View in Spanish: Viadur

Viadur (VY-uh-door)
A drug used to treat symptoms of advanced prostate cancer. It is also being studied in the treatment of other conditions and types of cancer. The active ingredient leuprolide blocks the body from making testosterone (a male hormone) and estradiol (a female hormone). It may stop the growth of prostate cancer cells that need testosterone to grow. Some brands of leuprolide are also used to treat early puberty in children and certain gynecologic conditions. Viadur is a type of gonadotropin-releasing hormone analog. Also called Eligard, leuprolide acetate, and Lupron.
