Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Hydrocortisone sodium phosphate is a corticosteroid that binds to the glucocorticoid receptor, leading to regulation of gene transcription. It inhibits phospholipase A2, reducing pro-inflammatory mediators such as prostaglandins and leukotrienes. It also suppresses immune cell migration and cytokine production.
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.
100-500 mg intravenously or intramuscularly every 2-6 hours as needed for acute conditions; typical dose 100 mg IV/IM every 8 hours.
5-60 mg orally once daily, depending on condition; for acute exacerbations, up to 250 mg IV every 4-6 hours.

Terminal elimination half-life approximately 1.5–2 hours; in adrenal insufficiency, dose interval is 8 hours due to HPA axis suppression considerations.
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 inactive metabolites, <1% unchanged; hepatic metabolism to tetrahydrocortisone and glucuronide conjugates; biliary/fecal excretion negligible.
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.
