SULFACETAMIDE SODIUM AND PREDNISOLONE SODIUM PHOSPHATE vs TERFONYL
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Sulfacetamide sodium inhibits bacterial dihydropteroate synthase, blocking folate synthesis; prednisolone sodium phosphate suppresses inflammation by binding glucocorticoid receptors, inhibiting phospholipase A2 and pro-inflammatory cytokine production.
TERFONYL is a sulfonamide antibiotic that inhibits bacterial dihydropteroate synthase, thereby blocking folate synthesis and bacterial DNA replication.
1-2 drops into the conjunctival sac of the affected eye(s) every 2-4 hours during the day and at bedtime; frequency may be decreased as clinical signs improve.
2 g intravenously every 12 hours over 24 hours for susceptible infections.

Sulfacetamide: 6-8 hours (prolonged in renal impairment). Prednisolone: 2-4 hours (terminal half-life). Clinically, systemic effects may persist longer due to tissue distribution.
Terminal elimination half-life is 2.5-4 hours in adults with normal renal function; prolonged to 12-24 hours in severe renal impairment (CrCl < 30 mL/min).
Renal excretion of unchanged sulfacetamide (60-75%) and prednisolone metabolites (primarily conjugated); minimal biliary/fecal elimination (<10% for each).
Renal excretion accounts for 70-90% of elimination as unchanged drug via glomerular filtration and tubular secretion; biliary/fecal excretion constitutes 10-30%.
