1.What is Dexamethasone?
Dexamethasone is a fluorinated steroid that is 9-fluoropregna-1,4-diene substituted by hydroxy groups at positions 11, 17 and 21, a methyl group at position 16 and oxo groups at positions 3 and 20. It is a synthetic member of the class of glucocorticoids. It has a role as an adrenergic agent, an antiemetic, an antineoplastic agent, an environmental contaminant, a xenobiotic, an immunosuppressive agent and an anti-inflammatory drug. It is a fluorinated steroid, a 3-oxo-Delta(1),Delta(4)-steroid, a glucocorticoid, a 20-oxo steroid, an 11beta-hydroxy steroid, a 17alpha-hydroxy steroid and a 21-hydroxy steroid. It derives from a hydride of a pregnane.
2.What is it used for?
Dexamethasone is used for the same indications as all corticosteroids; however, it exhibits a significantly more powerful anti-inflammatory and anti-allergic action. It is used for circulatory collapse—shock during or after surgical operations, trauma, blood loss, myocardial infarction, and burns. It is also used in severe infections—toxemia, vascular collapse in meningococcosis, septicemia, diphtheria, typhoid fever, and peritonitis. It is used in severe allergic conditions—asthmatic status, laryngeal edema, severe anaphylactic reactions to medicinal drugs, and pyrogenic reactions.
Anti-inflammatory glucocorticoidDexamethasone is used to treat inflammatory and autoimmune conditions such as rheumatoid arthritis and bronchospasm. It is useful to study apoptosis, cell signaling pathways and gene expression. It is associated with marbofloxacin and clotrimazole and finds application in veterinary medicine to treat difficult ear infections in dogs. It is also used to treat horses with swelling of of distal limbs and general bruising in combination with trichlormethiazide. It is also an anti-inflammatory glucocorticoid.
