Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Dexamethasone is a long-acting glucocorticoid receptor agonist, binding to glucocorticoid response elements to modulate gene transcription, resulting in anti-inflammatory, immunosuppressive, anti-allergic, and anti-shock effects.
Glucocorticoid receptor agonist; inhibits phospholipase A2, decreases prostaglandin and leukotriene synthesis; suppresses cytokine production and immune cell activity.
Oral: 0.75–9 mg/day divided every 6–12 hours; IV/IM: 0.5–9 mg/day divided every 6–12 hours.
4-48 mg/day orally in divided doses; 10-40 mg IV/IM bolus, then 10-40 mg IV q4-6h; high-dose IV pulse: 1 g/day for 3 days.

Terminal elimination half-life: 2-3 hours (oral); clinical effects persist longer due to glucocorticoid receptor-mediated genomic actions
