So i'm for another ride on the med-go-round, this time with ADs for reactive depression. I don't pick up the script till tomorrow, but from memory, it will be Lexapro AM and Celexa PM. Now seeing as they are mostly the same thing, does anyone have any explanantion?

i'm not a psychopharm expert, so i'm not going to be able to give you the brain chemical names for these things, however, i'll try to answer.

cymbalta is a multiple reuptake inhibitor, whereas lexapro is a selective seratonin reuptake inhibitor. i don't think cymbalta works on seratonin. i could very, very easily be wrong about this. however, i think it works on the other ones. your pdoc may want to cover the full spectrum to make sure that everything possible is addressed.

She mentioned celexa as opposed to cymbalta you silly goose. (smiley would here if I was smiley)

This is strange because Lexapro is the new and improved celexa and is very similar. celexa is available generic but that's not really an issue. Are you sure it's celexa? If so maybe the doc has something in mind and wants to cover all the bases with that drug.

BTW Cymbalta is like the next generation Effexor which does affect serotonin along with norepinephrine and possibly a little dopamine.

BTW Cymbalta is like the next generation Effexor which does affect serotonin along with norepinephrine and possibly a little dopamine.

Effexor is primarily a serotonin reuptake inhibitor until the dose is ramped up to around 225 mg, when the noradrenaline reuptake inhibition

kicks in. I don't recall what plateau dopamine reuptake inhibition is supposed to start becoming noticeable, but DA can hitch a ride on the

NA transporter so YMWV. I'd guess that if you can't handle Effexor above 150 mg, you're probably better off with an SSRI.

I'm fairly certain that Cymbalta inhibits reuptake of both serotonin and noradrenaline throughout the normal dosing range, as does Milnacipran.

From what little I've dug up about the relative affinities of either one, both have a greater effect on serotonin than NA (but if NA-driven anxiety

is a problem, the NA effects may be far more apparent).

Celexa and Lexapro are basically the same chemical, complex enough to have two mirror-image forms even with the same basic

atoms-stuck-together-with-sticks structure. Apparently one of the two forms provides more AD effect with less side-effects, so the

parent company figured out how to separate the two from the production stream (not as easy as it sounds) and markets that as Lexapro.

I can actually think of a good reason to prescribe the two separately - sometimes an insurance company decides that a medication at a given

dose/formulation is 1/day, period, who cares what the patient needs! So you prescribe a second med that does the same thing, and try to

balance the two out. Instead of 2 oranges twice a day (which isn't on the formulary, and therefor verboten) you prescribe 2 oranges in the AM,

2 tangelos in the PM, and still get 4 fruits' worth of Vitamin C in by the end of the day.

I think Surmontil is a tricyclic, but I could be wrong.

Yeah, it is but aside from the generic TCA crap I can't find out a thing. Just trying to find out what to expect.

If SSRIs are a silver bullet, TCAs are a shotgun shell with a random load of shot. The stuff goes everywhere.

It is used in treating peptic ulcers, but the effect does not appear related to an antihistamine (H2) action

(PubMed abstract), although it is supposed to have some antihistamine effect (usually assumed for all TCAs,

but the reality is that the effect ranges from "gee, I'm a little zoned" to ;):):cussing: )

Trimipramine may not knock you out but it has been found to reduce sleep quality (abstract) via H1 antagonism. Interestingly,

Wikipedia notes no effect on sleep architecture (Wiki article)

There's a bit more action on noradrenaline than serotonin reuptake, so there may not be as much anti-sex,

anti-motivation, effects as a doubled SSRI dose might land you.

From some of the references I see, there might be some anti-psychotic effect too. Maybe not as good as a standard

AP/AAP, but enough for milder wierdness in the course of depression. That might put it in the category of "It won't

make you feel good, but you won't severely depressed either."

Thanks for that - fascinating stuff. Zzzzzz is good because I've been running on 1-3 hours sleep a night for two weeks or more. The celexa is supposed to be doing the anti-d bit (big time reactive depression right now), but I took the first dose mid morning and I feel like I was hit by a truck.

My understanding is that they figured this out JUST before the patent ran out... lucky them.

FWIW, I found the ghetto Celexa to be more effective than the Lexapro... but maybe I should give Lex another shot.

Do you sometimes get the same euphoria from lex?

And how the hell do you get rid of the sexual side effects... not that I'm getting any, but...
