Flupirtine maleate (Katadolon maleate) is the salt form of Flupirtine, a centrally acting, non-opioid analgesic. It functions as an NMDA receptor antagonist and a selective neuronal potassium channel opener. This compound is utilized in research areas such as neuropharmacology and pain mechanisms, applicable in both in vitro receptor studies and in vivo animal models of analgesia.
