I have to admit I'm a little confused. Maybe I don't understand english all that well....
The investigators observed continued improvement in subjects with further reductions in the MADRS and CGI-S scores. ****The incidence of adverse events declined during escitalopram treatment versus short-term treatment. ****There were no clinically significant mean changes in vital signs, electrocardiogram (ECG), or laboratory values observed during continued escitalopram treatment, regardless of previous treatment. Researchers observed no new clinically significant adverse events in patients switching from citalopram to escitalopram treatment.
"In patients switched from citalopram to escitalopram, there are no safety concerns, and depressive symptoms continue to improve." the researchers concluded.
Hardly sounds like a negative...

This discussion definitely brings up POLICY issues for sure. I was certain this was going to wind up being political (socio-politico-economics of psych medication) when I saw a beatup pickup driving through town with a bumper sticker that said "HAVE YOU TAKEN YOUR LAZY PILLS TODAY?".

Anyway, the Lexapro number is 9%...it is believed to be slightly lower than Celexa, due to its increased Serotonin selectivity (there seems to be a connection to the more selective, the less the sex. s/e.) Ultimately, any AD working with serotonin will affect sex s/e. It's just a question of how much.

Let me explain again. I haven't seen evidence to support the claim that escitalopram has fewer side-effects than citalopram. I have presented all the data that are available on relative side-effects in a previous post, and they don't support this claim.
People are now claiming that Raines et al shows escitalopram has fewer side-effects than citalopram. I am not sure how you can come to this conclusion when there was no comparison made. If there is anything in the study that does say it has fewer side-effects than citalopram, I haven't seen it.
All the studies available show no significant difference in side effects between escitalopram and citalopram. If Raines et al does give evidence to contradict this I would be glad if someone could say what that evidence is. Escitalopram having a low level of side-effects is great but unless you know what level of side-effects citalopram would give under the same conditions, you don't know if there's any difference.
It is not enough to read a diffusely enthusiastic tone in a paper and then take this to mean every claim made about the drug must therefore be true. Things can only be taken to be true if there is evidence that they are true. To show that there is a difference in side-effects between escitalopram and citalopram, present the evidence.

In reply to Fewer s/e with Lexapro - where's the evidence? » pharmrep, posted by dr. dave on September 3, 2002, at 5:41:52
The way I see it, a switch from Celexa to Lexapro would be prudent. Celexa has a drug in it (the R-enantiomer) which apparently has NO antidepressant activity. In fact, it may be harmful in terms of making the active ingredient less effecive. And also it might cause side effects. Why would anyone want to take the R-enantiomer? Why put a drug in your body that is not helpfull and that might be harmfull?

I have never taken an ssri and need to switch. What do you mean when you say sexual side effects? Lack of desire?, feeling?, etc. Also, would it be desirable to titrate up very slowly with lexapro to decrease the chance of initial anxiety? I have heard it can be a problem at the start and I want an AD with anxiety relieving properties. Anybody feel spacey on Celexa? Remeron made me a space cadet. Thank you

It doesn't make a hell of a lot of sense does it? And if you do get side-effects in the first week and no benefit, that means pretty much nothing because the side-effects are likely to go and it hasn't had time to properly kick in yet.
I suppose there's nothing to stop anyone posting anything they like on these boards - maybe every other SSRI manufacturer is posting that they've tried Lexapro and it's awful. You never know what tricks these guys are up to.

I didn't think about any dirty play from other drug companies. The only thing that bothers me is when I look at a lot of ssri's I see poop out happening(or so it appears) to everyone over time. Why start something if it will just poop out? I would like to change to a new AD since my nortryptline makes my sleep and mood worse when I work out. And I need to excercise to help myself. It might take a few days, but over the last few years all mood and sleep disturbance has occurred when I have tried to work out. My doc doesn't quite buy it, but I have found other people with similiar experience on nortryptline and amitryptline. It is almost like the AD causes depression??? I know it sounds funny, but that is the way it feels sometimes. I have not heard of anybody feeling this way on Celexa or any other ssri's so that is why I am considering Lexapro. I tried remeron, but too powerful, and caused a sponge head feeling. Thanks for your input on ssri poop out if you have had experiences with that.

John,Just an aside here, but I found that nortriptyline and Celexa or nortriptyline and Zoloft work well *together*. The tricyclic didn't do much good by itself, and SSRI by itself doesn't work for me. You might try a lower dose of NT combined with an SSRI.

I haven't really found that people on SSRIs are more likely to relapse than people on other antidepressants. I do find that people can feel better on an antidepressant for a while and then relapse - which doesn't necessarily mean the drug has stopped working.
Antidepressants can successfully elevate an individuals mood, but it can be the case that the factors that have led to that depressive state in the first place can continue and overwhelm what effect the drug has had. I don't think people's mood state can be permanently elevated by a drug such that other influences cannot have an effect. If someone's life is chronically difficult, be that because of external problems or because of unhelpful ways of thinking or reacting to circumstances, this can lead to depression. Antidepressants can alter the balance of positive and negative influences on that persons mood, but if the difficulties continue they can reverse that shift. If your life has felt devoid of pleasure for six months, that exerts a certain downward pressure on your mood. If your life has felt devoid of pleasure for six years, that is going to depress your mood more strongly. In this situation the pressures that are chronically exerting a negative influence on your mood need to be identified and sorted out, as any medication may be fighting an unwinnable battle.

Dr. Dave, you seem willing to discuss different factors regarding depression. If you wouldn't mind, could you please email me at isomorphix at hotmail dot com (in the normal mode - this is to hopefully stop my email add from showing up in searches). I will not be a bother but wish to privately ask a question regarding ADs, self-esteem, & life style. Promise that there would be no 'hounding' you with many further questions.

Thanks for responding. I do agree with what you said about overwhelming factors. And I have had that this past year. But, not working out doesn't allow me to help myself.
Ritch, I will have an overlap when I start (maybe) lexapro while trying to change over.

You have mentioned the Sanchez paper which shows Lexapro raising brain serotonin more than an equivalent dose of Celexa. This seems to show r-citalopram impeding the action of s-citalopram.
But there is another side to this. Another paper by Sanchez compares the potency of Lexapro and Celexa. The results are in terms of IC50 - the concentration required to inhibit serotonin re-uptake by 50%.
2.1 nM of Lexapro inhibits re-uptake by 50%, whereas 3.9 nM of Celexa is required. So Lexapro is about twice as potent. But let's think about this. Once Celexa is absorbed, you end up with 36% s-citalopram and 64% r-citalopram in the circulation. So the concentration of s-citalopram needed to achieve 50% inhibition, when r-citalopram is also present, is 36% of 3.9nM - only 1.4nM!
So from these results, r-citalopram helps s-citalopram with serotonin re-uptake inhibition! This is pretty definitely not true, but it demonstrates how unreliable individual results can be, and if you pick out the right results you can make them say all sorts of improbable things. This is why I feel it is so important to look at all the data.
I think we should be able to examine the trials which have been done comparing Celexa and Lexapro. Currently (as far as I am aware) the comparisons from only one of three trials has been disclosed (Burke et al). The study written up by Lepola et al and Montgomery et al has had the citalopram data removed, for no apparent reason. The third trial has not been disclosed at all.
I think we should be able to have access to all the information so we can make up our own minds.

Lexapro has the cleanest cyp450 system (liver metabolization) of all AD's. Celexa was the cleanest before, only mild inhibitions in the 2d6 and 1a2...Lexapro has 0 (negligible) inhibitions in all the pathways..3a4,2d6,1a2,2c19,and 2c9
(In otherwords...it is nearly impossible to get a drug-to-drug interaction with Lexapro...which is good news for anybody on multiple meds.)

You need to ask your Dr about Lexapro...Forest is going to start giving the Dr's samples and studies starting 9/5...there can be sexual s/e with AD's that affect serotonin. Lexapro showed a 9% possibility of have ejaculatory delay (not always a problem). But it was not enough to discontinue treatment (only 6% dropout rate for various reasons.) As far as titrating goes...couldn't be easier...everyone starts at 10mg...most patients should see a difference in 1-2 weeks, and if necessary go to 20mg, but that should be necessary for a minority of patients...most will do fine at 10mg. As far as anxiety...Lexapro will help that, not contribute to problems. Look for the Burke, Gorman, and Lydiard studies for proof-sources.

"Evidence" for you is something different than "evidence" for a potential user of Lexapro and also different, I'll bet, for most practitioners. I'm not trying to win a scientific argument. I am trying to make reasonable and, I hope, effective decisions about which medicine to take for a mood disorder. "Evidence" for me means "useful information." For the moment, the best such evidence about Lexapro is the FDA-approved prescribing information that says that the incidence of adverse effects associated with a therapeutic dose of 10mg Lexapro is the same as placebo. That's pretty good reason to believe that Lexapro is worth a try, as compared to the FDA-prescribing info for the alternative SSRIs. In a couple of months we'll have additional "evidence" in the way of the reported experience of Lexapro users and prescribers.
