Cost-effectiveness analysis of antiemetic treatment

Abstract

To address the economic issues posed by the introduction of 5-hydroxytryptamine3 receptor antagonist (5-HT3 RA), we performed a cost-effectiveness analysis based on clinical trial data published in the recent literature. Cost calculations include initial treatment and a second-line salvage treatment. The average cost and incremental cost were established. Incremental cost corresponds to the extra cost involved in achieving total control of emesis in 1% extra patients. If 5-HT3 RA is not part of the initial treatment, salvage treatment with ondansetron is not cost-effective. Moreover, starting with the combination of ondansetron plus dexamethasone saves more money than starting with ondansetron alone. However, if the difference in emesis control is only minimal, treatment with the 5-HT3 RA remains more expensive.
