FLUOR-OP vs OPHTHOCORT
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.
OPHTHOCORT contains chloramphenicol, a bacteriostatic antibiotic that inhibits bacterial protein synthesis by binding to the 50S ribosomal subunit, preventing peptide bond formation; and hydrocortisone, a corticosteroid that suppresses inflammation by inhibiting phospholipase A2 and reducing prostaglandin and leukotriene synthesis.
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.
One drop into the affected eye(s) every 3-4 hours, or more frequently as needed. In severe cases, one drop every hour. Shake well before use.

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.
Terminal elimination half-life: 2.5-3.5 hours in adults with normal renal function; prolonged to 12-24 hours in severe renal impairment (CrCl <30 mL/min).
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%).
Renal (70-80% as unchanged drug), fecal (15-20% via biliary elimination), with minor metabolic clearance.
