How does Dexamethasone work?

Dexamethasone affects gene expression and biological processes through binding to cell receptors. It stops the body from making inflammatory mediators and the immune system from responding. This reduces inflammation and relieves the symptoms of inflammatory and immune diseases. Inflammation releases cytokines. These cytokines help the process of inflammation. Dexamethasone inhibits cytokine production. This lowers inflammation and weakens the defense system.
