Atomoxetine and kappa-opioid-receptor agonism

Posted by Helena24 on March 23, 2010, at 16:55:07

Hi,(sorry for my bad English).
I'm currently on 10 mg Strattera and experiencing strong dysphoria (wich I'm managing with diazepam and Tianeptine).

A few years ago I startet taking 40 mg Stattera but I had to quit shortly due to extreme somnolence and irritability.

I have ADD and depression.

Now I learnt that a second metabolite of atomoxetine is a partial agonist on the kappa opioid receptor (the stimulation of it is thought to decrease dopamine function in the striatum).

Could the dysphoria be because of this action?

I have been on desipramine bevore and it didn't cause dyspohoria (it's not available were I live).

I never tried reboxetine.
Is there someone who took both ,Strattera and Reboxetine ,a tell if this two drugs work differently?

Is a ''low dopamine deep limbic ADD'' (sorry if this is not a scientifical term) be worsened by a kappa agonism due to antidopaminergic action?

Could this be linked to the suicidility that Strattera sometimes causes?

I feel a stronger need to take more Tianeptine since I am on Strattera.Maybe because I need my dopamine function restored?

Thoughts?
