Summary
Systemically absorbed aspirin may blunt the antihypertensive effect of atenolol and chlorthalidone, mainly at higher or repeated doses. Renal function may decline in volume-depleted patients receiving a diuretic.
What this interaction means in plain words
Aspirin rectal and Atenolol-chlorthalidone have a small, usually unimportant interaction. Most people can take both; the pharmacist may still mention it so that any unexpected effect is recognised.
Why it happens
