DEXACORT vs FLORONE
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.
Glucocorticoid receptor agonist; induces phospholipase A2 inhibitory proteins (lipocortins), which suppress release of arachidonic acid and subsequent prostaglandin/leukotriene synthesis; also suppresses cytokine production and immune cell migration.
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.
Topical: Apply a thin layer to affected skin once or twice daily. Maximum use: 45 g/week.

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
Terminal elimination half-life of approximately 2-3 hours; clinical context: duration of action may extend beyond half-life due to tissue binding.
Renal (approximately 80% as inactive metabolites, <5% unchanged), biliary/fecal (minor, approximately 15-20%)
Renal (approximately 80% as metabolites, <5% unchanged), biliary/fecal (remainder).
