Pharmacokinetic properties of glimepiride
Absorption | Completely absorbed after oral administration within 1 hour of administration; significant absorption occurs: plasma protein binding is 99.4% and volume of distribution is 8.8 L. Accumulation does not occur after multiple doses. |
Metabolism | The drug is primarily metabolized in the liver by CYP2C9 to the active M1 (hydroxyl) metabolite and then to inactive M2 (carboxy) metabolite. |
Excretion | The main route of excretion is through kidneys. A total of 60% of the metabolites are excreted in urine (predominantly M1) and remainder in feces (predominantly M2). |
