Stability of Fentanyl Citrate in Polyolefin Bags.
Fentanyl is used to manage pain because it is a potent lipophilic opiate agonist. The stability of fentanyl in polyolefin bags when diluted to either 10 µg/mL or 50 µg/mL with sodium chloride 0.9% has not been studied. The chemical stability of fentanyl 50 µg/mL packaged in polyvinyl chloride bags has been studied, however, the stability in polyolefin bags is lacking. Polyolefin bags were aseptically filled with either 10-µg/mL or 50-µg/mL fentanyl solution. Containers were then stored at either 5°C and protected from light or 22°C and exposed to light for 93 days. Fentanyl peaks were monitored using a stability-indicatin high-performance liquid chromatographic method. Changes to color, clarity, and pH were also monitored. There were no signs of chemical degradation of fentanyl packaged in polyolefin bags at either 5°C or 22°C after storage for 93 days. Over the course of the study, all solutions remained colorless and clear. The pH showed a slight decrease during the 93 days of storage. The stability of both undiluted (50-µg/mL) and diluted (10-µg/mL) fentanyl solutions when packaged in polyolefin bags was 93 days when stored at either 5°C or 22°C.
