Ampicillin vs PENICILLIN
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Ampicillin is a penicillin antibiotic that inhibits bacterial cell wall synthesis by binding to penicillin-binding proteins (PBPs), inhibiting transpeptidase activity, and disrupting peptidoglycan cross-linking.
Inhibits bacterial cell wall synthesis by binding to penicillin-binding proteins (PBPs), inhibiting transpeptidation and autolysin activation, leading to cell lysis.
250-500 mg orally every 6 hours; 1-2 g IV/IM every 4-6 hours.
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: 1-1.8 hours in adults with normal renal function; prolonged to 7-20 hours in end-stage renal disease (CrCl <10 mL/min).
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
moderateAmpicillin + Acemetacin
"Ampicillin 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.
Renal: 90% unchanged via glomerular filtration and tubular secretion; biliary: 10% (small amount).
Primarily renal (60-80% unchanged via glomerular filtration and tubular secretion); biliary/fecal excretion accounts for 10-20%.
