DEXACEN-4 vs HYDROCORTONE
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Dexamethasone is a glucocorticoid receptor agonist that binds to the glucocorticoid receptor, leading to increased transcription of anti-inflammatory proteins and suppression of pro-inflammatory mediators.
Hydrocortisone is a corticosteroid that binds to the glucocorticoid receptor, leading to anti-inflammatory and immunosuppressive effects by inhibiting phospholipase A2, reducing prostaglandin and leukotriene synthesis, and suppressing cytokine production.
Dexamethasone 4 mg orally or intravenously every 6-8 hours; typical adult dose is 4-20 mg/day in divided doses, depending on condition.
100-500 mg intravenously every 2-6 hours for initial management of adrenal insufficiency; oral maintenance: 20-30 mg daily in divided doses (e.g., 10 mg morning, 5 mg afternoon).

3-4 hours; prolonged to 6-8 hours in renal impairment (CrCl <30 mL/min)
Terminal elimination half-life: 1.5–2.5 hours (plasma), but biological half-life (duration of HPA axis suppression) is 8–12 hours.
Renal: 65-80% as unchanged drug; Biliary: 10-15% as metabolites; Fecal: <5%
Renal (primarily as inactive metabolites; <5% unchanged) and biliary/fecal (minor).
