Summary
NSAIDs such as ketorolac can reduce the antihypertensive effect of beta-blockers, particularly with sustained use. Ketorolac may also impair renal function. Short-term intranasal use carries a smaller risk.
What this interaction means in plain words
Betaxolol 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 renal prostaglandin synthesis causes sodium and fluid retention and offsets the blood pressure lowering of the beta-blocker.
What to do
Monitor blood pressure if ketorolac is used for more than a few days. Keep the course short and use the lowest effective dose.
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?
