AMILORIDE HYDROCHLORIDE AND HYDROCHLOROTHIAZIDE vs NATURETIN-5
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Amiloride is a potassium-sparing diuretic that blocks epithelial sodium channels (ENaC) in the distal convoluted tubule and collecting duct, inhibiting sodium reabsorption and reducing potassium excretion. Hydrochlorothiazide is a thiazide diuretic that inhibits the sodium-chloride cotransporter (NCC) in the distal convoluted tubule, increasing sodium, chloride, and water excretion.
Thiazide diuretic that inhibits sodium-chloride symporter in distal convoluted tubule, decreasing sodium and water reabsorption and reducing intravascular volume and blood pressure.
One tablet (amiloride 5 mg/hydrochlorothiazide 50 mg) orally once daily initially, increased if needed to twice daily. Maximum dose: amiloride 10 mg/hydrochlorothiazide 100 mg daily.
5 mg orally once daily.

Amiloride: 6-9 hours (prolonged in renal impairment); Hydrochlorothiazide: 6-15 hours (prolonged in renal impairment, heart failure).
Terminal elimination half-life is approximately 18-24 hours; clinically, this supports once-daily dosing and requires renal function monitoring.
Amiloride: 50% unchanged in urine, 40% in feces (biliary); Hydrochlorothiazide: >95% unchanged in urine.
Primarily renal (70-80% as unchanged drug); the remainder (20-30%) is eliminated via biliary/fecal routes.
