IMPOYZ vs ZURNAI (AUTOINJECTOR)
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
IMPOYZ is a monoclonal antibody that binds to and inhibits the activity of interleukin-23 (IL-23), a cytokine involved in inflammatory and immune responses. By blocking IL-23, it reduces the production of pro-inflammatory cytokines and attenuates the inflammatory cascade.
Hyaluronidase degradation of interstitial hyaluronan, increasing tissue permeability to facilitate fluid dispersion and drug absorption.

Epinephrine 0.3 mg intramuscularly (into anterolateral thigh) every 5-15 minutes as needed for anaphylaxis.

Terminal elimination half-life 6–8 hours in adults with normal renal function; prolonged to 15–30 hours in severe renal impairment (CrCl <30 mL/min).
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.
Primarily renal (70–80% as unchanged drug via glomerular filtration and tubular secretion); biliary/fecal (15–20%) with minor hepatic metabolism.
Primarily renal excretion as unchanged drug or acetylated metabolite (about 70-80% of the dose). A small fraction undergoes biliary/fecal excretion (<10%).
