Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Hydrochlorothiazide is a thiazide diuretic that inhibits the sodium-chloride symporter (NCC) in the distal convoluted tubule of the nephron, reducing sodium and chloride reabsorption, leading to increased diuresis, decreased plasma volume, and vasodilation. It also reduces peripheral vascular resistance.
Saluron (hydroflumethiazide) is a thiazide diuretic that inhibits the sodium-chloride symporter (NCC) in the distal convoluted tubule of the nephron, increasing excretion of sodium, chloride, and water. It also reduces peripheral vascular resistance through direct vasodilatory effects.
Initial: 25 mg orally once daily; may increase to 50 mg once daily after 2 weeks based on response. Maximum: 50 mg daily.
Initial: 50-100 mg orally once daily; maintenance: 50-200 mg orally once daily or in divided doses.

Terminal elimination half-life is 8-12 hours in adults with normal renal function; extended to 20-30 hours in severe renal impairment (CrCl <30 mL/min).
Terminal elimination half-life is 8-12 hours in adults with normal renal function; prolonged in renal impairment (up to 24-36 hours with creatinine clearance <30 mL/min).
Renal excretion of unchanged drug accounts for 60% of elimination; biliary/fecal excretion accounts for 30%; 10% metabolized.
Primarily renal (≥95%) via glomerular filtration and tubular secretion; approximately 70% as unchanged drug, 25% as metabolites. Biliary/fecal excretion accounts for <5%.
