Mechanism of action

Systemic corticosteroids reduce inflammation by inhibiting pro-inflammatory cytokine production and immune cell activation. Methotrexate acts as a disease-modifying antirheumatic drug (DMARD) by inhibiting dihydrofolate reductase, reducing cell proliferation and immune responses. Together, they provide complementary immunosuppressive effects for treating autoimmune and inflammatory conditions.
