FEXOFENADINE HYDROCHLORIDE ALLERGY vs TRINALIN
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.
TRINALIN is a combination of azatadine, a first-generation antihistamine that antagonizes histamine H1 receptors, and pseudoephedrine, a sympathomimetic amine that stimulates alpha-adrenergic receptors, causing vasoconstriction and reducing nasal congestion.
60 mg orally twice daily or 180 mg orally once daily.
One tablet (azatadine 1 mg/pseudoephedrine 120 mg) orally every 12 hours. Not to exceed 2 tablets in 24 hours.

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 approximately 20-30 hours; clinical context: allows twice-daily dosing for sustained decongestant effect
Primarily excreted unchanged in feces (80%) and urine (11%). Biliary excretion contributes to fecal elimination.
Renal: 70-80% as unchanged drug and metabolites; biliary/fecal: 20-30%
