Tazobactam (TAZ) is a newly developed beta-lactamase inhibitor. Tazobactam/Piperacillin (TAZ/PIPC) is a formulation consisting of TAZ and PIPC in a ratio of 1:4. Singe-dose toxicity studies in TAZ/PIPC and TAZ were carried out using mice and rats of both sexes and male dogs. The results were as follows. 1. A common clinical sign in mice and rats administered TAZ/PIPC or TAZ by all routes was soft stool. Other signs in mice and rats included a decrease in spontaneous motor activity and/or a decreased respiratory rate for the intraperitoneal (i.p.), subcutaneous (s.c.) or intravenous (i.v.) route. The animals administered by the i.v. route showed tremor for mice and clonic convulsion for rats before death. Hyperemia, hemorrhage or edema of the lung, and hemorrhage of the digestive tract were observed in these animals at necropsy. An enlargement of the spleen was seen in some of the surviving animals treated with TAZ/PIPC. 2. In dogs, TAZ/PIPC caused vomiting, and TAZ caused vomiting, respiratory abnormality, soft stool and diarrhea by the intravenous (i.v.) administration. 3. TAZ/PIPC or TAZ caused clinical signs such as the loss of hair at the injection site for the s.c. route, and necrosis of the tail for the i.v. route in mice and rats, also caused limping of the injected anterior limb in dogs. Necrosis and hemorrhage at the injection site, and peritonitis by the i.p. injection were observed at necropsy. These findings were due to the irritation of TAZ/PIPC or TAZ.(ABSTRACT TRUNCATED AT 250 WORDS)

Despite popular use of piperacillin, the dire neurotoxicity associated with piperacillin still goes unrecognized, leading to a delay in appropriate management. We report a 57-year-old woman with end-stage renal disease receiving continuous ambulatory peritoneal dialysis (CAPD), who developed slurred speech, tremor, bizarre behavior, progressive mental confusion, and 2 episodes of generalized tonic-clonic seizure (GTCS) after 5 doses of piperacillin/tazobactam (2 g/250 mg) were given for bronchiectasis with secondary infection. The laboratory data revealed normal plasma electrolyte and ammonia levels but leukocytosis. Neurologic examinations showed dysarthria and bilateral Babinski sign. Computed tomography of brain and electroencephalogram were unremarkable. Despite the use of antiepileptic agents, another GTCS episode recurred after the sixth dose of piperacillin/tazobactam. Brain magnetic resonance imaging did not demonstrate acute infarction and organic brain lesions. Initiation of high-flux hemodialysis rapidly reversed the neurologic symptoms within 4 hours. Piperacillin-induced encephalopathy should be considered in any uremic patients with unexplained neurological manifestations. CAPD is inefficient in removing piperacillin, whereas hemodialysis can rapidly terminate the piperacillin-induced encephalopathy.
