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.
