ACTICORT vs DEXTENZA
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Topical corticosteroid with anti-inflammatory, antipruritic, and vasoconstrictive actions. Suppresses cytokine production and inflammatory mediators via glucocorticoid receptor binding.
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.
5-60 mg orally once daily, or divided twice daily, depending on condition severity and response.
Insert 0.4 mg intracanalicularly (into the lacrimal punctum) as a single dose; releases dexamethasone over 30 days.

1.5-2.5 hours; prolonged in hepatic impairment (up to 10 hours) and renal impairment (up to 6 hours)
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.
Renal (70% as unchanged drug and metabolites), biliary/fecal (30%)
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.
