How Alfuzosin Works

Alfuzosin belongs to a class of medications known as alpha-blockers. It works by relaxing the muscles around the bladder and prostate, making it easier to urinate.

By targeting alpha-1 receptors in the smooth muscle tissue, it helps reduce the resistance to urine flow, easing urinary symptoms.

This relaxation effect helps improve urine flow and decreases symptoms of BPH.
