Comparison of the efficacy and side-effects of ondansetron and metoclopramide-diphenhydramine administered to control nausea and vomiting in children treated with antineoplastic chemotherapy: a prospective randomized study

Abstract

Nausea and vomiting following antineoplastic therapy in patients receiving chemotherapy remains a problem. To prevent nausea and vomiting due to antineoplastic therapy, many types of drugs have been used. Ondansetron and the combination metoclopramide-diphenhydramine have been widely used in children. In this prospective randomized study these drugs were compared both for their efficacy and side-effects in children treated with antineoplastic chemotherapy (with and without cisplatin) the number of chemotherapy courses being equal in both groups. Ondansetron gave complete anti-emetic cover in five of nine courses in patients treated with cisplatin. Metoclopramide-diphenhydramine gave complete anti-emetic cover in one out of nine courses, and 17 out of 23 courses in patients treated without cisplatin. Metoclopramide-diphenhydramine produced side effects in nine courses whereas ondansetron produced side-effects in three courses.

Conclusion: Ondansetron appeared to be superior to metoclopramide-diphenhydramine in the control of emesis induced by chemotherapy regimens containing cisplatin. The results of the present prospective randomized study indicate that ondansetron is a useful anti-emetic in the treatment of chemotherapy-induced emesis.
