A randomized trial of tropisetron in the prophylaxis of nausea and vomiting induced by chemotherapy

Thirty patients receiving cisplation or non-cisplatin (containing cyclophosphamide and adriamycin) chemotherapy were enrolled in a randomized, crossover study comparing the efficacy of single dose of Navoban (tropisetron, 5 mg) and Kytril (granisetron, 3 mg). The effective control of acute vomiting induced by cisplatin was achieved in 95.2% (20/21) of patients receiving Navoban and 90.5% (19/21) in those receiving Kytril. Complele control rate was 71.4% (15/21) in Navoban arm, and 81.0% (17/21) in Kytril arm. Total control of delayed vomiting (day 2-5) was 71.4%-90.4% in Navoban arm, while it was 66.7%-4% in Kytril arm. The effective control of vomiting induced by non-cisplatin drugs was achieved in 9/9 in both arms. It is concluded that both agents are effective in the control of vomiting induced by chemotherapy. They have identical adverse effects and are well tolerated by the patients.
