Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Dexamethasone is a glucocorticoid receptor agonist, binding to the glucocorticoid receptor (GR) and modulating gene expression through transactivation and transrepression. It inhibits phospholipase A2, reduces prostaglandin and leukotriene synthesis, suppresses cytokine production (IL-1, IL-2, IL-6, TNF-alpha), and decreases immune cell migration and activation.
Hydrocortisone sodium succinate is a corticosteroid that binds to glucocorticoid receptors, modulating gene expression to produce anti-inflammatory, immunosuppressive, and anti-stress responses. It inhibits phospholipase A2, reducing prostaglandin and leukotriene synthesis.
0.5 mg orally once daily, with gradual taper to lowest effective dose
100–500 mg IV or IM every 2–6 hours, as needed; typical initial dose 100–250 mg IV bolus followed by 100–250 mg IV every 4–6 hours for acute conditions.

3.0-4.5 hours; prolonged in hepatic impairment (up to 6-8 hours) or concurrent CYP3A4 inhibitors
1.5-2 hours (plasma terminal); biological half-life 8-12 hours (due to intracellular effects), requiring q6-8h dosing in adrenal insufficiency
Renal: 70-80% (mostly as 6β-hydroxydexamethasone); biliary/fecal: 10-15%
Renal (90-95% as metabolites, <5% unchanged); biliary/fecal <5%
