摘要

Recently, a debate has been raised regarding the place and the role of sulfonylureas (SU) amongst the armamentarium of drugs available for treatment of hyperglycemia in subjects with type 2 diabetes mellitus. With the advent of new drugs, SUs are being relegated and denigrated by some authorities contrary to present recommendations by various organizations e.g. American Diabetes Association, European Association for the Study of Diabetes and International Diabetes Federation. In this article, the advantages of SUs over the new agents in terms of their well established and proven better efficacy as well as their short term and long term (over 50 years) safety based on extensive literature data are documented. Moreover, lower costs of SUs render them to be far more cost effective when compared to new agents and therefore make them affordable in many regions of the world. Additionally, SUs are probably the initial drugs of choice in lean subjects with prediabetes and type 2 diabetes because they are the most effective secretogogues and major pathophysiologic mechanism of altered glucose metabolism in lean subjects is the decline in insulin secretion and not rising insulin resistance. Furthermore, SUs are also the most cost effective 2nd line agents in obese subjects with type 2 diabetes on lapse of glycemic control while receiving metformin. Finally, with progression of the disorder, the most cost effective combination of 2 oral agents in conjunction with basal insulin remains to be metformin and SUs. Many studies have documented a significantly greater extra pancreatic effect of glimepiride in comparison to other SUs probably because of its unique property in enhancing insulin sensitivity in conjunction with its ability to stimulate both 1st and 2nd phase insulin secretion. These characteristics may contribute to its greater efficacy with lesser hypoglycemia when compared with other SUs. Lack of hypoglycemic effect of metabolites of glimepiride may also be responsible for lesser hypoglycaemia. Moreover, metabolism
