    Dutasteride

    also GI198745, Avodart, dut

    Dutasteride, sold under the brand name Avodart among others, is a medication primarily used to treat the symptoms of a benign prostatic hyperplasia (BPH), an enlarged prostate not associated with cancer. It is also used to treat pattern hair loss in men as an off-label medication and as an approved medication in South Korea, Japan, and Taiwan. A few months may be required before benefits occur. It is usually taken by mouth; however, topical versions exist for those with hair loss, which are designed to minimize systemic exposure by acting specifically on hair follicles.
