Nortriptyline is the main active metabolite of amitriptyline, so I don't think it's for me. I imagine it will be much like amitriptyline but with less anticholinergic activity.
No, it is not like amitriptyline which is as serotonergic as some SSRIs with a serotonin transporter binding potency of 20 Ki
, whereas nortriptyline is one of the least with a potency of 100 Ki
(the lower the Ki
the greater the potency). However, you're correct about the anticholinergic activity, it's a far less.
It's also more activating than amitriptyline, which is not a good idea for me. I found amitriptyline to be activating even at a low dose.
It is marginally less sedating than amitriptyline, but most, though not all, find it sedating.
If anything, I need my noradrenaline levels lowered/blocked. Drugs like venlafaxine were a nightmare for me.
Unless you were taking 150mg plus it would have had little if any effect on noradrenaline. Its noradrenaline transporter affinity is up to 6,300 Ki
. It was just another SSRI. None of the antidepressants you've listed has an appreciable noradrenaline impact.
No, I am resolved never to take another antidepressant again. They just don't agree with me.
I guess I'll just have to see what my psychiatrist has to say.
On the subject of people developing dependence on antidepressants, you might find this paper interesting (if you haven't already seen it):

They are right, it isn't rational. Indeed, the entirety of the debate about benzodiazepines for anxiety is irrational. Unlike the debate about their use for epilepsy which is almost all rational. Withdrawal is mostly a non issue despite the much higher doses taken by epileptics.
In a number of studies1
since 1992, Charles Medawar, a noted UK pharmaceutical safety researcher has repeatedly found that the number of "Yellow Card
" reports of adverse withdrawal effects involving antidepressants, mostly Paxil (paroxetine) and Effexor (venlafaxine), exceed not only that for benzodiazepines, but all other meds combined in most years.
