Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Erythromycin acts by binding to the 50S subunit of the bacterial ribosome, inhibiting protein synthesis by blocking the translocation step.
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.
Adults: 500 mg orally once daily for 3 consecutive days per month.
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.

Terminal elimination half-life is 4-6 hours in patients with normal renal function (creatinine clearance >60 mL/min). In severe renal impairment (CrCl <30 mL/min), half-life may extend to 12-18 hours.
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.
Renal excretion of unchanged drug accounts for approximately 75% of the dose; fecal elimination is about 20%, with the remainder as biliary metabolites.
Renal excretion accounts for approximately 70% of elimination, with the remainder as unchanged drug in feces (20%) and biliary excretion (10%).
