AMOXICILLIN PEDIATRIC vs PIPERACILLIN
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Amoxicillin is a semisynthetic penicillin antibiotic that inhibits bacterial cell wall synthesis by binding to penicillin-binding proteins (PBPs). It blocks the transpeptidation step in peptidoglycan cross-linking, leading to cell lysis and death.
Inhibits bacterial cell wall synthesis by binding to penicillin-binding proteins (PBPs), inhibiting transpeptidation, and activating autolytic enzymes.
250-500 mg orally every 8 hours or 500-875 mg orally every 12 hours for adults.
3.375 g IV every 6 hours (piperacillin-tazobactam); for piperacillin alone, 3 g IV every 6 hours.

Terminal elimination half-life: 1-1.5 hours in children with normal renal function; prolonged to 7-21 hours in anuria.
Clinical Note
moderatePiperacillin + Probenecid
"The serum concentration of Probenecid can be increased when it is combined with Piperacillin."
Clinical Note
moderatePiperacillin + Mycophenolic acid
"The serum concentration of the active metabolites of Mycophenolic acid can be reduced when Mycophenolic acid is used in combination with Piperacillin resulting in a loss in efficacy."
Clinical Note
moderatePiperacillin + Plicamycin
"The serum concentration of Plicamycin can be decreased when it is combined with Piperacillin."
Clinical Note
moderate0.6-1.2 hours in adults with normal renal function; prolonged to 2-6 hours in renal impairment (CrCl <20 mL/min); requires dose adjustment in renal failure
Renal: 60-80% unchanged via glomerular filtration and tubular secretion; biliary: minor (<10%); fecal: <5%.
Renal: approximately 70-90% unchanged via glomerular filtration and tubular secretion; biliary: 10-20% excreted unchanged in bile; fecal: minor (<5%)
