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).
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.
Alfuzosin should be used with caution in patients with severe renal insufficiency, and should not be prescribed to patients with a known history of QT prolongation who are taking medications known to prolong the QT interval.
