Description: Alfuzosin HCl 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). Alfuzosin is marketed in the United States by Sanofi Aventis under the brand name Uroxatral and elsewhere under the tradename Xat or Xatral, and in Egypt under name of Prostetrol. Alfuzosin was approved by the FDA for treatment of BPH in June 2003.
