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.
Corticosteroid with glucocorticoid and mineralocorticoid activity; binds to glucocorticoid receptors, modulating gene expression to suppress inflammation and immune response.
0.5 mg orally once daily, with gradual taper to lowest effective dose
Prednisolone: 5-60 mg orally once daily or divided twice daily; methylprednisolone: 4-48 mg orally once daily or divided twice daily. Dose and duration vary by indication.

3.0-4.5 hours; prolonged in hepatic impairment (up to 6-8 hours) or concurrent CYP3A4 inhibitors
Terminal elimination half-life: 3.0-3.5 hours; clinical context: requires multiple daily doses for sustained effect; biological half-life (duration of HPA suppression) longer (~24-36 hours) due to intracellular activity
Renal: 70-80% (mostly as 6β-hydroxydexamethasone); biliary/fecal: 10-15%
Renal: <5% unchanged; hepatic metabolism to inactive metabolites, primarily conjugated and excreted in urine; <2% fecal
