CHLOROPTIC S.O.P. vs TRIMETHOPRIM
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 (DHFR), preventing the reduction of dihydrofolate to tetrahydrofolate, thereby inhibiting thymidine synthesis and bacterial DNA replication. It has bacteriostatic activity against susceptible organisms.
Apply 0.5-inch ribbon into the conjunctival sac(s) 1-2 times daily, or more frequently as directed.
Adult: 100 mg orally twice daily or 200 mg once daily for uncomplicated UTI; for severe infections, up to 20 mg/kg/day in divided doses. IV: 10-20 mg/kg/day divided every 6-12 hours.

Clinical Note
moderateTrimethoprim + Fluconazole
Terminal half-life approximately 4-6 hours; clinical context: dosing every 4-6 hours for ocular infections
Terminal elimination half-life is 8-12 hours in adults with normal renal function; prolonged to 20-40 hours in severe renal impairment (CrCl <15 mL/min).
Renal (70-80% as unchanged drug and metabolites), biliary/fecal (20-30%)
Renal excretion: approximately 50-60% of the dose is excreted unchanged in urine via glomerular filtration and tubular secretion; about 10-20% as metabolites (conjugated and oxidized forms); biliary/fecal excretion accounts for less than 10%.
