FILKRI vs TOFACITINIB
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
FILKRI is a sodium–glucose cotransporter 2 (SGLT2) inhibitor. It inhibits SGLT2 in the proximal renal tubule, reducing glucose reabsorption and increasing urinary glucose excretion, thereby lowering blood glucose levels.
Janus kinase (JAK) inhibitor, primarily inhibiting JAK1 and JAK3, thereby modulating the JAK-STAT signaling pathway to reduce cytokine production and immune cell activation.
Filbanserin 100 mg orally once daily at bedtime.
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 12-16 hours in healthy adults; may be prolonged in hepatic impairment (up to 24 hours) and dose adjustment recommended.
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.
Renal excretion of unchanged drug accounts for approximately 60-70% of elimination; biliary/fecal excretion accounts for 20-30%; minor metabolism (10-15%) via CYP3A4.
Primarily renal (70%) with 30% excreted unchanged in urine. Fecal elimination accounts for 20% (<1% unchanged). Minor biliary excretion.
