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.
Betamethasone is a corticosteroid that binds to the glucocorticoid receptor, leading to anti-inflammatory and immunosuppressive effects by inhibiting phospholipase A2, reducing prostaglandin and leukotriene synthesis, and modulating gene expression.
Topical: Apply a thin film to affected area 3-4 times daily. Dosage strength: 0.5% cream or ointment.
0.1 mg topical cream applied to affected area twice daily

Terminal elimination half-life: 1–2 hours for hydrocortisone (active component), prolonged in liver disease or with concurrent CYP3A4 inhibitors.
Terminal elimination half-life is approximately 12-15 hours in adults with normal renal function. In patients with creatinine clearance <30 mL/min, half-life may extend to 30-40 hours, requiring dose adjustment.
Primarily hepatic metabolism (approximately 95%) followed by renal excretion of inactive metabolites (<5% unchanged). Biliary/fecal excretion is negligible.
Renal excretion of unchanged drug accounts for 60-80% of the dose. Hepatic metabolism produces inactive metabolites, with approximately 15-25% eliminated via bile and feces. A small fraction (5-10%) is excreted unchanged in feces.
