LANABIOTIC vs ZOSYN
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
LANABIOTIC is a lantibiotic that inhibits bacterial cell wall synthesis by binding to lipid II, a key precursor in peptidoglycan biosynthesis, thereby disrupting cell wall integrity and causing cell death.
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.
500 mg orally every 12 hours for 7-14 days.
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.

Terminal elimination half-life is 6-8 hours in patients with normal renal function; extends to 20-40 hours in severe renal impairment (CrCl <30 mL/min).
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 excretion of unchanged drug accounts for 60-80% of elimination; biliary/fecal excretion accounts for 15-30%.
Primarily renal; piperacillin 68% unchanged, tazobactam 80% unchanged; biliary/fecal excretion <10%
