PRED-G vs Prednisolone Eye Drops
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Prednisolone acetate is a glucocorticoid that suppresses inflammation by inhibiting phospholipase A2, reducing prostaglandin and leukotriene synthesis; gentamicin sulfate is an aminoglycoside antibiotic that inhibits bacterial protein synthesis by binding to 30S ribosomal subunit.
Corticosteroid that binds to glucocorticoid receptors, modulating gene expression and suppressing inflammatory mediators such as prostaglandins and leukotrienes.
1 drop of the ophthalmic suspension (containing prednisolone acetate 1% and gentamicin sulfate 0.3%) into the affected eye(s) every 2-4 hours during the day, then taper as clinical signs improve. For severe disease, 1 drop every hour initially.
Instill 1-2 drops into the conjunctival sac of the affected eye(s) four times daily. In severe cases, dosing may be initiated with 1-2 drops every 1-2 hours and tapered upon improvement.

The terminal elimination half-life of gentamicin (the active component) is approximately 2–3 hours in adults with normal renal function. In neonates, half-life is prolonged to 5–11 hours. The immunosuppressive component (prednisolone) has a half-life of 2–4 hours.
Plasma: 2-4 hours; tissue effects persist 18-36 hours. Clinically, duration of adrenal suppression may exceed plasma half-life.
Renal excretion accounts for approximately 70% of elimination, with the remainder as unchanged drug in feces (20%) and biliary excretion (10%).
Renal (primarily as metabolites): ~70% after oral dose; unchanged drug: <20%. Biliary/fecal: minor.
