However, there is limited literature available related to caregiver preference or treatment compliance in real-world clinical settings. To date, no such data are available from Asia and the Middle East, which account for a sizeable proportion of patients with Alzheimer’s disease. The objective of this study was to evaluate treatment preference and compliance with oral and transdermal medications in daily clinical practice in an ethnically diverse patient population from Asia and the Middle East with mild-to-moderate Alzheimer’s disease.Patients and methods: RECAP (Real-world Evaluation of Compliance And Preference in the treatment of Alzheimer’s disease) was a 24-week, multicenter, prospective, noninterventional study. Two treatment cohorts were observed during the study: oral (cholinesterase inhibitors or memantine) and transdermal (rivastigmine patch). Caregiver preference, physician preference, and patient compliance were evaluated at week 24.Results: A total of 978 of 1,931 enrolled patients (mean age: 72.8 years; 50.5% female) were in the transdermal cohort. For patients with exposure to both oral and transdermal monotherapy (n=330), a significant caregivers’ preference for the transdermal monotherapy was observed (82.7%; P<0.0001). Of the 89 participating physicians, 71 indicated preference for transdermal monotherapy. Patient compliance was also significantly higher for transdermal than oral monotherapy (P<0.0001).Conclusion: Our study showed higher caregiver and physician preference and greater patient compliance with transdermal monotherapy in daily practice.Keywords: rivastigmine, Alzheimer’s disease, cholinesterase inhibitors, patient compliance, observational study, transdermal patch
