What is Dexamethasone Injectable?

Dexamethasone injectable is a corticosteroid medication that belongs to the class of drugs known as glucocorticoids. It is used to reduce inflammation and suppress the immune system in various medical conditions.

Dexamethasone works by binding to specific receptors in the cells and modulating gene expression. This leads to a wide range of effects, including decreased inflammation, reduced immune response, and altered metabolism of carbohydrates, proteins, and fats.
