Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Topical corticosteroid that induces phospholipase A2 inhibitory proteins, collectively called lipocortins, which inhibit the release of arachidonic acid, thereby reducing prostaglandin and leukotriene synthesis, and exerting anti-inflammatory, antipruritic, and vasoconstrictive effects.
Corticosteroid that binds to glucocorticoid receptors, modulating gene expression to suppress inflammation and immune responses, and inhibit phospholipase A2, reducing prostaglandin and leukotriene synthesis.
Topical: Apply a thin film to affected area 3-4 times daily. Dosage strength: 0.5% cream or ointment.
Hydrocortisone (Cort-Dome) typical adult dose: 100 mg intravenously or intramuscularly as a loading dose, followed by 50-100 mg intravenously every 6 hours for stress dosing; for replacement therapy: oral 20-30 mg daily in divided doses. Topical: apply sparingly to affected area 1-4 times daily.

Terminal elimination half-life: 1–2 hours for hydrocortisone (active component), prolonged in liver disease or with concurrent CYP3A4 inhibitors.
Plasma half-life is approximately 1-2 hours; biological half-life (duration of adrenal suppression) is 18-36 hours.
Primarily hepatic metabolism (approximately 95%) followed by renal excretion of inactive metabolites (<5% unchanged). Biliary/fecal excretion is negligible.
Primarily hepatic metabolism; renal excretion of inactive metabolites accounts for approximately 40-60% of elimination; less than 5% excreted unchanged in urine; biliary/fecal elimination is minor (<5%).
