Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Calcineurin inhibitor that binds to FKBP-12, forming a complex that inhibits calcineurin, thereby preventing dephosphorylation and nuclear translocation of NFAT, which reduces T-cell activation and cytokine production (e.g., IL-2).
Cyclosporine is a calcineurin inhibitor. It binds to cyclophilin, forming a complex that inhibits calcineurin, thereby blocking the dephosphorylation and nuclear translocation of NF-AT, reducing T-cell activation and cytokine production.
Initial oral dose of 0.1-0.15 mg/kg/day divided every 12 hours, with subsequent adjustments based on trough levels. Typical maintenance dose 0.05-0.15 mg/kg/day.
Initial oral dose: 10-15 mg/kg/day divided q12h, then taper to 5-10 mg/kg/day. IV dose: 5-6 mg/kg/day continuous infusion or divided q12h.

Terminal elimination half-life is approximately 43 hours (range 15.8–68.6 hours) in adult kidney transplant recipients. This long half-life supports once-daily dosing. In liver transplant patients, half-life ranges from 12 to 42 hours.
Terminal elimination half-life is approximately 8.4 hours (range 6–24 hours) in adults; prolonged in patients with hepatic impairment.
Primarily fecal (94.6%) via biliary elimination. Renal excretion accounts for approximately 2.4% of the dose, mainly as metabolites. Less than 1% is excreted unchanged in urine.
Primarily biliary/fecal (94% of metabolites); renal elimination is minimal (<6% as unchanged drug and metabolites).
