Belgian multicenter clinical study of alfuzosin, a selective alpha 1-blocker, in the treatment of benign prostatic hyperplasia. The Alfuzosin Belgian Group.

The effects of alfuzosin, a potent alpha 1-blocker, were assessed in patients with benign prostatic hyperplasia, in a double-blind, multicenter, placebo-controlled, cross-over study. Treatment duration was 4 weeks for both alfuzosin and placebo. A significant beneficial effect of alfuzosin (7.5 to 10 mg a day) on clinical subjective and objective criteria was observed as compared to placebo: total Boyarsky score decreased by 1.63 points, peak urinary flow improved by 2.03 ml/sec. Alfuzosin was well tolerated, the observed adverse events corresponded to the pharmacological properties of this compound, and resolved rapidly.
