FILKRI vs TOFACITINIB CITRATE
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; inhibits JAK1, JAK2, JAK3, and tyrosine kinase 2 (TYK2), thereby modulating cytokine signaling and downregulating immune and inflammatory responses.
Filbanserin 100 mg orally once daily at bedtime.
5 mg orally twice daily for rheumatoid arthritis, psoriatic arthritis, and ulcerative colitis; 10 mg orally twice daily for ulcerative colitis induction (8 weeks maximum).

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 elimination half-life is approximately 3 hours (range 2–4 hours) in patients with normal renal function, allowing twice-daily dosing. Half-life is prolonged in moderate to severe renal impairment (up to 5–8 hours) and in hepatic impairment.
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.
Approximately 70% of the dose is eliminated by hepatic metabolism, with about 30% excreted unchanged in urine and <10% in feces. Renal excretion accounts for ~30% of total clearance.
