Mechanism of action

These synthetic glucocorticoids mimic the action of cortisol and exert broad anti-inflammatory and immunosuppressive effects by inhibiting the production of pro-inflammatory cytokines, reducing immune cell proliferation and migration, and stabilizing lysosomal membranes. They are used across multiple therapeutic areas due to their potent ability to dampen both innate and adaptive immune responses.
