非那雄胺INN:finasteride)又译非那斯特萊非那司提非那甾胺,是治療前列腺增生雄性禿的藥物,也用於女性毛髮過度生長[1][2]

非那斯特萊會抑制頭髮毛囊的第二型5α還原酶(type 2 5-alpha reductase),使双氢睾酮(Dihydrotestosterone,DHT)的濃度降低。這是由於第二型5α還原酶能夠將睪固酮轉換成双氢睾酮,DHT即是掉髮的元凶,因此非那斯特萊能有效減少掉髮。但有可能會降低性能力,停用藥物後,性功能障礙症狀會消失,但還會持續掉髮。亦有少數報告指出可能會引起憂鬱及自殺傾向[3]柔沛(Propecia 保康絲)的主成份即是非那斯特萊。非那斯特莱的生物半衰期是6小時,容易被小腸吸收。
