BARICITINIB vs Ruxolitinib
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Baricitinib is a Janus kinase (JAK) inhibitor, selectively inhibiting JAK1 and JAK2, thereby modulating the signaling pathway involved in inflammatory responses.
Selective inhibitor of Janus-associated kinases (JAK) JAK1 and JAK2, reducing cytokine signaling and hematopoiesis.
2 mg orally once daily; may increase to 4 mg once daily if inadequate response.
Myelofibrosis: 5-25 mg orally twice daily based on platelet count; Polycythemia Vera: 10 mg orally twice daily; Graft-versus-Host Disease: 5-10 mg orally twice daily.

Terminal elimination half-life is approximately 12.5 hours in healthy subjects; allowing once-daily dosing with steady-state reached in 2-3 days.
Clinical Note
moderateRuxolitinib + Digoxin
"Ruxolitinib may increase the bradycardic activities of Digoxin."
Clinical Note
moderateRuxolitinib + Digitoxin
"Ruxolitinib may decrease the cardiotoxic activities of Digitoxin."
Clinical Note
moderateRuxolitinib + Deslanoside
"Ruxolitinib may decrease the cardiotoxic activities of Deslanoside."
Clinical Note
moderateRuxolitinib + Acetyldigitoxin
"Ruxolitinib may decrease the cardiotoxic activities of Acetyldigitoxin."
The terminal elimination half-life of ruxolitinib is approximately 3 hours for the parent drug. However, the pharmacodynamic half-life for JAK2 inhibition is longer (up to 8-12 hours) due to sustained target suppression.
Approximately 75% of the dose is excreted in urine (69% as unchanged drug, 6% as metabolites), and 20% in feces (15% unchanged, 5% metabolites).
Ruxolitinib is primarily metabolized in the liver, and its metabolites are excreted renally. Approximately 74% of the dose is eliminated in urine (mainly as metabolites) and 22% in feces (as unchanged drug and metabolites).
