Mechanism & Pharmacology

Dexamethasone operates primarily as a potent glucocorticoid, interacting with the body's corticosteroid receptors to exert significant anti-inflammatory and immunosuppressive effects. It works by inhibiting the production of substances that trigger inflammatory responses, effectively dampening the immune system's activity. When dexamethasone enters the bloodstream, it binds to protein receptors, influencing gene expression. This interaction alters how cells respond to stress and inflammation, resulting in reduced swelling and pain. Dexamethasone is often used in treatments for various conditions, including asthma, allergies, arthritis, and certain cancers.

Simplified explanation (patient-friendly)

Dexamethasone helps reduce inflammation and control your body's immune response. Imagine it like a calming agent that tells your immune system to take a step back when it’s overreacting. This is especially useful in cases of allergies or inflammation, where your body needs to cool down and heal. By slowing down immune reactions, dexamethasone makes it easier for the body to recover from various conditions.

Clinical terms

According to the Health Canada-approved monograph, dexamethasone exhibits glucocorticoid activity, leading to the suppression of leukocyte infiltration at the site of inflammation.
