Ondansetron: prevention of nausea & vomiting in cisplatin based chemotherapy.
Ondansetron in the prophylaxis of Cisplatin-induced emesis and nausea. The 5-HT3 antagonist ondansetron clearly offers a new approach to the control of Cisplatin-induced emesis and has been evaluated in Thailand. To evaluate anti-emetic efficacy of ondansetron in the prevention of nausea and vomiting induced by Cisplatin containing cancer chemotherapy regimen, we carried out an open multicentre study from January 1991 to December 1992. In this study, patients receiving Cisplatin based chemotherapy received ondansetron 32 mg as a single intravenous dose over 15 minutes prior to the administration of Cisplatin. This was followed by oral ondansetron 8 mg three times a day, preferably one hour before each meal for 5 days. All patients were chemotherapy naive in-patients and were at least 18 years or older with Karnofsky performance status of at least 60 per cent. The number of emetic episodes, nausea and food intake were recorded during the 24 hours following Cisplatin administration. A total of 103 patients were recruited with 84 (81.6%) evaluable patients (48 men and 36 women) scheduled to receive cisplatin chemotherapy at dose 60 mg/m2 or more (60-100 mg/m2), either as single agent or combination therapy. Complete response (complete control of emesis) was achieved in 60 per cent; major response (1-2 emetic episodes) was 13 per cent; minor response (3-5 emetic episodes) was 13 per cent; and failure (5+ emetic episodes) was 10 per cent. Side effects were very mild and not significant. We conclude that ondansetron is efficacious in protecting patients from Cisplatin induced emesis and nausea.
