Efficacy of Ondansetron and Lorazepam in Controlling Emesis Associated with Cytotoxic Chemotherapy

Abstract

A phase II study using a combination of Ondansetron and Lorazepam to treat patients receiving either highly or moderately emetogenic chemotherapy regimens has recently been completed. A total of 56 patients were enrolled and data from 53 is amenable to analysis. The overall response rates were 100% and 91% for the highly and moderately emetogenic regimens respectively, with 16 out of 20 patients (80%) and 18 out of 33 patients (54.5%) achieving a complete or major response respectively. Toxicity was mild and no dose modifications were necessary.
