DEXASPORIN vs PRED-G
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Dexasporin is a synthetic corticosteroid with potent anti-inflammatory and immunosuppressive properties. It binds to the glucocorticoid receptor, leading to modulation of gene expression and inhibition of pro-inflammatory mediators such as prostaglandins and leukotrienes.
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.
1 to 2 mg/kg intramuscular or intravenous 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.

3-4 hours (prolonged to 10-15 hours in renal impairment; monitor CrCl <30 mL/min)
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 (80-90% unchanged), biliary/fecal (10-20%)
Renal excretion accounts for approximately 70% of elimination, with the remainder as unchanged drug in feces (20%) and biliary excretion (10%).
