HISPRIL vs ZADITOR
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
HISPRIL (lisinopril) is an angiotensin-converting enzyme (ACE) inhibitor that blocks the conversion of angiotensin I to angiotensin II, reducing vasoconstriction and aldosterone secretion, leading to decreased blood pressure and afterload.
Selective histamine H1 receptor antagonist. Stabilizes mast cells, reducing release of histamine and other mediators of allergic response.
10 mg orally once daily, increased to 20 mg once daily after 2-4 weeks if needed.
1 drop in each affected eye twice daily, approximately 6-8 hours apart.

The terminal elimination half-life of HISPRIL is approximately 12-15 hours in patients with normal renal function, supporting twice-daily dosing. In moderate to severe renal impairment (CrCl <30 mL/min), half-life is prolonged up to 30-40 hours, necessitating dose interval adjustment.
Terminal elimination half-life is approximately 7 hours in adults, which supports twice-daily dosing for sustained ocular effects.
HISPRIL is predominantly excreted renally, with approximately 60-70% of an administered dose recovered unchanged in urine over 48 hours. Hepatic metabolism accounts for <10% of elimination, and fecal excretion contributes <5%.
Primarily renal excretion as unchanged drug (approximately 30-40% of dose) and biliary/fecal elimination of metabolites (60-70%).
