BROMODIPHENHYDRAMINE HYDROCHLORIDE AND CODEINE PHOSPHATE vs KALLIGA
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.
KALLIGA is a recombinant urate oxidase enzyme that catalyzes the oxidation of uric acid to allantoin, a more soluble and easily excreted metabolite, thereby reducing serum uric acid levels.
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.
0.5 mg orally once daily, titrated to 1 mg once daily after 2-4 weeks if tolerated.

Codeine: 2.5-3.5 h (adults), prolonged in hepatic impairment. Diphenhydramine: 4-8 h (adults), extended in elderly.
Terminal elimination half-life: 12-15 hours in adults; prolonged to 24-30 hours in severe renal impairment (CrCl <30 mL/min)
Renal: 70-80% as metabolites (codeine ~10% unchanged; diphenhydramine <5% unchanged). Biliary/fecal: 20-30%.
Renal excretion: 70% unchanged; biliary/fecal: 20% as metabolites; 10% other
