GENERIC NAME: terazosin

BRAND NAME: Hytrin (discontinued brand)

DRUG CLASS AND MECHANISM: Terazosin belongs to a class of medications called alpha 1 blockers which relax the smooth muscles of the arteries, the prostate, and the bladder neck. Other alpha blockers include doxazosin (Cardura), alfuzosin (Uroxatral), tamsulosin (Flomax), and prazosin (Minipress). Relaxing the smooth muscles of the arteries lowers blood pressure. Relaxing the smooth muscles around the bladder neck relieves urinary obstruction caused by an enlarged prostate (prostate hypertrophy). Terazosin relaxes the smooth muscles of the bladder neck and the prostate, increasing urine flow. The FDA approved terazosin in 1987.
