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.
Fluorometholone is a synthetic corticosteroid that binds to the glucocorticoid receptor, leading to inhibition of phospholipase A2, decreased release of arachidonic acid, and reduced synthesis of prostaglandins and leukotrienes. This results in suppression of inflammation, immune response, and fibroblast proliferation.
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 drop of 0.25% ophthalmic suspension in the conjunctival sac of the affected eye(s) every 4 hours. In severe conditions, 1 drop every 2 hours initially, taper as response is achieved.

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.
Plasma terminal elimination half-life is approximately 3-4 hours (range 2-6 hours) for fluorometholone alcohol; clinical effects may persist longer due to tissue retention.
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%.
Eliminated primarily via hepatic metabolism; renal excretion of inactive metabolites accounts for approximately 60-70%, with about 30-40% excreted in feces via bile.
