HYDROCORTISONE SODIUM PHOSPHATE vs ILUVIEN
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Hydrocortisone sodium phosphate is a corticosteroid that binds to the glucocorticoid receptor, leading to regulation of gene transcription. It inhibits phospholipase A2, reducing pro-inflammatory mediators such as prostaglandins and leukotrienes. It also suppresses immune cell migration and cytokine production.
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.
100-500 mg intravenously or intramuscularly every 2-6 hours as needed for acute conditions; typical dose 100 mg IV/IM every 8 hours.
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 approximately 1.5–2 hours; in adrenal insufficiency, dose interval is 8 hours due to HPA axis suppression considerations.
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: primarily as inactive metabolites, <1% unchanged; hepatic metabolism to tetrahydrocortisone and glucuronide conjugates; biliary/fecal excretion negligible.
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.
