ACEON vs PRINZIDE
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.
PRINZIDE is a combination of lisinopril (an ACE inhibitor) and hydrochlorothiazide (a thiazide diuretic). Lisinopril inhibits angiotensin-converting enzyme, reducing angiotensin II formation, leading to vasodilation and decreased aldosterone secretion. Hydrochlorothiazide inhibits sodium and chloride reabsorption in the distal convoluted tubule, promoting diuresis and reducing plasma volume.
Initial: 4 mg orally once daily; titrate to 8-32 mg daily in 1-2 divided doses. Typical maintenance: 8-16 mg daily.
Oral, 1-2 tablets daily; each tablet contains 25 mg hydrochlorothiazide and 5 mg lisinopril. Adjust based on blood pressure response; maximum daily dose: 2 tablets.

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.
Lisinopril: terminal half-life 12 hours (effective half-life 30 hours due to prolonged ACE binding). Hydrochlorothiazide: terminal half-life 6-15 hours (biphasic, initial phase 2-4 h, terminal phase 6-15 h) with prolonged terminal phase in renal impairment.
Renal: approximately 30% as perindopril and 20% as perindoprilat; fecal: approximately 50% as metabolites.
Lisinopril is excreted unchanged in urine (100% renal elimination); hydrochlorothiazide is excreted 95% renally as unchanged drug and 5% via bile.
