FEXOFENADINE HYDROCHLORIDE ALLERGY vs PROMETH PLAIN
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Fexofenadine is a selective peripheral H1-receptor antagonist that inhibits histamine release from mast cells and basophils.
Antagonist at histamine H1 receptors; also exhibits anticholinergic, antiemetic, and sedative effects.
60 mg orally twice daily or 180 mg orally once daily.
12.5-25 mg intramuscularly or intravenously every 4-6 hours as needed; maximum 100 mg/day.

Terminal elimination half-life is 14.4 hours in healthy adults. In renal impairment, half-life may be prolonged up to 59 hours.
Terminal elimination half-life is 10-14 hours in adults; may be prolonged in elderly or hepatic impairment.
Primarily excreted unchanged in feces (80%) and urine (11%). Biliary excretion contributes to fecal elimination.
Primarily renal (approximately 70%) as metabolites and unchanged drug; biliary/fecal excretion accounts for ~20%.
