Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Recombinant interleukin-2 (IL-2) that activates cellular immunity by promoting proliferation and differentiation of T cells, natural killer cells, and lymphokine-activated killer cells; stimulates cytokine release including TNF, IL-1, and IFN-gamma.
Teriflunomide inhibits dihydroorotate dehydrogenase, a key enzyme in de novo pyrimidine synthesis, thereby reducing proliferation of activated T and B lymphocytes.
600,000 IU/kg (0.037 mg/kg) intravenously every 8 hours for 14 doses, repeated after 9 days for a maximum of 28 doses per course.
7 mg orally once daily with or without food.

Terminal elimination half-life is approximately 85 minutes (range 25-195 minutes) after intravenous infusion; clinical context: short half-life necessitates continuous infusion for sustained immunomodulatory effect.
Clinical Note
moderateTeriflunomide + Gatifloxacin
"Teriflunomide may increase the neuroexcitatory activities of Gatifloxacin."
Clinical Note
moderateTeriflunomide + Rosoxacin
"Teriflunomide may increase the neuroexcitatory activities of Rosoxacin."
Clinical Note
moderateTeriflunomide + Trovafloxacin
"Teriflunomide may increase the neuroexcitatory activities of Trovafloxacin."
Clinical Note
moderateTeriflunomide + Nalidixic acid
Terminal half-life approximately 18-19 days (range 10-30 days) due to enterohepatic recirculation. Clinical context: Requires prolonged elimination (up to 2 years to reach undetectable levels) due to slow clearance; accelerated elimination with cholestyramine or activated charcoal may be needed for toxicity.
Renal (primarily via glomerular filtration and tubular reabsorption with subsequent metabolism; <1% excreted unchanged in urine); fecal/biliary elimination is negligible.
Primarily biliary/fecal (approximately 60% unchanged drug and metabolites in feces, 23% in urine). Renal elimination of unchanged drug is minimal (<0.5%). Enterohepatic recycling contributes to long half-life.
