CHILDREN'S CETIRIZINE HYDROCHLORIDE ALLERGY vs TELDRIN
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Cetirizine is a selective antagonist of peripheral histamine H1 receptors. It inhibits the H1 receptor-mediated effects of histamine, reducing symptoms such as pruritus, sneezing, rhinorrhea, and urticaria. It also decreases eosinophil chemotaxis and adhesion molecule expression.
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.
5-10 mg orally once daily; max 10 mg/day. For children's formulation, typical adult dose applies to patients >12 years.
1-2 mg orally twice daily; maximum 4 mg/day.
