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.
Solu-Cortef (hydrocortisone sodium succinate) is a corticosteroid that binds to the glucocorticoid receptor, leading to modulation of gene expression and suppression of inflammatory mediators, including prostaglandins and leukotrienes. It also inhibits immune cell migration and activation.
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.
100-1000 mg intravenous (IV) or intramuscular (IM), then 100-500 mg IV or IM every 2-6 hours as needed.

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: 1.5-2 hours (hydrocortisone); clinical duration of action is longer due to genomic effects (6-8 hours).
Renal (approximately 80% as inactive metabolites, <5% unchanged), biliary/fecal (minor, approximately 15-20%)
Renal: ~80% as metabolites (mainly 17-hydroxycorticosteroids) and <5% unchanged. Biliary/fecal: minimal (<5%).
