DELTA-CORTEF vs DEXTENZA
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Glucocorticoid; binds to glucocorticoid receptors, modulating gene expression to suppress inflammation, immune response, and adrenal function.
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.
Prednisolone (DELTA-CORTEF) typical adult dose: 5-60 mg orally once daily or in divided doses, depending on condition. For acute exacerbations: 20-60 mg orally daily. Route: oral. Frequency: once daily or divided.
Insert 0.4 mg intracanalicularly (into the lacrimal punctum) as a single dose; releases dexamethasone over 30 days.

Terminal elimination half-life: 1.5-2.5 hours (mean ~2 hours) for prednisolone; clinical context: short-acting glucocorticoid, requires multiple daily dosing for sustained anti-inflammatory effect, adrenocortical suppression lasts approximately 1.25-1.5 days after discontinuation.
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 80-90% as unchanged drug and metabolites (primarily 20β-dihydrocortisone and other inactive conjugates); biliary/fecal: <10%.
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.
