[Negative effects on sexual function of medications for the treatment of lower urinary tract symptoms related to benign prostatic hyperplasia]. / Effets négatifs sur la sexualité des traitements médicamenteux des symptômes du bas appareil urinaire liés a l'hypertrophie bénigne de la prostate.

PURPOSE: The aim of this review is to discuss the negative effects on sexual function of medications for lower urinary tract symptoms secondary to benign prostatic hyperplasia (LUTS-BPH). METHODS: An international non-systematic literature review was performed. It included randomized trials of seven drugs of interest and the summaries of the characteristics of these products. This work did not aim comparison between the drugs. RESULTS: Only maximal reported frequencies are presented in this abstract. With prolonged-release alfuzosin, they were 2.8% vs. 1.3% for erectile dysfunction, compared to placebo and 1% vs. 0% for ejaculatory dysfunction. With doxazosin, the incidence was 5.8% vs. 3.3% for erectile dysfunction, 3.6% vs. 1.9% for reduced libido and 0.4% vs. 1.4% for ejaculatory disorders. The incidence of ejaculatory disorders with tamsulosin, was 11% vs. <1% with the placebo and with silodosin, it was 28.1% vs. 1.1%. With finasteride, at 12 months, the highest frequency was 9% vs. 5% for erectile dysfunction, 4.4% vs. 1.5% for ejaculatory disorders and 6.4% vs. 3.4% for reduced libido. At 24 months, for dutatsteride, frequencies were 7.3% vs. 4.0% for erectile dysfunction, 2.2% vs. 0.8% for ejaculatory disorders and 4.2% vs. 2.1% for reduced libido. For tadalafil, a phosphodiesterase-5 inhibitor, and tolerodine, an anticholinergic drug, no negative effect on ejaculation or libido has been reported. For plant extracts, no sexual adverse effects (AEs) were reported among the most common AEs. CONCLUSION: The medications for LUTS-BPH may alter erection, ejaculation or libido. A greater knowledge of the adverse effects of each of these drugs could guide physicians in the clinical management of men with BPH-LUTS.

[Effects of phosphodiesterase type 5 inhibitors on lower urinary tract symptoms secondary to benign prostatic hyperplasia]. / Effets des inhibiteurs de la phosphodiestérase de type 5 sur les symptômes du bas appareil urinaire associés à une hypertrophie bénigne de la prostate.

PURPOSE: The objective of this literature review was to report currently available clinical data on the effects of phosphodiesterase type 5 inhibitors (PDE5I) on lower urinary tract symptoms (LUTS) secondary to benign prostatic hyperplasia (BPH). METHODS: An international literature review was carried out in February 2012 from the Medline database (National Library of Medicine, United States). Studies on the effects of PDE5I on LUTS secondary to BPH published within the last 15 years (1997 to 2012) were extracted. In total, 12 studies were selected: four studies on sildenafil including one randomized, controlled, double-blind study; one randomized, controlled, double-blind study on vardenafil; and seven studies on tadalafil including five randomized, controlled, double-blind studies and a 1-year open-label extension study. RESULTS: PDE5Is significantly improve the overall international prostatic symptom score (IPSS) compared to placebo. Most often, the maximum urinary flow rate (Qmax) was not significantly increased versus placebo. A statistically significant improvement of Qmax was nevertheless observed in certain studies. CONCLUSION: The available clinical data assessing the efficacy of PDE5 inhibition in LUTS secondary to BPH are convincing. PDE5Is thus are a new therapeutic class in the treatment of this disease and are especially interesting in patients suffering from both LUTS and erectile dysfunction (ED), two frequently associated diseases.
