Stratteras increase in NE = increased DA?

Posted by hello123 on January 8, 2015, at 17:54:49

this is a bit of a technical question, but ive read that increasing Norepinephrine can have a downstream effect of increasing Dopamine. How does this increase in Dopamine actually occur? ive tried finding an article describing it, but cant find anything on Pubmed.

ive had a feeling NRI's have an indirect effect on Dopamine after my experience with a few SNRI Antidepressants, but my experience felt more like a severe *decrease* in Dopamine instead of an increase. After about 3 days on SNRI's ive experienced a severe decrease in ability to feel pleasure thats very different in the numbing effect an increase in Serotonin has. But the decrease in pleasure ive experienced from SNRI's has caused me to stop the med after the length of time that is typical for a full med trial. And my pdoc prescribed Strattera for Depression today and im hoping i will be able to give this a full trial. Does anyone have exoerience with meds that increase Norepinephrine causing worse Depression the first few weeks, with mood improvements after that?

From what I understand, the prefrontal cortex lacks dopamine transporters. Instead, the norepinephrine transporter works to uptake dopamine in the prefrontal cortex. So, in the prefrontal cortex, a NRI can increase dopamine levels.

yea....but it's indirectly ... NE makes you more alert, improves attention, and when your alert and have more attention your more likely to do things that require motivation, and pleasure.....then that's kinda how dopamine get's envolved through activities that require dopamine to think, and get things done

have to search more on the physics of how NE links to dopamine through chemical interaction

yes it's quite correct. Norepinephrine neurons also utilize dopamine, so when the reuptake is blocked, not only norepinephrine but also dopamine is boosted in synapses.

> How does cymbalta help pain since has norepenephrine?

Various drugs which act as norepinephine reuptake inhibitors, like Cymbalta and tricylic antidepressants are useful in chronic pain. The might act to reduce the transmission of pain signals in the spinal cord, but there are likely to be multiple mechanisms of action.

ive figured feeling better emotionally is what helps chronic pain. from my experience, when my depression is intense, just the pain from bumping into something is more intollerable than when im feeling okay emotionally. When im feeling good, the pain from it doesnt bother me near as much.
