Ondansetron plus dexamethasone in the control of high dose cisplatin-induced emesis.

Twenty-two patients who underwent chemotherapy with cisplatin (CDDP) at doses > 100 mg/m2 also received antiemetic treatment comprised of the combination of ondansetron plus dexamethasone. The results obtained have shown a good activity from this combination with these high doses of CDDP, with a response of 81.8% (complete+major protection). There were also three therapeutic failures in patients with a few negative prognostic characteristics. It is our intention to use a benzodiazepine and adequate psychological support in an attempt to increase the response percentages in these kinds of patients.
