Summary
Drospirenone has antimineralocorticoid activity and can raise serum potassium, while NSAIDs such as ketorolac can reduce renal potassium excretion through suppressed prostaglandin and renin effects. Together they may add to hyperkalemia risk, mostly in patients with renal impairment or other potassium-raising drugs. With intranasal dosing, systemic exposure is lower than with oral dosing but still meaningful.
What this interaction means in plain words
Drospirenone 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
Additive hyperkalemic effects from aldosterone antagonism (drospirenone) and NSAID-induced reduction in renal potassium excretion.
What to do
In patients with renal impairment or on other potassium-raising drugs, check serum potassium during the first treatment cycle and when NSAID use is prolonged. Limit ketorolac to the shortest course.
