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.
Synthetic corticosteroid with potent glucocorticoid activity; binds to glucocorticoid receptors, modulating gene expression to suppress inflammation, immune response, and adrenal function.
5-60 mg orally once daily, depending on condition; for acute exacerbations, up to 250 mg IV every 4-6 hours.
100 mg intravenously every 8 hours for 24 hours, then 50 mg intravenously every 8 hours for 48 hours, followed by 25 mg intravenously every 8 hours for 72 hours.

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.
Terminal elimination half-life is 2.5–3.5 hours; clinically, this short half-life requires multiple daily dosing for sustained effects.
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 renal (80% as metabolites, 20% unchanged); minor biliary/fecal (<5%).
