Forty chemotherapy-naive patients receiving high-dose cisplatin were included in a pilot study of a combination of ondansetron plus metoclopramide as antiemetic therapy. Patients received ondansetron 16 mg plus metoclopramide 0.5 mg/kg in 250 cm3 of normal saline i.v. 15 min before cisplatin administration on day 1; then ondansetron 8 mg was given orally b.i.d. and metoclopramide 0.5 mg/kg was given intramuscularly t.i.d. for 4 days. This combination was given to all patients receiving the first cycle of chemotherapy. ⋯ Although this study was not prospectively carried out in a randomized fashion, the results are not suggestive of a possible positive effect of metoclopramide addition to ondansetron. On the other hand, these results stress the role that corticosteroids may play in the control of delayed emesis. Toxicity was predictable and the frequency of side-effects was in the range reported in other studies with ondansetron.
