DEXACEN-4 vs H-CORT
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.
H-CORT (hydrocortisone) is a corticosteroid with glucocorticoid and mineralocorticoid activity. It 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.
Intravenous: 100-250 mg as a single dose or up to 1 gram daily for acute conditions. Oral: 20-30 mg daily in divided doses. Maintenance: 5-20 mg daily.

3-4 hours; prolonged to 6-8 hours in renal impairment (CrCl <30 mL/min)
Terminal elimination half-life: 1.5-2 hours. Clinical context: Short half-life requires q4-6h dosing; duration may be prolonged in hepatic impairment.
Renal: 65-80% as unchanged drug; Biliary: 10-15% as metabolites; Fecal: <5%
Renal: ~80% as metabolites, ~5% unchanged; biliary/fecal: ~15%
