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, leading to anti-inflammatory and immunosuppressive effects via modulation of gene expression.
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.
10-60 mg orally once daily in the morning, gradually tapered as tolerated. Maintenance dose 5-10 mg orally once daily.
Initial adult dose: 40-60 mg orally once daily; maintenance: 5-60 mg orally once daily; dose individualized based on disease severity and response.

3-4 hours (terminal) in patients with normal renal function; prolonged to 12-24 hours in severe renal impairment (CrCl <30 mL/min).
The terminal elimination half-life is 2-4 hours in adults; prolonged in hepatic impairment (up to 8-12 hours).
Renal: 75-90% as unchanged drug; Biliary/Fecal: 10-25% as metabolites and unchanged drug.
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%).
