We investigated the effect of IPD-1151T (Suplatast Tosilate, (+/-)-[2-[4-(3-ethoxy-2-hydroxypropoxy) phenyl-carbamoyl]-ethyl] dimethylsulfonium p-toluenesulfonate) against allergic bronchoconstriction induced by allergen and methacholine (MCh).BALB/c mice were sensitized by intraperitoneal injection of 0.5 microgram of keyhold limpet hemocyanin mixed with Al(OH)3. IPD-1151T was administered orally once a day for 5 or 14 days in doses of 10, 30 or 100 mg/kg body weight. Bronchoconstriction was measured 24 hrs after the final drug administration. IPD-1151T inhibited both antigen-mediated allergic bronchoconstriction and induction of bronchial hyperresponsiveness after sensitization or allergen challenge in actively sensitized mice. The degree of inhibition was proportional to the dose and frequency of oral administration of the agent.

D016535 Bronchial Hyperreactivity Tendency of the smooth muscle of the tracheobronchial tree to contract more intensely in response to a given stimulus than it does in the response seen in normal individuals. This condition is present in virtually all symptomatic patients with asthma. The most prominent manifestation of this smooth muscle contraction is a decrease in airway caliber that can be readily measured in the pulmonary function laboratory.
