AMILORIDE HYDROCHLORIDE AND HYDROCHLOROTHIAZIDE vs HYDROPANE
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; inhibits sodium chloride cotransporter in distal convoluted tubule, increasing excretion of sodium and water, and reducing plasma volume.
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.
50–100 mg orally once daily, maximum 200 mg 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 8-15 hours in patients with normal renal function; may be prolonged in renal impairment.
Amiloride: 50% unchanged in urine, 40% in feces (biliary); Hydrochlorothiazide: >95% unchanged in urine.
Renal (approximately 50% as unchanged drug) and hepatic metabolism to inactive metabolites; fecal elimination accounts for about 10%.
