Combined treatment of patients with erectile dysfunction and urination disorders

Abstract The article presents the results of the study aimed to the evaluation the efficacy of combination therapy with alpha1-blocker (tamsulosin) and phosphodiesterase type 5 inhibitor (sildenafil) in patients with urination disorders and erectile dysfunction (ED). A pilot observational study involving 60 men aged from 50 and 80 years divided into 3 groups of 20 people was performed. Group 1 of patients received sildenafil 25 mg daily (dynamico), Group 2--tamsulosin 0.4 mg daily (Omnic-Ocas), and Group 3--tamsulosin 0.4 mg (Omnic-Ocas) and sildenafil 25 mg (dynamico) daily. The visits were carried out at the stage of screening, further--every 10 days (a total number--4 visits). Combination therapy of urination disorders and ED contributed to the significant improvement in uroflowmetry, the stopping of complaints according to the IPSS and IIEF-15 questionnaires, and improving the quality of life (according to the QoL questionnaire). Combination therapy significantly decreased obstructive and irritative symptoms, increased the maximum urine flow rate within the period of observation, as well as significantly decreased the residual urine volume, more pronounced when compared with monotherapy. Significant positive effect on erectile component and all components of the overall satisfaction in the sexual sphere were registered, that as a consequence led to the positive impact on the quality of life in patients treated with PDE5 inhibitor. Given the high prevalence of urinary disorders and erectile dysfunction, combined therapy with alpha1-blockers and PDE5 inhibitors in this case should be a promising area for drug therapy.
