Cost-effectiveness of vortioxetine versus venlafaxine (extended release) in the treatment of major depressive disorder in South Korea

초록

Objective: To assess the cost-effectiveness of vortioxetine versus venlafaxine XR (extended-release) in major depressive disorder (MDD) patients in South Korea.Methods: A 1-year cost-effectiveness analysis from a limited societal perspective was performed using a combined model consisting of a decision-tree and a Markov model. Patients entered the model when initiating or switching antidepressant treatment following inadequate response to previous treatment. Remission, relapse and recovery were the main health states.Results: Vortioxetine dominated venlafaxine XR, with quality-adjusted life year (QALY) gains of 0.0131 and cost savings of KRW 623,229/year [US$530/year] from a limited societal perspective. Safety contributed more than efficacy to the incremental QALY gains. More patients were in recovery after initial treatment and after 1year with vortioxetine (31%, 40%) compared to venlafaxine XR (23%, 36%). Vortioxetine remained dominant in 98% of probabilistic simulations.Conclusion: Vortioxetine dominated venlafaxine XR in South Korea and is a relevant treatment option for MDD patients initiating or switching therapy.
