Effects of the "vascular factor" on platelet and vascular arachidonic acid metabolism in man.

The effects of a drug with hemostatic action, "Vascular Factor" (V.F.), on platelet and vascular arachidonic acid metabolism were evaluated in man to establish the lack of side effects on platelet aggregation. Plasma levels of 6-keto PGF1 alpha and thromboxane B2 were determined by RIA in healthy volunteers undergoing treatment with V.F. Results indicate that basal values obtained in these compounds do not present significant variations following treatment with V.F. On the basis of these results, the possibility of administering this drug in atherosclerotic patients is further confirmed.
