FLOVENT DISKUS 250 vs ILUVIEN
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Fluticasone propionate is a corticosteroid with potent anti-inflammatory activity. It binds to the glucocorticoid receptor, leading to inhibition of pro-inflammatory cytokines, reduction of eosinophil recruitment, and suppression of airway hyperresponsiveness.
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.
250 mcg inhaled orally via DISKUS twice daily (500 mcg total daily dose).
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.

Approximately 10-12 hours (terminal elimination half-life in asthmatics).
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.
Renal (approximately 5% as unchanged drug); fecal (majority as metabolites and unabsorbed drug).
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.
