What drug is an antagonist for glutamate?
Glutamate Antagonists Those with potential clinical efficacy include dextrorphan, dextromethorphan, licostinel, and magnesium.
What does blocking glutamate receptors do?
Mechanistically, antagonist-mediated blocking of NMDA receptor (hypofunctioning) leads to the excessive release of excitatory neurotransmitters (glutamate and acetylcholine) in different brain regions, which in turn causes hyperstimulation of postsynaptic neurons and subsequent induction of psychotic conditions.
How does Mg block NMDA?
While the opening and closing of the ion channel is primarily gated by ligand binding, the current flow through the ion channel is voltage-dependent. Extracellular magnesium (Mg2+) and zinc (Zn2+) ions can bind to specific sites on the receptor, blocking the passage of other cations through the open ion channel.
What drug is a NMDA antagonist?
Commercially available NMDA-receptor antagonists include ketamine, dextromethorphan, memantine, and amantadine. The opioids methadone, dextropropoxyphene, and ketobemidone are also antagonists at the NMDA receptor.
What drugs decrease glutamate?

How can I lower glutamate?
Relaxing herbs such as lemon balm, chamomile, and passion can offset the negative effects of glutamate by restoring its balance with gamma-aminobutyric acid (GABA).
Does NAC decrease glutamate?
2016), and where, in preclinical studies, the administration of NAC reduces glutamate levels (Baker et al.
