Binds to rabbit platelet PAF receptors with high affinity. Inhibits PAF-induced platelet aggregation in rabbits (IC50=7.7 µM), bronchoconstriction in guinea-pigs, hypotension in rats and lethality in mice. Inhibits endotoxin-induced gastrointestinal damage (known to be due to PAF). Does not inhibit PAF-induced contraction of guinea pig lung parenchymal strips. Clinically useful spasmolytic agent for the control of increased tone or motility of the gut.
