Randomized Controlled Trial Comparative Study Clinical TrialComparative efficacy of three 5-HT3 antagonists (granisetron, ondansetron, and tropisetron) plus dexamethasone for the prevention of cisplatin-induced acute emesis: a randomized crossover study.
The purpose of this study was to compare the antiemetic efficacy of three 5-HT3 antagonists (granisetron, ondansetron, tropisetron) plus dexamethasone for the prevention of acute emesis induced by high-dose cisplatin chemotherapy. This was a randomized, open label, crossover study. Recruited into the study were 94 chemotherapy-naive patients of whom five were excluded because chemotherapy was not given, noncisplatin regimen was used instead, or presence of anticipatory vomiting. ⋯ The three 5-HT3 antagonists, when used in combination with steroids, had similar major efficacy for prophylaxis against cisplatin-induced acute emesis. Although GRADEX was superior to TRODEX in terms of complete response, this may not be of clinical significance. The choice of antiemetic regimens should therefore depend on patient preference and drug cost.
