Fabesetron (FK1052) (0.1 mg/kg p.o.) inhibits completely the increases in the colonic transit.FK1052 (100 μg/kg) completely prevents emesis induced by cisplatin (18 mg/kg, i.p.) in Suncus murinus.Animal Model:Male Sprague-Dawley rats weighing 220 to 330 g and male ddy mice weighing 25 to 35 g were used.
Dosage:0.1 mg/kg.
Administration:P.O.
Result:Significantly caused delay and its degree of inhibition was 33.8 ± 4.8% by 0.1 mg/kg p.o..

Dosage:1, 10, and 100 μg/kg.
