Biochem/physiol Actions

Flupirtine is commercially available as maleate salt. It exists in two polymorphs : flupirtine maleate A and B. Flupirtine is useful in treating muscular spasm, muscle tension and muscle stiffness. It is known to be effective in relieving back pain. Along with cytoprotection, flupirtine also offers protection against neurodegenerative disorders such as multiple sclerosis, amyotrophic lateral sclerosis, Alzheimer′s disease, Parkinson′s disease, Huntington′s chorea and AID (acquired immunodeficiency) associated encephalopathy. Flupirtine is found to be a potential drug for eye-related problems like maculopathy including diabetic retinopathy, retinitis pigmentosa and glaucoma. It is also proved to be helpful in preventing cardiac associated disorders such as myocardial ischemia and infarction, cerebral ischemia and infarction. Hepatitis is also prevented by the use of flupirtine.
Non-opioid analgesic; cytoprotective versus PrP fragment 106-126

We have previously shown that the nonopioid analgesic flupirtine possesses analgesic activity in the orofacial formalin test in vivo in the rat. However, this paradigm does not allow to distinguish between central and peripheral site of action of the drug.

Flupirtine was developed long before K(V)7 (KCNQ) channels were known. However, it was clear from the beginning that flupirtine is neither an opioid nor a nonsteroidal anti-inflammatory analgesic. Its unique muscle relaxing activity was discovered by serendipity. In the meantime
