Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Competitively inhibits dihydropteroate synthase, blocking folic acid synthesis in susceptible bacteria.
Bactericidal; inhibits cell wall synthesis by binding to penicillin-binding proteins (PBPs) and disrupting peptidoglycan cross-linking.
1-2 drops of 10-30% solution into the conjunctival sac every 2-3 hours initially, tapering as infection resolves. Ointment: 0.5-inch ribbon into conjunctival sac every 3-4 hours and at bedtime.
500 mg orally 4 times daily for 10-14 days (or 1 g orally 4 times daily for severe infections).

7-12.8 hours (prolonged in renal impairment; requires dosing adjustment in CrCl <50 mL/min).
8 hours (terminal) — extends in renal impairment (up to 24 hours in CrCl <30 mL/min); requires dose adjustment
Renal: 85-95% unchanged via glomerular filtration and tubular secretion. Biliary/fecal: <5%.
Renal: 70% (unchanged); biliary/fecal: 20%; minor hepatic metabolism (<10%)
