CHILDREN'S CETIRIZINE HYDROCHLORIDE HIVES RELIEF vs TELDRIN
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Cetirizine is a selective histamine H1-receptor antagonist. It inhibits the H1 receptor, reducing histamine-mediated effects such as edema, flare, and pruritus.
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.
5 mg or 10 mg orally once daily; maximum 10 mg per day.
1-2 mg orally twice daily; maximum 4 mg/day.

Terminal elimination half-life is approximately 8.3 hours in healthy adults; prolonged to ~20 hours in renal impairment (CrCl <30 mL/min).
Terminal half-life: 9-12 hours (range 8-14) in healthy adults; prolonged in renal impairment.
Approximately 70% of the dose is excreted unchanged in urine via glomerular filtration and tubular secretion; about 10% is eliminated in feces.
Renal: 55-60% unchanged; fecal: 35-40%; minor biliary elimination.
