PharmPK Discussion - Isoniazid Stability in Plasma

• On 13 Nov 1995 at 11:51:24, Colin Pillai (cpillai.-at-.pixie.udw.ac.za) sent the message
  

  
  We are presently developing an HPLC assay for isoniazid and AcINH (in
  plasma) in our  laboratory but are having difficulty with inter-day
  reproducibility of results.
  
  Other authors have reported a problem with the stability of INH and its
  acetyl derivative and we therefore store all samples in  cryotubes in a
  cooler box with dry-ice  (solid carbon dioxide).  We do
  not have a -70 freezer.
  
  Is there anyone out there that is available to discuss this with us and
  make suggestions as to what we are doing wrong?
  
  Thanks
