TICAR vs ZOSYN IN PLASTIC CONTAINER
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Ticarcillin is a beta-lactam antibiotic that inhibits bacterial cell wall synthesis by binding to penicillin-binding proteins (PBPs), leading to cell lysis and death. It is a time-dependent bactericidal agent.
Piperacillin, a ureidopenicillin, inhibits bacterial cell wall synthesis by binding to penicillin-binding proteins (PBPs), inhibiting transpeptidation and autolysin inhibitors. Tazobactam, a beta-lactamase inhibitor, irreversibly inactivates beta-lactamases, preventing hydrolysis of piperacillin.
3 g IV every 4 hours for pseudomonal infections; 3 g IV every 6 hours for less severe infections.
3.375 g (piperacillin 3 g + tazobactam 0.375 g) intravenously every 6 hours over 30 minutes. For nosocomial pneumonia, 4.5 g every 6 hours.

Clinical Note
moderateTicarcillin + Probenecid
"The serum concentration of Probenecid can be increased when it is combined with Ticarcillin."
Clinical Note
moderateTicarcillin + Mycophenolic acid
"The serum concentration of the active metabolites of Mycophenolic acid can be reduced when Mycophenolic acid is used in combination with Ticarcillin resulting in a loss in efficacy."
Clinical Note
moderateTicarcillin + Plicamycin
"The serum concentration of Plicamycin can be decreased when it is combined with Ticarcillin."
Clinical Note
moderateTerminal elimination half-life is approximately 1.2 hours in adults with normal renal function. In renal impairment, half-life may extend to 15-20 hours; dose adjustment required for CrCl <60 mL/min.
Piperacillin: 0.7-1.2 hours (normal renal function). Tazobactam: 0.7-0.9 hours. Clinically, half-life extends to 2-6 hours in renal impairment (CrCl <20 mL/min); requires dose adjustment.
Ticarcillin is primarily excreted unchanged in urine via glomerular filtration and tubular secretion, accounting for 90-95% of the dose. Biliary/fecal excretion is minimal (<5%).
Piperacillin: ~68% renal (glomerular filtration and tubular secretion), 9-17% biliary. Tazobactam: ~80% renal (unchanged and inactive metabolite). Mean cumulative urinary recovery: piperacillin 68%, tazobactam 80%; fecal recovery: piperacillin ~11%, tazobactam <1%.
