Generic: 60 mg, 120 mg
Brand Names: U.S.
- Antidiabetic Agent, Meglitinide Analog
Nonsulfonylurea hypoglycemic agent which blocks ATP-dependent potassium channels, depolarizing the membrane and facilitating calcium entry through calcium channels. Increased intracellular calcium stimulates insulin release from the pancreatic beta cells. Nateglinide-induced insulin release is glucose-dependent.
Hepatic via hydroxylation followed by glucuronide conjugation via CYP2C9 (70%) and CYP3A4 (30%) to metabolites
Urine (83%, 16% as unchanged drug); feces (10%)
Onset of Action
Insulin secretion: ~20 minutes; Peak effect: 1 hour
Time to Peak
Duration of Action
98%, primarily to albumin
Special Populations: Renal Function Impairment
Compared with healthy subjects, patients with type 2 diabetes and moderate to severe renal impairment (CrCl 15-50 mL/minute) not on dialysis, displayed similar clearance, AUC, and Cmax. Patients with renal failure on dialysis exhibited reduced overall drug exposure. Hemodialysis patients experienced a reduction in plasma protein binding.
Special Populations: Hepatic Function Impairment
The peak and total exposure of nateglinide were increased 30% in patients with mild hepatic insufficiency. Use with caution in patients with chronic hepatic insufficiency.
Use: Labeled Indications
Type 2 diabetes mellitus: For the treatment of adults with type 2 diabetes mellitus as an adjunct to diet and exercise to improve glycemic control.
Hypersensitivity to nateglinide or any component of the formulation; type 1 diabetes; diabetic ketoacidosis (this condition should be treated with insulin)
Management of type 2 diabetes mellitus: Oral: Initial and maintenance dose: 120 mg 3 times daily, 1-30 minutes before meals; may be given alone or in combination with metformin or a thiazolidinedione. Patients close to HbA1c goal at initiation of therapy may be started at 60 mg 3 times daily
Refer to adult dosing.
Dosing: Renal Impairment
Mild to moderate impairment: No dosage adjustment necessary.
Severe impairment: No dosage adjustment necessary. Use with caution; may be more susceptible to glucose-lowering effects.
Dosing: Hepatic Impairment
Mild impairment (Child-Pugh class A): No dosage adjustment necessary.
Moderate to severe impairment (Child-Pugh class B or C): No dosage adjustment provided in manufacturers labeling. Use with caution; has not been studied.
Administer 1-30 minutes prior to meals. Scheduled dose should not be administered if a meal is missed to avoid hypoglycemia.
Nateglinide should be taken 1-30 minutes prior to meals. Scheduled dose should not be taken if meal is missed to avoid hypoglycemia.

Concerns related to adverse effects:
• Hypoglycemia: May cause hypoglycemia; appropriate patient selection, dosage, and patient education are important to avoid hypoglycemic episodes. Ethanol may increase the risk of hypoglycemia; instruct patients to avoid ethanol.
• Adrenal/pituitary impairment: Use with caution in patients with adrenal and/or pituitary impairment; may be more susceptible to glucose-lowering effects.
• Hepatic impairment: Use with caution in patients with moderate-to-severe hepatic impairment.
• Renal impairment: Use with caution in patients with severe renal impairment; may be more susceptible to glucose-lowering effects.
• Stress-related states: It may be necessary to discontinue nateglinide and administer insulin if the patient is exposed to stress (eg, fever, trauma, infection, surgery).
Concurrent drug therapy issues:
• Insulin secretagogues: Patients not adequately controlled on oral agents which stimulate insulin release (eg, glyburide) should not be switched to nateglinide or have nateglinide added to therapy.
• Metformin: Indicated for adjunctive therapy with metformin; not to be used as a substitute for metformin monotherapy.
• Sulfonylureas: Combination treatment with sulfonylureas is not recommended (no additional benefit).
• Elderly: Use with caution in the elderly; may be more susceptible to glucose-lowering effects.
• Malnourished patients: Use with caution in malnourished patients; may be more susceptible to glucose-lowering effects.
Weight, lipid profile, fasting blood glucose (periodically), and HbA1c (at least twice yearly in patients who have stable glycemic control and are meeting treatment goals; quarterly in patients not meeting treatment goals or with therapy change [ADA 2016a]). During dose adjustment, fasting glucose can be used to determine response.
Pregnancy Risk Factor
Adverse events have been observed in animal reproduction studies. Information describing the effects of nateglinide on pregnancy outcomes is limited (Twaites 2007).
In women with diabetes, maternal hyperglycemia can be associated with congenital malformations as well as adverse effects in the fetus, neonate, and the mother (ACOG 2005; ADA 2016c; Kitzmiller 2008; Metzger 2007). To prevent adverse outcomes, prior to conception and throughout pregnancy maternal blood glucose and HbA1c should be kept as close to target goals as possible but without causing significant hypoglycemia (ACOG 2013; ADA 2016c; Blumer 2013; Kitzmiller 2008). Other agents are currently recommended to treat diabetes in pregnant women (ACOG 2013; Blumer 2013).
• Discuss specific use of drug and side effects with patient as it relates to treatment. (HCAHPS: During this hospital stay, were you given any medicine that you had not taken before? Before giving you any new medicine, how often did hospital staff tell you what the medicine was for? How often did hospital staff describe possible side effects in a way you could understand?)
• Have patient report immediately to prescriber signs of low blood sugar (dizziness, headache, fatigue, feeling weak, shaking, a fast heartbeat, confusion, hunger, or sweating) (HCAHPS).
• Educate patient about signs of a significant reaction (eg, wheezing; chest tightness; fever; itching; bad cough; blue skin color; seizures; or swelling of face, lips, tongue, or throat). Note: This is not a comprehensive list of all side effects. Patient should consult prescriber for additional questions.
