Acetylsalicylic acid (ASA) is a non-steroidal anti-inflammatory drug (NSAID) which inhibits cyclooxygenase 1 and 2 (COX-1 and COX-2). These two enzymes are involved in the synthesis of prostanoids (thromboxane A2, prostaglandins and prostacyclins). Additionally, the drug influences the production of lipoxins (LXA4, LXB4,
What is the mechanism of action of acetylsalicylic acid .
Oct 31, 2017· 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.
