HYDELTRA-TBA vs HYDROCORTONE
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Prednisolone is a synthetic glucocorticoid that binds to the glucocorticoid receptor, modulating gene transcription to suppress inflammation, immune response, and adrenal function.
Hydrocortisone is a corticosteroid that binds to the glucocorticoid receptor, leading to anti-inflammatory and immunosuppressive effects by inhibiting phospholipase A2, reducing prostaglandin and leukotriene synthesis, and suppressing cytokine production.
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.
100-500 mg intravenously every 2-6 hours for initial management of adrenal insufficiency; oral maintenance: 20-30 mg daily in divided doses (e.g., 10 mg morning, 5 mg afternoon).

Plasma t1/2 ~2.5-3.5 hours. Duration of adrenal suppression may persist for 24-48 hours.
Terminal elimination half-life: 1.5–2.5 hours (plasma), but biological half-life (duration of HPA axis suppression) is 8–12 hours.
Primarily renal (80-90% as inactive metabolites and unchanged drug). Biliary excretion accounts for <5%.
Renal (primarily as inactive metabolites; <5% unchanged) and biliary/fecal (minor).
