Nateglinide is a drug for the treatment of type 2 diabetes. Nateglinide was developed by Ajinomoto, a Japanese company and sold by the Swiss pharmaceutical company Novartis. Nateglinide belongs to the meglitinide class of blood glucose-lowering drugs. Nateglinide lowers blood glucose by stimulating the release of insulin from the pancreas. It achieves this by closing ATP-dependent potassium channels in the membrane of the β cells. This depolarizes the β cells and causes voltage-gated calcium channels to open. The resulting calcium influx induces fusion of insulin-containing vesicles with the cell membrane, and insulin secretion occurs. Nateglinide is contraindicated in patients who have known hypersensitivity to the compound or any ingredient in the formulation,and are affected with type 1 (namely insulin-dependent) diabetes mellitus.
