Description

General description

Dexamethasone is a potent glucocorticoid with minimal to no mineralocorticoid activity. Dexamethasone exhibits pleiotropic effects on multiple signaling pathways, some of its functions include, inhibition of neutrophil migration and reduction of lymphocyte colony proliferation. Research findings show, dexamethasone might prevent high-altitude pulmonary edema by decreasing pulmonary artery pressure.

Application

Dexamethasone has been used:

• in culture media to induce differentiation of adipose-derived stem cells into osteogenic tissue
• as a component of adipocyte differentiation medium
• for in vitro stimulation of primary normal human bronchial epithelial cells (NHBE) and airway smooth muscle (ASM)

Biochem/physiol Actions

Dexamethasone is known to be effective against relapsed multiple myeloma. It is found to decrease inflammation associated with cerebrospinal fluid and central nervous system (CNS) complications, such as hearing loss.

Glucocorticoid anti-inflammatory agent. Regulates T cell survival, growth, and differentiation. Inhibits the induction of nitric oxide synthase.
