Azelastine, a new antiallergic/antiasthmatic agent, inhibits PAF-acether-induced platelet aggregation, paw edema and bronchoconstriction.
Azelastine is a phthalazinone derivative with a wide spectrum of pharmacologically relevant activities. Since PAF-acether has been considered to be a potent mediator of asthma, azelastine was assayedExpand
