Finasteride (marketed as Proscar , Propecia , Fincar , Finpecia , Finax , Finast , Finara , Finalo , Prosteride , Gefina , Appecia , Finasterid IVAX , Finasterid Alternova ) is a synthetic antiandrogen which acts by inhibiting type II 5-alpha reductase , the enzyme that converts testosterone to dihydrotestosterone (DHT). It is used as a treatment in benign prostatic hyperplasia (BPH) in low doses, and prostate cancer in higher doses. A May, 2008 study indicates that Finasteride reduces the rate of prostate cancer by 30% (see below). It is also indicated for use in combination with doxazosin therapy to reduce the risk for symptomatic progression of BPH. Additionally, it is registered in many countries for androgenetic alopecia (male-pattern baldness ). less
