CANDESARTAN CILEXETIL; HYDROCHLOROTHIAZIDE vs ENDURONYL FORTE
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.
Enduronyl Forte is a combination of methyclothiazide, a thiazide diuretic that inhibits the sodium-chloride symporter (NCC) in the distal convoluted tubule, and deserpidine, a Rauwolfia alkaloid that depletes catecholamines from adrenergic nerve endings, resulting in reduced peripheral vascular resistance and CNS sedation.
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.
Oral: Initial 2.5-5 mg once daily; increase as needed to maximum 20 mg once daily.

Candesartan: ~9 hours (terminal); Hydrochlorothiazide: 6–15 hours (terminal). Both support once-daily dosing.
Terminal elimination half-life: 24-48 hours (avg. 36 h); due to long half-life, requires caution in renal impairment.
Candesartan: 33% renal, 67% biliary/fecal. Hydrochlorothiazide: ≥95% renal (unchanged).
Renal: ~50% unchanged; Biliary/Fecal: ~50% as metabolites and unchanged drug.
