DEXTENZA vs ENTOCORT EC
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
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.
Budesonide is a corticosteroid with potent glucocorticoid activity and weak mineralocorticoid activity. It binds to the glucocorticoid receptor, leading to anti-inflammatory effects via inhibition of inflammatory mediators such as cytokines and prostaglandins.
Insert 0.4 mg intracanalicularly (into the lacrimal punctum) as a single dose; releases dexamethasone over 30 days.
9 mg orally once daily in the morning for up to 8 weeks.

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.
Terminal elimination half-life is approximately 2-3 hours; clinically, the extended intestinal release formulation maintains local activity despite short systemic half-life.
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.
Primarily fecal (60-70%) with minimal renal excretion (<10%); extensively metabolized hepatically, metabolites excreted in bile and feces.
