Structural Formula Illustration
Finasteride is a white crystalline powder with a melting point near 250°C. It is freely soluble in chloroform and in lower alcohol solvents, but is practically insoluble in water.
Finasteride is used to shrink an enlarged prostate (benign prostatic hyperplasia or BPH) in adult men. It may be used alone or taken in combination with other medications to reduce symptoms of BPH and may also reduce the need for surgery.Finasteride may improve symptoms of BPH and provide benefits such as decreased urge to urinate, better urine flow with less straining, less of a feeling that the bladder is not completely emptied, and decreased nighttime urination. This medication works by decreasing the amount of a natural body hormone (DHT) that causes growth of the prostate.
