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 corticosteroid that inhibits phospholipase A2, reducing arachidonic acid release and subsequent prostaglandin and leukotriene synthesis, thereby suppressing inflammatory responses.
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.
2 drops of 0.1% solution into the affected eye(s) every 15 minutes for 4 doses, then every 30 minutes for 2 doses, then every 1-2 hours for 24-48 hours, then tapering over 1-2 weeks; alternatively, 0.5 cm ribbon of 0.05% ointment into the conjunctival sac 4-6 times daily.

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 3-6 hours in adults with normal renal function; prolonged to 12-24 hours in severe renal impairment (CrCl <30 mL/min), necessitating dose adjustment.
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%.
Renal excretion of unchanged drug accounts for approximately 60-80% of elimination, with the remainder as metabolites (glucuronide conjugates) via urine; fecal elimination is minimal (<5%).
