Abstract: We have investigated the effect of oxatomide, an antiallergic agent, on experimental allergic rhinitis in sensitized guinea pigs. Oxatomide (1 and 10 mg/kg, p.o.) significantly inhibited the sneeze response and nasal rubbing after antigen challenge. Oxatomide (10 and 30 mg/kg) reduced the increase in nasal vascular permeability induced by the antigen-antibody reaction. The decreases in nasal cavity volume caused by nasal mucosal swelling 10 min, 30 min and 6 hr after antigen challenge were significantly inhibited by oxatomide (30 mg/kg). These results indicate that oxatomide inhibits the experimental allergic rhinitis in guinea pigs.
