CHILDREN'S ALLEGRA HIVES vs HISPRIL
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Fexofenadine is a selective peripheral H1-receptor antagonist that blocks histamine-mediated effects, reducing pruritus and urticaria.
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.
Fexofenadine 180 mg orally once daily for adults and children 12 years and older.
10 mg orally once daily, increased to 20 mg once daily after 2-4 weeks if needed.

Terminal half-life: 14.4 hours; clinical context: supports twice-daily dosing in chronic urticaria
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.
Fecal (80% as unchanged drug); renal (15%, mostly as metabolites; <5% unchanged)
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%.
