TAVIST vs TELDRIN
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Antihistamine; selective inverse agonist at histamine H1 receptors, blocking histamine-mediated allergic and inflammatory responses.
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.
1.34 mg orally twice daily; maximum 8.04 mg/day.
1-2 mg orally twice daily; maximum 4 mg/day.

Terminal elimination half-life is 12-15 hours in healthy adults; prolonged in renal/hepatic impairment.
Terminal half-life: 9-12 hours (range 8-14) in healthy adults; prolonged in renal impairment.
Renal excretion of metabolites (approx. 60%) and unchanged drug (<5%); biliary/fecal elimination accounts for about 40%.
Renal: 55-60% unchanged; fecal: 35-40%; minor biliary elimination.
