Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Betamethasone dipropionate is a corticosteroid that exerts anti-inflammatory, antipruritic, and vasoconstrictive effects through induction of phospholipase A2 inhibitory proteins (lipocortins) and inhibition of arachidonic acid release, thereby reducing prostaglandin and leukotriene synthesis.
Corticosteroid with anti-inflammatory and immunosuppressant activity; binds to glucocorticoid receptors, modulating gene expression and inhibiting phospholipase A2, thereby reducing prostaglandin and leukotriene synthesis.
Topical: Apply a thin film to affected skin twice daily; maximum 100 g per week for adults.
Adult: 5-60 mg orally every 6-12 hours (hydrocortisone base equivalent), or 10-240 mg IV/IM every 12 hours (as hydrocortisone sodium succinate). Dose depends on severity and condition.

Terminal elimination half-life is approximately 18-36 hours (mean ~24 hours) following topical application; systemic half-life after oral administration is similar, reflecting prolonged tissue retention.
Plasma terminal half-life is approximately 1.5-2 hours. However, biologic half-life (duration of adrenal suppression) is 18-36 hours due to intracellular receptor binding.
Renal excretion of metabolites (mainly as glucuronide and sulfate conjugates) accounts for approximately 60-70% of elimination; fecal/biliary excretion accounts for 30-40%.
Primarily renal as inactive metabolites; less than 5% unchanged. Biliary/fecal elimination is minimal (<2%).
