Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Selective histamine H1 receptor antagonist; inhibits histamine-mediated allergic and inflammatory responses.
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.
1 capsule (200 mg) orally every 12 hours.
0.5 mg orally once daily, titrated to 1 mg once daily after 2-4 weeks if tolerated.
