KALEXATE vs PROZAC WEEKLY
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
KALEXATE is a monoclonal antibody that binds to both soluble and membrane-bound human interleukin-6 (IL-6) receptors, inhibiting IL-6-mediated signaling. IL-6 is a pro-inflammatory cytokine implicated in the pathogenesis of rheumatoid arthritis and other inflammatory conditions.
Selective serotonin reuptake inhibitor (SSRI); potentiates serotonergic activity by blocking reuptake of serotonin at the presynaptic neuronal membrane.

12-15 hours; prolonged in renal impairment (up to 30 hours in severe cases)
Fluoxetine: 4-6 days after single dose, 4-6 days (extended to 7-9 days with chronic dosing due to autoinhibition of CYP2D6); norfluoxetine: 9-31 days. Steady state achieved after 2-4 weeks.
Primarily renal (75-80% as unchanged drug); biliary/fecal (15-20%)
Renal excretion of metabolites (primarily fluoxetine glucuronide and norfluoxetine glucuronide) accounts for approximately 80% of elimination; fecal excretion accounts for approximately 15%.
