🩺 Clinical
Nateglinide is used alone or in combination with other medications to treat type 2 diabetes (condition in which the body does not use insulin normally and therefore cannot control the amount of sugar in the blood) in people whose diabetes cannot be controlled by diet and exercise alone. Nateglinide belongs to a class of drugs called meglitinides. Nateglinide helps your body regulate the amount of glucose (sugar) in your blood. It decreases the amount of glucose by stimulating the pancreas to release insulin. Over time, people who have diabetes and high blood sugar can develop serious or life-t...

⚠️ Warnings and Cautions ▾
5 WARNINGS AND PRECAUTIONS Hypoglycemia : Nateglinide may cause hypoglycemia. Administer before meals to reduce the risk of hypoglycemia. Skip the scheduled dose of nateglinide if a meal is skipped to reduce the risk of hypoglycemia. ( 5.1) Macrovascular Outcomes: There have been no clinical studies establishing conclusive evidence of macrovascular risk reduction with nateglinide. ( 5.2)
5.1Hypoglycemia All glinides, including nateglinide, 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 neuropathy (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 coadministered 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 ), Clinical Pharmacology (12.3 )]. Patients should take nateglinide before meals and be instructed to skip the dose of nateglinide if a meal is skipped [see Dosage and Administration (2) ]. 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.
5.2Macrovascular Outcomes There have been no clinical studies establishing conclusive evidence of macrovascular risk reduction with nateglinide.
🤒 Adverse Reactions ▾
6 ADVERSE REACTIONS The following serious adverse reaction is also described elsewhere in the labeling: Hypoglycemia [see Warnings and Precautions (5.1) ] Common adverse reactions associated with nateglinide (3% or greater incidence) were upper respiratory tract infection, back pain, flu symptoms, dizziness, arthropathy, diarrhea. (6.1) To report SUSPECTED ADVERSE REACTIONS, contact Dr. Reddy’s Laboratories Inc., at 1-888-375-3784 or FDA at 1-800-FDA-1088 or www.fda.gov/medwatch.
6.1Clinical 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. In clinical trials, approximately 2,600 patients with type 2 diabetes mellitus were treated with nateglinide. Of these, approximately 1,335 patients were treated for 6 months or longer and approximately 190 patients for one year or longer.
Table 1 shows the most common adverse reactions associated with nateglinide.

2.4Hypoglycemia Episodes of severe hypoglycemia (plasma glucose less than 36 mg/dL) were reported in two patients treated with nateglinide. Non-severe hypoglycemia occurred in 2.4 % of nateglinide treated patients and 0.4 % of placebo treated patients [see Warnings and Precautions ( 5.1) ]. Weight Gain Patients treated with nateglinide had statistically significant mean increases in weight compared to placebo.
In clinical trials, the mean weight increases with nateglinide 60 mg (3 times daily) and nateglinide 120 mg (3 times daily) compared to placebo were 1 kg and 1.6 kg respectively. Laboratory Test Increases in Uric Acid: There were increases in mean uric acid levels for patients treated with nateglinide alone, nateglinide in combination with metformin, metformin alone, and glyburide alone. The respective differences from placebo were 0.29 mg/dL, 0.45 mg/dL, 0.28 mg/dL, and 0.19 mg/dL.
6.2Postmarketing Experience The following adverse reactions have been identified during post-approval use of nateglinide. Because these reactions are reported voluntarily from a population of uncertain size, it is not always possible to reliably estimate their frequency or establish a causal relationship to drug exposure. Hypersensitivity Reactions: Rash, itching, and urticaria Hepatobiliary Disorders: Jaundice, cholestatic hepatitis, and elevated liver enzymes

👥 Use in Specific Populations ▾
8 USE IN SPECIFIC POPULATIONS Lactation: Nateglinide is not recommended when breastfeeding ( 8.2 )
8.1Pregnancy Risk Summary The available data from published literature and the applicant’s pharmacovigilance with use of nateglinide in pregnant women are insufficient to identify a drug-associated risk of major birth defects, miscarriage or other adverse maternal or fetal outcomes. There are risks to the mother and fetus associated with poorly controlled diabetes in pregnancy (see Clinical Considerations) . Nateglinide should be used during pregnancy only if the potential benefit justifies the potential risk to the fetus.
In animal reproduction studies, there was no teratogenicity in rats and rabbits administered oral nateglinide during organogenesis at approximately 27 and 8 times the maximum recommended human dose (MRHD), respectively, based on body surface area (BSA). The estimated background risk of major birth defects is 6% to 10% in women with pre-gestational diabetes with a HbA1c > 7 and has been reported to be as high as 20% to 25% in women with a HbA1c > 10. The estimated background risk of miscarriage for the indicated population is unknown.
In the U.S. general population, the estimated background risk of major birth defects and miscarriage in clinically recognized pregnancies is 2% to 4% and 15% to 20%, respectively. Clinical Considerations Disease-Associated Maternal and/or Embryo/Fetal Risk Poorly controlled diabetes in pregnancy increases the maternal risk for diabetic ketoacidosis, pre-eclampsia, spontaneous abortions, preterm delivery, and delivery complications. Poorly controlled diabetes increases the fetal risk for major birth defects, stillbirth, and macrosomia related morbidity.
Data Animal data In embryofetal development studies, nateglinide administered orally during the period of organogenesis was not teratogenic in rats at doses up to 1,000 mg/kg (corresponding to 27 times the MRHD of 120 mg three times per day, based on BSA). In rabbits, embryonic development was adversely affected at 500 mg/kg/day and the incidence of gallbladder agenesis or small gallbladder was increased at a dose of 300 and 500 mg/kg (corresponding to 16 and 27 times the MRHD). No such effects were observed at 150 mg/kg/day (corresponding to 8 times the MRHD).
In a pre-and postnatal development study in rats, nateglinide administered by oral gavage at doses of 100, 300, and 1000 mg/kg/day from gestation day 17 to lactation day 21 resulted in lower body weight in offspring of rats administered nateglinide at 1,000 mg/kg/day (corresponding to 27 times the MHRD).
8.2Lactation Risk summary There are no data on the presence of nateglinide in human milk, the effects on the breastfeeding infant, or the effects on milk production. The drug is present in animal milk. When a drug is present in animal milk, it is likely that the drug will be present in human milk (see Data).
Because the potential for hypoglycemia in breast-fed infants, advise women that use of nateglinide is not recommended while breastfeeding. Data In rat reproduction studies, nateglinide and its metabolite are excreted in the milk following oral dose (300 mg/kg). The overall milk: plasma (M/P) concentration ratio of the total radioactivity was approximately 1.4 based on AUC0-48 values.
The M/P ratio of unchanged nateglinide was approximately 2.2.
8.4Pediatric Use The safety and effectiveness of nateglinide have not been established in pediatric patients.
8.5Geriatric Use 436 patients 65 years and older, and 80 patients 75 years and older were exposed to nateglinide in clinical studies. No differences were observed in safety or efficacy of nateglinide between patients age 65 and over, and those under age 65. However, greater sensitivity of some older individuals to nateglinide therapy cannot be ruled out.
8.6Renal Impairment No dosage adjustment is recommended in patients with mild to severe renal impairment [see Clinical Pharmacology ( 12.3 ) ].

🧓 Geriatric Use ▾
8.5Geriatric Use 436 patients 65 years and older, and 80 patients 75 years and older were exposed to nateglinide in clinical studies. No differences were observed in safety or efficacy of nateglinide between patients age 65 and over, and those under age 65. However, greater sensitivity of some older individuals to nateglinide therapy cannot be ruled out.
🆘 Overdosage ▾
10 OVERDOSAGE There have been no instances of overdose with nateglinide in clinical trials. However, an overdose may result in an exaggerated glucose-lowering effect with the development of hypoglycemic symptoms. Hypoglycemic symptoms without loss of consciousness or neurological findings should be treated with oral glucose and adjustments in dosage and/or meal patterns.
Severe hypoglycemic reactions with coma, seizure, or other neurological symptoms should be treated with intravenous glucose. As nateglinide is highly protein bound, dialysis is not an efficient means of removing it from the blood.
🧬 Clinical Pharmacology ▾
12 CLINICAL PHARMACOLOGY
12.1Mechanism of Action Nateglinide lowers blood glucose levels by stimulating insulin secretion from the pancreas. This action is dependent upon functioning beta-cells in the pancreatic islets. Nateglinide interacts with the ATP-sensitive potassium (K+ ATP ) channel on pancreatic beta-cells.
The subsequent depolarization of the beta cell opens the calcium channel, producing calcium influx and insulin secretion. The extent of insulin release is glucose dependent and diminishes at low glucose levels. Nateglinide is highly tissue selective with low affinity for heart and skeletal muscle.
12.2Pharmacodynamics Nateglinide stimulates pancreatic insulin secretion within 20 minutes of oral administration. When nateglinide is dosed before meals, the peak rise in plasma insulin occurs approximately 1 hour after dosing and falls to baseline by 4 hours after dosing.
12.3Pharmacokinetics In patients with Type 2 diabetes, multiple dose administration of nateglinide over the dosage range of 60 mg to 240 mg shows linear pharmacokinetics for both area under the curve (AUC) and C max . In patients with Type 2 diabetes, there is no apparent accumulation of nateglinide upon multiple dosing of up to 240 mg three times daily for 7 days. Absorption Absolute bioavailability of nateglinide is approximately 73%.
Plasma profiles are characterized by multiple plasma concentration peaks when nateglinide is administered under fasting conditions. This effect is diminished when nateglinide is taken prior to a meal. Following oral administration immediately prior to a meal, the mean peak plasma nateglinide concentrations (C max ) generally occur within 1 hour (T max ) after dosing.
T max is independent of dose. The pharmacokinetics of nateglinide are not affected by the composition of a meal (high protein, fat, or carbohydrate). However, peak plasma levels are significantly reduced when nateglinide is administered 10 minutes prior to a liquid meal as compared to solid meal.
When given with or after meals, the extent of nateglinide absorption (AUC) remains unaffected. However, there is a delay in the rate of absorption characterized by a decrease in C max and a delay in time to peak plasma concentration (T max ). Nateglinide did not have any effect on gastric emptying in healthy subjects as assessed by acetaminophen testing.
Distribution Following intravenous (IV) administration of nateglinide, the steady-state volume of distribution of nateglinide is estimated to be approximately 10 L in healthy subjects. Nateglinide is extensively bound (98%) to serum proteins, primarily serum albumin, and to a lesser extent α1 acid glycoprotein. The extent of serum protein binding is independent of drug concentration over the test range of 0.1 to 10 mcg/mL.
Elimination In healthy volunteers and patients with type 2 diabetes mellitus, nateglinide plasma concentrations declined with an average elimination half-life of approximately 1.5 hours. Metabolism In vitro drug metabolism studies indicate that nateglinide is predominantly metabolized by the cytochrome P450 isozyme CYP2C9 (70%) and to a lesser extent CYP3A4 (30%). The major routes of metabolism are hydroxylation followed by glucuronide conjugation.
The major metabolites are less potent antidiabetic agents than nateglinide. The isoprene minor metabolite possesses potency similar to that of the parent compound nateglinide. Excretion Nateglinide and its metabolites are rapidly and completely eliminated following oral administration.
Eighty-three percent of the 14 C -nateglinide was excreted in the urine with an additional 10% eliminated in the feces. Approximately 16% of the 14 C -nateglinide was excreted in the urine as parent compound. Specific Populations Renal Impairment No pharmacokinetic data are available in subjects with mild renal impairment (CrCl 60 to 89 mL/min).
