Abstract
The storage (irritative) and voiding (obstructive) symptoms associated with benign prostatic hyperplasia are generally attributed to prostate enlargement and increased prostatic smooth muscle tone mediated by the prevailing α1-adrenoceptors in the bladder neck and prostate. This results in obstruction and subsequent secondary changes to the bladder. However, there is growing evidence that many of these symptoms may be due to changes in extraprostatic α1-adrenoceptors, possibly α1D-adrenoceptors. Findings from the VA cooperative trial challenge the current theory that the common side effects associated with these agents are due to vascular action of α1-adrenoceptor blockers.
