ACCURETIC vs MAVIK
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
ACCURETIC is a combination of quinapril, an angiotensin-converting enzyme (ACE) inhibitor, and hydrochlorothiazide, a thiazide diuretic. Quinapril inhibits ACE, preventing conversion of angiotensin I to angiotensin II, reducing vasoconstriction and aldosterone secretion. Hydrochlorothiazide inhibits sodium reabsorption in the distal convoluted tubule, increasing diuresis and lowering blood pressure.
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.
One tablet orally once daily. Initial dose is 20 mg quinapril/12.5 mg hydrochlorothiazide, titrated to maximum 20 mg quinapril/25 mg hydrochlorothiazide.
Oral, 1-4 mg once daily for hypertension; 2-4 mg once daily for heart failure.

Quinapril: 0.8 hours; Quinaprilat (active): 2 hours in young healthy adults, prolonged to 3-4 hours in elderly or renal impairment.
Trandolaprilat: terminal half-life ~24 hours (range 15–35 hours) for once-daily dosing; effective half-life ~6–10 hours at steady state.
Renal: approximately 90% (60% unchanged, 30% as metabolites). Fecal/biliary: <10%.
Renal: trandolapril ~33% (as trandolaprilat and metabolites), trandolaprilat ~33% (as unchanged and metabolites); biliary/fecal: ~66% of total radioactivity.
