Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Dexamethasone is a glucocorticoid receptor agonist that modulates gene expression to produce anti-inflammatory and immunosuppressive effects by inhibiting phospholipase A2, reducing prostaglandin and leukotriene synthesis, and suppressing cytokine production.
Corticosteroid that binds to glucocorticoid receptors, leading to inhibition of phospholipase A2, decreased prostaglandin and leukotriene synthesis, and suppression of inflammatory cytokines.
Oral: 0.75-9 mg/day in divided doses; IV: 0.5-9 mg/day every 6-12 hours; IM: 4-20 mg every 2 weeks.
Intramuscular: 40-80 mg every 4 weeks. Intra-articular: 5-40 mg depending on joint size. Topical: Apply thin film to affected area 2-4 times daily.

Plasma terminal elimination half-life is 2.8-3.5 hours in adults, but the biological half-life (duration of HPA axis suppression) is 24-36 hours due to prolonged receptor occupancy
Terminal elimination half-life approximately 2-5 hours; but suppression of adrenal function (HPA axis) can persist for 7-30 days depending on dose and duration.
Renal (approximately 80% as inactive metabolites, <5% unchanged), biliary/fecal (minor, approximately 15-20%)
Renal (primarily as metabolites, <5% unchanged); biliary/fecal (minor).
