AEROSEB-DEX vs FLUOCINONIDE EMULSIFIED BASE
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.
Fluocinonide is a corticosteroid that binds to the glucocorticoid receptor, leading to inhibition of phospholipase A2, reduction of prostaglandin and leukotriene synthesis, and suppression of inflammatory mediators. In an emulsified base, it enhances penetration and local anti-inflammatory activity.
2 puffs (100 mcg each) intranasally twice daily
Apply a thin film to affected area once to twice daily. Topical use only. Maximum duration of continuous use is 2 weeks. Total dosage should not exceed 60 g per week.

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).
The terminal elimination half-life of fluocinonide is approximately 1-2 hours after topical administration, reflecting rapid systemic clearance. This short half-life minimizes systemic accumulation with once- or twice-daily dosing.
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.
Fluocinonide is primarily metabolized in the liver, and its metabolites are excreted via the kidneys (approximately 60-70%) and feces (30-40%). No unchanged drug is excreted.
