Summary for Patent: 6,207,661

Title: Premixed formulation of piperacillin sodium and tazobactam sodium injection
Abstract:The present invention provides a premixed form of a buffered piperacillin product having a near neutral pH and capable of a shelf life of at least nine months, with freezer storage (-20.degree. C. or lower), or a refrigerated shelf life of up to 14 days at about 5.degree. C. The piperacillin may additionally contain a tazobactam component to inactivate beta-lactamases that commonly cause resistance to penicillins, allowing the piperacillin component to destroy susceptible bacteria. With the addition of dextrose, the premixed composition is physiologically isosmotic.
