Mechanism of action

Tocilizumab is a monoclonal antibody that binds to IL-6 receptors (both membrane-bound and soluble forms), blocking the pro-inflammatory cytokine IL-6 from activating immune cells. Methotrexate is a disease-modifying antirheumatic drug (DMARD) that inhibits dihydrofolate reductase, reducing nucleotide synthesis and thereby suppressing T-cell and B-cell proliferation. Together, this combination targets inflammation through complementary mechanisms.
