Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Dexamethasone sodium phosphate is a corticosteroid with potent anti-inflammatory and immunosuppressant properties. It binds to the glucocorticoid receptor, leading to modulation of gene expression and suppression of pro-inflammatory cytokines, inhibition of phospholipase A2, and reduction of inflammatory mediators like prostaglandins and leukotrienes.
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.
0.5-24 mg/day IV or IM in divided doses every 6-12 hours; acute conditions: 4-20 mg IV initially, then 2-4 mg every 4-6 hours.
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).

Terminal elimination half-life is 3-4 hours in adults; clinical context: biological effects persist >24 hours due to prolonged receptor binding.
Terminal elimination half-life: 1.5–2.5 hours (plasma), but biological half-life (duration of HPA axis suppression) is 8–12 hours.
Primarily renal (approximately 65-80% as free steroid and glucuronide conjugates); minor biliary/fecal elimination (10-15%).
Renal (primarily as inactive metabolites; <5% unchanged) and biliary/fecal (minor).
