AEROSEB-DEX vs LIDEX
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.
Glucocorticoid receptor agonist; inhibits phospholipase A2, reducing prostaglandin and leukotriene synthesis; suppresses inflammatory cytokines and immune cell migration.
2 puffs (100 mcg each) intranasally twice daily

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: 28-36 hours. Clinical context: Steady-state achieved in ~5-7 days; once-daily dosing maintains therapeutic levels without accumulation in patients with normal renal function.
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 (primarily as metabolites) ~ 95%; biliary/fecal ~5%.
