INTRODUCTION: Cholinesterase inhibitors have been shown to improve cognitive function and improve or maintain global function. OBJECTIVE: To estimate the long-term economic impact of treating patients with Alzheimer's disease with galantamine in seven healthcare systems: Australia, Canada, Finland, New Zealand, Sweden, the Netherlands and the UK. METHODS: The time until patients require full-time care (FTC), defined as the consistent requirement for a significant amount of care giving and supervision each day, and the associated costs were evaluated using the 'Assessment of Health Economics in Alzheimer's Disease (AHEAD)' model. Efficacy data were obtained from three clinical trials comparing galantamine with placebo and local cost and resource use data were determined for each country. Forecast costs reported in Euros (2001 value), were made for up to 10 years in each healthcare system. All costs were determined from a perspective somewhat broader than that of a comprehensive payer, including social services. Both benefits and costs were discounted at 3%. RESULTS: Galantamine (16 mg/day) is predicted to delay the need for FTC by 6.8%, thus the cumulative cost of care over 10 years is expected to be reduced, and this offsets much or all of the cost of galantamine. Approximately five patients need to be treated to avoid 1 year of FTC. In each healthcare system, FTC was estimated to account for 61-92% of the cost. Savings were estimated for most of the countries. For those countries with an expected expense, there were reasonable costs per FTC month avoided (euro553, discounted) and costs per quality-adjusted life year gained (euro25,000). CONCLUSION: In addition to the clinical benefits associated with galantamine treatment, the savings predicted from delaying FTC may offset the treatment costs.
