OPHTHOCHLOR vs OPTOMYCIN
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Chloramphenicol inhibits bacterial protein synthesis by binding to the 50S ribosomal subunit, preventing peptide bond formation.
Optomycin is a semi-synthetic glycopeptide antibiotic that inhibits bacterial cell wall synthesis by binding to the D-alanyl-D-alanine terminus of the peptidoglycan precursor, preventing transpeptidation and cross-linking.
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.
1.5 mg/kg IV every 8 hours; alternatively, 5-7 mg/kg IV daily.
