AbstractWe studied the role of dexamethasone (DEX) administered on day 1 in controlling cisplatin-induced delayed emesis. Forty patients were randomly allocated to receive either granisetron (GRN) and DEX on day 1, or the same dose of GRN alone. On days 2-5, all the patients received metoclopramide and DEX. They were crossed over to the other antiemetic regimen with their second course of chemotherapy. Thirty-one patients were evaluable for efficacy. The mean visual analogue scale scores for nausea on days 1 and 2 were 9.1 and 18.8 mm for GRN and DEX, and 16.3 and 28.5 mm for GRN alone, respectively (P<0.05 on day 2). The mean numbers of emetic episodes on days 1-3 were 0.036, 0.46 and 0.36 for GRN and DEX, and 0.39, 0.89 and 0.57 for GRN alone, respectively (P<0.01 on day 1). Hiccups and restlessness were noted in 38% and 33% of cycles, respectively. Addition of DEX to GRN on day 1 thus enhanced the control of delayed emesis.
