title: [Contemporary medical management of the benign prostatic syndrome].
abstract: Two groups of drugs, alpha blockers and 5-alpha-reductase inhibitors (5ARI), are currently widely used for the medical treatment of benign prostatic syndrome (BPS). Alpha blockers are characterized by a rapid onset of efficacy. If given at an adequate dose, all alpha blockers have a similar efficacy, yet quantitative differences regarding side effects exist. The onset of clinical efficacy of 5ARIs is delayed and dependent on prostate volume. Symptom improvement is generally less pronounced than with alpha blockers, yet this difference declines with time. 5ARI, in contrast to alpha blockers, reduce prostate volume and the risk of long-term BPS complications such as prostate surgery or acute urinary retention. The combination therapy of alpha blockers and 5ARI is superior to either monotherapy; however, this superiority becomes evident only after prolonged (>1 year) therapy. Because of additive side effects, this combination should be reserved for BPS patients with a high risk of progression. Regarding plant extracts, no definitive recommendation can be given because of a limited number of high-quality clinical trials. The use of antimuscarinics in men with BPS with a dominance of storage symptoms and without significant obstruction is promising, although further trials, particularly with a longer study duration, are required.
