Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Sulfacetamide is a sulfonamide antibiotic that inhibits bacterial dihydropteroate synthase, blocking the conversion of p-aminobenzoic acid (PABA) to dihydrofolate, thereby inhibiting bacterial folic acid synthesis and exerting bacteriostatic activity.
Chloramphenicol inhibits bacterial protein synthesis by binding to the 50S ribosomal subunit, preventing peptide bond formation.
Instill 1-2 drops into the conjunctival sac every 3-4 hours, initially up to every 2 hours for severe infections.
Chloramphenicol 0.5% ophthalmic solution: Instill 1-2 drops into the affected eye(s) every 3-4 hours for 7-10 days. For severe infections, every 2 hours initially. Ointment: Apply a small amount (about 0.5 cm) into the conjunctival sac every 3-4 hours.

Terminal elimination half-life is 60-90 minutes in patients with normal renal function; prolonged in renal impairment.
5-6 hours in normal renal function; prolonged up to 24-48 hours in severe renal impairment
Renal excretion of unchanged drug accounts for approximately 50-70% of the dose; biliary/fecal excretion is minimal (<10%).
Renal: 70-80% unchanged; biliary/fecal: 20-30%
