Triflusal is an antiplatelet agent structurally related to the salicylate group of compounds, but it is not derived from aspirin (acetylsalicylic acid). Platelet antiaggregant properties of triflusal and its active 3-hydroxy-4-trifluoro-methylbenzoic acid metabolite are primarily mediated by specific inhibition of platelet arachidonic acid metabolism. Triflusal, compared with placebo for 6 months, significantly reduced the incidence of nonfatal myocardial infarction in patients with unstable angina. In patients with peripheral arteriopathy, total and pain free walking distances were markedly improved in triflusal compared with placebo recipients. The cumulative event rate for stroke, ischemic cardiopathy and vascular death was lower, but not significantly different, in patients with atherothrombotic stroke who received triflusal than in aspirin recipients. Differences were significant, and favoured triflusal, in a subgroup of patients with > 70% carotid stenosis. Prophylaxis with triflusal for 6 months after aortocoronary vein grafting reduced the number of new distal anastomosis occlusions and the graft attrition rate more than aspirin or placebo. The incidence of deep vein thrombosis or pulmonary embolism in more than 500 patients undergoing hip surgery was similar for these 3 treatments. The amount of blood transfused was significantly reduced in triflusal compared with aspirin recipients who underwent hip surgery. Risk of haemorrhage was also reduced in ischemic stroke patients receiving triflusal versus aspirin.
