It is regarded as a second-line option compared to [[metformin]], due to metformin's well-established safety and efficacy. Use of glimepiride is recommended in conjunction with [[Lifestyle modification|lifestyle modifications]] such as diet and exercise. It is taken by mouth, reaching a peak effect within three hours and lasting for about a day. | ||

Glimepiride is indicated to treat [[type 2 diabetes]]; its mode of action is to increase insulin secretion by the pancreas. However it requires adequate insulin synthesis as prerequisite to treat appropriately. It is not used for [[type 1 diabetes]] because in type 1 diabetes the pancreas is not able to produce insulin. | Glimepiride is indicated to treat [[type 2 diabetes]]; its mode of action is to increase insulin secretion by the pancreas.

Side effects from taking glimepiride include [[gastrointestinal tract]] (GI) disturbances, occasional allergic reactions, and rarely blood production disorders including [[thrombocytopenia]], [[leukopenia]], and [[hemolytic anemia]]. In the initial weeks of treatment, the risk of hypoglycemia may be increased. Alcohol consumption and exposure to sunlight should be restricted because they can worsen side effects. | Side effects from taking glimepiride include [[gastrointestinal tract]] (GI) disturbances, occasional allergic reactions, and rarely blood production disorders including [[thrombocytopenia]], [[leukopenia]], and [[hemolytic anemia]].

Like all [[sulfonylureas]], glimepiride acts as an insulin [[secretagogue]]. It lowers blood sugar by stimulating the release of insulin by pancreatic beta cells and by inducing increased activity of intracellular insulin receptors. | Like all [[sulfonylureas]], glimepiride acts as an insulin [[secretagogue]].

Not all secondary sulfonylureas have the same risk of hypoglycemia. Glibenclamide (glyburide) is associated with an incidence of hypoglycemia of up to 20–30%, compared to as low as 2% to 4% with glimepiride. Glibenclamide also interferes with the normal homeostatic suppression of insulin secretion in reaction to hypoglycemia, whereas glimepiride does not. Also, glibenclamide diminishes glucagon secretion in reaction to hypoglycemia, whereas glimepiride does not. | Not all secondary sulfonylureas have the same risk of hypoglycemia.

Gastrointestinal absorption is complete, with no interference from meals. Significant absorption can occur within one hour, and distribution is throughout the body, 99.5% bound to plasma protein. Metabolism is by oxidative biotransformation, it is [[Liver|hepatic]] and complete. First, the medication is metabolized to M<sub>1</sub> metabolite by [[CYP2C9]]. M<sub>1</sub> possesses about {{frac|1|3}} of pharmacological activity of glimepiride, yet it is unknown if this results in clinically meaningful effect on blood glucose. M<sub>1</sub> is further metabolized to M<sub>2</sub> metabolite by cytosolic enzymes. M<sub>2</sub> is pharmacologically inactive. Excretion in the urine is about 65%, and the remainder is excreted in the feces. | Gastrointestinal absorption is complete, with no interference from meals.
