CANDESARTAN CILEXETIL; HYDROCHLOROTHIAZIDE vs DIUCARDIN
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.
Thiazide diuretic that inhibits the Na+/Cl- symporter in the distal convoluted tubule, reducing sodium and chloride reabsorption, leading to increased diuresis and vasodilation.
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.
Hydrochlorothiazide 25-50 mg orally once daily, titrated based on response. Maximum dose 100 mg/day.

Candesartan: ~9 hours (terminal); Hydrochlorothiazide: 6–15 hours (terminal). Both support once-daily dosing.
Terminal elimination half-life is approximately 18-24 hours in normal renal function. This prolongs significantly in renal impairment, requiring dose adjustment.
Candesartan: 33% renal, 67% biliary/fecal. Hydrochlorothiazide: ≥95% renal (unchanged).
Primarily renal excretion: approximately 60-70% of the dose is excreted unchanged in urine within 24 hours. Biliary/fecal elimination accounts for about 20-30%, with some enterohepatic circulation.
