Form the article ...
Quote:
The glutamate receptor subtype known as N-methyl-D-aspartic acid (NMDA) plays a central role in modulating aspects of brain activity, such as synaptic transmission, synaptic plasticity and excitotoxicity. Major pharmaceutical firms have been developing NMDA receptor modulators for more than 20 years, and a few, including Memantine®, ketamine, D-cycloserine, and dextromethorphan are marketed for other indications, generating annual sales of more than $1 billion. The antidepressant potential of modulating the NMDA receptor has been confirmed by data from clinical studies with known NMDA receptor antagonists, which produced reductions in depression scores in patients with treatment-resistant depression. The efficacy in these studies was significant, with response rates of greater than 50%, fast onset of action within hours of a single dose, and a long duration of effect lasting as long as seven to 30 days after a single dose. These data have confirmed the NMDA receptor as a novel target of high interest in depression - representing a potentially entirely new way to treat patients who do not respond to current therapies. But the known NMDA receptor drugs are also associated with significant toxicities at doses that are very close to the therapeutic dose.(3), (4) These side effects include schizophrenia-like effects, sedation, and abuse and addiction potential, perhaps best illustrated by the fact that ketamine has achieved notoriety as a drug of abuse. Until now, the narrow margin between therapeutic effects and adverse effects has limited the therapeutic potential of these agents. In studies to date, Naurex's novel NMDA receptor glycine site functional partial agonists have shown the significant therapeutic efficacy of other NMDA receptor modulators but without their limiting side effects.

This is great. Always good to see NMDA agonists making inroads against depression. Also, I feel like I recognize that company's founder, Joseph Moskal, from elsewhere...anyone else heard of him before?

Interesting read though I'm curious as to what kind of mood it puts the person in which based on other drugs that target the NMDA receptor, I'd imagine it's just a blank, feeling ok state.

Actually dissociative drugs have an antidepressant effect lasting approximately a week after a dose which is not especially dissociative in nature. In some countries oral ketamine is prescribed as an antidepressant.

Hm, I can easily see how that works with how depression causes a chemical inbalance though I wonder what it's effects are in someone who is not depressed. Perhaps similar to traditional anti-depressants when you take them if you're not actually depressed?

I notice powerful antidepressant effects from DXM; after a singe dose (at any plateau, but most notably at 2nd plateau doses) I have a strong mood lift and outlook-betterment for around two weeks.

It's a very good medicine.

Looks like the Phase I clinical trial for this drug is still recruiting. Where do I sign?
