Abstract
The intravenous administration of arachidonic acid to rabbits is an effective in vivo model for evaluating potential anti-thrombotic drugs. Most of the non-steroidal antiinflammatory agents (NSAIFA) inhibit this arachidonic acid induced mortality (except sodium salicylate and acetaminophen). However, there is a lack of correlation between the relative potencies from various assays (rabbit antithrombotic, anti-inflammatory, alalgesic, ulcerogenic and inhibition of prostaglandin synthetase evaluations). These studies imply other actions with NSAIFA than an effect solely on the prostaglandin biosynthetic pathway.
