Vapiprost is a potent dicyclopentadiene thromboxane receptor antagonist that was being developed by Glaxo Wellcome in Japan. Vapiprost has been shown to be a potent and specific thromboxane (Tx)A2 receptor blocking drug in vitro using platelets and both vascular and airways smooth muscle preparations from different species. The drug is active in various experimental models of thrombosis. The potential clinical applications for a thromboxane receptor blocking drug include the treatment of thrombotic events and occlusive vascular disease. Phase III trials were underway in Japan for the treatment of deep vein thrombosis, which later were discontinued.

Sample Use Guides

In Vivo Use Guide

Vapiprost (GR32191) (80mg p.o.) caused a marked inhibition of PGD2 but not methacholine-induced bronchospasm in asthmatic subjects, and also caused a modest reduction in allergen-induced bronchospasm.

Route of Administration: Oral

In Vitro Use Guide

In in vitro experiments with human platelet, vapiprost inhibited the aggregation and ATP release stimulated with U-46619, collagen or arachidonic acid (AA) at an IC50 of less than 2.1 x 10(-8) M.
