Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Glucocorticoid receptor agonist; modulates gene expression to inhibit pro-inflammatory cytokines, phospholipase A2, and NF-κB; suppresses immune response and inflammation.
Betamethasone valerate is a corticosteroid that induces phospholipase A2 inhibitory proteins (lipocortins), which control the release of arachidonic acid from membrane phospholipids, thereby inhibiting prostaglandin and leukotriene synthesis. It has anti-inflammatory, antipruritic, and vasoconstrictive effects.
5-60 mg orally once daily or divided every 12-24 hours; dose depends on condition and severity. For acute exacerbations, 200-400 mg intramuscularly once.
Topical: Apply a thin layer to affected skin once or twice daily. Maximum duration: 2 weeks.

Terminal elimination half-life: 2-4 hours (plasma); biological (tissue) half-life: 18-36 hours due to prolonged glucocorticoid receptor-mediated effects. Half-life prolonged in hepatic disease.
Approximately 1.7 hours after topical application; systemic half-life is short due to rapid metabolism.
Renal (fraction excreted unchanged: <1%); primarily hepatic metabolism to inactive glucuronide and sulfate conjugates eliminated renally and fecally. After oral administration, 12-15% of dose recovered in bile/feces as metabolites.
Renal (primarily as metabolites, <5% unchanged); biliary/fecal elimination accounts for <10%.
