/m 2 basis, the incidences of benign adenomas of the thyroid and liver were increased in male rats. No evidence of carcinogenicity was found in female rats. The higher incidences of thyroid and liver tumors in male rats were not seen at lower dose of 30 mg/kg/day and 60 mg/kg/day respectively (which are over 15 and 30 times, respectively, clinical exposures on a mg/m 2 basis). In a 104-week carcinogenicity study in mice at doses up to 500 mg/kg/day, no evidence of carcinogenicity was found in mice (which is approximately 125 times clinical exposure on a mg/m 2 basis). Repaglinide was non-genotoxic in a battery of in vivo and in vitro studies: Bacterial mutagenesis (Ames test), in vitro forward cell mutation assay in V79 cells (HGPRT), in vitro chromosomal aberration assay in human lymphocytes, unscheduled and replicating DNA synthesis in rat liver, and in vivo mouse and rat micronucleus tests. In a rat fertility study, repaglinide was administered to male and female rats at doses up to 300 mg/kg/day and 80 mg/kg/day, respectively. No adverse effects on fertility were observed (which are over 40 times clinical exposure on a mg/m 2 basis)."],"nursing_mothers":["8.3 Nursing Mothers Although it is not known whether repaglinide is excreted in human milk some oral agents are known to be excreted by this route. Because the potential for hypoglycemia in nursing infants may exist, and because of the effects on nursing animals, a decision should be made as to whether repaglinide tablets should be discontinued in nursing mothers, or if mothers should discontinue nursing. If repaglinide tablets are discontinued and if diet alone is inadequate for controlling blood glucose, insulin therapy should be considered. In rat reproduction studies, measurable levels of repaglinide were detected in the breast milk of the dams and lowered blood glucose levels were observed in the pups. Cross fostering studies indicated that skeletal changes [see Use in Specific Populations (8.1) ] could be induced in control pups nursed by treated dams, although this occurred to a lesser degree than those pups treated in utero ."],"openfda":{},"overdosage":["10 OVERDOSAGE Severe hypoglycemic reactions with coma, seizure, or other neurological impairment may occur and constitute medical emergencies requiring immediate hospitalization.

These data indicate that repaglinide did not accumulate in serum. Clearance of oral repaglinide did not change over the 0.5 mg to 4 mg dose range, indicating a linear relationship between dose and plasma drug levels. Table 5: Pharmacokinetic Parameters for Repaglinide in Healthy Subjects CL = total body clearance V ss = volume of distribution at steady state AbsBio = absolute bioavailability Parameter CL (based on i.v.) 38 L/hr ± 16 L/hr V ss (based on i.v.) 31 L ± 12 L AbsBio 56% ± 9% Table 6: Pharmacokinetic Parameters for Repaglinide in Patients with Type 2 Diabetes Dosed preprandially with three meals Pharmacokinetic Parameter Dose (mg) AUC 0-24 hr (ng/mL * hr) Mean (SD) C max 0-5 hr (ng/mL) Mean (SD) 0.5 68.9 (154.4) 9.8 (10.2) 1 125.8 (129.8) 18.3 (9.1) 2 152.4 (89.60) 26.0 (13.0) 4 447.4 (211.3) 65.8 (30.1) T max 0-5 hr Means (SD) T 1/2 Means (Ind Range) 0.5 - 4 1.0 to 1.4 (0.3 to 0.5) hr 1.0 to 1.4 (0.4 to 8.0) hr Absorption After oral administration, repaglinide is completely absorbed from the gastrointestinal tract. After single and multiple oral doses in healthy subjects or in patients, peak plasma drug levels (C max ) occur within 1 hour (T max ). Repaglinide is eliminated from the blood stream with a half-life of approximately 1 hour. The mean absolute bioavailability is 56%. When repaglinide was given with food, the mean T max was not changed, but the mean C max and AUC (area under the time/plasma concentration curve) were decreased 20% and 12.4%, respectively. Distribution After intravenous (IV) dosing in healthy subjects, the volume of distribution at steady state (V ss ) was 31 L, and the total body clearance (CL) was 38 L/h. Protein binding and binding to human serum albumin was greater than 98%. Metabolism and Elimination Repaglinide is completely metabolized by oxidative biotransformation and direct conjugation with glucuronic acid after either an IV or oral dose. The major metabolites are an oxidized dicarboxylic acid (M2), the aromatic amine (M1), and the acyl glucuronide (M7). The cytochrome P-450 enzyme system, specifically 2C8 and 3A4, have been shown to be involved in the N-dealkylation of repaglinide to M2 and the further oxidation to M1. Metabolites do not contribute to the glucose-lowering effect of repaglinide. Within 96 hours after dosing with 14 C-repaglinide as a single, oral dose, approximately 90% of the radiolabel was recovered in the feces and approximately 8% in the urine. Only 0.1% of the dose is cleared in the urine as parent compound. The major metabolite (M2) accounted for 60% of the administered dose. Less than 2% of parent drug was recovered in feces. Repaglinide appears to be a substrate for active hepatic uptake transporter (organic anion transporting protein OATP1B1). Variability of Exposure Repaglinide AUC after multiple doses of 0.25 mg to 4 mg with each meal varies over a wide range. The intra-individual and inter-individual coefficients of variation were 36% and 69%, respectively. AUC over the therapeutic dose range included 69 to 1005 ng/mL*hr, but AUC exposure up to 5417 ng/mL*hr was reached in dose escalation studies without apparent adverse consequences. Specific Populations Geriatric Healthy volunteers were treated with a regimen of 2 mg repaglinide tablets taken before each of 3 meals. There were no significant differences in repaglinide pharmacokinetics between the group of patients < 65 years of age and a comparably sized group of patients ≥ 65 years of age [see Use in Specific Populations (8.5) ]. Gender A comparison of pharmacokinetics in males and females showed the AUC over the 0.5 mg to 4 mg dose range to be 15% to 70% higher in females with type 2 diabetes. This difference was not reflected in the frequency of hypoglycemic episodes (male: 16%; female: 17%) or other adverse events. Race No pharmacokinetic studies to assess the effects of race have been performed, but in a U.S. 1-year study in patients with type 2 diabetes, the blood glucose-lowering effect was comparable between Caucasians (n = 297) and African-Americans (n = 33). In a U.S. dose-response study, there was no apparent difference in exposure (AUC) between Caucasians (n = 74) and Hispanics (n = 33). Renal Impairment Single-dose and steady-state pharmacokinetics of repaglinide were compared between patients with type 2 diabetes and normal renal function (CrCl > 80 mL/min), mild to moderate renal function impairment (CrCl = 40 mL/min to 80 mL/min), and severe renal function impairment (CrCl = 20 mL/min to 40 mL/min). Both AUC and C max of repaglinide were similar in patients with normal and mild to moderately impaired renal function (mean values 56.7 ng/mL*hr vs 57.2 ng/mL*hr and 37.5 ng/mL vs 37.7 ng/mL, respectively.) Patients with severely reduced renal function had elevated mean AUC and C max values (98.0 ng/mL*hr and 50.7 ng/mL, respectively), but this study showed only a weak correlation between repaglinide levels and creatinine clearance. Hepatic Impairment A single-dose, open-label study was conducted in 12 healthy subjects and 12 patients with chronic liver disease (CLD) classified by Child-Pugh scale and caffeine clearance. Patients with moderate to severe impairment of liver function had higher and more prolonged serum concentrations of both total and unbound repaglinide than healthy subjects (AUC healthy : 91.6 ng/mL*hr; AUC CLD patients : 368.9 ng/mL*hr; C max , healthy : 46.7 ng/mL; C max , CLD patients : 105.4 ng/mL). AUC was statistically correlated with caffeine clearance. No difference in glucose profiles was observed across patient groups. Drug-Drug Interactions Drug interaction studies performed in healthy volunteers show that repaglinide tablets had no clinically relevant effect on the pharmacokinetic properties of digoxin, theophylline, or warfarin. Co-administration of cimetidine with repaglinide tablets did not significantly alter the absorption and disposition of repaglinide. Additionally, the following drugs were studied in healthy volunteers with co-administration of repaglinide tablets.

It is unknown whether repaglinide tablets can cause fetal harm when administered to a pregnant woman. Repaglinide tablets should be used during pregnancy only if the potential benefit justifies the potential risk to the fetus.

Relevant human exposure has not occurred to date and therefore the safety of repaglinide tablets administration throughout pregnancy or lactation cannot be established. 8.3 Nursing Mothers Although it is not known whether repaglinide is excreted in human milk some oral agents are known to be excreted by this route. Because the potential for hypoglycemia in nursing infants may exist, and because of the effects on nursing animals, a decision should be made as to whether repaglinide tablets should be discontinued in nursing mothers, or if mothers should discontinue nursing. If repaglinide tablets are discontinued and if diet alone is inadequate for controlling blood glucose, insulin therapy should be considered. In rat reproduction studies, measurable levels of repaglinide were detected in the breast milk of the dams and lowered blood glucose levels were observed in the pups. Cross fostering studies indicated that skeletal changes [see Use in Specific Populations (8.1) ] could be induced in control pups nursed by treated dams, although this occurred to a lesser degree than those pups treated in utero . 8.4 Pediatric Use Safety and effectiveness have not been established in pediatric patients. 8.5 Geriatric Use In clinical studies of 24 weeks or greater duration, 415 patients were over 65 years of age and no patients were greater than 75 years of age. In one-year, active-controlled trials, no differences were seen in effectiveness or adverse events between these subjects and those less than 65. There was no increase in frequency or severity of hypoglycemia in older subjects, but greater sensitivity of some older individuals to repaglinide tablets therapy cannot be ruled out. 8.6 Renal Impairment Pharmacokinetic studies of repaglinide were conducted in patients with mild to moderate renal function impairment (CrCl = 40 mL/min to 80 mL/min), and severe renal function impairment (CrCl = 20 mL/min to 40 mL/min). Initial dose adjustment is not required in patients with mild to moderate renal dysfunction. However, patients with severe renal function impairment should initiate repaglinide tablets therapy with the 0.5 mg dose and be carefully titrated [see Dosage and Administration (2.2) ]. Studies were not conducted in patients with creatinine clearances below 20 mL/min or patients with renal failure requiring hemodialysis. 8.7 Hepatic Impairment A single-dose study was conducted 12 patients with chronic liver disease. Patients with moderate to severe impairment of liver function had higher and more prolonged serum concentrations. Therefore, repaglinide tablets should be used cautiously in patients with impaired liver function. Longer intervals between dose adjustments may be needed to allow full assessment of response."],"version":"7","warnings_and_cautions":["5 WARNINGS AND PRECAUTIONS Hypoglycemia : Repaglinide tablets may cause hypoglycemia. Skip the scheduled dose of repaglinide tablets if a meal is skipped to reduce the risk of hypoglycemia. Reduce the dose of repaglinide tablets if hypoglycemia occurs. ( 5.1 ) Serious Cardiovascular Adverse Reactions with Concomitant NPH-insulin : Repaglinide tablets are not indicated for use in combination with NPH-insulin. ( 5.2 ) Macrovascular Outcomes : There have been no clinical studies establishing conclusive evidence of macrovascular risk reduction with repaglinide tablets. ( 5.3 ) 5.1 Hypoglycemia All glinides, including repaglinide tablets, can cause hypoglycemia [see Adverse Reactions (6.1) ] . Severe hypoglycemia can cause seizures, may be life-threatening, or cause death. Hypoglycemia can impair concentration ability and reaction time; this may place an individual and others at risk in situations where these abilities are important (e.g., driving or operating other machinery). Hypoglycemia can happen suddenly and symptoms may differ in each individual and change over time in the same individual. Symptomatic awareness of hypoglycemia may be less pronounced in patients with longstanding diabetes, in patients with diabetic nerve disease, in patients using medications that block the sympathetic nervous system (e.g., beta-blockers) [see Drug Interactions (7) ] , or in patients who experience recurrent hypoglycemia. Factors which may increase the risk of hypoglycemia include changes in meal pattern (e.g., macronutrient content), changes in level of physical activity, changes to co-administered medication [see Drug Interactions (7) ] , and concomitant use with other antidiabetic agents. Patients with renal or hepatic impairment may be at higher risk of hypoglycemia [see Use in Specific Populations (8.6 , 8.7) ]. Patients should administer repaglinide tablets before meals and be instructed to skip the dose of repaglinide tablets if a meal is skipped. In patients who experience hypoglycemia, the dose of repaglinide tablets should be reduced [see Dosage and Administration (2.1) ]. Patients and caregivers must be educated to recognize and manage hypoglycemia. Self-monitoring of blood glucose plays an essential role in the prevention and management of hypoglycemia. In patients at higher risk for hypoglycemia and patients who have reduced symptomatic awareness of hypoglycemia, increased frequency of blood glucose monitoring is recommended. 5.2 Serious Cardiovascular Adverse Reactions with Concomitant Use with NPH-insulin Across seven controlled trials, there were six serious adverse events of myocardial ischemia in patients treated with repaglinide tablets plus NPH-insulin from two studies, and one event in patients using insulin formulations alone from another study [see Adverse Reactions (6.1) ]. Repaglinide tablets are not indicated for use in combination with NPH-insulin. 5.3 Macrovascular Outcomes There have been no clinical studies establishing conclusive evidence of macrovascular risk reduction with repaglinide tablets."]}
