HISPRIL vs LEVOCETIRIZINE HYDROCHLORIDE
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.
Levocetirizine is a selective peripheral histamine H1-receptor antagonist. It inhibits the effects of histamine at the H1 receptor, reducing allergic symptoms such as itching, sneezing, and rhinorrhea. It has lower affinity for central H1 receptors and anticholinergic properties compared to first-generation antihistamines.
10 mg orally once daily, increased to 20 mg once daily after 2-4 weeks if needed.
Oral, 5 mg once daily in the evening.

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: 7–8 hours in healthy adults; prolonged to 20–24 hours in renal impairment (CrCl <40 mL/min); clinically, stable levels require 2–3 days.
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%.
Approximately 85% renal excretion as unchanged drug via glomerular filtration and tubular secretion, 12.9% fecal excretion, <1% biliary.
