Pharmacokinetics
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 hepatic and complete. First, the medication is metabolized to M1 metabolite by CYP2C9. M1 possesses about 1⁄3 of pharmacological activity of glimepiride, yet it is unknown if this results in clinically meaningful effect on blood glucose. M1 is further metabolized to M2 metabolite by cytosolic enzymes. M2 is pharmacologically inactive. Excretion in the urine is about 65%, and the remainder is excreted in the feces.
