where do I mail the reply... maybe to spammer at sellout.eli.lilly.profit.com???

Fact is, Zoloft is *far more* selective than prozac... while prozac has 
been arguably demostrated marginally better at improving depression than 
Zoloft, and may be effective at lower doses for many forms of depression, 
this is because of the slight norepinephrine boost that Prozac provides 
and Zoloft does not!!! Zoloft is simply a drug that does its job too well.

What am I saying? that a patient who responds to Zoloft somewhat, but not 
entirely, but receives nothing from a dosage increase of zoloft alone may 
benefit ENOURMOUSLY from the addition of a small amount of Wellbutrin or 
one of the TCA antidepressants. Why? Because they target other systems - 
systems somewhat targeted by Prozac because Prozac is less selective.

My personal experience is totally different. I reacted to Imipramine 
(alone) with severe paradoxical depression and no improvement in any 
area. Prozac didn't do much for me either, but Zoloft curbs my 
aggression/violent desires very well. Prozac is too jittery for me - 
although with the way I take caffeine maybe its an interaction. Suffice 
to say I disliked it. It wasn't stimulanty, but JITTERY, like muscle 
tremors and stuff...

Anyways, enough spam... now for some biological stuff... a receptor 
binding list(!!!) backing up what I said..

As mentioned in the original article, these drugs typically have active
metabolites which may be significant.  Thus, actual in vivo activity may
be slightly different.

[speaking of metabolites, paxil has none that are active, zoloft's 
metabolite, while longer lasting is largely inactive, and Prozac's 
metabolite, extremely long lasting, is half as potent - making 
norfluoxetine the active drug!!!]
