Glimepiride in type 2 diabetes mellitus: A review of the worldwide therapeutic experience

Background: Sulfonylureas (SUs) have been used for many years as first-line therapy for patients with type 2 diabetes mellitus whose blood glucose levels have not been effectively controlled by diet and exercise alone. Glimepiride is a once-daily SU that was introduced in 1995. Since then, a considerable body of evidence has been amassed regarding its use in type 2 diabetes. Objective: This review provides a comprehensive summary of available data on the pharmacology, pharmacokinetics, efficacy, and safety profile of glimepiride in the treatment of type 2 diabetes. It also examines the use of glimepiride to achieve and maintain good glycemic control in patients with type 2 diabetes in current clinical practice. Methods: Relevant articles were identified through a search of MEDLINE for English-language studies published from 1990 to 2002. The search terms used were glimepiride, sulfonylureas, and type 2 diabetes mellitus. The manufacturer of glimepiride provided additional information. Results: Glimepiride differs from other SUs in a number of respects. In clinical studies, glimepiride was generally associated with a lower risk of hypoglycemia and less weight gain than other SUs. Results of other studies suggest that glimepiride can be used in older patients and those with renal compromise. There is evidence that glimepiride preserves myocardial preconditioning, a protective mechanism that limits damage in the event of an ischemic event. Glimepiride can be used in combination with other oral antidiabetic agents or insulin to optimize glycemic control. Conclusion: Based on the evidence to date, glimepiride is an effective and well-tolerated once-daily antidiabetic drug and provides an important treatment option for the management of type 2 diabetes.
