ENALAPRIL MALEATE AND HYDROCHLOROTHIAZIDE vs HYDRO-RIDE
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.

Oral: Initially enalapril 5 mg and HCTZ 12.5 mg once daily; titrate to maximum enalapril 20 mg / HCTZ 25 mg once daily.
Initiate at 12.5-25 mg orally once daily. Titrate to 50-100 mg once daily. Maximum 200 mg per day.

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 half-life 4-6 hours (prolonged in renal impairment).
Enalapril: renal 60-80% (40-60% as enalaprilat, 20-40% as metabolites); fecal 20-40%. Hydrochlorothiazide: renal 95% (unchanged).
Primarily renal (50% unchanged; remainder as glucuronide conjugate); biliary/fecal <10%.
