Summary
NSAIDs can blunt the blood-pressure-lowering effect of beta-blockers when used for more than a short period. Blood pressure control may worsen, particularly in patients with hypertension or reduced renal function.
What this interaction means in plain words
Atenolol and Meclofenamic acid 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.
Atenolol belongs to Cardiovascular; Meclofenamic acid belongs to Musculoskeletal.
Why it happens
NSAID inhibition of renal and vascular prostaglandin synthesis causes sodium and water retention and reduced vasodilation, opposing the antihypertensive effect.
What to do
Monitor blood pressure when the NSAID is started, changed or stopped, and use the lowest effective NSAID dose for the shortest time. Consider an alternative analgesic such as paracetamol if blood pressure rises.
