CORTIFOAM vs DEXTENZA
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.
Dexamethasone is a corticosteroid with glucocorticoid activity that binds to the glucocorticoid receptor, leading to inhibition of inflammatory mediators such as prostaglandins and leukotrienes, and suppression of immune cell migration and activation.
1 applicatorful (90 mg hydrocortisone acetate) rectally twice daily for 2-3 weeks, then every other day as needed.
Insert 0.4 mg intracanalicularly (into the lacrimal punctum) as a single dose; releases dexamethasone over 30 days.

Approximately 1.5-2 hours for hydrocortisone; clinically, effects persist longer due to local action.
The terminal elimination half-life of dexamethasone from plasma after systemic absorption is approximately 3-4 hours. However, Dextenza provides sustained local delivery to the ocular surface; the insert releases dexamethasone over 30 days, with therapeutic levels maintained throughout.
Primarily renal (about 70-90% as metabolites) and fecal (about 10-30% as metabolites).
Dextenza (dexamethasone ophthalmic insert) is administered intracanalicularly; systemic absorption is minimal. Following release into the tear film, the drug is primarily eliminated via nasolacrimal drainage and subsequent gastrointestinal absorption with hepatic metabolism. Renal excretion accounts for <5% of the dose as unchanged drug; biliary/fecal elimination is negligible.
