We evaluated the antiemetic effect of zacopride, a potent 5-HT3-receptor antagonist with 5-HT4-receptor agonist properties, on delayed emesis caused by cisplatin (5 mg/kg, i.p.) in ferrets, compared with granisetron, a selective 5-HT3-receptor antagonist. Multiple intravenous injections of zacopride at 1 mg/kg, a dose that completely inhibited acute emesis caused bycisplatin (10 mg/kg, i.v.), significantly reduced delayed emesis. Granisetron (3.2 mg/kg) also reduced delayed emesis but this failed to reach statistical significance. The present study suggests that a combined 5-HT3-receptor antagonist/5-HT4-receptor agonist, like zacopride, may be useful against both acute and delayed emesis induced by cancer chemotherapy.
