A-HYDROCORT vs METICORTEN
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.
Prednisone is a prodrug that is converted to prednisolone, which binds to the glucocorticoid receptor, modulating gene expression and suppressing inflammation, immune response, and adrenal function.
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.
5-60 mg orally once daily, depending on condition; for acute exacerbations, up to 250 mg IV every 4-6 hours.

Terminal half-life: 1.5-2 hours (cortisol); clinical effect persists 8-12 hours due to glucocorticoid receptor binding
Following oral or IV administration, the terminal elimination half-life of total prednisolone (active form) is 2.1–3.5 hours in adults with normal hepatic function. In hepatic impairment, half-life may be prolonged (up to 6–8 hours), necessitating dose adjustment.
Renal (primarily as metabolites, <1% unchanged); biliary/fecal (<5%)
Primarily renal: approximately 80% as inactive metabolites (conjugated and oxidized forms) and <5% as unchanged prednisolone. Biliary/fecal excretion accounts for about 10-15% of the dose.
