Ro48-8684 is a water-soluble benzodiazepine derivative developed by Hoffman-LaRoche in the 1990s, which was designed along with Ro48-6791 as an improved replacement for midazolam, but ultimately proved to have little advantages over the parent drug and has not been introduced into clinical practice.
