IMPOYZ vs KYXATA
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.
Selective endothelin receptor antagonist (ERA) targeting endothelin type A (ETA) receptors, reducing pulmonary vascular resistance and remodeling in pulmonary arterial hypertension (PAH).
100 mg orally twice daily
KYXATA (landiolol) intravenously: For atrial fibrillation/flutter (AF/AFL) with rapid ventricular rate: Initial intravenous bolus dose of 0.125 mg/kg over 1 minute, followed by continuous intravenous infusion of 0.05 to 0.2 mg/kg/min, titrated to heart rate control. Maximum infusion rate is 0.4 mg/kg/min.

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 12–15 hours in adults with normal renal function; extends to 22–30 hours in moderate renal impairment (CrCl 30–50 mL/min) and up to 48 hours in severe impairment (CrCl <30 mL/min).
Primarily renal (70–80% as unchanged drug via glomerular filtration and tubular secretion); biliary/fecal (15–20%) with minor hepatic metabolism.
Renal excretion accounts for approximately 70% of elimination (60% unchanged, 10% as metabolites); biliary/fecal excretion accounts for 25% (primarily as metabolites); minor metabolic clearance (5%) via CYP3A4.
