FLORONE E vs ILUVIEN
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
FLORONE E contains diflorasone diacetate, a corticosteroid that induces phospholipase A2 inhibitory proteins (lipocortins), inhibiting arachidonic acid release and reducing prostaglandin and leukotriene synthesis, resulting in anti-inflammatory, antipruritic, and vasoconstrictive effects.
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.
Apply a thin film to affected skin area twice daily. Not for ophthalmic, oral, or intravaginal use.
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 2-4 hours (terminal) for the active moiety diflorasone; clinically, this supports twice-daily dosing for chronic skin conditions.
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 (<1% unchanged as metabolite) and biliary, with <1% excreted unchanged in urine. The remainder is metabolized and excreted in feces via bile.
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.
