[Progress in the studies of alpha1-receptor blocker for benign prostatic hyperplasia].

Benign prostatic hyperplasia (BPH) is a common senile disease, and its main clinical manifestation is lower urinary tract symptom (LUTS), which has long been afflicting old male patients. Previous study showed that alpha1-receptor in the prostate was involved in the development of LUTS. At present, alpha1-receptor blocker is generally accepted as a choice drug for treating BPH and relieving LUTS. The article reviews the tissue distribution of alpha1-receptor and clinical application of alpha1-receptor blocker.
