title: Effect of BAY U 3405, a new thromboxane antagonist, on sudden death in rabbits.
abstract: We studied the effects of BAY U 3405 in experimental models of arachidonic acid- and collagen-induced sudden death. BAY U 3405 was effective in dose-dependently inhibiting death from both arachidonic acid and collagen at doses of 1, 3 and 10 mg/kg orally. The survival rate, usually amounting to less than 10% in vehicle-treated animals, was dramatically increased to 100% at the highest dose. The data obtained emphasize the role of thromboxane A2 as a mediator in this model, and the potential usefulness of BAY U 3405 for thromboembolic disorders.
