DEXACORT vs FLORONE E
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Dexamethasone is a glucocorticoid receptor agonist that modulates gene expression to produce anti-inflammatory and immunosuppressive effects by inhibiting phospholipase A2, reducing prostaglandin and leukotriene synthesis, and suppressing cytokine production.
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.
Oral: 0.75-9 mg/day in divided doses; IV: 0.5-9 mg/day every 6-12 hours; IM: 4-20 mg every 2 weeks.
Apply a thin film to affected skin area twice daily. Not for ophthalmic, oral, or intravaginal use.

Plasma terminal elimination half-life is 2.8-3.5 hours in adults, but the biological half-life (duration of HPA axis suppression) is 24-36 hours due to prolonged receptor occupancy
Approximately 2-4 hours (terminal) for the active moiety diflorasone; clinically, this supports twice-daily dosing for chronic skin conditions.
Renal (approximately 80% as inactive metabolites, <5% unchanged), biliary/fecal (minor, approximately 15-20%)
Primarily renal (<1% unchanged as metabolite) and biliary, with <1% excreted unchanged in urine. The remainder is metabolized and excreted in feces via bile.
