Ampicillin vs SPECTROBID
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.
Spectrobird (bacampicillin) is a prodrug of ampicillin, a beta-lactam antibiotic that inhibits bacterial cell wall synthesis by binding to penicillin-binding proteins (PBPs), leading to cell lysis and death.
250-500 mg orally every 6 hours; 1-2 g IV/IM every 4-6 hours.
400 mg orally twice daily or 200 mg orally four times daily for 10-14 days. For acute exacerbations of chronic bronchitis: 400 mg orally twice daily for 10 days.

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: 1-1.8 hours in adults with normal renal function; prolonged to 7-20 hours in end-stage renal disease (CrCl <10 mL/min).
Terminal elimination half-life: 1.5-2 hours in normal renal function; prolonged to 6-10 hours in severe renal impairment (CrCl <10 mL/min).
Renal: 90% unchanged via glomerular filtration and tubular secretion; biliary: 10% (small amount).
Renal: ~75-85% unchanged drug; fecal/biliary: ~15-25% as metabolites and unchanged drug.
