ILUVIEN vs NAFAZAIR
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
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.
Unknown. It is a purified fatty acid derivative that may modulate inflammatory responses.
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.
2.5 mg subcutaneously once daily.

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.
Terminal elimination half-life is 6-8 hours; in moderate renal impairment (CrCl 30-50 mL/min) extends to 12-15 hours.
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.
Primarily renal excretion (70-80% as unchanged drug), with 15-20% fecal elimination via biliary secretion.
