IMPOYZ vs WERA
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.
WERA is a serotonin-norepinephrine reuptake inhibitor (SNRI) that inhibits the reuptake of serotonin and norepinephrine, enhancing neurotransmission in the central nervous system.

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).
The terminal elimination half-life of WERA is approximately 4-6 hours in patients with normal renal function. This relatively short half-life supports twice-daily dosing, but requires dose adjustment in renal impairment.
Primarily renal (70–80% as unchanged drug via glomerular filtration and tubular secretion); biliary/fecal (15–20%) with minor hepatic metabolism.
WERA is predominantly eliminated via the renal route, with approximately 60-70% of the dose excreted unchanged in the urine. Biliary/fecal excretion accounts for 20-30% of elimination, primarily as metabolites. Less than 10% is eliminated via other routes.
