Pharmacological properties:

Pharmacokinetics. At intake it is well soaked up (especially in acid medium of a stomach). Ketokonazol is well dissolved in lipids that promotes high bioavailability (75-90%). Cmax is reached in plasma of 3,5 mg/ml in 2 hours after a single dose in 200 mg of drug during food. Contacts proteins of plasma (albuminous fraction) makes 99%. An insignificant part of drug gets into cerebrospinal fluid and urine. Ketokonazol is metabolized in a liver, way oxidation and splitting of imadazolny and piperazinovy rings, oxidizing O-dealkylation and an aromatic hydroxylation. Removal from plasma two-phase: within the first 10 hours the elimination half-life (Т½) makes 2 hours, and in the subsequent-8 hours. 13% - with urine are allocated in an invariable look and in the form of inactive metabolites, generally with bile, and.
