Overview
11 DESCRIPTION Nateglinide Tablets, USP are an oral blood glucose-lowering drug of the glinide class. Nateglinide, (-)-N-[(trans-4-isopropylcyclohexane)carbonyl]-D-phenylalanine, is structurally unrelated to the oral sulfonylurea insulin secretagogues. The structural formula is as shown: Nateglinide is a white powder with a molecular weight of 317.43.
Mechanism of Action
12 CLINICAL PHARMACOLOGY 12.1 Mechanism 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. 12.2 Pharmacodynamics Nateglinide stimulates pancreatic insulin secretion within 20 minutes of oral administration.
