NCIt definition : A synthetic glucocorticosteroid for topical use, with anti-inflammatory activity.
Desonide binds to glucocorticoid receptors in the cytoplasm, and the ligand-receptor
complex is translocated as a homodimer into the nucleus, where transcription activation
via glucocorticoid response elements within glucocorticoid-responsive genes occur.
This agent induces transcription of genes coding for anti-inflammatory proteins, including
lipocortin-1, interleukin-10, interleukin-1 receptor antagonist and neutral endopeptidase.
Increased synthesis of lipocortin-1 has an inhibitory effect on phospholipase A2,
which in turn inhibits the release arachidonic acid, thereby controlling the biosynthesis
of potent mediators of inflammation such as prostaglandins and leukotrienes.;
