Budesonide is a corticosteroid used to treat Crohn's disease, asthma, COPD, hay fever and allergies, and ulcerative colitis.
The short term effects of corticosteroids are decreased vasodilation and permeability of capillaries, as well as decreased leukocyte migration to sites of inflammation. Corticosteroids binding to the glucocorticoid receptor mediates changes in gene expression that lead to multiple downstream effects over hours to days. Glucocorticoids inhibit neutrophil apoptosis and demargination; they inhibit phospholipase A2, which decreases the formation of arachidonic acid derivatives; they inhibit NF-Kappa B and other inflammatory transcription factors; they promote anti-inflammatory genes like interleukin-10. Lower doses of corticosteroids provide an anti-inflammatory effect, while higher doses are immunosuppressive. High doses of glucocorticoids for an extended period bind to the mineralocorticoid receptor, raising sodium levels and decreasing potassium levels.
Budesonide extended release capsules are indicated for the treatment and maintenance of mild to moderate Crohn’s disease. Various inhaled budesonide products are indicated for prophylactic therapy in asthma and to reduce exacerbations of COPD. A budesonide nasal spray is available over the counter for symptoms of hay fever and upper respiratory allergies. Extended-release capsules are indicated to induce remission of mild to moderate ulcerative colitis and a rectal foam is used for mild to moderate distal ulcerative colitis. In addition, a delayed-release capsule formulation of budesonide is indicated to reduce proteinuria in adults with IgA nephropathy at risk of rapid disease progression. In Europe, budesonide is indicated to treat eosinophilic esophagitis (EoE) in adults.
