The anti-inflammatory mechanism of aspirin is due to its irreversible inhibition of cyclooxygenases (COX-1 & -2). COX is involved in the inflammation cascade (see diagram below) that converts arachidonic acid (formed by the action of phospholipase... Aspirin. Aspirin is used for prophylaxis of TIA and/or stroke except in patients with an allergy to aspirin or salicylates.

  • and Mechanism of Action Aspirin, otherwise known as acetylsalicylic acid, acts by acetylation of the two isoenzyme forms of prostaglandin G/H synthase. This results in the irreversible inactivation of the cyclooxygenase activity of this enzyme, preventing the conversion of arachidonic acid to prostaglandin G 2, and consequently decreasing 1. Early explanations for the action of aspirin. Before 1971, little was known about the real mechanism of action of aspirin-like drugs. They produced an anti-inflammatory effect that was qualitatively and quantitatively different from that of the anti-inflammatory steroids, and their analgesic action was of a different nature than that

    Soon after, other drugs having similar actions to aspirin were discovered, and the group was termed the “aspirin-like drugs” (also now termed the nonsteroidal anti-inflammatory drugs [NSAIDs]). Twenty-five years ago, it was proposed that the mechanism of action of NSAIDs was through their inhibition of prostaglandin biosynthesis. Although no exact mechanism has been entirely proposed so far to explain the antineoplastic effect of aspirin against cancer, two mechanisms have been under focus, the first is related to its anti

Non-steroidal anti-inflammatory drugs (NSAIDs) and their NO derivatives (NO-NSAIDs), and synthetic analogs are highly effective as anticancer agents that exhibit relatively low toxicity compared to most clinically used drugs. However, the mechanisms of action for NSAIDs and NO-NSAIDs are not well defined and this has restricted their, Taken together, our article describes a novel mechanism of action for anti-tumor activity of aspirin and implicates aspirin as a novel agent for cervical cancer.
