Tác dụng
Description:
Mechanism of Action: Brodalumab is a recombinant human monoclonal (IgG2) antibody which selectively binds to with high affinity and antagonises the interleukin-17 receptor A (IL-17RA). It blocks the activity with cytokine IL-17RA IL-17A, IL-17F, IL-17A/F heterodimer and IL-25, leading to inhibition of cytokine-induced responses, including release of inflammatory cytokines and chemokines. Pharmacokinetics: Absorption: Bioavailability: Approx 55% (SC). Time to peak plasma concentration: Approx 3 days. Distribution: Crosses placenta, enters breastmilk (small amounts). Volume of distribution: 8.9 ± 9.4 L. Metabolism: Undergoes degradation via catabolic pathways into small peptides and amino acids. |
