The clinical role of alpha-blockers in the treatment of benign prostatic hyperplasia.

Benign prostatic hyperplasia (BPH) is a highly prevalent condition that represents a significant health problem, which is likely to worsen as the population continues to age. alpha-1 adrenoceptor antagonists have been used in the treatment of this condition for well over 20 years and much is now known about their effects on the urinary tract. As these drugs have improved, their use as a first line treatment option in patients with lower urinary tract symptoms (LUTS), secondary to BPH, has continued to increase. This review details some of the background and rationale for the use of these drugs and, using the available information, compares their efficacy and tolerability profiles.
