Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Dexamethasone sodium phosphate is a glucocorticoid that binds to the glucocorticoid receptor, leading to anti-inflammatory and immunosuppressive effects by inhibiting phospholipase A2, reducing prostaglandin and leukotriene synthesis, and modulating gene expression.
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.
4-20 mg IV or IM every 4-6 hours; for cerebral edema: 10 mg IV followed by 4 mg IM/IV every 6 hours; for shock: 20 mg IV initially then 2-6 mg/kg IV bolus or 40 mg IV every 2-6 hours as needed.
100-1000 mg intravenous (IV) or intramuscular (IM), then 100-500 mg IV or IM every 2-6 hours as needed.

Terminal elimination half-life is 3-4 hours in adults; however, the duration of action extends beyond the plasma half-life due to intracellular receptor-mediated effects.
Terminal elimination half-life: 1.5-2 hours (hydrocortisone); clinical duration of action is longer due to genomic effects (6-8 hours).
Renal excretion of unchanged drug and metabolites accounts for approximately 60-70% of elimination; biliary/fecal excretion accounts for 30-40%.
Renal: ~80% as metabolites (mainly 17-hydroxycorticosteroids) and <5% unchanged. Biliary/fecal: minimal (<5%).
