ALTACE vs UNIRETIC
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Angiotensin-converting enzyme inhibitor; inhibits ACE, preventing conversion of angiotensin I to angiotensin II, reducing vasoconstriction and aldosterone secretion.
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.
2.5-5 mg orally once daily initially, titrated to 10-20 mg once daily; maximum 20 mg/day
1-2 tablets (each containing hydrochlorothiazide 25 mg and spironolactone 25 mg) orally once daily. Maximum dose: 4 tablets/day.

Ramiprilat: 13–17 hours (prolonged in renal impairment, up to 50 hours in severe renal insufficiency; multiple doses: 45–60 hours effective half-life due to tissue binding)
Terminal elimination half-life 13-17 hours; clinical context: supports once-daily dosing
Renal: 60% (30% as ramiprilat, 30% as metabolites); Fecal: 40% (unabsorbed drug and biliary metabolites)
Renal: 50-70% unchanged; biliary/fecal: 10-15% as metabolites
