Summary
NSAIDs such as ketorolac can blunt the blood pressure lowering effect of beta-blockers, particularly with sustained use. Ketorolac also impairs renal function and may promote sodium and fluid retention, which can worsen hypertension or heart failure control. Nadolol is renally cleared, so reduced renal function may increase its exposure.
What this interaction means in plain words
Ketorolac intranasal and Nadolol 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
NSAID inhibition of renal and vascular prostaglandin synthesis causes sodium and water retention and opposes the antihypertensive effect of beta-blockers.
What to do
Monitor blood pressure and renal function if ketorolac is used for more than a few days. Limit the duration of NSAID therapy and adjust antihypertensive therapy if control is lost.
What to ask your pharmacist
- Should I take them at different times of day?
- Does the dose of either medicine need to change?
- Is there anything I should avoid, such as alcohol or certain foods, while on both?
