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.
Topical corticosteroid that binds to glucocorticoid receptors, modulating gene expression to inhibit phospholipase A2, reduce prostaglandin and leukotriene synthesis, and suppress cytokine release, thereby exerting anti-inflammatory, antipruritic, and vasoconstrictive effects.
Topical: Apply a thin film to affected skin twice daily; maximum 100 g per week for adults.
Topical: Apply a thin film to affected area 2-4 times daily. Rectal: Insert one suppository (25 mg) rectally twice daily (morning and evening) for 2-3 weeks, then taper as needed.

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.
Terminal elimination half-life is 1.5-2.5 hours; clinical duration of action is longer due to genomic effects lasting 8-12 hours.
Renal excretion of metabolites (mainly as glucuronide and sulfate conjugates) accounts for approximately 60-70% of elimination; fecal/biliary excretion accounts for 30-40%.
Renal (approximately 70% as inactive metabolites, <5% unchanged); fecal (approximately 30%)
