AY 25674 is an orally active antiallergic agent and a PDE inhibitor. AY 25674 inhibits the release of allergic histamine from mast cells. AY 25674 suppresses passive anaphylaxis induced by reaginic ( IgE ) antibodies. AY 25674 does not inhibit the increased vascular permeability caused by non-reaginic antibodies, serotonin or histamine. AY 25674 reaches its peak activity shortly after administration; rapid tolerance occurs at high doses. AY 25674 can be used in research related to passive anaphylaxis.
