CHLOROPTIC vs LANTRISUL
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Chloroptic (chloramphenicol) inhibits bacterial protein synthesis by binding to the 50S ribosomal subunit, preventing peptide bond formation.
Lantrisul (sulfadimethoxine) is a sulfonamide antibiotic that inhibits bacterial synthesis of dihydrofolic acid by competing with para-aminobenzoic acid (PABA) for the enzyme dihydropteroate synthase, thereby blocking folic acid synthesis and ultimately nucleic acid production in susceptible bacteria.
1 drop (0.5% solution) into the affected eye(s) every 4-6 hours.
Intravenous: 3 mg/kg every 8 hours for 14 days, then 5 mg/kg every 12 hours for 14 days; oral: 800 mg (10 mg/kg) twice daily after intravenous phase.

Terminal elimination half-life is approximately 2-4 hours in patients with normal renal function, necessitating frequent dosing (every 4-6 hours) to maintain therapeutic levels.
Terminal elimination half-life is 18 hours (range 16-20 h). This supports once-daily dosing; steady-state achieved after 3-4 days.
Primarily renal elimination (70-80% as unchanged drug). Minor biliary/fecal excretion (<10%).
Approximately 70% renal excretion as unchanged drug, 15% fecal elimination via biliary secretion, 10% metabolized to inactive glucuronide conjugate eliminated renally, 5% other minor pathways.
