✦ Synopsis

The effects of aspirin, nifedipine, dipyridamole and cavinton on platelet aggregability in patients with atherosclerosis has been studied using various agents to induce aggregation. The drugs reduced platelet aggregability when aggregation was induced by ADP, adrenaline, or collagen alone. However, if platelet aggregation were induced by combinations of the agonists (including combinations of ADP with either adrenaline or platelet-activating factor (PAF), adrenaline with PAF, and collagen with ADP), the anti-aggregant effects of aspirin, dipyridamole, and cavinton were significantly reduced. The effect of nifedipine was less markedly reduced, especially by combinations which included adrenaline. The data suggest that positive agonist interactions may lead to a reduction in the therapeutic activity of antiplatelet drugs.

There is ample evidence to suggest that hematogenous metastasis may be related to the ability of tumor cells to promote aggregation of host platelets. Arachidonic acid metabolism in platelets and vessel walls may also contribute to the metastatic process. Several preliminary trials of platelet inhib
