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 glucocorticoid that binds to the glucocorticoid receptor, altering gene expression to produce anti-inflammatory and immunosuppressive effects.
10-60 mg orally once daily in the morning, gradually tapered as tolerated. Maintenance dose 5-10 mg orally once daily.
0.5-1.5 mL (5-15 mg prednisolone equivalent) injected subconjunctivally or peribulbarly as a single dose; may repeat weekly if needed. For systemic use, 5-60 mg/day oral prednisolone equivalent, divided 1-2 times daily.

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 of prednisolone is approximately 2-4 hours in adults. In children, the half-life may be shorter (1-3 hours). The half-life can be prolonged in patients with hepatic impairment or severe renal disease. This short half-life allows for alternate-day dosing to minimize hypothalamic-pituitary-adrenal (HPA) axis suppression.
Renal: 75-90% as unchanged drug; Biliary/Fecal: 10-25% as metabolites and unchanged drug.
Prednisolone (active metabolite of prednisone) is eliminated primarily via renal excretion of inactive metabolites (approximately 80-90%) and to a minor extent via fecal excretion (approximately 10-20%). Less than 1% of the dose is excreted unchanged in urine.
