DYCILL vs PIPERACILLIN
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Penicillin G benzathine is a slow-release parenteral formulation of penicillin G that inhibits bacterial cell wall synthesis by binding to penicillin-binding proteins (PBPs), inhibiting transpeptidation, and activating autolytic enzymes.
Inhibits bacterial cell wall synthesis by binding to penicillin-binding proteins (PBPs), inhibiting transpeptidation, and activating autolytic enzymes.
250 mg orally every 6 hours or 500 mg orally every 12 hours.
3.375 g IV every 6 hours (piperacillin-tazobactam); for piperacillin alone, 3 g IV every 6 hours.

0.5-1 hour; prolonged in renal impairment (up to 20 hours in severe cases).
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: approx. 60-80% unchanged by glomerular filtration and tubular secretion. Biliary/fecal: minor (less than 10%).
Renal: approximately 70-90% unchanged via glomerular filtration and tubular secretion; biliary: 10-20% excreted unchanged in bile; fecal: minor (<5%)
