ACCUPRIL vs UNIRETIC
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Angiotensin-converting enzyme (ACE) inhibitor; inhibits ACE, thereby blocking conversion of angiotensin I to angiotensin II, reducing vasoconstriction and aldosterone secretion, leading to decreased blood pressure.
Uniretic is a combination of an angiotensin-converting enzyme (ACE) inhibitor (moexipril) and a thiazide diuretic (hydrochlorothiazide). Moexipril inhibits ACE, preventing conversion of angiotensin I to angiotensin II, reducing vasoconstriction and aldosterone secretion. Hydrochlorothiazide inhibits sodium reabsorption in distal convoluted tubule, increasing excretion of sodium and water.
10-40 mg orally once daily; initial dose 10 mg, titrate to target dose based on blood pressure response; maximum 80 mg/day.
1-2 tablets (each containing hydrochlorothiazide 25 mg and spironolactone 25 mg) orally once daily. Maximum dose: 4 tablets/day.

Quinaprilat terminal elimination half-life is approximately 3 hours. In patients with renal impairment (CrCl <30 mL/min), half-life can be prolonged up to 10-25 hours, requiring dose adjustment.
Terminal elimination half-life 13-17 hours; clinical context: supports once-daily dosing
Primarily renal (about 60% as unchanged drug and 40% as metabolites, mainly quinaprilat), with biliary/fecal elimination accounting for less than 10%.
Renal: 50-70% unchanged; biliary/fecal: 10-15% as metabolites
