EYSUVIS vs FLUOR-OP
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Eysuvis (loteprednol etabonate ophthalmic suspension) is a corticosteroid that works by inducing phospholipase A2 inhibitory proteins, collectively called lipocortins, which inhibit the release of arachidonic acid and subsequent synthesis of prostaglandins and leukotrienes, thereby reducing inflammation.
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 each eye twice daily (approximately 12 hours apart) for 4 weeks.
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.

Approximately 2-4 hours for loteprednol etabonate; clinical effect correlates with dosing interval (e.g., 4 times daily).
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.
Primarily renal (90-95% as unchanged drug and metabolites); minor biliary/fecal (<5%).
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%).
