Metabolism and Elimination: Dutasteride is extensively metabolized in humans. In vitro studies showed that dutasteride is metabolized close the CYP3A4 and CYP3A5 isoenzymes. Both of these isoenzymes produced the 4?-hydroxydutasteride, 6-hydroxydutasteride, and the 6,4?-dihydroxydutasteride metabolites. In summing-up, the 15-hydroxydutasteride metabolite was formed by CYP3A4.
Canadian Pharmacy Avodart Dutasteride is not metabolized in vitro by altruist cytochrome P450 isoenzymes CYP1A2, CYP2A6, CYP2B6, CYP2C8, CYP2C9, CYP2C19, CYP2D6, and CYP2E1. In human serum following dosing to unwavering federal, unchanged dutasteride, 3 primary metabolites (4?-hydroxydutasteride, 1,2-dihydrodutasteride, and 6-hydroxydutasteride), and 2 adolescent metabolites (6,4?-dihydroxydutasteride and 15-hydroxydutasteride), as assessed by load spectrometric rejoinder, fool been detected. The absolute stereochemistry of the hydroxyl additions in the 6 and 15 positions is not known. In vitro, the 4?-hydroxydutasteride and 1,2-dihydrodutasteride metabolites are much less effective than dutasteride against both isoforms of charitable 5 alpha-reductase. The endeavour of 6?-hydroxydutasteride is comparable to that of dutasteride.
