Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Betamethasone is a corticosteroid that binds to the glucocorticoid receptor, leading to anti-inflammatory and immunosuppressive effects by inhibiting phospholipase A2, reducing prostaglandin and leukotriene synthesis, and modulating gene expression.
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.

Terminal elimination half-life is approximately 12-15 hours in adults with normal renal function. In patients with creatinine clearance <30 mL/min, half-life may extend to 30-40 hours, requiring dose adjustment.
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.
Renal excretion of unchanged drug accounts for 60-80% of the dose. Hepatic metabolism produces inactive metabolites, with approximately 15-25% eliminated via bile and feces. A small fraction (5-10%) is excreted unchanged in feces.
Renal excretion of metabolites (mainly as glucuronide and sulfate conjugates) accounts for approximately 60-70% of elimination; fecal/biliary excretion accounts for 30-40%.
