Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Dexamethasone is a long-acting glucocorticoid receptor agonist that suppresses inflammation and immune responses by inhibiting phospholipase A2, reducing prostaglandin and leukotriene synthesis, and modulating gene expression.
Corticosteroid with glucocorticoid and mineralocorticoid activity; binds to glucocorticoid receptors, modulating gene expression to suppress inflammation and immune response.
1.5 mg orally once daily
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.

Terminal half-life approximately 3-4 hours (dexamethasone), with clinical effects persisting 36-54 hours due to glucocorticoid receptor-mediated actions.
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 (primarily as metabolites, ~60%), biliary/fecal (~30%), with <5% excreted unchanged.
Renal: <5% unchanged; hepatic metabolism to inactive metabolites, primarily conjugated and excreted in urine; <2% fecal
