SODIUM SULFACETAMIDE vs SULSTER
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.
Sulster is a sulfonamide antibiotic that inhibits bacterial dihydropteroate synthase, blocking folate synthesis and thus 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.

7-12 hours in normal renal function; prolonged to 20-50 hours in renal impairment.
Terminal half-life 3.5-4.5 hours in normal renal function; prolonged to 10-15 hours with creatinine clearance <30 mL/min.
Renal: 85-100% unchanged drug via glomerular filtration and tubular secretion. Biliary/fecal: <5%.
Primarily renal (60-70% unchanged), with 20-30% as glucuronide conjugate; biliary/fecal <10%.
