title: WEB 2086. A potent PAF antagonist exerts protective effect toward PAF-induced gastric damage.
abstract: Single intravenous administration of platelet activating factor (PAF; 4 micrograms/kg) induced reproducible gastric damage in the conscious rat which was prevented by WEB 2086, a potent and specific PAF-antagonist. Intravenous and oral ED50s in protecting rats from gastric damage were 61 and 633 micrograms/kg, respectively. Because of the reported association between septic shock and gastrointestinal ulceration, the therapeutic potential of PAF-antagonists might be broader than previously thought.
