Glimepiride

Glimepiride is a sulfonylurea used to manage type 2 diabetes mellitus by stimulating insulin secretion from pancreatic beta cells. Marketed as Amaryl® , it is often prescribed as a second-line therapy when lifestyle changes and Metformin are insufficient. Its fast-acting profile makes it ideal for patients needing rapid glycemic control.
