What is Corticosteroid Dexamethasone?

This drug is available in various forms, including oral tablets, injectable solutions, and topical preparations, making it versatile in its applications. (Source)

How Does It Work?

Dexamethasone works by binding to glucocorticoid receptors in the body, which influences the expression of certain genes involved in the inflammatory response. This action leads to a reduction in the production of pro-inflammatory cytokines and other mediators, effectively decreasing inflammation and immune activity. (Source)

Mechanism of Action
