ZURNAI (AUTOINJECTOR) vs ZUSDURI
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Hyaluronidase degradation of interstitial hyaluronan, increasing tissue permeability to facilitate fluid dispersion and drug absorption.
ZUSDURI is a small molecule inhibitor of Janus kinase 1 (JAK1) and Janus kinase 2 (JAK2), reducing signaling of pro-inflammatory cytokines.
Epinephrine 0.3 mg intramuscularly (into anterolateral thigh) every 5-15 minutes as needed for anaphylaxis.
200 mg orally once daily, with or without food.

Terminal elimination half-life is approximately 2.5 hours in adults. In renal impairment, half-life may extend up to 6 hours, necessitating dosing adjustments.
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.
Primarily renal excretion as unchanged drug or acetylated metabolite (about 70-80% of the dose). A small fraction undergoes biliary/fecal excretion (<10%).
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.
