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.

Annually, adverse drug reactions result in more than 2,000,000 hospitalizations and rank among the top 10 causes of death in the United States. Consequently, there is a need to continuously monitor and to improve the safety assessment of marketed drugs.

L-DOPA-induced dyskinesias (LID) represent a severe complication of long-time pharmacotherapy in Parkinson's disease that necessitates novel therapeutics. The acute and chronic effects of K(V)7.2-7.5 channel openers (retigabine, flupirtine) on the severity of LID and parkinsonian signs were examined in comparison

Expression and function of Kv7 (KCNQ) voltage-activated potassium channels in guinea pig and human airway smooth muscle cells (ASMCs) were investigated by quantitative reverse transcriptase polymerase chain reaction (qRT-PCR), patch-clamp electrophysiology, and precision-cut lung slices. qRT-PCR revealed expression of multiple

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
