title: Efficacy and safety of nateglinide in the treatment of type II diabetes mellitus.
abstract: Nateglinide a new short-acting D-phenylalanine derivative represents a new chemical class of drugs for treating type 2 diabetes that is pharmacologically and therapeutically distinct from currently existing agents. Studies in normal patients and those with type 2 diabetes have shown that nateglinide reduces mealtime blood glucose excursions by physiologic regulation of insulin secretion. Nateglinide binds to and inhibits the K+(ATP) channel of the beta-cell, causing membrane depolarisation, with a subsequent influx of extracellular calcium that results in insulin secretion. A total of 105 patients in 5 centres with type II diabetes mellitus were taken according to the inclusion criteria and given drug treatment and were evaluated on their improvement in fasting and postprandial plasma glucose and glycosylated haemoglobin values for efficacy, besides physician's assessment of the overall safety and efficacy. Nateglinide in a dose of 60 mg before three main meals was given and increased to a maximum of 120 mg thrice daily over the first 3-4 weeks. Nateglinide had to be taken 10 minutes before meals. Duration of treatment was 12 weeks. The patients showed decrease in fasting plasma glucose from 2nd week onwards and reduction in glycosylated haemoglobin by 6th week onwards. Postprandial glucose reduction was also significant at the end of 12th week. The frequency of adverse effects was low and no serious adverse effects were encountered.
