TELMISARTAN AND HYDROCHLOROTHIAZIDE vs TEVETEN HCT
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Telmisartan is an angiotensin II receptor blocker (ARB) that selectively inhibits the binding of angiotensin II to the AT1 receptor, leading to vasodilation and reduced aldosterone secretion. Hydrochlorothiazide is a thiazide diuretic that inhibits the sodium-chloride symporter in the distal convoluted tubule, increasing excretion of sodium and water.
TEVETEN HCT combines eprosartan mesylate, an angiotensin II receptor antagonist, and hydrochlorothiazide, a thiazide diuretic. Eprosartan blocks the vasoconstrictor and aldosterone-secreting effects of angiotensin II by selectively antagonizing the AT1 receptor. Hydrochlorothiazide inhibits the sodium-chloride symporter in the distal convoluted tubule, increasing excretion of sodium, chloride, and water, thereby reducing plasma volume.
Oral, one tablet once daily. Initial: Telmisartan 40 mg/HCTZ 12.5 mg; titrate to max 80 mg/25 mg once daily.
One tablet orally once daily, containing eprosartan 600 mg and hydrochlorothiazide 12.5 mg or 25 mg, with or without food. Maximum dose: eprosartan 600 mg/hydrochlorothiazide 25 mg per day.

Telmisartan: 24 hours (terminal); supports once-daily dosing with ~3-5 days to steady state. Hydrochlorothiazide: 6-15 hours (mean 10h); prolonged in renal impairment.
Eprosartan: 5-9 hours; Hydrochlorothiazide: 6-15 hours; allows once-daily dosing.
Telmisartan: >99% biliary-fecal as unchanged drug, <2% renal. Hydrochlorothiazide: ≥95% renal as unchanged drug; minimal biliary.
Eprosartan: renal (70% unchanged, 10% as metabolite), biliary/fecal (20%); Hydrochlorothiazide: renal (≥95% unchanged).
