DYAZIDE vs SALURON
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Dyazide is a combination of hydrochlorothiazide, a thiazide diuretic that inhibits the Na+/Cl- cotransporter in the distal convoluted tubule, reducing sodium and water reabsorption; and triamterene, a potassium-sparing diuretic that blocks epithelial sodium channels in the collecting duct, reducing potassium excretion.
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.
1-2 capsules orally once daily; each capsule contains hydrochlorothiazide 25 mg and triamterene 50 mg.
Initial: 50-100 mg orally once daily; maintenance: 50-200 mg orally once daily or in divided doses.

Triamterene: 1.5–2.5 hours; hydrochlorothiazide: 6–15 hours. Clinical dosing typically once daily.
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: triamterene ~80% (as metabolites and parent), hydrochlorothiazide >95% unchanged.
Primarily renal (≥95%) via glomerular filtration and tubular secretion; approximately 70% as unchanged drug, 25% as metabolites. Biliary/fecal excretion accounts for <5%.
