Glucocorticoids decrease the number of eosinophils in the circulation by causing them to exit the bloodstream and move into the tissue. The number of eosinophils released by the bone marrow is suppressed by glucocorticoids. It has also been theorized that glucocorticoids eliminate eosinophils in the blood by causing them to undergo apoptosis. [1]
Glucocorticoids are corticosteroids that bind to the glucocorticoid receptor [1] that is present in almost every vertebrate animal cell. The name "glucocorticoid" is a portmanteau ( gluco se + cort ex + ster oid ) and is composed from its role in regulation of glucose metabolism , synthesis in the adrenal cortex , and its steroidal structure ...
Glucocorticoids exert anti- inflammatory effects to relieve the symptoms by inhibiting the synthesis of prostaglandin and leukotriene, and the release of collagenase and lysosomal enzymes.

Synthetic pharmaceutical drugs with corticosteroid-like effects are used in a variety of conditions, ranging from hematological neoplasms [3] to brain tumors or skin diseases. Dexamethasone and its derivatives are almost pure glucocorticoids, while prednisone and its derivatives have some mineralocorticoid action in addition to the ...
Glucocorticoids also stimulate the lipocortin-1 escaping to the extracellular space, where it binds to the leukocyte membrane receptors and inhibits various inflammatory events: epithelial adhesion, emigration, chemotaxis, phagocytosis, respiratory burst, and the release of various inflammatory mediators (lysosomal enzymes, cytokines, tissue ...
Selective glucocorticoid receptor modulators (SEGRMs) and selective glucocorticoid receptor agonists (SEGRAs) formerly known as dissociated glucocorticoid receptor agonists (DIGRAs) are a class of experimental drugs designed to share many of the desirable anti-inflammatory, immunosuppressive, or anticancer properties of classical glucocorticoid drugs but with fewer side effects such as skin ...
Most esters of these corticosteroids are not included in this list; for esters, see here instead. The most common structural modifications in synthetic corticosteroids include 1(2)-dehydrogenation, 6α-, 9α-, 16α-, and 16β-substitution (with a halogen or methyl group), 16α,17α-acetonidation, and 17α- and 21-esterification.
Antiglucocorticoid drugs are a class of medications that act to reduce the effects of glucocorticoids, primarily cortisol, in the body. [1] They include direct glucocorticoid receptor antagonists such as mifepristone and synthesis inhibitors such as metyrapone, ketoconazole, and aminoglutethimide. They are used to treat Cushing's syndrome. [2]
