OPHTHOCORT vs PEDIAZOLE
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.
Pediazole is a combination of erythromycin (a macrolide antibiotic that binds to the 50S ribosomal subunit, inhibiting bacterial protein synthesis) and sulfisoxazole (a sulfonamide that inhibits dihydropteroate synthase, blocking folic acid synthesis).
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.
Adults: 1 mg/kg intravenously every 6 hours.

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).
Terminal half-life is approximately 6-8 hours in adults with normal renal function; prolonged to 20-40 hours in severe renal impairment.
Renal (70-80% as unchanged drug), fecal (15-20% via biliary elimination), with minor metabolic clearance.
Renal excretion of unchanged drug accounts for approximately 70-80% of the dose; biliary/fecal elimination is minor (<10%).
