CHLORAMPHENICOL SODIUM SUCCINATE vs PROLOPRIM
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Reversibly binds to the 50S ribosomal subunit, inhibiting peptidyl transferase activity and blocking protein synthesis in bacteria.
Inhibits bacterial dihydrofolate reductase (DHFR), blocking the conversion of dihydrofolic acid to tetrahydrofolic acid, thereby inhibiting bacterial DNA, RNA, and protein synthesis.
Intravenous, 50 mg/kg/day divided every 6 hours; maximum 4 g/day.
100 mg orally twice daily or 200 mg orally once daily.

Terminal elimination half-life is approximately 1.5-3.5 hours in adults with normal renal and hepatic function. In neonates (first 2 weeks of life), half-life is prolonged to 10-24 hours due to immature hepatic conjugation. In patients with severe hepatic impairment, half-life may exceed 12 hours, necessitating dose adjustment.
Terminal elimination half-life is 8-10 hours in normal renal function; prolonged (>20 hours) in significant renal impairment.
Approximately 80-90% of the dose is excreted renally as unchanged drug and as the inactive chloramphenicol base (formed by hydrolysis in the liver and kidneys). Biliary excretion accounts for about 5-10%, with some enterohepatic circulation. Fecal excretion is negligible (<2%).
Primarily renal (80-90% as unchanged drug); less than 5% as metabolites; fecal excretion negligible.
