Ampicillin vs PENTIDS '200'
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.
Penicillin G is a beta-lactam antibiotic that inhibits bacterial cell wall synthesis by binding to penicillin-binding proteins (PBPs), thereby inhibiting transpeptidation and activating autolytic enzymes.
250-500 mg orally every 6 hours; 1-2 g IV/IM every 4-6 hours.
Penicillin G benzathine: 1.2 million units intramuscularly as a single dose.

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
moderateAmpicillin + Acemetacin
"Ampicillin may decrease the excretion rate of Acemetacin which could result in a higher serum level."
Clinical Note
moderateAmpicillin + Probenecid
"The serum concentration of Probenecid can be increased when it is combined with Ampicillin."
Clinical Note
moderateBacampicillin + Probenecid
"The serum concentration of Probenecid can be increased when it is combined with Bacampicillin."
Clinical Note
moderatePivampicillin + Probenecid
0.5-1 hour; prolonged in renal impairment; anuric patients up to 10 hours
Renal: 90% unchanged via glomerular filtration and tubular secretion; biliary: 10% (small amount).
Renal: 60-90% unchanged; biliary/fecal: 10-40%
