Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
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.
Adrenocorticosteroid; binds to glucocorticoid receptor, modulating gene expression to produce anti-inflammatory, immunosuppressive, and metabolic effects.
5-60 mg orally once daily, depending on condition; for acute exacerbations, up to 250 mg IV every 4-6 hours.
10-20 mg orally once daily

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.
2-3 h. The terminal elimination half-life is short, requiring thrice-daily dosing for sustained effect. Context: In patients with hepatic impairment, half-life may be prolonged up to 4-5 h.
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.
Primarily hepatic metabolism (>90%) with renal excretion of inactive metabolites (approximately 80% in urine, 20% in feces). Less than 5% of the parent drug is excreted unchanged in urine.
