Shelf lives of aseptically prepared medicines-Stability of piperacillin/tazobactam in PVC and non-PVC bags

Shelf lives were calculated using the maximum rate method. Tazocin™ was found to be stable in 0.9% (w/v) sodium chloride in PVC bags for up to 5 days at 7 °C and 4 days at both 25 °C and RTL. In non-PVC bags, it was stable for 17, 4 and 3 days, respectively. It was stable in the buffered sodium chloride formulation in non-PVC bags for up to 58 days at 7 °C, 10 days at 25 °C and 7 days at RTL.
