DYAZIDE vs NATURETIN-2.5
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.
Bendroflumethiazide is a thiazide diuretic that inhibits the sodium-chloride symporter (NCC) in the distal convoluted tubule of the kidney, reducing sodium and chloride reabsorption and promoting diuresis.
1-2 capsules orally once daily; each capsule contains hydrochlorothiazide 25 mg and triamterene 50 mg.
Hypertension: 2.5 mg orally once daily; may increase to 5 mg daily if needed. Edema: 2.5 to 10 mg orally once daily.

Triamterene: 1.5–2.5 hours; hydrochlorothiazide: 6–15 hours. Clinical dosing typically once daily.
Terminal elimination half-life: 6-9 hours; prolonged in renal impairment and in elderly patients.
Renal: triamterene ~80% (as metabolites and parent), hydrochlorothiazide >95% unchanged.
Renal excretion: approximately 95% as unchanged drug; biliary/fecal: <5%.
