Mechanism of action
Directly blocks epithelial sodium channels (ENaC) in the distal nephron, reducing sodium reabsorption and decreasing potassium and hydrogen ion secretion.
Side effects & warnings
Hyperkalemia risk. Weak diuretic alone — usually combined with thiazide or loop diuretic. Avoid in severe renal impairment.

Amiloride dosing in other species
Why a species-specific page? Amiloride pharmacokinetics differ across species: dose ranges, intervals, and route preferences are not interchangeable. Cross-extrapolation from canine doses is unsafe in cat — the rules above are the citations specific to this species, not generic recommendations.
