Finasteride acetate is primarily used in the treatment of androgen-dependent conditions, particularly in the management of male pattern baldness and benign prostatic hyperplasia (BPH). It works by inhibiting the enzyme 5-alpha reductase, which converts testosterone to dihydrotestosterone (DHT), a hormone that contributes to hair loss and prostate enlargement. In the context of hair loss, it helps to slow down hair thinning and promotes regrowth in men. For BPH, it reduces the size of the prostate gland, alleviating urinary symptoms such as difficulty in starting urination, weak stream, and frequent urination. Additionally, it is sometimes used in hormone therapy for transgender women to reduce male-pattern hair growth. Its application is typically in oral tablet form, and it is often prescribed for long-term use under medical supervision.
