CORTONE vs YUTIQ
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Cortisone is a corticosteroid that binds to glucocorticoid receptors, leading to decreased inflammation through inhibition of phospholipase A2, reduced cytokine production, and suppression of immune cell migration.
YUTIQ (fluocinolone acetonide intravitreal implant) is a corticosteroid that binds to glucocorticoid receptors, leading to inhibition of phospholipase A2, suppression of arachidonic acid release, and downregulation of pro-inflammatory mediators such as prostaglandins, leukotrienes, and cytokines. This reduces inflammation and vascular permeability in the eye.
Oral: 25-300 mg daily in 1-4 divided doses; typical initial dose 150-300 mg daily. IM/IV: 100-500 mg every 6-12 hours.
0.18 mg fluocinolone acetonide intravitreal implant (single administration) releasing 0.2 mcg/day over 36 months.

Terminal half-life: 8-12 hours (cortisone) but cortisone is a prodrug; active metabolite cortisol has half-life 1.5-2 hours. Clinical context: duration of action 8-12 hours due to prolonged receptor occupancy.
Approximately 36 months (3 years) from the intravitreal implant; reflects sustained release from the non-biodegradable implant matrix.
Renal: ~90% as metabolites (glucuronides and sulfates), ~5% unchanged; biliary/fecal: ~5%.
Primarily hepatic/biliary; fecal excretion is the major route. Renal excretion of fluocinolone acetonide and metabolites accounts for <10%.
