HISTAFED vs KALLIGA
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
HISTAFED is a combination of pseudoephedrine, a sympathomimetic amine that acts as a decongestant by stimulating alpha-adrenergic receptors in the nasal mucosa causing vasoconstriction, and triprolidine, a first-generation antihistamine that competes with histamine for H1-receptor sites on effector cells in the gastrointestinal tract, blood vessels, and respiratory tract, thereby preventing histamine-mediated effects.
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.
60 mg orally every 4 to 6 hours as needed; maximum 360 mg per day.
0.5 mg orally once daily, titrated to 1 mg once daily after 2-4 weeks if tolerated.

3-4 hours for pseudoephedrine component; shorter in children (2-3 h), prolonged in renal impairment
Terminal elimination half-life: 12-15 hours in adults; prolonged to 24-30 hours in severe renal impairment (CrCl <30 mL/min)
Renal (approximately 65% as unchanged drug and metabolites), biliary/fecal (35%)
Renal excretion: 70% unchanged; biliary/fecal: 20% as metabolites; 10% other
