Abstract
The last 35 years of clinical research on aspirin have proven its value as a lifesaving drug for the treatment and prevention of atherothrombosis. The place of low-dose aspirin in the therapeutic armamentarium has not been substantially altered by the successful development of new antiplatelet agents, including P2Y12 and PAR-1 receptor blockers. The demonstration of additive beneficial effects resulting from effective blockade of the platelet ADP and/or thrombin receptor combined with thromboxane suppression in high-risk patients is consistent with the multifactorial nature of atherothrombosis. Besides becoming an essential component of the antithrombotic strategy in high-risk settings, low-dose aspirin has also provided a mechanistic insight into the participation of platelets in other pathophysiologic processes, including colorectal cancer. The aim of this chapter is to review the mechanism of action and clinical pharmacology of aspirin as an antiplatelet agent, as well as the randomized trial evidence supporting its efficacy and safety. Moreover, more recent findings on additional long-term benefits of aspirin therapy will be discussed and new developments put into perspective.
