DIPHENHYDRAMINE HYDROCHLORIDE PRESERVATIVE FREE vs KALLIGA
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Competitive antagonist of histamine H1 receptors; centrally acting anticholinergic agent that inhibits acetylcholine muscarinic receptors.
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.
25 to 50 mg intravenously or intramuscularly every 4 to 6 hours as needed; maximum 400 mg per day.
0.5 mg orally once daily, titrated to 1 mg once daily after 2-4 weeks if tolerated.

Terminal elimination half-life: 4-10 hours (mean ~8 hours); prolonged in hepatic impairment or elderly (up to 20 hours).
Terminal elimination half-life: 12-15 hours in adults; prolonged to 24-30 hours in severe renal impairment (CrCl <30 mL/min)
Primarily renal as inactive metabolites; ~60% of a dose appears in urine as metabolites, with <5% unchanged. Minor biliary/fecal elimination (<10%).
Renal excretion: 70% unchanged; biliary/fecal: 20% as metabolites; 10% other
