OPHTHOCORT vs PRED FORTE
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
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.
Corticosteroid that binds to glucocorticoid receptors, causing inhibition of phospholipase A2, arachidonic acid release, and synthesis of inflammatory mediators. Reduces inflammation by suppressing leukocyte infiltration and cytokine production.
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.
1-2 drops in the conjunctival sac every 1-2 hours during the day and every 4 hours at night initially, then taper to every 4-8 hours as inflammation resolves. Severe cases may require hourly dosing.

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).
2-3 hours (terminal) after IV administration; for topical ophthalmic use, systemic half-life is similar but local ocular half-life is prolonged due to corneal reservoir.
Renal (70-80% as unchanged drug), fecal (15-20% via biliary elimination), with minor metabolic clearance.
Primarily hepatic metabolism; renal excretion of inactive metabolites accounts for approximately 80% of elimination, with biliary/fecal elimination <20%.
