Aspirin acts as an acetylating agent where an acetyl group is covalently attached to a serine residue in the active site of the COX enzyme. [1] This makes aspirin different from other NSAIDs (such as diclofenac and ibuprofen), which are reversible inhibitors; aspirin creates an allosteric change in the structure of the COX enzyme. [2]
Aspirin helps prevent blood clots from forming, which is the leading cause of heart attack and stroke, but the drug also carries a risk of bleeding. That risk can outweigh aspirin’s benefits in ...
The illustration shows how PAD can affect arteries in the legs. Figure A shows a normal artery with normal blood flow. The inset image shows a cross-section of the normal artery. Figure B shows an artery with plaque buildup that is partially blocking blood flow. The inset image shows a cross-section of the narrowed artery.
