| Use | Used as a weak diuretic |
| In vitro study | Amiloride is a relatively selective inhibitor of the epithelial sodium channel (ENaC), with IC 50 ranging from 0.1 μm to 0.5 μm. Amiloride is a relatively poor Na / H Exchanger (NHE) inhibitor, with IC50 as low as 3 μm at low external sodium ion concentrations and as high as 1 mM at high external sodium ion concentrations. Amiloride is a weak inhibitor of Na / Ca 2 Exchange (NCX) with IC 50 of 1 mM. Amiloride(1 μm) and Benzamil(30 nM) inhibit vasoconstriction, inhibiting myogenesis in response to increased perfusion pressure by blocking the activity of the ENaC protein. In vascular smooth muscle cells (VSMC), Amiloride completely inhibits sodium influx. |
| In vivo study | In DOCA salt hypertensive rats, Amiloride(1 mg/kg/day, subcutaneously) reversed the increase in initial collagen deposition and prevented further increases. In saline-drinking, stroke-prone spontaneously hypertensive rats (SHRSP), Amiloride delays the onset of proteinuria and improves brain and kidney histological scores. Compared with the control group. In hypertensive salt-dependent animals, Amiloride antagonizes or prevents the effects of aldosterone in these cells and in vascular and renal tissues. |
