Budesonide-d8 is intended for use as an internal standard for the quantification of budesonide (Item No. 15407) by GC- or LC-MS. Budesonide is a glucocorticoid and an agonist of glucocorticoid receptors (EC50 = 45.7 pM in a transactivation assay).{41565} It is selective for glucocorticoid over mineralocorticoid receptors (EC50 = 7,620 pM). Budesonide inhibits LPS-induced TNF-a release from human peripheral blood mononuclear cells (PBMCs; IC50 = 0.96 nM).{25238} It reduces levels of IL-1B and eotaxin in the lungs and the number of eosinophils and neutrophils in bronchoalveolar lavage fluid (BALF) in a rat model of ovalbumin-induced airway inflammation when administered at a dose of 3 mg/kg.{24240} Intracolonic administration of budesonide decreases colon wet weight and colonic myeloperoxidase (MPO) activity in a rat model of oxazolone-induced colitis.{52378} Formulations containing budesonide have been used in the treatment of Crohn's disease, ulcerative colitis, allergic rhinitis, and asthma.
