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.
Fidaxomicin is a macrocyclic antibiotic that inhibits bacterial RNA polymerase, leading to RNA synthesis inhibition and cell death. It is bactericidal against Clostridioides difficile and has minimal systemic absorption.
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
11.7 hours (terminal half-life in healthy subjects); supports twice-daily dosing.
Renal (70-80% as unchanged drug and metabolites), biliary/fecal (20-30%)
Fecal (primarily as unchanged drug, ~44% of dose); renal (~1.6% unchanged, <1% as metabolites); biliary (minor).
