CHLOROMYCETIN vs TRIMETHOPRIM
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
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.
50-100 mg/kg/day IV divided every 6 hours; maximum 4 g/day. Topical: apply to affected area 2-4 times daily.
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 + Teriflunomide
"The metabolism of Teriflunomide can be decreased when combined with Trimethoprim."

Clinical Note
moderateTrimethoprim + Cyclosporine
"The metabolism of Cyclosporine can be decreased when combined with Trimethoprim."
Clinical Note
moderateTrimethoprim + Fluconazole
1.5-4 hours in adults; prolonged to 3-7 hours in neonates and 4-12 hours in hepatic impairment; clinical context: dose adjustment required in liver disease.
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: 5-10% unchanged; hepatic glucuronidation (90%) followed by renal elimination of metabolites; small biliary excretion (<5%) and fecal elimination.
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%.
