Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Antihistamine; binds to histamine H1 receptors, blocking the effects of histamine; also exhibits anticholinergic and mild sedative properties.
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.
