Used in pharmaceutical research for its anti-inflammatory properties, particularly in respiratory conditions like asthma and COPD. It is a metabolite of budesonide and contributes to the overall therapeutic effect by modulating glucocorticoid activity in the lungs. Due to its high receptor binding affinity and rapid systemic clearance, it helps reduce inflammation with minimal side effects. Investigated for potential use in targeted inhaled therapies to enhance efficacy and reduce systemic exposure.
