SODIUM SULFACETAMIDE vs TRYSUL
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.
Trypanocidal agent; forms a complex with DNA and inhibits nucleic acid synthesis.
1-2 drops of 10% or 30% solution into conjunctival sac every 2-3 hours during waking hours for 7-10 days.
2 tablets (each containing sulfamethoxazole 400 mg and trimethoprim 80 mg) orally every 12 hours for 10-14 days.

7-12 hours in normal renal function; prolonged to 20-50 hours in renal impairment.
Terminal elimination half-life: 8-10 hours in adults with normal renal function; prolonged to 20-30 hours in severe renal impairment (CrCl <30 mL/min).
Renal: 85-100% unchanged drug via glomerular filtration and tubular secretion. Biliary/fecal: <5%.
Renal: approximately 70-80% as unchanged drug via glomerular filtration and tubular secretion; biliary/fecal: 15-20% as metabolites; small amount in feces.
