SODIUM SULFACETAMIDE vs TERFONYL
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Sulfacetamide is a sulfonamide antibiotic that inhibits bacterial dihydropteroate synthase, thereby blocking the synthesis of folic acid and ultimately nucleic acid synthesis, leading to bacteriostatic activity.
TERFONYL is a sulfonamide antibiotic that inhibits bacterial dihydropteroate synthase, thereby blocking folate synthesis and bacterial DNA replication.
1-2 drops of 10% or 30% solution into conjunctival sac every 2-3 hours during waking hours for 7-10 days.
2 g intravenously every 12 hours over 24 hours for susceptible infections.

7-12 hours in normal renal function; prolonged to 20-50 hours in renal impairment.
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: 85-100% unchanged drug via glomerular filtration and tubular secretion. Biliary/fecal: <5%.
Renal excretion accounts for 70-90% of elimination as unchanged drug via glomerular filtration and tubular secretion; biliary/fecal excretion constitutes 10-30%.
