FLUOR-OP vs PRED MILD
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Fluorometholone is a corticosteroid that inhibits phospholipase A2, reducing arachidonic acid release and subsequent prostaglandin and leukotriene synthesis, thereby suppressing inflammatory responses.
Prednisolone acetate is a corticosteroid that binds to the glucocorticoid receptor, leading to inhibition of phospholipase A2 and reduction of inflammatory mediators such as prostaglandins and leukotrienes.
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.
1 to 2 drops in the affected eye(s) every hour during the day and every 2 hours at night until a favorable response is obtained, then reduce to 1 drop every 4 hours, and later to 1 drop 3 to 4 times daily as needed to control symptoms.

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.
The terminal elimination half-life of prednisolone is approximately 2.1-3.5 hours. Clinically, this short half-life supports once-daily dosing for many conditions, with minimal accumulation upon repeated administration.
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%).
Prednisolone is primarily excreted renally, with approximately 70-80% of the dose eliminated as metabolites in urine (including glucuronides and sulfates) and less than 10% as unchanged drug. Biliary/fecal excretion accounts for about 20% of the dose.
