The budgetary impact of 5-HT3 receptor antagonists in the management of chemotherapy-induced emesis

Abstract

The study examined the budgetary implications of using 5-hydroxytryptamine3 receptor antagonists (5-HT3RA), granisetron or ondansetron, in the management of chemotherapy-induced emesis (CIE). A treatment model was constructed to represent a baseline of efficacy and costs for treating a cohort of patients with conventional antiemetics. Groups of patients who would be expected to receive the most benefit from 5-HT3RA were then identified and the effect upon costs of using these compounds in a consecutively larger proportion of selected patients was calculated. On the basis of illustrative costs from The Cookridge Hospital in the UK, it was concluded that the new antiemetics can be used in acute emesis with substantial clinical benefit for an increase of 3-10% to total treatment costs. However, for delayed emesis these compounds have not yet shown a clinical advantage, and the increase in total costs of 12-34% is not justified.
