MAVIK vs QUINAPRIL HYDROCHLORIDE AND HYDROCHLOROTHIAZIDE
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Angiotensin-converting enzyme (ACE) inhibitor; inhibits ACE, preventing conversion of angiotensin I to angiotensin II, reducing vasoconstriction and aldosterone secretion, leading to decreased blood pressure and reduced cardiac workload.
Quinapril is an ACE inhibitor that inhibits the conversion of angiotensin I to angiotensin II, reducing vasoconstriction and aldosterone secretion; hydrochlorothiazide is a thiazide diuretic that inhibits sodium reabsorption in the distal convoluted tubule, increasing excretion of sodium and water.
Oral, 1-4 mg once daily for hypertension; 2-4 mg once daily for heart failure.
Initial: 10/12.5 mg (quinapril/hydrochlorothiazide) orally once daily. Titrate based on response to a maximum of 40/25 mg once daily.

Trandolaprilat: terminal half-life ~24 hours (range 15–35 hours) for once-daily dosing; effective half-life ~6–10 hours at steady state.
Quinaprilat terminal half-life ~25 hours (effective half-life ~12 hours); hydrochlorothiazide ~6-15 hours (increased in renal impairment).
Renal: trandolapril ~33% (as trandolaprilat and metabolites), trandolaprilat ~33% (as unchanged and metabolites); biliary/fecal: ~66% of total radioactivity.
Renal excretion of quinaprilat (active metabolite) ~50-60% unchanged; hydrochlorothiazide ~70% unchanged. Biliary/fecal elimination accounts for <10% for both components.
