The drug, finasteride, is one of the most important treatments available for enlarged prostate. It's based on groundbreaking research conducted at UT Southwestern during the 1970's. At that time, scientists discovered that people with a particular enzyme deficiency didn't develop normal prostates or prostatic enlargement. Finasteride works by inhibiting the action of this enzyme, reducing the levels of the androgen most responsible for enlarged prostate and prostate cancer.
Health Watch is heard Monday through Friday nationwide on the "Stardust" format of ABC Satellite Radio. Call your local radio station and ask if they carry the program.
