Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Dexamethasone is a glucocorticoid receptor agonist, binding to the glucocorticoid receptor (GR) and modulating gene expression through transactivation and transrepression. It inhibits phospholipase A2, reduces prostaglandin and leukotriene synthesis, suppresses cytokine production (IL-1, IL-2, IL-6, TNF-alpha), and decreases immune cell migration and activation.
Budesonide is a corticosteroid with potent glucocorticoid activity and weak mineralocorticoid activity. It binds to the glucocorticoid receptor, leading to anti-inflammatory effects via inhibition of inflammatory mediators such as cytokines and prostaglandins.
0.5 mg orally once daily, with gradual taper to lowest effective dose
9 mg orally once daily in the morning for up to 8 weeks.

3.0-4.5 hours; prolonged in hepatic impairment (up to 6-8 hours) or concurrent CYP3A4 inhibitors
Terminal elimination half-life is approximately 2-3 hours; clinically, the extended intestinal release formulation maintains local activity despite short systemic half-life.
Renal: 70-80% (mostly as 6β-hydroxydexamethasone); biliary/fecal: 10-15%
Primarily fecal (60-70%) with minimal renal excretion (<10%); extensively metabolized hepatically, metabolites excreted in bile and feces.
