Summary
Aspirin and clopidogrel inhibit platelets by different pathways and together increase bleeding, notably gastrointestinal. Rectal aspirin is absorbed systemically, so the effect applies, although dual therapy is often intentional after stenting or ACS.
What this interaction means in plain words
Aspirin rectal and Clopidogrel can affect each other. The combination is often manageable, but it may need a change of dose, a change of timing, or extra checks while both are taken.
Why it happens
Additive antiplatelet effect via COX-1 inhibition and P2Y12 receptor blockade.
What to do
Use only when dual antiplatelet therapy is indicated, with the shortest necessary duration and low-dose aspirin. Consider a proton pump inhibitor for GI protection and monitor for bleeding.
