Abstract

PURPOSE
The aim of this study was to investigate the safety and the effects of elevated doses of solifenacin and trospium on cognitive function and health-related quality of life (HRQoL) in elderly women receiving treatment for urinary incontinence.
METHODS
The study included 312 women aged 60-83 years (mean age, 69.4 years). All participants had scored at least 24 points on the Mini-Mental State Examination (MMSE) scale, and all of them had been diagnosed with urge urinary incontinence (UUI) or mixed urinary incontinence (MUI). The women were randomly assigned to 3 groups: group A, individuals who were simultaneously administered solifenacin at a high dosage of 20 mg per day and trospium at a high dosage of 60 mg per day; group B, persons taking solifenacin and trospium at the usual dosage of 10 and 30 mg per day, respectively; and group C, persons who received a placebo. Participants' cognitive status was assessed by the MMSE, Controlled Oral Word Association Test, Wechsler Adult Intelligence Scale-Revised, Wechsler Memory Scale III, Colour Trails Test, and California Verbal Learning Test scales. The HRQoL assessment was performed using the Medical Outcomes Study 36-Item Health Survey.
RESULTS
The cognitive function parameters did not differ at the start and end of the study across the groups (P>0.05). Additionally, the cognitive function parameters did not differ significantly within each group between the start and end of the study (P>0.05). The values of most HRQoL parameters regarding the functional state of the lower urinary tract (LUT) after the termination of treatment significantly improved in groups A and B (P < 0.05). A significant correlation between cognitive status and HRQoL or LUT parameters was absent (r < 0.3), while the correlations between HRQoL and LUT parameters were r=0.31-0.83, P < 0.05.
CONCLUSIONS
The use of elevated doses of solifenacin and trospium did not increase the risk of cognitive impairment in women with UUI and MUI. The combination of solifenacin and trospium at a double dosage may be recommended to elderly women with treatment-resistant symptoms of UUI and MUI. However, the safety of combining antimuscarinic drugs in women with an increased volume of residual urine requires further study.
