CIBINQO vs TOFACITINIB
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
CIBINQO (abrocitinib) is a Janus kinase (JAK) inhibitor. It selectively inhibits JAK1, which modulates cytokine signaling involved in inflammatory pathways, including interleukin (IL)-4, IL-13, IL-31, and interferon-gamma, reducing the inflammatory response in atopic dermatitis.
Janus kinase (JAK) inhibitor, primarily inhibiting JAK1 and JAK3, thereby modulating the JAK-STAT signaling pathway to reduce cytokine production and immune cell activation.
100 mg orally once daily, with or without food.
5 mg orally twice daily; extended-release formulation 11 mg orally once daily. For rheumatoid arthritis, psoriatic arthritis, ulcerative colitis, and polyarticular course juvenile idiopathic arthritis. For ulcerative colitis, induction: 10 mg orally twice daily for 8 weeks, then maintenance 5 mg twice daily.

Clinical Note
moderateTofacitinib + Digoxin
"Tofacitinib may increase the bradycardic activities of Digoxin."
Clinical Note
moderateTofacitinib + Bendroflumethiazide
"Tofacitinib may increase the bradycardic activities of Bendroflumethiazide."
Clinical Note
moderateTofacitinib + Sulfisoxazole
"The metabolism of Sulfisoxazole can be decreased when combined with Tofacitinib."
Clinical Note
moderateTofacitinib + Erythromycin
Terminal elimination half-life is approximately 4-6 hours in healthy subjects, supporting twice-daily dosing. No significant accumulation after multiple doses.
Terminal half-life approximately 3.3 hours in healthy volunteers. In patients with rheumatoid arthritis, effective half-life ~3-6 hours due to reversible binding to JAK enzymes. No significant accumulation at steady state.
Primarily excreted via feces (69%) and urine (20%) after oral administration. Renal elimination accounts for <1% of unchanged drug. Biliary excretion is the major route for metabolites.
Primarily renal (70%) with 30% excreted unchanged in urine. Fecal elimination accounts for 20% (<1% unchanged). Minor biliary excretion.
