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.
Dexamethasone is a long-acting glucocorticoid receptor agonist that suppresses inflammation and immune responses by inhibiting phospholipase A2, reducing prostaglandin and leukotriene synthesis, and modulating gene expression.
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.

The terminal elimination half-life after topical application is approximately 3.7 hours, consistent with rapid systemic clearance of absorbed drug.
Terminal half-life approximately 3-4 hours (dexamethasone), with clinical effects persisting 36-54 hours due to glucocorticoid receptor-mediated actions.
Primarily renal (minimal biliary/fecal). After topical application, less than 2.5% of the dose is excreted in urine as metabolites.
Renal (primarily as metabolites, ~60%), biliary/fecal (~30%), with <5% excreted unchanged.
