Prevention of delayed emesis with metoclopramide and dexamethasone in patients receiving moderately emetogenic cytotoxic treatment.
Forty-three untreated cancer patients receiving moderately emetogenic polychemotherapy entered a phase II trial in order to evaluate the effectiveness of the combination of metoclopramide (40 mg every 6 hrs) and dexamethasone (8 mg every 12 hrs) in the prevention of delayed emesis (days 2-3). For the control of acute emesis all patients received on day 1 ondansetron 8 mg for 3 times. Results of antiemetic treatment were as follows: complete/major protection from acute emesis (day 1) was observed in 72%/88% of patients. Worst day analysis of delayed emesis (days 2 and 3) showed that complete/major protection was obtained in 93%/95% of cases, respectively. Delayed nausea was not as well controlled: complete/major protection was observed in 44%/79% of patients. Extrapyramidal reactions occurred in 3 patients and moderate epigastric pain was reported by 3 patients. Since control of acute emesis could be one of the most important factors influencing delayed emesis, the absence of acute symptoms in 72% of our patients may be partially responsible for the excellent control of delayed emesis. The combination of metoclopramide and dexamethasone is a feasible and effective treatment for delayed emesis in outpatients receiving moderately emetogenic chemotherapy.
