Piperacillin with tazobactam is administered through an intravenous (IV) method, where it is infused into the bloodstream over a period of 30 minutes to 4 hours so that the medication is delivered slowly and steadily.
occasionally penicillins including penicillin, ampicillin and ampicillin-sulbactam, amoxicillin and amoxicillin-clavulnate, and piperacillin-tazobactam (not all vancomycin-resistant Enterococcus isolates are resistant to penicillin and ampicillin) occasionally doxycycline and minocycline
Piperacillin is a broad-spectrum β-lactam antibiotic of the ureidopenicillin class. [1] The chemical structure of piperacillin and other ureidopenicillins incorporates a polar side chain that enhances penetration into Gram-negative bacteria and reduces susceptibility to cleavage by Gram-negative beta lactamase enzymes.
Tazobactam is a pharmaceutical drug that inhibits the action of bacterial β-lactamases, especially those belonging to the SHV-1 and TEM groups. It is commonly used as its sodium salt , tazobactam sodium.
The addition of tazobactam to piperacillin has enhanced its stability against a wide range of β-lactamase enzymes including some Extended-Spectrum β-lactamases. [20] Other β-lactamase inhibitors such as boronic acids are being studied in which they irreversibly bind to the active site of β-lactamases. This is a benefit over clavulanic acid ...
A 2015 meta analysis concluded that the anti-pseudomonal penicillin-beta lactamase inhibitor combination piperacillin-tazobactam gives results equivalent to treatment with a carbapenem in patients with sepsis. [11]
