[The effect of KW-4679, an antiallergic drug, on experimental allergic rhinitis].
Effect of KW-4679, an antiallergic agent, on the experimental allergic rhinitis was studied in guinea pigs. 1) KW-4679 inhibited the sneeze response and the nasal rubbing induced after the intranasal administration of antigen in sensitized guinea pigs. The inhibitions were dose-related and significant at 0.03 mg/kg p.o. for sneeze response and 1 mg/kg p.o. for nasal rubbing, respectively. 2) The nasal vascular permeability was increased after the intranasal administration of antigen in sensitized guinea pigs. KW-4679 significantly reduced the increase of the nasal vascular permeability at 1 mg/kg p.o. or higher. From these results, KW-4679 may have inhibitory effects on sneeze, nasal irritation and rhinorrhea in clinical use.
