AEROSEB-DEX vs PROCTOCORT
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.
PROCTOCORT (hydrocortisone acetate) is a corticosteroid that exerts anti-inflammatory, antipruritic, and vasoconstrictive effects. It binds to glucocorticoid receptors, modulating gene expression to inhibit phospholipase A2, reduce prostaglandin and leukotriene synthesis, and suppress cytokine production.
2 puffs (100 mcg each) intranasally twice daily
Rectal: One 30 mg suppository twice daily (morning and evening) for 2-3 weeks, then taper down as needed. Alternatively, 1% cream or ointment applied rectally 3-4 times 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 is approximately 3.5 hours (range 2-5 hours) for triamcinolone acetonide. Clinical context: short half-life supports BID or TID dosing in topical and rectal administration.
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.
Primarily hepatic metabolism; renal excretion of metabolites accounts for ~60-70%, with ~15-25% excreted in feces via biliary elimination. Unchanged drug in urine is negligible (<1%).
