PEDIAZOLE vs PRED-G
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
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).
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: 1 mg/kg intravenously every 6 hours.
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 half-life is approximately 6-8 hours in adults with normal renal function; prolonged to 20-40 hours in severe renal impairment.
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 70-80% of the dose; biliary/fecal elimination is minor (<10%).
Renal excretion accounts for approximately 70% of elimination, with the remainder as unchanged drug in feces (20%) and biliary excretion (10%).
