Title: A Randomized Clinical Trial to Evaluate the Efficacy and Safety of 10mg Alfuzosin in the Treatment of Chronic Prostatitis / Chronic Pelvic Pain Syndrome (CP/CPPS) in Recently-Diagnosed and/or Newly-Symptomatic Alpha-blocker Naïve Patients
Brief Summary: The purpose of this randomized clinical trial is to evaluate the efficacy and safety of the alpha adrenergic blocker Alfuzosin (Uroxatral) in men with relatively new onset of chronic prostatitis/chronic pelvic pain syndrome (CP/CPPS). Alfuzosin is a once daily (10 mg capsule), FDA approved medication for an indication in benign prostatic hyperplasia (BPH). The effectiveness of alfuzosin in improving lower urinary tract symptoms in patients with BPH has been documented in a number of placebo-controlled studies. A number of small studies have also suggested that alfuzosin ameliorates CP/CPPS symptoms through a similar alpha-blockade mechanism. This study will enable further testing of this hypothesis
