CHILDREN'S ALLEGRA HIVES vs TELDRIN
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.
TELDRIN contains loratadine and pseudoephedrine. Loratadine is a long-acting tricyclic antihistamine with selective peripheral H1-receptor antagonism. Pseudoephedrine is a sympathomimetic amine that acts as a decongestant by stimulating alpha-adrenergic receptors in the respiratory tract mucosa, causing vasoconstriction.
Fexofenadine 180 mg orally once daily for adults and children 12 years and older.
1-2 mg orally twice daily; maximum 4 mg/day.

Terminal half-life: 14.4 hours; clinical context: supports twice-daily dosing in chronic urticaria
Terminal half-life: 9-12 hours (range 8-14) in healthy adults; prolonged in renal impairment.
Fecal (80% as unchanged drug); renal (15%, mostly as metabolites; <5% unchanged)
Renal: 55-60% unchanged; fecal: 35-40%; minor biliary elimination.
