DRICORT vs ILUVIEN
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Corticosteroid with predominant glucocorticoid activity; binds to glucocorticoid receptors, modulating gene expression and suppressing inflammatory mediators (e.g., prostaglandins, leukotrienes) and immune cell function.
Fluocinolone acetonide, a corticosteroid, suppresses inflammation by inhibiting phospholipase A2, reducing arachidonic acid release and subsequent prostaglandin and leukotriene synthesis. It also inhibits cytokine production and endothelial cell adhesion molecule expression.
DRICORT (dexamethasone) typical adult dose: 0.5-9 mg/day orally in divided doses every 6-12 hours, or 0.5-24 mg IV/IM once or divided. Anti-inflammatory: 0.75-9 mg/day PO/IV in 2-4 divided doses. Severe conditions: up to 16 mg/day in divided doses. Short-term high-dose: up to 40-100 mg IV push for specific indications.
Intravitreal implant containing 0.19 mg fluocinolone acetonide, designed to release drug over approximately 36 months. Administered as a single injection into the vitreous cavity of the eye.

Terminal elimination half-life is 10-12 hours in adults with normal renal function, allowing twice-daily dosing.
Intravitreal terminal half-life of fluocinolone acetonide from the Iluvien implant is approximately 30 months (range 18-36 months), providing sustained release over 36 months in the vitreous cavity.
Primarily renal (80-85% as unchanged drug and metabolites), with 15-20% excreted in feces via biliary elimination.
Fluocinolone acetonide is primarily eliminated via hepatic metabolism and subsequent fecal/biliary excretion. Approximately 50-70% of a dose is excreted in feces as metabolites, with less than 20% recovered in urine as unchanged drug or metabolites.
