Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Inhibits sodium-chloride symporter in the distal convoluted tubule of the nephron, reducing sodium reabsorption and increasing excretion of water, sodium, chloride, potassium, and hydrogen ions. Also causes vasodilation via direct arteriolar relaxation.
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.
Adults: 25-50 mg orally once daily initially, may increase to 100 mg daily in a single dose or two divided doses. Maximum dose: 100 mg/day.
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.

Clinical Note
moderateBenzthiazide + Mecamylamine
"The risk or severity of adverse effects can be increased when Benzthiazide is combined with Mecamylamine."
Clinical Note
moderateDexketoprofen + Benzthiazide
"The risk or severity of adverse effects can be increased when Dexketoprofen is combined with Benzthiazide."
Terminal elimination half-life: 8-12 hours; clinical context: supports once-daily dosing for hypertension, but duration of action may extend beyond half-life due to tissue distribution.
Candesartan: ~9 hours (terminal); Hydrochlorothiazide: 6–15 hours (terminal). Both support once-daily dosing.
Renal: ~90% (60% unchanged, 30% as glucuronide conjugate); biliary/fecal: minimal (<5%).
Candesartan: 33% renal, 67% biliary/fecal. Hydrochlorothiazide: ≥95% renal (unchanged).
