Baxter's (BAX) Clinimix and Clinimix E with Higher Protein Injection received FDA approval, which will help clinicians to improve care for critically ill patients.
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.
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.

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.
Ceftolozane exerts bactericidal activities against susceptible gram-negative and gram-positive infections by inhibiting essential penicillin-binding proteins (PBPs), which are required for peptidoglycan cross-linking for bacterial cell wall synthesis, resulting in inhibition of cell wall synthesis and subsequent cell death.
Narrow-spectrum antibiotics have low propensity to induce bacterial resistance and are less likely to disrupt the microbiome (normal microflora). [3] On the other hand, indiscriminate use of broad-spectrum antibiotics may not only induce the development of bacterial resistance and promote the emergency of multidrug-resistant organisms, but also cause off-target effects due to dysbiosis.
