BETADERM vs CORTALONE
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.
Cortisone is a corticosteroid that binds to glucocorticoid receptors, modulating gene expression to suppress inflammation and immune response, and regulate metabolism.
Topical: Apply a thin film to affected skin twice daily; maximum 100 g per week for adults.
10-40 mg orally once daily in the morning; for acute exacerbations, up to 60 mg/day divided into 2-4 doses.

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 3-5 hours in patients with normal renal function; prolonged to 12-24 hours in severe renal impairment (CrCl <30 mL/min).
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 (60-70% as unchanged drug), with 10-20% biliary/fecal.
