Aims: To determine the economic benefit of losartan versus atenolol in patients with essential hypertension from the perspective
of the Swiss healthcare system.
Methods and results: The cost-effectiveness of losartan versus atenolol in the treatment of hypertension was analyzed by applying the results
of the LIFE study to the Swiss healthcare system using a decision analysis framework.
The cost-effectiveness shows the losartan cohort to provide an additional life expectancy of 0.05 years per patient compared
to the atenolol cohort, over a mean follow-up period of 4.8 years. Losartan therapy in hypertensive patients produced net
cost savings of CHF 24 per patient and per 4.8 years compared to atenolol from the perspective of the Swiss health care system.
This result was robust after varying costs of medication, stroke, myocardial infarction and life expectancy.
Conclusion: The use of a losartan-based regimen in hypertensive patients with left ventricular hypertrophy in Switzerland is net cost-saving
compared with a atenolol-based regimen.
