Summary
NSAIDs such as ketorolac can blunt the antihypertensive effect of beta-blockers and diuretics. Through renal prostaglandin inhibition they can also reduce the diuretic effect and add to the risk of acute kidney injury in volume-depleted patients. Short-term intranasal use carries a lower risk than prolonged systemic use, but systemic absorption is meaningful.
What this interaction means in plain words
Atenolol-chlorthalidone and Ketorolac intranasal 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
Inhibition of prostaglandin synthesis causes sodium and fluid retention and reduces renal blood flow, opposing antihypertensive and diuretic effects.
What to do
Keep the NSAID course short and monitor blood pressure and renal function. Ensure adequate hydration and consider an alternative analgesic if blood pressure rises.
