AEROSEB-DEX vs BETA-HC
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.
BETA-HC (hydrocortisone) is a corticosteroid that binds to the glucocorticoid receptor, leading to modulation of gene expression and suppression of inflammatory mediators such as prostaglandins and leukotrienes. It also inhibits phospholipase A2 and reduces cytokine production.
2 puffs (100 mcg each) intranasally twice daily
1-2 tablets (200-400 mg) orally every 6-8 hours as needed for pain; not to exceed 6 tablets (1200 mg) per day.

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).
1.5 hours (beta phase); clinical context: anti-inflammatory effects persist longer than serum levels due to receptor binding and gene transcription
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 (approximately 75% as metabolites, <5% unchanged); fecal (approximately 15%)
