CANDESARTAN CILEXETIL; HYDROCHLOROTHIAZIDE vs SALURON
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Candesartan cilexetil is a prodrug that is hydrolyzed to candesartan, an angiotensin II receptor blocker (ARB) that selectively antagonizes the AT1 receptor, inhibiting vasoconstriction and aldosterone secretion. Hydrochlorothiazide is a thiazide diuretic that inhibits the Na+/Cl- cotransporter in the distal convoluted tubule, reducing sodium and water reabsorption.
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 dose: 1 tablet (candesartan cilexetil 16 mg / hydrochlorothiazide 12.5 mg) orally once daily; titrate based on response to maximum dose of 32 mg/25 mg once daily.
Initial: 50-100 mg orally once daily; maintenance: 50-200 mg orally once daily or in divided doses.

Candesartan: ~9 hours (terminal); Hydrochlorothiazide: 6–15 hours (terminal). Both support once-daily dosing.
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).
Candesartan: 33% renal, 67% biliary/fecal. Hydrochlorothiazide: ≥95% renal (unchanged).
Primarily renal (≥95%) via glomerular filtration and tubular secretion; approximately 70% as unchanged drug, 25% as metabolites. Biliary/fecal excretion accounts for <5%.
