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.
Corticosteroid with anti-inflammatory and immunosuppressive properties; suppresses multiple inflammatory cytokines and induces lipocortin synthesis.
Insert 0.4 mg intracanalicularly (into the lacrimal punctum) as a single dose; releases dexamethasone over 30 days.
Intravenous: Initial dose 100-250 mg, then repeat every 10-30 minutes as needed. Intramuscular: 100-250 mg every 10-30 minutes. Intra-articular: 10-40 mg per joint every 1-2 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 half-life ~2-3 hours; clinically, adrenal suppression may persist >24h.
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.
Renally eliminated: ~80% as metabolites, <10% unchanged. Biliary/fecal: minor.
