ENALAPRIL MALEATE AND HYDROCHLOROTHIAZIDE vs NATURETIN-2.5
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Enalapril is an angiotensin-converting enzyme (ACE) inhibitor that inhibits the conversion of angiotensin I to angiotensin II, reducing vasoconstriction and aldosterone secretion, leading to decreased blood pressure. Hydrochlorothiazide is a thiazide diuretic that inhibits the sodium-chloride symporter in the distal convoluted tubule, increasing sodium, chloride, and water excretion, and reducing peripheral vascular resistance.
Bendroflumethiazide is a thiazide diuretic that inhibits the sodium-chloride symporter (NCC) in the distal convoluted tubule of the kidney, reducing sodium and chloride reabsorption and promoting diuresis.
Oral: Initially enalapril 5 mg and HCTZ 12.5 mg once daily; titrate to maximum enalapril 20 mg / HCTZ 25 mg once daily.
Hypertension: 2.5 mg orally once daily; may increase to 5 mg daily if needed. Edema: 2.5 to 10 mg orally once daily.

Enalaprilat: terminal 11 hours (multiple doses), prolonged in renal impairment (creatinine clearance <30 mL/min: 30-40 h). Hydrochlorothiazide: terminal 6-15 hours (mean 10 h), prolonged in renal impairment.
Terminal elimination half-life: 6-9 hours; prolonged in renal impairment and in elderly patients.
Enalapril: renal 60-80% (40-60% as enalaprilat, 20-40% as metabolites); fecal 20-40%. Hydrochlorothiazide: renal 95% (unchanged).
Renal excretion: approximately 95% as unchanged drug; biliary/fecal: <5%.
