Nateglinide is indicated as an adjunct to diet and exercise to improve glycemic control in adults with type 2 diabetes mellitus.

Nateglinide, a nonsulfonylurea hypoglycaemic agent which stimulates insulin release from the pancreatic β-cells by blocking ATP-dependent K channels, depolarising the membrane and facilitating Ca entry through Ca channels. This action depends on the amount of existing glucose levels.

Initial dose: 120 mg orally 3 times a day before meals

Maintenance dose: 60 to 120 mg orally 3 times a day before meals

For patients who are near goal HbA1c when therapy is initiated, therapy should be initiated at 60 mg orally 3 times. May be used as monotherapy, or in combination with metformin or a thiazolidinedione. As an adjunct to diet and exercise to improve glycemic control in adults with type 2 diabetes mellitus.

Take orally 1 to 30 minutes before a meal. Patients who skip a meal should be instructed to skip the dose for that meal

CYP2C9 and CYP3A4 inhibitors or inducers may alter metabolism of nateglinide. Increased hypoglycaemic effects with MAOIs, nonselective β-adrenergic blockers, NSAIDs, salicylates. Decreased hypoglycaemic effects with corticosteroids, sympathomimetic agents, thiazide diuretics, thyroid hormones.

Drugs should be given only if the potential benefit justifies the potential risk to the foetus.
