摘要
During recent years, pharmacological treatment of symptomatic benign prostatic hyperplasia (BPH) has become the primary treatment choice for an increasing number of patients, The 2 principal drug classes employed are alpha 1-blockers and 5 alpha-reductase inhibitors, Current information from placebo-controlled double-blind clinical trials is reviewed, The effect of alpha 1-blockers on symptoms and objective parameters for bladder outlet obstruction is well documented, However, alpha 1-blockers carry a small but significant incidence of adverse effects, Parameters for identification of patients who will respond well to alpha 1-blockers have yet to be identified, and data concerning the long term effects of these drugs are not yet available. 5 alpha-Reductase inhibitors have a slow onset of effect, but treatment leads to improvement in symptoms, reduction of the size of the prostate gland and improvement in objective parameters for bladder outflow obstruction, Approximately 30 to 50% of patients will respond to treatment with 5 alpha-reductase inhibitors. The definitive role of pharmacological treatment in symptomatic BPH remains to be established, although it seems that patients unfit or unwilling to undergo surgical resection of the prostate will benefit from such therapy.
