Description

technical field [0001] The invention belongs to the field of pharmaceutical preparations. Background technique [0002] Lacosamide is a novel NMDA receptor glycine site-binding antagonist, which belongs to a new class of functional amino acids and is an anticonvulsant drug with a new dual mechanism of action. Lacosamide is used in combination with first- and second-generation antiepileptic drugs to improve epilepsy control. It selectively promotes the slow inactivation of sodium channels and regulates collapse response mediator protein-2 (CRMP-2), which may delay or even block epileptic seizures and alleviate diabetic neuropathic pain. [0003] Epilepsy is a common neurological disorder affecting approximately 500,000 people worldwide. Central nervous system (CNS) drugs have always been a relatively active area of ​​development. Among them, the average annual growth rate of antiepileptic drugs in the international market is about 10%, ranking third in the growth rate of ce...
