Doqualast is an antiasthmatic and antiallergic agent. It has a mode of antiallergic action similar to that of disodium cromoglycate and inhibits antigen-induced mediator release by interfering with the calcium transport required for histamine secretion across the mast cell membrane. In rabbits, no embryotoxic or teratogenic effects of doqualast were observed. The concomitant use of doqualast and theophylline might cause drug interaction. Doqualast is thought to increase the blood free fraction of concomitantly used theophylline and to accelerate elimination of theophylline from blood.
