Aim. To evaluate the efficiency of long-term use of trospium chloride (Spazmex) for the treatment of patients with neurogenic overactive bladder due to Parkinson's disease (PD) and to determine the influence of therapy on the cognitive status of patients.
Materials and methods: 60 patients with PD and neurogenic overactive bladder with stages 2.5, 3 and 4 according to Hoehn-Yahr scale were included in the main group. The mean age was 58.2±5.7 years. All patients were prescribed trospium chloride at entry into the study, with doses titrated gradually according to clinical efficacy (30 to 90 mg). The comparison group included 15 patients with PD and neurogenic overactive bladder at stages 2,5 and 3, who received tibial neuromodulation according to the standard technique with skin electrodes. The mean age of patients was 56.4±4.6 years. At baseline, both groups were comparable in terms of gender, age and cognitive status (p=0.801). All patients received treatment for 52 weeks. The efficiency of therapy was assessed according to bladder diaries, while safety outcomes included postvoid residual, side effects, cognitive status according to the MoCA scale and quality of life according to the SF-Qualiveen questionnaire. Results: clinical efficacy and satisfaction were achieved in all patients who completed the study (47 patients in the main group and 15 patients in the comparison group). Good clinical efficacy was demonstrated in both groups, since there was a decrease in the number of urinations, episodes of urgency and urinary incontinence. In addition, there was an improvement in the quality of life according to the SF-Qualiveen scale. The cognitive status during the entire follow-up period remained without significant changes in both groups.
Conclusion. Trospium chloride is an effective drug in patients with PD. It does not affect cognitive functions during long-term use. Trospium chloride should be considered as first-line drug in those with urologic manifestations of PD.
