SODIUM SULFACETAMIDE vs THIOSULFIL
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.
Thiosulfil (sulfamethizole) is a sulfonamide antibiotic that inhibits bacterial dihydropteroate synthase, blocking folic acid synthesis and thereby nucleic acid production.
1-2 drops of 10% or 30% solution into conjunctival sac every 2-3 hours during waking hours for 7-10 days.
500 mg orally twice daily for 10-14 days.

7-12 hours in normal renal function; prolonged to 20-50 hours in renal impairment.
Terminal elimination half-life is 2-4 hours in patients with normal renal function (creatinine clearance >80 mL/min); prolonged to 20-50 hours in severe renal impairment (CrCl <30 mL/min).
Renal: 85-100% unchanged drug via glomerular filtration and tubular secretion. Biliary/fecal: <5%.
Renal: 70-90% as unchanged drug via glomerular filtration and tubular secretion. Biliary/fecal: <5%.
