A synthetic 4-azasteroid compound with antiandrogenic activity. Dutasteride competitively and specifically binds to isoenzymes 1 and 2 of 5-alpha-reductase, forming stable enzyme complexes and inhibiting the conversion of testosterone to 5α-dihydrotestosterone (DHT); the reduction in DHT activity may mitigate or prevent enlargement of the prostate gland. The type 2 5-alpha-reductase isoenzyme is primarily active in the reproductive tissues while the type 1 isoenzyme is also active in skin and the liver. Check for active clinical trials or closed clinical trials using this agent. (NCI Thesaurus)
