Budesonide
From SNPedia
Budesonide, the generic name for a drug most commonly sold as Rhinocort, is a corticosteroid drug typically used to help control the symptoms of asthma, allergies, rhinitis, and inflammatory bowel disease.
A SNP in the TBX21 gene is reported to influence how well patients with asthma respond to long-term treatment with budesonide; see rs2240017.
