Benign prostatic hyperplasia (BPH) is one of the most common pathologies in aging men, associated with lower urinary tract symptoms (LUTS). This pathology has a multimodal approach depending on different factors like age, prostate size, prostate-specific antigen level, and severity of the symptoms .
Medical treatment is the first option in what patients with low or moderate LUTS are concerned. There are two major drug classes already established in all international treatment guidelines, 5 alpha-reductase inhibitors and alpha-blockers. 5 alpha-reductase inhibitors block the transformation of testosterone in dihydrotestosterone within the prostate, leading to the decrease of prostate volume, increased peak urinary flow rate, improvement of symptoms, decreasing the risk of acute urinary retention. Their main secondary effects are the erectile dysfunction, the decreasing of libido and of the ejaculate volume, and also gynecomastia . Alpha-blockers act on alpha-adrenoceptor sites found particularly at the bladder neck, at the trigone and within the prostate. They have a fast action on the prostate gland, leading quickly to symptom relief, but without reducing the risk of acute retention or surgical treatment. As secondary effects, alpha-blockers can affect blood pressure [3-5].
