WEZLANA vs ZUSDURI
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
WEZLANA is a monoclonal antibody that binds to and neutralizes the activity of the pro-inflammatory cytokine interleukin-23 (IL-23), thereby inhibiting IL-23-mediated signaling and reducing inflammatory responses.
ZUSDURI is a small molecule inhibitor of Janus kinase 1 (JAK1) and Janus kinase 2 (JAK2), reducing signaling of pro-inflammatory cytokines.
IV: 500 mg every 12 hours over 60 minutes.
200 mg orally once daily, with or without food.

12 hours (range 10-14 hours); clinically, steady-state is achieved after 2-3 days of dosing.
The terminal elimination half-life is approximately 12–15 hours in healthy adults, supporting twice-daily dosing. In patients with hepatic impairment, half-life may be prolonged up to 24 hours, requiring dose adjustment.
Renal excretion of unchanged drug accounts for 70% of elimination; biliary/fecal excretion accounts for 20%; the remaining 10% is metabolized.
ZUSDURI is primarily eliminated via hepatic metabolism with subsequent biliary excretion. Approximately 30% of the dose is excreted unchanged in feces, and less than 5% is recovered unchanged in urine. The major metabolites are excreted in bile and eliminated in feces.
