Stability Of Mycophenolate Mofetil In Polypropylene 5% Dextrose Infusion Bags And Chemical Compatibility Associated With The Use Of The Equashield (R) Closed-System Transfer Device

Stability studies are necessary in healthcare settings as they facilitate fast, cost-effective and efficient work related to batch manufacturing and availability of supplies. We studied the stability of 1-10 mg/mL mycophenolate mofetil (MMF) in polypropylene 5% dextrose infusion bags prepared from Cellcept (R) and with a generic brand name (Micofenolato de Mofetilo Accord) at different storage temperatures. To ensure chemical compatibility during preparation, we also tested MMF sorption to the Equashield (R) closed-system drug transfer device used in this step. For this, a validated stability-indicating high-performance liquid chromatography method was developed for the quantification and identification of MMF in the infusion bags. The analytical selectivity of the assay was determined by subjecting an MMF sample to extreme values of pH, oxidative stress and heat conditions to force degradation. Protected from light, 1-10 mg/mL MMF in infusion polypropylene bags prepared from reconstituted Cellcept (R) 500 mg or Accord 500 mg in 5% dextrose was stable for at least 35 days when stored at 2-8 degrees C or between -15 and -25 degrees C, and for 14 days when stored at 25 degrees C. MMF loss owing to chemical sorption to the Equashield (R) closed-system drug transfer device set was negligible.
