Flupirtine Maleate 400 mg (sustained release) is a centrally acting, non-opioid analgesic used for the management of acute and chronic pain, especially of musculoskeletal origin. It works by opening neuronal potassium channels and indirectly antagonizing NMDA receptors, thereby reducing pain perception and muscle tension. Unlike conventional NSAIDs, it does not cause significant gastric irritation and is beneficial in patients where NSAIDs are contraindicated. It also exhibits muscle relaxant properties, making it useful in conditions involving muscle stiffness and spasms. However, its use is generally restricted due to potential hepatotoxicity, and it is recommended for short-term therapy under medical supervision.
