The physico-chemical stability of an injectable preparation (IV) is conditioned by different parameters. A collaboration between the pharmacy, the chemistry laboratory and the statisticians of the scientific support unit was established in 1996, in order to carry out long-term chemical stability studies of commonly used IVs and to be able to take charge of their preparation in pharmacy. In 24 years of activity, the Drug Stability Research Group (DSRG) tested 39 IV at different concentration and temperature of storage. The DSRG has organized an annual symposium since 2015. The theme of the 2019 edition was devoted to the robotization of injectable reconstitution operations, focused on their impact on the workplace and the existing equipment.
