The Stability of Remifentanil Hydrochloride and Propofol Mixtures in Polypropylene Syringes and Polyvinylchloride Bags at 22°o–24°C

IMPLICATIONS: Remifentanil and propofol mixtures may be prepared extemporaneously. This study demonstrated that such mixtures are stable for 0 to 36 h, depending on relative concentrations of the drugs and the storage container used. The most stable mixtures were stored in syringes and used large concentrations of the two drugs.
