>Some people become dysphoric. They don't need more endorphins help.
Some of the people who become dysphoric after a single dose become euphoric after repeated doses. In the same way that response to an SSRI does not prove that a person has serotonin deficiency, response to an opioid does not prove that a person has endorphin deficiency. It's unwise to presume that we understand so much.
>Other people however go from depressed to normal...pure normal...not high, not drugged, not euphoric, just plain normal...THAT is an easy diagnosis.
It's not a diagnosis, it's an assumption - an assumption that endorphin deficiency is the underlying problem. Again, it is unwise to presume that we understand the mechanisms behind such a response. Unfortunately, an excellent acute response to an opioid does not mean that the benefits will last. They might do, or they might not. I think that's the same with just about everything ie. the long term response it impossible to predict with any accuracy.
>Except that...LDN or DLPA have a very high likelihood of coming close to the same result...
I doubt that a response to Vicodin can predict response to LDN or DLPA. LDN, opioid agonists and DLPA have different mechanisms of action. A response to Vicodin might predict a response to say, oxycodone, because these drugs have the same mechanism of action.
>That same patient staying instead with the ssris, antipsychotics, and mood stabilzers, is probably going to remain ill for a long time.
I fully understand the need for new and novel treatments for psychiatric illness. I do not dispute that.
I think you have a tendency to present theory as if it were fact. This is what I disagree with.

Just like the neurotransmitter theory of depression?
I said to my shrink that the neurotransmitter hypothesis was dead and he perked up immediately and then we talked about psychopaths in high places.

I was in the hospital and doing a two-week washout from ensam so I could start parnate. I was severely depressed. I asked the p-doc there if I could try suboxone. Opiates kept my depression at bay for five years (self-precribed, using higher and higher dosages. I got off them by working with a suboxone doctor). Suboxone can't be used to OD (contains naltrexone) and it's hard to use higher and higher dosages also because of the naltrexone and because it's taken sublingually and because precriptions are carefully monitored. She said she would consult about it, but by that time, I was on parnate and felt fine within 48 hours.

I agree with everything you have said. In fact, everything stated could apply equally as well to a discussion of any other neurotransmitter or drug. But all that was off the path. It appears that the primary body of the message was completely missed. Took some sidepaths and completely lost the main road.

I think the message is that we should be willing to try something different and novel when the usual treatments haven't helped? Trying the 6th SSRI after 5 haven't worked isn't likely to be effective!

Opiates like codiene and morphine act as fairly potent sigma-1r agonists. Sigma agonists have documented antidepressant, anxiolytic and cognitive enhancing effects.
Whose to say that the "AD" effect of opiates is not related to other targets of select opiates?
As eluded to, some studies suggest increased opioid like activity in depression. Socially defeated "depressed" animals show increased MU opioid neurotransmission.

Do you think that this might be an effect secondary to the stimulus rather than a cause of the depression? Perhaps the numbing effect of opioidergic neurotransmission is protective against psychic pain. Just thinking...

That's true, Scott. Unsure if this is in context with what Linkadge said (?), but it is true that the brain releases opoids when psychic pain is too overwhelming - dissociation is a primary example.
If at a young age you experienced overwhelming psychic pain leading to repeated dissociation (I have) the brain's 'hardwiring' does not develop as a normal child's.

Certainly people in extreme mental states can find ways of comforting themselves, rocking themselves to sleep and developing bony calluses on the foreheads like autistic or deprived kids do, losing themselves in sounds they make and other things, fascinating, isn't it?
There's that theory about autism and some milk protein which acts on opiate receptors?

Well yeah, depression is complex. Depression is not a single condition, it's a group of conditions which have similar symptoms. There are probably many different causes. Anyone who claims that 'depression is caused by low serotonin' clearly has no idea what they are talking about. Even if a subset of patients were found to have low serotonin (difficult to measure), this obviously won't apply to everyone. SSRIs are known to be effective for a proportion of cases of depression. This does not, however, prove that low serotonin was the cause of their illness. This sort of backwards logic is not very scientific. Opioids are effective for pain but that doesn't mean that the pain was caused by low endorphins!

If it's good enough for serotonin, it's good enough for opiates :)
I'd trade 95% (too low?) of psych drugs for opium.
These days I might even be able to use it twice a week, you know, if I hadn't etc etc etc

SSRIs actually don't raise serotonin
"In this study, we demonstrate that chronic treatment with citalopram, a widely prescribed and highly selective SERT inhibitor [3], [26], causes a suppression of 5-HT synthesis in the mouse brain"

>but ed, I am sure you know all about dr. bodkin's "experiments" with buprenorphine back in the 20th century (haha), and he's still practicing it.. delta agonists have clearly been shown to exhibit antidepressant effects in mice, some tricyclics (definitely amitriptyline and nortriptyline) increase endogenous activity at delta receptors which contributed to their usefulness in pain, but very probably also to their high efficacy in depression, and one could go on like that.. these are facts, and I guess there is not one statement on here with which I agree more than when bleauberry said it would be irresponsible to not add the endogenous opioid system into the equation.. some patients with TRD show totally paradox reactions to opioids, i.e. feeling normal as was said, but also having less problems going off of them.. I didn't talk about it much because I wanted to make one comprehensive post about it, right now I just do not have the energy for it: I did try buprenorphine for the past 4 months, dosage up to 9mg/d (maximum in TRD is around 12mg/d).. it DID work in the beginning, and that was NOT due to the general opioid euphoria.. this euphoria is mu-receptor-mediated, and buprenorphine plasme levels peak at 45min to 1 hour after intake (sublingual).. also, "recreational" users say the effect is strongest at about an hour.. my improvement started some 4-5 hours after taking it - and subsided some 4-5 hours later.. I was very confused, until I found out that the response I had was basically identical to the plasma level over time-curve of nurbuprenorphine, the active metabolite, which is a delta-agonist.. but it has a much much shorter halflife, and so the effect disappeared quickly.. unfortunately I was not able to reproduce it after the first one to two weeks.. now I wonder what conclusions to draw from that... also, I was not "high", I cleaned up my kitchen for the first time in quite some time, and I did not only finish what I set as a target, but I looked for something else to do because I was quicker than I expected.. now I say I do "this", and ten minutes into it I am just unable to go on.. this is so disappointing... unfortunately, I think that there is no specific delta-agonist that I could try out to verify my hypothesis... but I have no doubt that there is something about it, and I think it's more than just a hypothesis that has yet to prove it's value.. it's by far no solution for everyone as I just experienced, but it is a solution for some... it scares me that it isn't one for me, who knows what will work instead, or if anything will work at all...

Certainly what you say here.........

is broadly consistent with what people on bupe maintenance report as compared with methadone maintenance...that it is less depressing.
As you would know, a proportion of such people are self-medicating for depression.

The tcas also have kappa agonism and NMDA antagonism. This might produce an anti-tollerance effect.

>
kappa-agonism is bad though.. well, talk about reductionism, but, in general kappa-agonism produces dysphoria.. that's why the development of kappa agonists for non-mu-pain medication was not pursued.. kappa-antagonism may be good, well it very probably is, and guess what, buprenorphine is a kappa-antagonist..also, what I forgot to say yesterday, going down from 9mg to doses less than a mg in rather quick steps produced absolutely no withdrawal in me.. I wanted to get rid off it even quicker to start a new med, but I told myself to be patient, not take a risk of withdrawal and not disturb my endogenous opioids too much by quitting all at once..

I know what you mean. If agonism of a particular receptor was universally bad, the receptor would have no purpose - and would presumably not exist!

If agonism of a particular receptor was universally bad, the receptor would have no purpose - and would presumably not exist!yeah, I was thinking of you when I said "reductionism" actually... because who knows what indirect effects kappa-agonism has.. like when 5-HT2c antagonism releases more dopamine in the prefrontal cortex upon stimulation (mirtazapine, agomelatine,..)..
did you read my post above that I wrote to you? feel free to comment on it.. i.e., do! ;-)as for sigma-receptor antidepressants (in fact, sigma-receptors aren't opioid receptors but I guess that doesn't matter), there is already one, it's called opipramole.. I think it's not available in the US though.. it's also used for anxiety, where it was shown to be only insignificantly less effective than alprazolam..

Hello.
>I guess there is not one statement on here with which I agree more than when bleauberry said it would be irresponsible to not add the endogenous opioid system into the equation.
Oh I agree. I suppose the major problem at the moment is that all currently available opioids have significant disadvantages which prevent their widespread use in psychiatry.
>I think that there is no specific delta-agonist that I could try out to verify my hypothesis...
No, I don't think there is. Also, I believe that norbuprenorphine is active at several receptors - so it's difficult to draw any conclusions.
How do you respond to the TCAs that you mentioned above?

I don't care what anyone says, the best meds I've ever taken that have obliterated my depression have not been AD's.
Low doses of oxycodone, like 2.5mg prn or twice daily is fantastic. I only ever take Endone which is pure oxy in 5mg tabs.
Low dose ritalin prn, or 2.5mg daily around lunch time or just after, somedays I need up to 30mg, somedays nothing.
DA's, but they make me really sick.
Modafinil, prn 100-200mg
I am on 5mg of clonazepam daily which I know is high but it keeps me sane and level headed. That will take me quite some time to come off as I know I'm dependent on it. When the time is right I'll come off. I'm aiming for 4mg daily at the moment. I'm down from 6-8mg daily but it works for me.
So who cares if you get addicted to your meds? I used to have huge issues with it but as I have grown older. I don't care if it helps me feel better.
