Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Chloroptic (chloramphenicol) inhibits bacterial protein synthesis by binding to the 50S ribosomal subunit, preventing peptide bond formation.
Fosfomycin inhibits bacterial cell wall synthesis by inactivating the enzyme UDP-N-acetylglucosamine enolpyruvyl transferase (MurA), which catalyzes the first step of peptidoglycan biosynthesis.
1 drop (0.5% solution) into the affected eye(s) every 4-6 hours.
3 g orally once as a single dose for uncomplicated urinary tract infection.

Terminal elimination half-life is approximately 2-4 hours in patients with normal renal function, necessitating frequent dosing (every 4-6 hours) to maintain therapeutic levels.
Terminal elimination half-life is 5.7 hours (range 3-8 hours) in patients with normal renal function; approximately 50 hours in end-stage renal disease (CrCl <10 mL/min).
Primarily renal elimination (70-80% as unchanged drug). Minor biliary/fecal excretion (<10%).
Primarily excreted unchanged in urine via glomerular filtration (approximately 90% of absorbed dose within 24-48 hours); small amount (approximately 10%) excreted in feces via biliary elimination.
