A-HYDROCORT vs DECADRON
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Hydrocortisone is a corticosteroid hormone that binds to glucocorticoid receptors, modulating gene expression to suppress inflammation, inhibit immune response, and regulate metabolism.
Dexamethasone is a glucocorticoid receptor agonist, binding to the glucocorticoid receptor and modulating gene expression to produce anti-inflammatory and immunosuppressive effects. It also suppresses adrenal function by inhibiting ACTH secretion.
Adrenal insufficiency: oral 20-30 mg/day in divided doses; inflammatory conditions: 5-60 mg/day oral; IV/IM: hydrocortisone sodium succinate 50-100 mg every 4-6 hours.
0.75-9 mg/day orally in divided doses every 6-12 hours; or 0.5-9 mg/day IM/IV in divided doses every 12 hours for acute conditions; for cerebral edema, IV loading dose of 10 mg followed by 4 mg IM/IV every 6 hours.

Terminal half-life: 1.5-2 hours (cortisol); clinical effect persists 8-12 hours due to glucocorticoid receptor binding
Terminal half-life: 3-4 hours (plasma); biological half-life: 36-54 hours (due to intracellular receptor binding); clinical context: duration of HPA axis suppression longer than plasma half-life
Renal (primarily as metabolites, <1% unchanged); biliary/fecal (<5%)
Renal (65-80% as 17-hydroxycorticosteroids and 20-hydroxycorticosteroids after hepatic metabolism); biliary/fecal (minor, <10%)
