Mechanism of Action
How dexamethasone works in the body
Dexamethasone, a synthetic glucocorticoid steroid, exerts its therapeutic effects by binding to specific glucocorticoid receptors in the cytoplasm of target cells. Once bound, the dexamethasone-glucocorticoid receptor complex enters the cell nucleus and interacts with DNA, leading to the regulation of gene expression. This mechanism allows dexamethasone to modulate various physiological processes and suppress inflammation and immune responses.
Effects on the immune system
Dexamethasone has potent immunosuppressive properties, which make it effective in treating inflammatory conditions and autoimmune disorders. By inhibiting the production of inflammatory mediators, such as cytokines and prostaglandins, dexamethasone can reduce inflammation and alleviate symptoms associated with conditions like rheumatoid arthritis and asthma. It also blocks the activity of immune cells, such as T cells and B cells, thereby suppressing immune responses.
Dexamethasone’s immunosuppressive effects have been particularly relevant during the COVID-19 pandemic. Studies have shown that dexamethasone can improve outcomes for critically ill COVID-19 patients by reducing the severity of inflammation and preventing cytokine storms, a potentially life-threatening immune response.
Metabolism and Elimination

Dexamethasone is well-absorbed when taken orally and rapidly distributes to various tissues throughout the body. It can also be administered via intravenous, intramuscular, and topical routes, with absorption rates varying depending on the route of administration. The drug crosses the blood-brain barrier and has high penetration into cells.
Metabolic pathways and breakdown of dexamethasone
Dexamethasone undergoes extensive hepatic metabolism through enzymatic processes mediated primarily by cytochrome P450 enzymes, particularly CYP3A4. These metabolic pathways convert dexamethasone into inactive metabolites, which are then eliminated from the body.
Excretion through urine and feces
The elimination of dexamethasone and its metabolites primarily occurs through the kidneys, both by glomerular filtration and tubular secretion. A small portion of the drug and its metabolites may also be excreted in the feces. The elimination half-life of dexamethasone varies among individuals, and factors such as renal function and age can influence the rate of excretion.
