Randomized Controlled Trial Clinical Trial
A double-blind, crossover, randomized comparison of granisetron and ramosetron for the prevention of acute and delayed cisplatin-induced emesis in patients with gastrointestinal cancer: is patient preference a better primary endpoint?
Serotonin receptor antagonists are recommended by the American Society of Clinical Oncology for the prevention of acute and delayed chemotherapy-induced emesis. However, the most effective agent in this class of antiemetic drugs for preventing emesis has not been clearly defined. We therefore performed a double-blind, crossover, randomized, controlled trial comparing the efficacy of granisetron and ramosetron, using patient preference as the primary endpoint. ⋯ (1) A significant proportion of patients prefer granisetron over ramosetron for the prevention of chemotherapy-induced emesis. (2) Granisetron and ramosetron possess similar effectiveness for the suppression of emesis. (3) The variable of 'patient preference' should be accepted as a primary endpoint of antiemetic drug efficacy.
