Aspirin is one of the oldest and most commonly used nonprescription drugs in the world. Although commonly it is used for relief from common headache and muscular pain, its use in the prevention and treatment of platelet related complications in cardiovascular diseases (CVD) and cerebrovascular disease (CBVD) is quite controversial. A brief review of the major aspirin trials indicated that a full strength aspirin taken daily had no significant beneficial effect in reducing mortality of patients with CVD/CBVD. However, two major trials (ISIS-2, PHS) in which either low dose aspirin (160 mg) or one aspirin administered every other day, have demonstrated significant reduction in fatal and nonfatal cardiovascular events. Even a dose as low as 1 mg aspirin per day significantly lowers platelet thromboxane synthesis. As a result of these studies, low dose aspirin should be the choice of prophylactic therapy aimed at the inhibition of platelet cyclooxygenase activity. Controlled-release low dose aspirin may favorably reduce platelet thromboxane production and spare vascular prostacyclin synthesis. At least 100 mgs of aspirin per day are essential to completely inhibit steady state thromboxane formation. Low dose aspirin (160 mgs) has been shown to be as effective as the full strength aspirin (325 mgs) in reducing clinical complications related to platelet activation. The antithrombotic effect of aspirin is well established and improved formulations, well thought out therapeutic protocols, customized dosage, appropriate timing of delivery, a better understanding of platelet function and pathophysiology of CUD/CBUD will facilitate maximization of the beneficial effects of aspirin.
