Cognitive functions and health-related quality of life in men with benign prostatic hyperplasia and symptoms of overactive bladder when treated with a combination of tamsulosin and solifenacin in a higher dosage

摘要

Aim: To study the cognitive functions and health-related quality of life (HRQoL) in individuals taking a combination of tamsulosin and solifenacin in a higher dosage.Methods: All patients (n=262) were assigned to group A (N=93, tamsulosin 0.4mg+solifenacin 10mg per day), group B (N=83, tamsulosin 0.4mg+solifenacin 20mg), and control group C (N=86; tamsulosin 0.4mg+placebo). The lower urinary tract (LUT) condition was assessed on the scales International Prostate Symptom Score, Over Active Bladder Awareness Tool and uroflowmetry. The state of cognitive status was assessed on the scales Mini-mental State Examination, Controlled Oral Word Association Test, Wechsler Adult Intelligence Scale-Revised, Wechsler III, Color Trails Test, California Verbal Learning Test.Results: The values of cognitive function indicators in the individuals from all groups after treatment did not significantly differ from the respective values at the baseline (p.05). The values of most HRQoL parameters of the functional state of the LUT significantly improved in groups A and B. A significant correlation between the state of cognitive status and HRQoL, as well as LUT was absent (r0.3).Conclusion: The combination of solifenacin in a double dosage along with tamsulosin can be recommended for elderly benign prostatic hyperplasia patients with overactive bladder symptoms.
