Glensoludex is a glucocorticoid, a steroid hormone, used to treat a variety of medical conditions, including allergies, inflammatory and autoimmune diseases, and some types of cancer. Glensoludex is a potent immunosuppressant drug, and may be used to reduce inflammation and swelling as well as to suppress the body's own immune response.

Uses for

Glensoludex is commonly prescribed for long-term treatment of conditions such as allergies, asthma, arthritis, ulcerative colitis, lupus, multiple sclerosis, and certain types of cancer.

Mechanism of Action

The primary mechanism of action of dexamethasone is to reduce inflammation by inhibiting the production of inflammatory mediators such as cytokines from immune cells. It also reduces the expression of cell receptors for inflammatory mediators, thus preventing the binding of inflammatory mediators to the cell. This reduces the inflammatory response.

How long does it take to work?

The effects of dexamethasone may begin within 2-3 days after starting treatment, however, it may take up to a few weeks for the full effects to become apparent.


Glensoludex is rapidly and almost completely absorbed from the gastrointestinal tract into the bloodstream.

Route of Elimination

Glensoludex is eliminated from the body through the kidneys, primarily in the form of metabolites.


The usual adult dose for oral administration is 4 to 48 mg/day in divided doses, taken with food. A lower dose can be prescribed for those who have impaired renal function. The dosage may also vary depending on the patient's age, weight, diagnosis, and response to treatment. The pediatric dose ranges from 0.08 mg/kg to 0.3 mg/kg, again divided into several doses administered with food.
