AMBODRYL vs TELDRIN
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Antihistamine (H1-receptor antagonist) with anticholinergic and sedative properties.
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.
10-20 mg intramuscularly or intravenously every 4-6 hours as needed, up to a maximum of 80 mg/day.
1-2 mg orally twice daily; maximum 4 mg/day.

Terminal elimination half-life 12-15 hours in adults; prolonged to 20-30 hours in hepatic impairment.
Terminal half-life: 9-12 hours (range 8-14) in healthy adults; prolonged in renal impairment.
Primarily renal (70-80% as metabolites, 20-30% unchanged); biliary/fecal excretion accounts for 15-20%.
Renal: 55-60% unchanged; fecal: 35-40%; minor biliary elimination.
