Does dexamethasone belong to a class of family ?

Dexamethasone comes under corticosteroid class of medicines. It reduces your immune system’s response to many illnesses, which helps to alleviate symptoms including swelling and allergic responses.

What is the mechanism action of dexamethasone?

It works by inhibiting neutrophils migration and lowering lymphocyte colony growth. The capillary membrane also gets less porous. Lysosomal membranes have become more stable. Vitamin A compounds, prostaglandins, and certain cytokines (interleukin-1, interleukin-12, interleukin-18, tumour necrosis factor, interferon-gamma, and granulocyte-macrophage colony-stimulating factor) are increased in the serum.

Is dexamethasone used as an antiemetic?

Dexamethasone is a corticosteroid that possesses antiemetic and anti-inflammatory properties. When taken in conjunction with other medications, dexamethasone has been shown to boost antiemetic or analgesic effectiveness, with minimal adverse effects when administered as a single agent.
