Background

Amiloride is a potassium-sparing diuretic.^1,2 It is an inhibitor of the epithelial sodium channel (ENaC; K_0.5 = 2.6 µM for recombinant δENaC expressed in X. laevis oocytes).³ It inhibits sodium transport from bovine kidney cortex membrane vesicles with an IC₅₀ value of 0.4 µM.⁴ Amiloride inhibits the urokinase-type plasminogen activator (u-PA; K_i = 7 µM) and cardiac Na⁺/H⁺-ATPase (IC₅₀ = 83.8 µM).^5,6 It also inhibits calcium currents mediated by transient receptor potential polycystin 3 (TRPP3; IC₅₀ = 143 µM).⁷ Amiloride (30 mg/kg) reduces mean arterial pressure in spontaneously hypertensive, but not normotensive, rats.⁸ Formulations containing amiloride have been used alone, and in combination with thiazide diuretics, in the treatment of hypertension.
