Laboratory and clinical studies of piperacillin



Laboratory and clinical studies of piperacillin



Chinese Medical Journal 96(12): 885-892



Antibacterial activity, clinical pharmacology and clinical trials of piperacillin are reported. Bacterial susceptibility testing of 387 clinical isolates revealed that piperacillin is active against various gram-positive and gram-negative organisms, with especially marked activity against gram-negative organisms; inhibition rates against Pseudomonas aeruginosa and Escherichia coli were 90 and 79%, respectively. Peak serum levels after i.m. and i.v. injections and i.v. drip of 1 gm piperacillin in normal volunteers were 25, 142.1 and 58 .mu.g/ml, respectively. Pharmacokinetic parameters were calculated, based upon the specific therapeutic regimens used in treating various infections. Piperacillin was used in 148 infections including peritonitis, lung infections, septicemias, etc.; the total effective rate was 77.7% and the cure rate 55.4%. Adverse reactions were rare; no renal, hepatic or hemopoietic toxicity was noted.
