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.
Trimethoprim inhibits bacterial dihydrofolate reductase, blocking the conversion of dihydrofolic acid to tetrahydrofolic acid, thereby inhibiting bacterial DNA synthesis.
Apply 0.5-inch ribbon into the conjunctival sac(s) 1-2 times daily, or more frequently as directed.
200 mg orally once daily, or 100 mg orally twice daily.

Terminal half-life approximately 4-6 hours; clinical context: dosing every 4-6 hours for ocular infections
Terminal elimination half-life is 8-10 hours in adults with normal renal function; prolonged to 20-30 hours in renal impairment (CrCl <30 mL/min), requiring dose adjustment.
Renal (70-80% as unchanged drug and metabolites), biliary/fecal (20-30%)
Renal excretion of unchanged drug accounts for approximately 60-80% of elimination, with an additional 10-20% as hepatic metabolites excreted in bile and feces.
