title: An open randomised cross-over study on granisetron versus ondansetron in the prevention of acute emesis induced by moderate dose cisplatin-containing regimens.
abstract: The aim of the study was to compare granisetron (GRA) with ondansetron (OND) in the prevention of acute emesis in consecutive chemotherapy-naive patients admitted to our department to receive a cytotoxic treatment containing cisplatinum (CP) at a dose > or = 50 mg/m2. Eligible patients were randomised at their first cycle to receive either OND or GRA with cross-over of the anti-emetic treatment on the second cycle. The cytotoxic treatments included five different multidrug regimens containing CP (median dose 60 mg/m2, range 50-70 mg/m2) administered on day 1 and repeated every 21-28 days. OND was administered at the dose of 8 mg x 3 i.v. on day 1 and 8 mg x 2 orally on day 2. GRA was always administered at the dose of 3 mg i.v. on day 1. 124 patients entered the study. 58 patients received OND at their first cycle and 66 received GRA. Complete protection of acute emesis with OND and GRA was observed, with the first and second cycles combined as follows: nausea 53 and 60%, vomiting 68 and 71%, respectively (no statistically significant difference). The cross-over analysis comprising 101 patients confirmed no difference between the two anti-emetic treatments. 21 patients (19%) on OND and 14 patients (12%) on GRA suffered headaches (P = 0.15). 25 (25%) patients preferred OND, 45 (45%) preferred GRA, while 31 (30%) expressed no preference (P = 0.003). However, these differences also depended on the sequence of anti-emetics in the cross-over. In conclusion, in this study, a single dose of GRA is demonstrated to be as effective as multiple doses of OND in the prevention of acute emesis.
