Resource Ultilisation and Cost Analysis of Memantine in Patients with Moderate to Severe Alzheimer‘s Disease Wimo A., Winblad B., Stöffler A., Wirth Y., and Möbius H. J. Pharmacoeconomics 2003, 21 (5): 327-340
Study Design No. of patients N = 252 (outpatients) Diagnosis Probable Alzheimer’s disease Design Double-blind, randomized, placebo- controlled, multicenter study Age 50 years (mean 76) Severity MMSE 3 – 14 (mean 7.9) GDS 5 – 6 FAST 6a Dose; duration 20 mg Memantine/day; 28 weeks Pharmaco- Resource Utilisation in Dementia (RUD) economic analysis Wimo et al., Pharmacoeconomics 2003

Summary • Caregiver time and institutionalization were the main cost drivers • Average monthly caregiver costs were $ 824 lower in the memantine group* • Average monthly societal costs were $ 1090 lower in the memantine group* • Conclusion:Memantine treatment may lead to significant cost savings by reduction of resource utilization * corrected for confounding effects Wimo et al., Pharmacoeconomics 2003
