It is combined with [Piperacillin] and [Ceftolozane] for the treatment of a variety of bacterial infections.  Piperacillin-tazobactam was initially approved by the FDA in 1994, and ceftolozane-tazobactam was approved by the FDA in 2014, providing wider antibacterial coverage for gram-negative infections. In June 2019, ceftolozane-tazobactam was approved by the FDA for treating hospital-acquired bacterial pneumonia and ventilator-associated bacterial pneumonia, which are significant causes of morbidity and mortality in hospitalized patients."}]
