what is alfuzosin
From Wikipedia, the free encyclopedia. Alfuzosin (INN, provided as the hydrochloride salt) is a pharmaceutical drug of the alpha-1 blocker class. As an antagonist of the alpha-1 adrenergic receptor, it works by relaxing the muscles in the prostate and bladder neck, making it easier to urinate. It is thus used to treat benign prostatic hyperplasia (BPH).
