DEXACORT vs YUTIQ
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Dexamethasone is a glucocorticoid receptor agonist that modulates gene expression to produce anti-inflammatory and immunosuppressive effects by inhibiting phospholipase A2, reducing prostaglandin and leukotriene synthesis, and suppressing cytokine production.
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.
Oral: 0.75-9 mg/day in divided doses; IV: 0.5-9 mg/day every 6-12 hours; IM: 4-20 mg every 2 weeks.
0.18 mg fluocinolone acetonide intravitreal implant (single administration) releasing 0.2 mcg/day over 36 months.

Plasma terminal elimination half-life is 2.8-3.5 hours in adults, but the biological half-life (duration of HPA axis suppression) is 24-36 hours due to prolonged receptor occupancy
Approximately 36 months (3 years) from the intravitreal implant; reflects sustained release from the non-biodegradable implant matrix.
Renal (approximately 80% as inactive metabolites, <5% unchanged), biliary/fecal (minor, approximately 15-20%)
Primarily hepatic/biliary; fecal excretion is the major route. Renal excretion of fluocinolone acetonide and metabolites accounts for <10%.
