AMPICILLIN SODIUM vs PROBAMPACIN
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Ampicillin is a beta-lactam antibiotic that inhibits bacterial cell wall synthesis by binding to penicillin-binding proteins (PBPs), leading to cell lysis and death.
PROBAMPACIN is a synthetic aminoglycoside antibiotic that inhibits bacterial protein synthesis by binding to the 30S ribosomal subunit, causing misreading of mRNA and preventing translocation of peptidyl-tRNA from the A-site to the P-site.
1-2 g IV/IM every 4-6 hours for serious infections; maximum 12 g/day.
100 mg IV every 12 hours over 30 minutes.

Terminal elimination half-life ~1 hour in healthy adults; prolonged to 2–5 hours in renal impairment (CrCl <10 mL/min) and up to 7–20 hours in anuria; neonatal half-life 2–4 hours.
4.5 hours (prolonged to 12-18 hours in severe renal impairment)
Approximately 90% renal excretion via tubular secretion and glomerular filtration; small biliary excretion (<10%); fecal elimination negligible.
Renal: 70% unchanged; biliary/fecal: 20% as metabolites; 10% other
