Summary
Ketorolac, even by the nasal route, is systemically absorbed and can reduce the antihypertensive effect of telmisartan. Together they raise the risk of acute kidney injury and hyperkalemia, especially in older or volume-depleted patients.
What this interaction means in plain words
Ketorolac intranasal and Telmisartan 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 vasodilatory renal prostaglandins reduces glomerular perfusion, which is critical when angiotensin II receptors are blocked, and potassium retention is additive.
What to do
Keep ketorolac courses short and ensure adequate hydration. Monitor blood pressure, serum creatinine and potassium during use.
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?
