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...
Read the full MedlinePlus article ↗- It helps lower blood sugar in adults with type 2 diabetes, along with diet and exercise. It is not for type 1 diabetes or diabetic ketoacidosis.
- Take it 1 to 30 minutes before each meal, usually three times a day. If you skip a meal, skip that dose too. Follow your prescriber’s directions.
- Low blood sugar. Learn the warning signs and check your blood sugar as advised. Severe lows can cause seizures and need urgent care.
- Common ones include cold or flu-like symptoms, back pain, dizziness, joint problems, diarrhea and some weight gain. Call me or your doctor if you get a rash, itching, hives or yell...

⚠️ 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) 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.
5.2Macrovascular 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) ]
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. Table 1: Adverse Reactions other than Hypoglycemia (%) occurring Greater than or Equal to 2% in Nateglinide -Treated Patients from Pool of 12 to 64 week Placebo Controlled Trials Placebo N=458 Nateglinide N=1,441 Preferred Term Upper Respiratory Infection 8.1

2.4Hypoglycemia Episodes of severe hypoglycemia (plasma glucose less than 36 mg/dl) were reported in two patients treated with nateglinide tablets. Non-severe hypoglycemia occurred in 2.4 % of nateglinide tablets treated patients and 0.4 % of placebo treated patients [see Warnings and Precautions (5.1) ]. Weight Gain Patients treated with nateglinide tablets had statistically significant mean increases in weight compared to placebo.
In clinical trials, the mean weight increases with nateglinide tablets 60 mg (3 times daily) and nateglinide tablets 120 mg (3 times daily) compared to placebo were 1.0 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 tablets alone, nateglinide tablets in combination with metformin, metformin alone, and glyburide alone. The respective differences from placebo were 0.29 mg/dl, 0.45 m9/dl, 0.28 m9/dl, and 0.19 mg/dl.
6.2Postmarketing Experience The following adverse reactions have been identified during post-approval use of nateglinide tablets. 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
🔄 Drug Interactions ▾

👥 Use in Specific Populations ▾
8 USE IN SPECIFIC POPULATIONS
8.1Pregnancy There are no adequate and well-controlled studies of nateglinide in pregnant women. It is unknown whether nateglinide can cause fetal harm when administered to a pregnant woman. Nateglinide tablets should be used during pregnancy only if the potential benefit justifies the potential risk to the fetus.
In the rabbit, embryonic development was adversely affected and the incidence of gall bladder agenesis or small gallbladder was increased at a dose of 500 mg/kg (approximately 27 times the human therapeutic exposure of 120 mg three times daily, based on body surface area). Nateglinide was not teratogenic in rats at doses up to 1,000 mg/kg (approximately 27 times the human therapeutic exposure based on body surface area).
8.3Nursing Mothers It is not known whether nateglinide is excreted in human milk. Nateglinide is excreted in rat milk. Offspring of rats exposed to 1,000 mg/kg nateglinide (approximately 27 times the human therapeutic exposure of 120 mg three times daily, based on body surface area) had lower body weight.
Because the potential for hypoglycemia in nursing infants may exist, a decision should be made as to whether nateglinide should be discontinued in nursing mothers, or if mothers should discontinue nursing.
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 tablets between patients age 65 and over, and those under age 65. However, greater sensitivity of some older individuals to nateglinide tablets 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) ]. 8. 7 Hepatic Impairment No dose adjustment is recommended for patients with mild hepatic impairment. Use of nateglinide in patients with moderate-to-severe hepatic impairment has not been studied and therefore, should be used with caution in these patients [see Clinical Pharmacology (12.3) ].

However, greater sensitivity of some older individuals to nateglinide tablets 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 are 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 tablets stimulates pancreatic insulin secretion within 20 minutes of oral administration. When nateglinide tablets are 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 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 tablets are 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 tablets 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 a 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 tablets are 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 14c_nateglinide was excreted in the urine with an additional 10% eliminated in the feces. Approximately 16% of the 14c_Nateglinide was excreted in the urine as parent compound.

Compared to healthy matched subjects, patients with type 2 diabetes mellitus and moderate and severe renal impairment (CrCl 15 to 50 mL/min) not on dialysis displayed similar apparent clearance, AUG, and C MAX . Patients with type 2 diabetes and renal failure on dialysis exhibited reduced overall drug exposure (C MAX decreased by 49%; not statistically significant). However, hemodialysis patients also experienced reductions in plasma protein binding compared to the matched healthy volunteers.
In a cohort of 8 patients with type 2 diabetes and end-stage renal disease (ESRD) (eGFR < 15 mL/min/1.73m 2 ) M1 metabolite accumulation up to 1.2 ng/mL occurred with a dosage of 90 mg once daily for 1 to 3 months. In another cohort of 8 patients with type 2 diabetes on hemodialysis, M 1 concentration decreased after a single session of hemodialysis. Although the hypoglycemic activity of the M1 metabolite is approximately 5 times lower than nateglinide, metabolite accumulation may increase the hypoglycemic effect of… [Excerpted — this section continues on DailyMed.]

14 CLINICAL STUDIES
14.1Monotherapy In a 24-week, double-blind, placebo-controlled study, patients with type 2 diabetes were randomized to receive either nateglinide tablets (60 mg or 120 mg three times daily before meals) or placebo. Patients previously treated with antidiabetic medications were required to discontinue that medication for at least 2 months before randomization. At Week 24, treatment with nateglinide tablets before meals resulted in statistically significant reductions in mean HbA1C and mean fasting plasma glucose (FPG) compared to placebo (see Table 5 ).
The reductions in HbA1C and FPG were similar for patient's naive to, and those previously exposed to, antidiabetic medications.

14.2Monotherapy Compared to Glyburide In a 24-week, double-blind, active-controlled trial, patients with type 2 diabetes who had been on a sulfonylurea for 3 or more months and who had a baseline HbA 1 C greater than or equal to 6.5% were randomized to receive nateglinide tablets (60 mg or 120 mg three times daily before meals) or glyburide 10 mg once daily. Patients randomized to nateglinide tablets had statistically significant increases in mean HbA1C and mean FPG at endpoint compared to patients randomized to glyburide.

14.3Monotherapy and In Combination With Metformin In a 24-week, double-blind, active- and placebo-controlled study, patients with type 2 diabetes were randomized to receive either nateglinide alone (120 mg three times daily before meals), metformin alone (500 mg three times daily), a combination of nateglinide tablets 120 mg (three times daily before meals) and metformin (500 mg three times daily), or placebo. Fifty-seven percent of patients were previously untreated with oral antidiabetic therapy. Patients previously treated with antidiabetic medications were required to discontinue medication for at least 2 months before randomization.
At Week 24, statistically significant reductions in mean HbA1c and FPG were observed with metformin monotherapy compared to nateglinide tablets monotherapy, and the combination of nateglinide tablets and metformin compared to either nateglinide tablets or metformin monotherapy (see Table 7 ). Compared to placebo, nateglinide monotherapy was associated with a statistically significant increase in mean body weight, while no significant change in body weight was observed with metformin monotherapy or combination of nateglinide and metformin therapy (see Table 7 ).
Among the subset of patients previously treated with other antidiabetic agents, primarily glyburide, HbA1C in the nateglinide monotherapy group increased slightly from baseline, whereas HbA1C was reduced in the metformin monotherapy group (see Table 7 ). Table 7: Endpoint results for a 24-week study of Nateglinide Monotherapy and Combination with Metformin Placebo Nateglinide 120 mg three times daily Metformin 500 mg three times daily Nateglinide 120 mg before meals plus Metformin Metformin was administered three times dail… [Excerpted — this section continues on DailyMed.]
🧪 Nonclinical Toxicology ▾
13 NONCLINICAL TOXICOLOGY
13.1Carcinogenesis, Mutagenesis, Impairment of Fertility Carcinogenicity: Nateglinide did not increase tumors in two year carcinogenicity studies conducted in mice and rats. Oral doses of nateglinide up to 900 mg/kg in rats and 400 mg/kg in mice were tested, which produced exposures in rats approximately 30 to 40 times and in mice 10 to 30 times the human therapeutic exposure of nateglinide at a dose of 120 mg three times daily, based on AUC. Mutagenesis: Nateglinide was not genotoxic in the in vM:ra Ames test, mouse lymphoma assay, chromosome aberration assay or in the in vivo mouse micronucleus test.
Impairment of Fertility: Fertility was unaffected by administration of nateglinide to rats at doses up to 600 mg/kg (approximately 16 times the human therapeutic exposure with a recommended nateglinide tablets dose of 120 mg three times daily before meals).
