Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Glucocorticoid receptor agonist; suppresses inflammation and immune responses by inhibiting phospholipase A2, reducing prostaglandin and leukotriene synthesis, and modulating gene transcription.
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.
Oral: Initial dose 50-100 mg twice daily; maintenance 25-50 mg twice daily. Maximum 200 mg/day.
5-60 mg orally once daily, depending on condition; for acute exacerbations, up to 250 mg IV every 4-6 hours.

Terminal elimination half-life: 2.6-3.8 hours. Clinical context: Short half-life requires multiple daily dosing; no significant accumulation with regular dosing.
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.
Renal: 20-30% as unchanged drug; biliary/fecal: 70-80% as metabolites and unchanged drug.
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.
