OBJECTIVE
We evaluated the antiemetic efficacy of tropisetron, a 5-HT3 receptor antagonist, during its compassionate use in children with malignant disease who during previous chemotherapy cycles experienced emesis refractory to metoclopramide-based treatments.
METHODS
Tropisetron was given to 15 children (eight boys and seven girls 18 months to 18 years of age) with miscellaneous neoplasms. Generally 5 mg/day of tropisetron was administered i.v. the first day of cisplatin-based chemotherapy and i.v. or orally each subsequent day of chemotherapy. The dose of tropisetron was reduced to 2 mg/day in children < 2 years of age and weighing < 20 kg.
RESULTS
Vomiting was well controlled (no more than two episodes per day) on 118 of the 184 days of treatment with tropisetron (64%). No clinically important variations were observed in blood pressure, heart rate, body temperature, or electrocardiographic findings attributable to tropisetron. Transient, mild to moderate side effects (headache, constipation, abdominal pain, diarrhea) occurred in five patients on 11 of the 184 days of tropisetron treatment (6%).
CONCLUSIONS
The results obtained during compassionate use of tropisetron confirm that it is a valid, safe, and manageable antiemetic for the treatment of pediatric patients.
