KERLEDEX vs PRED-G
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Kerledex is a selective serotonin reuptake inhibitor (SSRI) that potentiates serotonergic activity in the CNS by inhibiting the reuptake of serotonin at the presynaptic neuronal membrane.
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.
Intravenous: 500 mg every 6 hours; Oral: 250 mg every 8 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 12 hours (range 10–14) in normal renal function; extended to 30–50 hours in severe renal impairment (CrCl <30 mL/min); 6–8 hours in hepatic cirrhosis.
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: 70% unchanged; fecal/biliary: 20% as metabolites; 10% as minor metabolites. Total renal clearance 180 mL/min, active tubular secretion accounts for 60% of renal elimination.
Renal excretion accounts for approximately 70% of elimination, with the remainder as unchanged drug in feces (20%) and biliary excretion (10%).
