Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Prednisolone is a glucocorticoid that binds to the glucocorticoid receptor, altering gene expression to produce anti-inflammatory and immunosuppressive effects.
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.
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.
Initial adult dose: 40-60 mg orally once daily; maintenance: 5-60 mg orally once daily; dose individualized based on disease severity and response.

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.
The terminal elimination half-life is 2-4 hours in adults; prolonged in hepatic impairment (up to 8-12 hours).
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.
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%).
