CORTISONE ACETATE vs DEXTENZA
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Corticosteroid with glucocorticoid and mineralocorticoid activity; binds to glucocorticoid receptors, modulating gene expression to suppress inflammation and immune responses.
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.
25-300 mg per day orally, in divided doses every 6-12 hours, depending on condition severity.
Insert 0.4 mg intracanalicularly (into the lacrimal punctum) as a single dose; releases dexamethasone over 30 days.

Clinical Note
moderate30 minutes (plasma half-life of cortisol); biological half-life 8-12 hours (due to intracellular receptor binding and transcriptional effects)
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 (approximately 90% as metabolites, <5% unchanged); biliary/fecal (<5%)
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.
