BROMODIPHENHYDRAMINE HYDROCHLORIDE AND CODEINE PHOSPHATE vs TELDRIN
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Bromodiphenhydramine hydrochloride is a first-generation antihistamine that antagonizes histamine H1 receptors, reducing allergic symptoms. Codeine phosphate is an opioid agonist at mu-opioid receptors, producing analgesia and antitussive effects. Combination provides enhanced cough suppression.
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 mL of oral solution (containing bromodiphenhydramine hydrochloride 12.5 mg and codeine phosphate 10 mg) every 4-6 hours as needed; maximum 4 doses in 24 hours.
1-2 mg orally twice daily; maximum 4 mg/day.

Codeine: 2.5-3.5 h (adults), prolonged in hepatic impairment. Diphenhydramine: 4-8 h (adults), extended in elderly.
Terminal half-life: 9-12 hours (range 8-14) in healthy adults; prolonged in renal impairment.
Renal: 70-80% as metabolites (codeine ~10% unchanged; diphenhydramine <5% unchanged). Biliary/fecal: 20-30%.
Renal: 55-60% unchanged; fecal: 35-40%; minor biliary elimination.
