Remacemide hydrochloride is primarily used in the field of neurology and pharmacology for its potential as an antiepileptic agent. It has been studied for its ability to modulate NMDA receptors, which play a critical role in neuronal signaling and are implicated in epilepsy and neurodegenerative disorders. By inhibiting excessive NMDA receptor activity, it may help reduce seizure frequency and severity in patients with epilepsy. Additionally, research has explored its neuroprotective properties, suggesting it could be beneficial in conditions like stroke or traumatic brain injury where excitotoxicity is a concern. However, its clinical use remains limited, and further studies are needed to fully establish its efficacy and safety profile.
