Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Hydrocortisone is a glucocorticoid that binds to the glucocorticoid receptor, leading to modulation of gene transcription. It inhibits phospholipase A2, reducing prostaglandin and leukotriene synthesis; suppresses inflammatory cytokine production; and causes vasoconstriction and immunosuppression.
Prednisolone is a synthetic glucocorticoid that binds to the glucocorticoid receptor, modulating gene transcription to suppress inflammation, immune response, and adrenal function.
Hydrocortisone 100-500 mg IV/IM every 2-6 hours as needed for acute adrenal insufficiency or severe inflammation. Maintenance: 20-30 mg/day PO divided every 8-12 hours.
20-40 mg intramuscularly every 3 weeks; for intra-articular use: 20-40 mg per large joint, 10-20 mg per medium joint, 4-10 mg per small joint.

1.5–2.5 hours (terminal half-life). In clinical context, the biological half-life (duration of HPA suppression) is longer (8–12 hours) due to tissue binding and active metabolites.
Plasma t1/2 ~2.5-3.5 hours. Duration of adrenal suppression may persist for 24-48 hours.
Renal: predominantly as conjugated metabolites and a small fraction of unchanged drug. Biliary/fecal: minor, <5%. Total renal clearance accounts for >95% of elimination.
Primarily renal (80-90% as inactive metabolites and unchanged drug). Biliary excretion accounts for <5%.
