New drug stability data for 24hr administration of piperacillin 

Accufuser Elastomeric: New drug stability data now available for 24hr administration of piperacillin 

In order to assign a shelf life to a prepared product in an elastomeric device, comprehensive stability tests must be completed.

NHS standards, known as the Yellow Covered Document (YCD) stipulate the minimum testing requirements before an expiry date can be given.

These include:

  • Testing temperature requirements: 32°C +/- 1°C for in-use ‘near to body studies’ (for elastomeric devices and similarly insulated devices)
  • A concentration of 95-105% of active pharmaceutical ingredient must be present at the end of infusion
  • All samples tested in duplication
  • Low and high ‘clinically significant’ concentrations
  • Complete physical stability testing e.g. colour, clarity, precipitation, pH
  • Three samples at each time point
  • At least four time points plus time zero
  • Use of a stability indicating assay e.g. HPLC.


We can now confirm that the YCD drug stability data specifically for piperacillin and tazobactam is now available.
