Intra-Cellular Therapies to Present Data on Lumateperone

This is the first I’ve heard of it being investigated for substance abuse. I didn’t know it acted on opioid receptors.

Kava works on opiod receptors and it has a street reputation as an anti psychotic.

Did you know; when you cry, endorphins flood your opiod receptors ?

I’m guessing this med will try to treat the negative symptoms of SZ, primarily focusing on depression.

Imo.

That is their other drug, ITI-333.

As far as I know, Lumateperone does not act on opiod receptors.

ITI-333 isn’t being trialed in schizophrenia, but wasn’t there some news on opiod receptor dysfunction in schizophrenia recently?

Thanks, I misunderstood. I didn’t catch anything about opioid receptor dysfunction in schizophrenia, but it could explain why people with Sz are at an increased risk for substance abuse disorders.

Reduced mu opioid receptor availability in schizophrenia revealed with [11C]-carfentanil positron emission tomographic Imaging

I don’t know whether this ITI-333 would help with that reduced availability or not. Not sure if it is an agonist or antagonist.

Edit: ITI-333 is a MOR partial agonist. I really don’t know what that might mean for schizophrenia.
