Summary

Ketorolac is an NSAID, and systemic absorption from the nasal route can still reduce renal prostaglandin synthesis. With triamterene this can cause hyperkalemia and acute kidney injury, and NSAIDs may also blunt diuretic effect.

What this interaction means in plain words

Ketorolac intranasal and Triamterene 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.

Evidence level: Moderate

Why it happens

Inhibition of renal prostaglandins reduces renin-aldosterone activity and renal perfusion, compounding triamterene's potassium retention.

What to do

Limit ketorolac to the shortest course and avoid in renal impairment or dehydration. Monitor serum potassium and creatinine during combined use.
