AbstractThe anti-emetic effect of ondansetron in cisplatin induced nausea and vomiting was studied in a randomized cross-over trial in 52 patients. The dose of cisplatin was 80-120 mg/M2 iv drip given in 1-3 days. The patients randomly received ondansetron or our routine anti-emetic regimen in the first cycle of chemotherapy. All the patients were crossed-over to the other anti-emetic regimen on the second cycle of the same cisplatin containing regimen. The results showed that ondansetron was superior to our routine anti-emetic regimen in controlling acute nausea and vomiting. 86% of patients treated with ondansetron and 20.4% treated with the routine regimen had a complete or marked response (O-2 emetic episodes). The mean frequency of vomiting were 1.3 times in ondansetron and 8.0 times in the routine regimen (P less than 0.01). Control of delayed emesis was comparable in the two arms. No patient had neurological symptoms in the ondansetron group whereas 4 patients in the routine group had extrapyramidal symptoms.
