Abstract
In order to assess the efficacy and safety of alfuzosin, an alpha-1 blocker, in symptomatic patients with benign prostatic hyperplasia (BPH), 131 patients who had completed a 6-month placebo-controlled trial conducted on parallel groups entered a 12-month open study; 122 patients were treated with alfuzosin for 12 months and 56 patients for 18 months. After 12 months, all obstructive and irritative symptoms assessed according to the Boyarsky scale were significantly improved, as were peak flow rates in obstructed patients and mean flow rates and residual urine in the whole population. Voiding symptoms showed sustained improvement after treatment for 12 to 18 months. Only 5.3% of patients experienced vasodilatory side effects, none of which led to withdrawal from the study. No side effect related to long-term administration was reported. Alfuzosin has a beneficial effect on voiding symptoms in patients with BPH and can be safely used in long-term administration.
