Isoflurane

Contributor(s): Mark Senior, Vetstream Ltd

Introduction

Name

  • Isoflurane.
It was recently announced that the third-party manufacturer of isoflurane had to cease production with immediate effect, resulting in a shortfall of the anesthetic. Stocks of alternative products are believed to be limited, with the potential for supply to be restricted. However, it has now been announced that BEVA, BSAVA and the AVA have successfully engaged with the VMD to facilitate a practical solution to the isoflurane supply problem.
