CANDESARTAN CILEXETIL; HYDROCHLOROTHIAZIDE vs DIURIL
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.
Inhibits sodium reabsorption in the distal convoluted tubule by blocking the sodium-chloride symporter, leading to increased excretion of sodium, chloride, and water.
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.
Adults: 500 mg to 1000 mg orally once or twice daily; maximum 2000 mg per day.

Candesartan: ~9 hours (terminal); Hydrochlorothiazide: 6–15 hours (terminal). Both support once-daily dosing.
Terminal elimination half-life is 6-15 hours (mean 10 hours). In renal impairment, half-life can exceed 24 hours.
Candesartan: 33% renal, 67% biliary/fecal. Hydrochlorothiazide: ≥95% renal (unchanged).
Primarily renal (90-95% excreted unchanged via glomerular filtration and tubular secretion); minimal biliary/fecal (<5%).
