Usage of Finasteride:
Finasteride is for the treatment of benign prostatic hyperplasia (BPH), Finasteride may improve the symptoms associated with BPH such as difficulty urinating, getting up during the night to urinate, hesitation at the start of urination, and decreased urinary flow.
Finasteride is also used to treat male pattern hair loss (androgenetic alopecia) in men only. Finasteride reduces the 2 enzymes responsible for the conversion of testosterone to DHT, thus inhibiting hair loss and encouraging hair growth. It is thought that once the DHT accumulation is removed from the hair follicle, the natural growth cycle will takes over.
Propecia (finasteride) is used to treat male pattern baldness (androgenic alopecia) in men. Topically (on the scalp itself) it is of some effect in minimizing further hair loss. In combination with Nizoral and spironolactone (which smells awful, by the way) it can actually reverse loss moderately.
Used for the treatment of prostate disease first. Clinical studies suggest that, with finasteride 1 mg/day, continuous oral 3 months or slightly long can have hair growth, after continuous treatment 1 year hair growth rate to 48%, and can continue to fall off, taking the hair organization 2 years hair growth rate reached 66% ~ 83%.
Finasteride is a 4-- aza-steroid compound which is a specific inhibitor of the metabolism of testosterone within dihydro testosterone become stronger during the cell type-II enzyme 5a-reductase. The enlarged prostate called benign prostatic hyperplasia or prostate depends on the conversion of testosterone to dihydro-testosterone.
Finasteride is an 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. 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).
