TIMENTIN IN PLASTIC CONTAINER vs ZOSYN
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Timentin is a combination of ticarcillin, a penicillin-class beta-lactam antibiotic, and clavulanate, a beta-lactamase inhibitor. Ticarcillin inhibits bacterial cell wall synthesis by binding to penicillin-binding proteins (PBPs), while clavulanate irreversibly inhibits beta-lactamases, preventing degradation of ticarcillin.
Piperacillin, a semisynthetic penicillin, inhibits bacterial cell wall synthesis by binding to penicillin-binding proteins (PBPs). Tazobactam, a beta-lactamase inhibitor, inactivates beta-lactamases, preventing piperacillin degradation.
3.1 g (ticarcillin 3 g + clavulanate 0.1 g) IV every 4 to 6 hours; maximum 18 g per day.
3.375 g (piperacillin 3 g / tazobactam 0.375 g) intravenously every 6 hours over 30 minutes; for nosocomial pneumonia, 4.5 g intravenously every 6 hours.

Ticarcillin: ~1.2 hours; Clavulanate: ~1.0 hours. Prolonged in renal impairment (ticarcillin up to 15 hours in ESRD).
Piperacillin ~0.7-1.2 h; tazobactam ~0.7-1.0 h; extended in renal impairment (piperacillin up to 3.3 h, tazobactam up to 4.7 h in CrCl <20 mL/min)
Renal: ~70-80% of ticarcillin and ~60-70% of clavulanate excreted unchanged in urine within 6 hours. Biliary/fecal: Minor (<5%).
Primarily renal; piperacillin 68% unchanged, tazobactam 80% unchanged; biliary/fecal excretion <10%
