Terazosin Uses

Terazosin is commonly used in the treatment of a few specific conditions. Here are some typical uses:

Management of high blood pressure (hypertension)
Treatment of symptoms of an enlarged prostate (benign prostatic hyperplasia)
Improvement of urinary flow in men with prostate issues

How Terazosin Works

Terazosin works by blocking alpha-1 receptors in the body. This action helps to relax the muscles in the blood vessels, leading to lower blood pressure.

Additionally, by relaxing muscles in the prostate and bladder neck, it helps improve urine flow in men with an enlarged prostate.

This dual action makes it effective for both blood pressure control and urinary symptoms.
