Hytrin

1 What is Hytrin?

Brand: Hytrin

Generic: Terazosin

Hytrin is an antihypertensive drug under the alpha blocker group, used to treat high blood pressure or hypertension and symptoms of prostate enlargement (Benign Prostatic Hypertrophy or BPH). This medication relaxes the blood vessels to make the blood flow easily and smoothly. This reduces the high blood pressure and decreases the chance of having heart attack, stroke and kidney disease.

Terazosin also relaxes the prostate and bladder neck muscle to relieve urination problems related to BPH.
