BETADERM vs METI-DERM
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.
METI-DERM contains methylprednisolone aceponate, a corticosteroid that binds to glucocorticoid receptors, modulating gene expression to inhibit pro-inflammatory cytokines, phospholipase A2, and prostaglandin synthesis, thereby reducing inflammation, pruritus, and vasodilation.
Topical: Apply a thin film to affected skin twice daily; maximum 100 g per week for adults.
Apply a thin film topically to affected area once or twice daily.

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: 6–8 hours in healthy adults; prolonged to 12–15 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%.
Renal: ~60% as unchanged drug and metabolites; biliary/fecal: ~35% as metabolites and unchanged drug; minor respiratory elimination.
