AEROSEB-DEX vs BETADERM
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
The combination product contains a corticosteroid (dexamethasone) which suppresses inflammation by inhibiting phospholipase A2, reducing prostaglandin and leukotriene synthesis, and a topical antibiotic (usually neomycin or polymyxin B) which inhibits bacterial protein synthesis or disrupts bacterial cell membranes.
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 12-15 hours in adults with normal renal function; prolonged to 24-30 hours in severe renal impairment (CrCl <30 mL/min).
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 elimination of unchanged drug accounts for 30-40% of the dose; fecal/biliary elimination is 50-60% as metabolites. Less than 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%.
