CANDESARTAN CILEXETIL AND 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 AT1 receptors, leading to vasodilation, reduced aldosterone secretion, and decreased blood pressure. Hydrochlorothiazide is a thiazide diuretic that inhibits sodium and chloride reabsorption in the distal convoluted tubule, promoting diuresis and further lowering blood pressure.
Thiazide diuretic that inhibits the sodium-chloride symporter (NCC) in the distal convoluted tubule, reducing sodium and water reabsorption and increasing potassium excretion.
1 tablet (candesartan cilexetil 16 mg/hydrochlorothiazide 12.5 mg) orally once daily. Maximum dose: 1 tablet (32 mg/25 mg) once daily.
25-100 mg orally once daily in the morning.

Candesartan: Terminal t1/2 ~9 hours (linear); clinically, once-daily dosing provides 24-hour antihypertensive effect. Hydrochlorothiazide: Terminal t1/2 ~6-15 hours (averaging 10 hours), prolonged in renal impairment.
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 as unchanged drug and inactive metabolites. Hydrochlorothiazide: ≥95% renal as unchanged drug.
Renal: approximately 50% as unchanged drug; biliary/fecal: approximately 50% as metabolites and minor unchanged drug.
