Abstract

Objectives: Cholinesterase inhibitors for the treatment of Alzheimer's Disease (AD) and antimuscarinic agents for the treatment of urge urinary incontinence (UUI) may reduce the potential effect of each other in the patients with both diseases. Trospium has a relatively low lipophilicity and low CNS penetration, and galantamine, a cholinesterase inhibitors, has also allosterically modulates nicotinic cholinergic receptors. This study was designed to evaluate the effects of dual use of trospium and galantamine for 6 months in the elderly patients with AD and UUI.

Setting/participants: One hundred and seventy eight elderly patients: 99 UUI patients (Group I, treated with trospium), 43 AD patients (Group II, treated with galantamine) and 36 AD and UUI patients (Group III, treated with galantamine and trospium) were evaluated by geriatric assessments, the Global Perception Index (GPI), Patients' Satisfaction Question (PSQ), Estimated Patients' Improvement (EPI), nocturia and pads/day at baseline and in the 6th month.

Results: Trospium increased the satisfaction of the patients in Groups I and III according to the EPI, PSQ, GPI, number of nocturia and pads/day. Decreasing in the GDS score was significant in the Group I and III (p < 0.05). Decreasing in the ADL score was significant in the Group III (p < 0.05). The MMSE scores were not significantly changed in the all groups during the 6 months.

Conclusion: Consequently, we have thought that a combination of trospium and galantamine could be recommended for the management of the elderly patients with UUI and AD, which are common problems in the elderly.

The mean change from the baseline in the average number of nocturia episodes and pads per day during the 6 months of treatment with trospium in patients with UI (UI+DEM-) and UI plus dementia (UI+DEM+). The reductions in the number of nocturia and pads were recorded at each time point, but a significant difference was observed in the number of nocturia episodes in the UI+DEM- and UI+DEM+ groups (p<0.05 for each comparison). Furthermore, no increase in the nocturia episodes and pads/day was observed in the patients with dementia (p>0.05)
