Summary
Ketorolac can impair renal function and potassium excretion, and with potassium citrate may lead to hyperkalemia. Risk is higher in dehydrated or renally compromised patients.
What this interaction means in plain words
Ketorolac and Potassium citrate 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.
Ketorolac belongs to Musculoskeletal; Potassium citrate belongs to Gastrointestinal Tract.
Why it happens
Prostaglandin inhibition reduces renal perfusion and aldosterone-mediated potassium excretion, adding to the supplemental load.

Check renal function and serum potassium, and limit ketorolac to short courses. Stop the potassium supplement or NSAID if hyperkalemia appears.
