The efficacy and tolerability of tropisetron in preventing cisplatin-induced nausea and vomiting was studied in 2 open trials and compared with the efficacy and tolerability of metoclopramide plus lorazepam in a randomised crossover trial. In the first study, tropisetron 10mg was administered intravenously over 15 minutes before the cisplatin infusion and a second 10mg dose was given after the 60-minute infusion of cisplatin (greater than 50 mg/m2) in 54 patients with advanced cancers, for a total of 165 courses. Good responses for nausea and vomiting were recorded in 83.0% and 87.9% of courses, respectively, with complete protection from nausea and vomiting in 44.8% and 66.1% of courses, respectively. In the second study in 25 patients whose characteristics and cisplatin schedule were comparable with those of the first study, very similar results were achieved in 104 courses of chemotherapy, despite a reduction in tropisetron dose to a single 5mg intravenous infusion 15 minutes before cisplatin. The efficacies of intravenous tropisetron 5mg and metoclopramide 2 mg/kg plus lorazepam administered 15 minutes before cisplatin in preventing acute and delayed nausea and vomiting were compared in a randomised crossover study involving 20 patients. Tropisetron was significantly superior (p less than 0.001) in controlling both acute and delayed (day 1) symptoms. In all studies, the tolerability of tropisetron was excellent. The most frequent side effect was mild to moderate headache, occurring in 5 to 7% of patients. In conclusion, our experience suggests that tropisetron is an effective and well tolerated antiemetic drug that improves the quality of life of cancer patients administered highly emetogenic chemotherapy regimens.

Abstract
The efficacy and tolerability of tropisetron in preventing cisplatin-induced nausea and vomiting was studied in 2 open trials and compared with the efficacy and tolerability of metoclopramide plus lorazepam in a randomised crossover trial. In the first study, tropisetron 10mg was administered intravenously over 15 minutes before the cisplatin infusion and a second 10mg dose was given after the 60-minute infusion of cisplatin (greater than 50 mg/m2) in 54 patients with advanced cancers, for a total of 165 courses. Good responses for nausea and vomiting were recorded in 83.0% and 87.9% of courses, respectively, with complete protection from nausea and vomiting in 44.8% and 66.1% of courses, respectively. In the second study in 25 patients whose characteristics and cisplatin schedule were comparable with those of the first study, very similar results were achieved in 104 courses of chemotherapy, despite a reduction in tropisetron dose to a single 5mg intravenous infusion 15 minutes before cisplatin. The efficacies of intravenous tropisetron 5mg and metoclopramide 2 mg/kg plus lorazepam administered 15 minutes before cisplatin in preventing acute and delayed nausea and vomiting were compared in a randomised crossover study involving 20 patients. Tropisetron was significantly superior (p less than 0.001) in controlling both acute and delayed (day 1) symptoms. In all studies, the tolerability of tropisetron was excellent. The most frequent side effect was mild to moderate headache, occurring in 5 to 7% of patients. In conclusion, our experience suggests that tropisetron is an effective and well tolerated antiemetic drug that improves the quality of life of cancer patients administered highly emetogenic chemotherapy regimens.
