Summary WEB 2086 is a novel PAF-acether antagonist, whose pharmacological action in man has only been preliminarily defined. Twelve healthy male volunteers received oral doses of 5, 30 and 90 mg and over the following 24 h inhibition of 5 × 10−8 M PAF-acether-induced platelet aggregation ex vivo was studied as an indicator of pharmacological activity. WEB 2086 inhibited PAF-acether-induced platelet aggregation in all the doses tested, with the maximum effect 1 to 2 h after administration. After 2 h 5- 30- and 90-mg doses caused, respectively, 87, 98 and 100% inhibition. The magnitude and duration of the inhibitory effect was dose-dependent, with a significant action still detectable 10 h after administration of all three doses, and 12 h after administration of the two highest doses (30 and 90 mg). The subjects did not complain of any significant adverse effect and all completed the study.
