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