Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Clobetasol propionate is a corticosteroid with high potency that binds to glucocorticoid receptors, thereby modulating gene expression to inhibit inflammatory mediators (e.g., prostaglandins, leukotrienes) and suppress immune responses. It also induces vasoconstriction and reduces edema.
Prednisolone is a synthetic glucocorticoid that binds to the glucocorticoid receptor, modulating gene transcription to suppress inflammation, immune response, and adrenal function.
0.05% spray applied to affected area twice daily. Apply twice daily to affected areas of the scalp or body. Do not use more than 2 consecutive weeks or exceed 50 g/week.
20-40 mg intramuscularly every 3 weeks; for intra-articular use: 20-40 mg per large joint, 10-20 mg per medium joint, 4-10 mg per small joint.

The terminal elimination half-life after topical application is approximately 3.7 hours, consistent with rapid systemic clearance of absorbed drug.
Plasma t1/2 ~2.5-3.5 hours. Duration of adrenal suppression may persist for 24-48 hours.
Primarily renal (minimal biliary/fecal). After topical application, less than 2.5% of the dose is excreted in urine as metabolites.
Primarily renal (80-90% as inactive metabolites and unchanged drug). Biliary excretion accounts for <5%.
