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.
Oritavancin is a lipoglycopeptide antibiotic that inhibits bacterial cell wall synthesis by binding to the D-alanyl-D-alanine terminus of the peptidoglycan precursor, disrupting transglycosylation and transpeptidation. It also disrupts bacterial membrane integrity and causes depolarization, leading to cell death.
Apply 0.5-inch ribbon into the conjunctival sac(s) 1-2 times daily, or more frequently as directed.

Terminal half-life approximately 4-6 hours; clinical context: dosing every 4-6 hours for ocular infections
Terminal elimination half-life is approximately 15.1 hours in healthy adults; in patients with renal impairment, half-life is prolonged (up to 28 hours in severe renal impairment).
Renal (70-80% as unchanged drug and metabolites), biliary/fecal (20-30%)
Primarily renal excretion as unchanged drug (approximately 33% of administered dose) and via biliary/fecal elimination (~50% recovered in feces as parent drug and metabolites).
