Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Prednisolone acetate is a corticosteroid that binds to glucocorticoid receptors, modulating gene expression to reduce inflammation, immune response, and vascular permeability.
Corticosteroid that inhibits phospholipase A2 activity, reducing arachidonic acid release and subsequent production of prostaglandins and leukotrienes, thereby suppressing ocular inflammation.
1 drop in the affected eye(s) every 1-2 hours during the day and every 2 hours at night until clinical response, then reduce frequency to 1 drop every 4 hours, then 1 drop 3-4 times daily. Ophthalmic suspension, 1% prednisolone acetate equivalent.
1-2 drops in the conjunctival sac every hour during the day and every 2 hours at night initially; after response, reduce to 1 drop every 4 hours, then 1 drop 3-4 times daily. Ophthalmic suspension.

Terminal elimination half-life is approximately 2-4 hours for prednisolone. However, the biological half-life (duration of adrenal suppression) is 24-36 hours due to intracellular receptor binding and slow dissociation.
Terminal elimination half-life is approximately 1-2 hours (mean 1.3 hours) in adults. Due to rapid clearance, accumulation is minimal with topical ophthalmic dosing, but prolonged use may lead to systemic absorption and slightly extended half-life.
Prednisolone is primarily metabolized in the liver; metabolites are excreted renally. Approximately 60-70% of a dose is excreted in urine as metabolites, with less than 10% as unchanged drug. Fecal excretion accounts for 10-15%.
Primarily hepatic metabolism, with inactive metabolites excreted renally (approximately 60-80%) and fecally (20-40%). Less than 5% of unchanged drug appears in urine.
