CUTIVATE vs DEXTENZA
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Glucocorticoid receptor agonist; modulates gene expression to inhibit inflammatory mediators, vasoconstriction, and immunosuppression.
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.
Apply a thin layer to affected skin areas once or twice daily. Therapy should be discontinued when control is achieved; if no improvement is seen within 2 weeks, reassessment of diagnosis may be necessary.
Insert 0.4 mg intracanalicularly (into the lacrimal punctum) as a single dose; releases dexamethasone over 30 days.

2-4 hours (terminal elimination half-life); short half-life supports twice-daily dosing for maintenance of clinical effect.
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.
Primarily hepatic metabolism; metabolites are excreted renally and fecally. Unchanged drug is negligible in urine. Route: renal (~60% as metabolites), fecal (~40% as metabolites).
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.
