Zacopride administered orally was more emetic in fed than in fasted ferrets. The emetic activity of zacopride (0.1 mg/kg p.o.) was inhibited (100%) by 0.1 mg/kg i.p. of zacopride and 1 mg/kg i.p. of ICS 205-930. Haloperidol (3.16 mg/kg i.p.) and prochlorperazine (3.16 mg/kg i.p.) were weakly effective. N-acetyl-5-hydroxytryptophyl-5-hydroxytryptophan amide, a 5-HT1Pantagonist, was inactive. Thus, the emetic activity of zacopride, like that of cisplatin, is blocked by 5-HT3receptor antagonists. © 1990.
