ACEON vs UNIRETIC
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
ACEON (perindopril) is an angiotensin-converting enzyme (ACE) inhibitor. It inhibits ACE, which converts angiotensin I to angiotensin II, a potent vasoconstrictor. This results in decreased vasopressor activity, reduced aldosterone secretion, and lower peripheral vascular resistance, leading to antihypertensive effects.
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.
Initial: 4 mg orally once daily; titrate to 8-32 mg daily in 1-2 divided doses. Typical maintenance: 8-16 mg daily.
1-2 tablets (each containing hydrochlorothiazide 25 mg and spironolactone 25 mg) orally once daily. Maximum dose: 4 tablets/day.

Perindoprilat: terminal half-life ~30 hours (up to 120 hours in elderly or heart failure due to prolonged terminal phase from slow dissociation from ACE binding); perindopril: ~1.5 hours.
Terminal elimination half-life 13-17 hours; clinical context: supports once-daily dosing
Renal: approximately 30% as perindopril and 20% as perindoprilat; fecal: approximately 50% as metabolites.
Renal: 50-70% unchanged; biliary/fecal: 10-15% as metabolites
