Ampicillin vs AZLIN
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.
Azlin is a penicillin antibiotic that inhibits bacterial cell wall synthesis by binding to penicillin-binding proteins (PBPs), leading to cell lysis.
250-500 mg orally every 6 hours; 1-2 g IV/IM every 4-6 hours.
1-2 grams intravenously every 4-6 hours; total daily dose up to 12 grams for serious 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
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
Terminal elimination half-life is approximately 1.0–1.5 hours in adults with normal renal function; prolonged to 3–5 hours in moderate renal impairment (CrCl 10–50 mL/min) and up to 10 hours in severe renal impairment (CrCl <10 mL/min).
Renal: 90% unchanged via glomerular filtration and tubular secretion; biliary: 10% (small amount).
Renal excretion of unchanged drug (approximately 60-70% via glomerular filtration and tubular secretion); biliary/fecal excretion accounts for <10%.
