KYXATA vs REDEMPLO
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Selective endothelin receptor antagonist (ERA) targeting endothelin type A (ETA) receptors, reducing pulmonary vascular resistance and remodeling in pulmonary arterial hypertension (PAH).
REDEMPLO is a synthetic tricyclic analog that acts as a selective serotonin-norepinephrine-dopamine reuptake inhibitor (SNDRI). It binds to the presynaptic transporters for serotonin (SERT), norepinephrine (NET), and dopamine (DAT), inhibiting their reuptake and increasing synaptic concentrations of these monoamines. Additionally, it has weak antagonistic properties at the 5-HT2A and alpha-2 adrenergic receptors, contributing to its antidepressant and anxiolytic effects.
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.
100 mg orally once daily, with or without food.

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).
Terminal elimination half-life is 12-15 hours in healthy adults; prolonged in hepatic impairment (up to 30 hours) and end-stage renal disease (up to 40 hours).
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.
Primarily hepatic metabolism with 70% renal excretion of metabolites and 30% fecal elimination; less than 5% excreted unchanged in urine.
