Improved control of cisplatin-induced emesis with a metoclopramide-dexamethasone combination.

Twenty-four patients receiving combination chemotherapy including cisplatin at a dosage of 50 mg/m2 were entered on this antiemetic randomized open cross-over study. High-dose dexamethasone (DXM) (regimen A) was compared with the combination of DXM and high doses of metoclopramide (MCP) (regimen B). Five patients (20%) treated with regimen A and 13 (54%) treated with regimen B suffered neither nausea nor vomiting (P less than 0.05). Regimen B was found to be significantly more effective than regimen A for all the parameters of evaluation considered. No severe side-effects were observed.
