DEXTENZA vs YUTIQ
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.
YUTIQ (fluocinolone acetonide intravitreal implant) is a corticosteroid that binds to glucocorticoid receptors, leading to inhibition of phospholipase A2, suppression of arachidonic acid release, and downregulation of pro-inflammatory mediators such as prostaglandins, leukotrienes, and cytokines. This reduces inflammation and vascular permeability in the eye.
Insert 0.4 mg intracanalicularly (into the lacrimal punctum) as a single dose; releases dexamethasone over 30 days.
0.18 mg fluocinolone acetonide intravitreal implant (single administration) releasing 0.2 mcg/day over 36 months.

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.
Approximately 36 months (3 years) from the intravitreal implant; reflects sustained release from the non-biodegradable implant matrix.
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 hepatic/biliary; fecal excretion is the major route. Renal excretion of fluocinolone acetonide and metabolites accounts for <10%.
