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.
Clobetasol propionate is a potent corticosteroid that binds to glucocorticoid receptors, leading to inhibition of phospholipase A2 activity, decreased arachidonic acid release, and reduced synthesis of inflammatory mediators such as prostaglandins and leukotrienes, thereby exerting anti-inflammatory, antipruritic, and vasoconstrictive effects.
Topical: Apply a thin film to affected area 3-4 times daily. Dosage strength: 0.5% cream or ointment.
Apply topically to affected areas once or twice daily. Maximum 50 g/week for adults. Duration limited to 2 weeks continuous use.

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 5.6 hours (range 3.0–10.5 h) following topical application. Systemic absorption is minimal, but this half-life reflects clearance of absorbed drug.
Primarily hepatic metabolism (approximately 95%) followed by renal excretion of inactive metabolites (<5% unchanged). Biliary/fecal excretion is negligible.
Renal (primarily as metabolites) and fecal. After topical application, <5% of the dose is excreted unchanged in urine; the majority is metabolized hepatically and excreted via bile into feces.
