Summary
Ephedrine has beta-2 agonist activity that can shift potassium into cells, whereas amiloride conserves potassium. The effects oppose each other and the net clinical impact is usually small. Ephedrine's pressor effect may also partly counter the blood pressure lowering of amiloride.
What this interaction means in plain words
Amiloride and Ephedrine have a small, usually unimportant interaction. Most people can take both; the pharmacist may still mention it so that any unexpected effect is recognised.
Amiloride belongs to Cardiovascular; Ephedrine belongs to Cardiovascular.
Why it happens
Beta-adrenergic stimulation increases cellular potassium uptake while amiloride reduces renal potassium loss; ephedrine's pressor effect also opposes antihypertensive action.
What to do
No routine action is needed; check serum potassium and blood pressure if ephedrine is used repeatedly or at high doses.
