KALLIGA vs PERIACTIN
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
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.
Cyproheptadine is a first-generation antihistamine with anticholinergic and antiserotonergic properties. It acts as a competitive antagonist at histamine H1 receptors and serotonin 5-HT2 receptors, thereby inhibiting histamine-mediated allergic symptoms and serotonin-mediated effects such as increased gastrointestinal motility and vascular permeability.
0.5 mg orally once daily, titrated to 1 mg once daily after 2-4 weeks if tolerated.
4 mg orally three times daily; adjust as needed. Maximum: 32 mg/day.
