CHILDREN'S FEXOFENADINE HYDROCHLORIDE ALLERGY vs HISPRIL
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Fexofenadine is a selective peripheral H1-receptor antagonist. It inhibits histamine release from mast cells and basophils, reducing allergic symptoms.
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 hydrochloride 60 mg orally twice daily or 180 mg orally once daily.
10 mg orally once daily, increased to 20 mg once daily after 2-4 weeks if needed.

14.4 hours (range 11-16 hours) in healthy adults; prolonged in renal impairment.
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.
Primarily fecal (80%) and renal (11%) as unchanged drug.
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%.
