AMPICILLIN SODIUM vs PENICILLIN
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.
Inhibits bacterial cell wall synthesis by binding to penicillin-binding proteins (PBPs), inhibiting transpeptidation and autolysin activation, leading to cell lysis.
1-2 g IV/IM every 4-6 hours for serious infections; maximum 12 g/day.
Penicillin G: 2-4 million units IV every 4-6 hours; Penicillin V: 250-500 mg orally every 6 hours for mild to moderate infections.

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.
Clinical Note
moderateBenzylpenicillin + Teriflunomide
"The serum concentration of Teriflunomide can be increased when it is combined with Benzylpenicillin."
Clinical Note
moderateBenzylpenicillin + Acemetacin
"Benzylpenicillin may decrease the excretion rate of Acemetacin which could result in a higher serum level."
Clinical Note
moderateProcaine benzylpenicillin + Acemetacin
"Procaine benzylpenicillin may decrease the excretion rate of Acemetacin which could result in a higher serum level."
Clinical Note
moderate0.5-1.0 hours in normal renal function; prolonged to 7-10 hours in anuria. Dose adjustment required in renal impairment.
Approximately 90% renal excretion via tubular secretion and glomerular filtration; small biliary excretion (<10%); fecal elimination negligible.
Primarily renal (60-80% unchanged via glomerular filtration and tubular secretion); biliary/fecal excretion accounts for 10-20%.
