AMBODRYL vs FEXOFENADINE HYDROCHLORIDE ALLERGY
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Antihistamine (H1-receptor antagonist) with anticholinergic and sedative properties.
Fexofenadine is a selective peripheral H1-receptor antagonist that inhibits histamine release from mast cells and basophils.
10-20 mg intramuscularly or intravenously every 4-6 hours as needed, up to a maximum of 80 mg/day.
60 mg orally twice daily or 180 mg orally once daily.

Terminal elimination half-life 12-15 hours in adults; prolonged to 20-30 hours in hepatic impairment.
Terminal elimination half-life is 14.4 hours in healthy adults. In renal impairment, half-life may be prolonged up to 59 hours.
Primarily renal (70-80% as metabolites, 20-30% unchanged); biliary/fecal excretion accounts for 15-20%.
Primarily excreted unchanged in feces (80%) and urine (11%). Biliary excretion contributes to fecal elimination.
