I thought SSRI's, as a drug class, were very weak reuptake inhibitor of norepinephrine to the point of very little impact on norepi unlike SNRI's.....
Can someone clarify this for me?

> Can someone clarify this for me?If I recall correctly, Paxil is supposedly the most potent NRI that is classified as an SRI out of the drugs available in N. America. There has been some really huge arguments over the past few years about it even labeling Paxil, Prozac, Zoloft et al, as just "SSRI's". Some of their strongest characteristics may be the influence on Serotonin, but they certainly have been shown to affect numerous/and/or most .at least some of the other neurotransmitters. It all really came down to marketing. The drug companies wanted to present a "clean" a.d. that addressed their (ill thought-up) idea that Serotonin is/was the only major player in depression.(This is particularly true going back to the original launch of Prozac here in N. America. Prozac also effects both some dopamine and norepinephrine. EVERYTHING was linked to Serotonin) It is just they all have different "ratios" of how much the drug affects a particular neurotransmitter. Yes, some affect Serotonin more then others, but "SSRI" may be misleading.

False advertising. Love Phillipa but would explain why most hype me up but not luvox but be the only true SSRI.

I don't think so. Life is not a series of either/or, all/nothing, black/white, good/bad, yes/no, or other dichotomous decisions--not even for any one person. It's much more complex, as are neurochemistry and pharmokinetics.

Low dose luvox works for me no side effects the only one so it's my drug of choice. Love Phillipa

I'm glad it works well for you. But it's not "the only true SSRI." That's what I was commenting on.

Hi Glydin,
I was once told that celexa is the "cleanest" SSRI in terms of the effect on serotonin. That would include lexapro as well.
Nellie.

GG I know that is my point so why are some saying norepenephrine and dopamine? As far as I know all the above mentioned are SSRI's only SNRI's being effexor and cymbalta. Love Phillipa
