Treatment with rivastigmine or galantamine and risk of urinary incontinence: Results from a Dutch database study
Treatment of Alzheimer disease (AD) with cholinesterase inhibitors (ChEIs) may increase the risk of urinary incontinence (UI). Objective: To assess whether ChEI use was associated with the risk of UI among older patients with AD. Methods: A crossover cohort study using the PHARMO Record Linkage System included 10years of data on drug dispensing histories for over two million Dutch residents. Included patients were aged 50 +, free of UI for the last 6months, received a first ChEI prescription during the study period, had at least 12months prior drug exposure history and one subsequent prescript...

Treatment of Alzheimer disease (AD) with cholinesterase inhibitors (ChEIs) may increase the risk of urinary incontinence (UI). Objective: To assess whether ChEI use was associated with the risk of UI among older patients with AD. Methods: A crossover cohort study using the PHARMO Record Linkage System included 10years of data on drug dispensing histories for over two million Dutch residents. Included patients were aged 50 +, free of UI for the last 6months, received a first ChEI prescription during the study period, had at least 12months prior drug exposure history and one subsequent prescription of any drug. UI was defined as a first dispensing of a urinary spasmolytic or of incontinence products for at least 30days. Cox regression with time-varying covariates and multivariate adjustment allowed assessing whether UI incidence was associated with ChEI exposure. Results: Among 3154 patients there were 657 UI cases during a mean follow-up of 5.1years before a first ChEI dispensing, and 499 cases after ChEI initiation, during a mean follow-up of 2.0years. Among the 2700 participants free of UI one year before ChEI initiation, the adjusted hazard ratio (HR) for UI was 1.13 (95% CI: 0.97-1.32) when periods with ChEI use were compared to periods without ChEI use. Sensitivity analyses may suggest an increased risk in the 1st month after ChEI initiation (HR: 1.72, p=0.09) Conclusion: Worsening AD may increase incidence of UI, but no firm association between ChEI treatment and risk of UI could be shown from these data.
