CANDESARTAN CILEXETIL; HYDROCHLOROTHIAZIDE vs HYDRO-D
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 sodium-chloride symporter (NCC) in the distal convoluted tubule, reducing sodium and water reabsorption and increasing potassium excretion.
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.
25-100 mg orally once daily in the morning.

Candesartan: ~9 hours (terminal); Hydrochlorothiazide: 6–15 hours (terminal). Both support once-daily dosing.
Terminal elimination half-life: 5.6 to 15 hours; prolonged in renal impairment and in patients with heart failure.
Candesartan: 33% renal, 67% biliary/fecal. Hydrochlorothiazide: ≥95% renal (unchanged).
Renal: approximately 50% as unchanged drug; biliary/fecal: approximately 50% as metabolites and minor unchanged drug.
