Abstract;The inhibitory action of novel 5-HT3 receptor antagonist indisetron hydrochloride (indisetron) against the anticancer drug-induced emesis was examined in the various animals. Cisplatin, the anticancer drug, induced acute emesis in the dog (the dose of cisplatin was 3mg/kg), ferret (10mg/kg) and suncus (50mg/kg). Cisplatin at the low dose (5mg/kg) induced acute (0-24 hour) and delayed (24-72 hour) emesis in the ferret. The other anticancer drug, cyclophosphamide (200mg/kg) also induced acute emesis in the ferret. The inhibitory action of indisetron was examined in all these emesis models and compared with granisetron or ondansetron in some models. Indisetron (1mg/kg p.o.) inhibited the cisplatin-induced acute emesis in the dog, ferret and suncus. Granisetron inhibited the emesis in the dog with 0.3mg/kg p.o. but in the suncus with 10mg/kg p.o. Indisetron (1mg/kg s.c. twice per day) also suppressed the low dose cisplatin-induced emesis in the ferret for acute and delayed phase. Ondansetron (1mg/kg s.c. twice per day) did not suppress the cisplatin-induced emesis in the ferret for delayed phase but for acute phase. Indisetron (1mg/kg p.o.) inhibited the cyclophosphamide-induced emesis in the ferret. From these results, we found that indisetron ameliorate the anticancer drug-induced emesis at several animals in the same dosage. Indisetron may be a useful drug that prevent the anticancer drug-induced emesis in the chemotherapy. (author abst.)
