CORTIFOAM vs FLONASE ALLERGY RELIEF
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Cortifoam (hydrocortisone acetate) is a corticosteroid that binds to glucocorticoid receptors, modulating gene expression to induce anti-inflammatory, antipruritic, and vasoconstrictive effects. It inhibits phospholipase A2, reducing prostaglandin and leukotriene synthesis, and suppresses immune cell migration and cytokine release.
Glucocorticoid agonist; binds to glucocorticoid receptors, inhibiting inflammatory mediators (e.g., cytokines, prostaglandins) and reducing nasal mucosal inflammation.
1 applicatorful (90 mg hydrocortisone acetate) rectally twice daily for 2-3 weeks, then every other day as needed.
2 sprays (50 mcg each) per nostril once daily, total daily dose 200 mcg. If inadequate, may increase to 2 sprays per nostril twice daily (400 mcg/day).

Approximately 1.5-2 hours for hydrocortisone; clinically, effects persist longer due to local action.
Terminal elimination half-life is approximately 10 hours (range 7–14 hours), reflecting slow release from tissue binding sites; accumulation occurs with once-daily dosing, achieving steady state in 1–2 weeks.
Primarily renal (about 70-90% as metabolites) and fecal (about 10-30% as metabolites).
Primarily hepatic metabolism via CYP3A4; renal excretion accounts for <5% as unchanged drug, with the remainder as metabolites in feces (approximately 90%) and urine (approximately 5%).
