Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Corticosteroid that binds to the glucocorticoid receptor, leading to altered gene expression and inhibition of inflammatory mediators such as prostaglandins and leukotrienes.
Prednisolone is a corticosteroid that binds to the glucocorticoid receptor, leading to inhibition of phospholipase A2, decreased production of prostaglandins and leukotrienes, and suppression of cytokine release.
Hydrocortisone (Cortef) 10-30 mg orally 2-4 times daily; for anti-inflammatory effect: 20-240 mg orally daily in divided doses; for physiologic replacement: 20-30 mg orally daily in divided doses (e.g., 10 mg morning, 5 mg afternoon).
Initial adult dose: 40-60 mg orally once daily; maintenance: 5-60 mg orally once daily; dose individualized based on disease severity and response.

Plasma terminal half-life: 1.5–2.5 hours (cortisol); duration of action: 8–12 hours due to intracellular effects.
The terminal elimination half-life is 2-4 hours in adults; prolonged in hepatic impairment (up to 8-12 hours).
Renal (primarily as inactive metabolites, <5% unchanged); biliary/fecal (minor).
Prednisolone is primarily metabolized in the liver; renal excretion accounts for <1% unchanged. Metabolites are excreted renally (~60-70%) and in bile/feces (~20-30%).
