BESIVANCE vs OPHTHOCHLOR
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
BESIVANCE is a fluoroquinolone antibiotic that inhibits bacterial DNA gyrase (topoisomerase II) and topoisomerase IV, thereby blocking DNA replication and leading to bacterial cell death.
Chloramphenicol inhibits bacterial protein synthesis by binding to the 50S ribosomal subunit, preventing peptide bond formation.
One drop instilled into the affected eye(s) three times daily for 7 days.
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 half-life of approximately 1.5-2 hours in adults; prolongation in renal impairment.
5-6 hours in normal renal function; prolonged up to 24-48 hours in severe renal impairment
Primarily excreted unchanged in urine (approximately 50-60%) and feces (approximately 20-30%); biliary excretion contributes to fecal elimination.
Renal: 70-80% unchanged; biliary/fecal: 20-30%
