Repirinast is an orally-active antiallergic agent useful in the treatment of allergic asthma. Its activity is reportedly attributed to a metabolite, the corresponding free acid (MY-1250), which is 17 times more potent than disodium cromoglycate in inhibiting histamine release due to antigen-antibody reactions.
