Used primarily in the treatment of neurodegenerative disorders, particularly Huntington’s disease and spinocerebellar ataxia. It functions by modulating glutamate signaling in the brain, helping to reduce excitotoxicity, which is a key factor in neuronal damage. Clinical studies have shown it may improve motor control, coordination, and overall neurological function in patients with these conditions. It is also being investigated for potential use in other glutamate-related disorders such as obsessive-compulsive disorder and certain forms of epilepsy. Its oral formulation allows for convenient long-term management of chronic neurological symptoms.
