    Product Description

    Piperacillin is a broad-spectrum β-lactam antibiotic of the penicillin class.1,2 It is active against Gram-negative and Gram-positive bacteria, including Enterococcus species, E. coli, and P. mirabilis (MIC50s = 0.5-2 µg/ml) as well as gentamicin-susceptible and -resistant strains of P. aeruginosa (MIC50s = 8 and 125 µg/ml, respectively).2 In a mouse model of systemic infection, piperacillin is active against P. aeruginosa 46220 when used alone or in combination with tazobactam (Item No. 25679; ED50s = 1.58 and 1.34 mg/animal, respectively).3 In the same model, it is less active against P. aeruginosa 46220 DR-2, which contains constitutively active β-lactamase, when used alone than when used in combination with tazobactam (ED50s = >20 and 4.39 mg/animal, respectively). Formulations containing piperacillin in combination with tazobactam have been used in the treatment of moderate-to-severe bacterial infections.

    WARNING This product is not for human or veterinary use.
