What else makes you angry in addition to escitalopram? Wouldn't your statements, which I have excerpted, below, apply with equal force, for example, to nefazodone, St. John's wort, omega-3 oils, anticonvulsants prescribed for depression, or SAMe?
> Why am I saying all this stuff? Because I am angry. My reading of the research is that XXX hasn't been proved to be superior to any anti-depressant. All independent bodies which have assessed the evidence agree, including the FDA Claims for this drug are being made which are just not justified, and they are legitimated by vague referrals to 'positive studies', which when you examine them closely don't really show convincing results.

If people believe they are being put on a far superior drug which is very effective against depression, how do they feel when it doesn't work? Often they will feel that it proves they have an untreatably severe condition, so they lose hope, are more depressed, and question whether it's worth continuing to try to change things.

>Dr. Dave,
Obviously, you are talking about treatment-resistant unipolar depressive patients who have had at least one or two trials with different antidepressants with little or no success (and understandably yearning for a new "miracle" medication). S-citalopram, possibly, at best, probably offers a very clean (low-SE profile) choice for a clinician seeing a "typical" patient (presenting for the 1st time) with a major depressive episode requiring medical attention. However, there will likely be the occasional treatment-resistant few who might respond well to an antidepressant switch to this medication (and a much "fewer" group-who might respond "miraculously" to this as opposed to s+r-citalopram). The pragmatist part of my thinking, says: "Go ahead and switch them around, play the musical chair game with the AD's, but you will get one or two, here and there, that get well, and that's worth the trials." You talk about "science" being corrupted. I understand your anger about that. So, do we spoil the occasional few for scientific idealism, to save a lot more from being disillusioned by fraudulent capitalistic opiates? Do we.. "let the buyer beware", "keep hope alive", "there's a chance it might work" or decide in advance that a treatment-resistant patient will *likely* not benefit from something new.. so no sense in trying it? What it all boils down to is-what's worse? Risk disillusioning and letting down a patient duped by advertisements from drug companies (when the drug fails to live up to the patient's expectations), or letting down the occasional rare (treatment-resistant) patient who could benefit from the medication.

There seems to be a question here... 10 = 40 This really means that 10 milligrams is equal to the EFFICACY of 40mg of celexa... right? If you can get a greater efficacy with fewer side effects then this would be a benefit... No? Is there such a thing as "too well" or "too much improvement?" This is my interpretation from what I have read so far. SSRIs are usually started low and titrated up to avoid side effects. I guess I'm confused on the 10 = 40....
10mg can not equal 40mg of medication.... But the results of 10 are greater than the results of 40.....

*** I dont get Dr. Dave...he says Lexapro is not tested. Most new drugs go against placebo...Lexapro went again placebo and Celexa! And did show improved efficacy. (If 10mg of Lex can do at least what 40mg of Celexa does...with fewer side effects, and with a cleaner drug-to-drug interaction profile, and with onset of action in 1-2 weeks...I would say that sounds like improvement.) Also, why are we talking about patent protection again? Lexapro is coming out now...3 years before a generic for Celexa is available...this is because Lex is proving to be better, and that's it...otherwise Forest could "milk" Celexa for awhile longer, then pull out Lexapro at the last minute...again...not what Forest is doing. And as far as marketing...I dont know what Lundbeck is doing in Europe, but in the US...it's like this. If a patient is not seeing the results they/or the DR. desires on any antidepressant (including Celexa), then switch to Lexapro, favorable s/e profile, lack of drug interactions, and rapid onset make Lexapro an attractive SSRI. And for new patients...the previous also applies, and since very tolerable, it's a good first try (only 6% of patients discontinued due to adverse events) If doctors usually switch from one AD to another 25+% of the time...6% would be a great improvement for them and of course the patients.

Hi DR.Dave, Nice site...I noticed is was about 2 years old...any chance of any newer sites that might list more recent findings/or drugs since then? And I'm curious...how do you feel about isomer science in general...do you believe that it's all about money and getting a "new" drug out to replace an old one, or do you believe there can be a benefit to the single isomer/enantiomer over the racemic mixture?

It is repeatedly claimed Lexapro has fewer side-effects than Celexa. What does the data show? In the Burke et al trial 85.6% of those on Lexapro 20mg had side-effects compared to 86.4% on Celexa 40mg (not statistically significant). Not impressive, I would suggest. 10.4% of those on Lexapro 20mg discontinued because of side-effects compared to 8.8% of those on Celexa. So in fact more discontinued Lexapro than Celexa. But the result is not statistically significant and therefore likely to be a chance result.
The incidence of discontinuations on Lexapro 10mg a day was 4.2% compared to 2.5% on placebo. Again, not statistically significant. The overall rate of side-effects on Lexapro 10mg was 79.0% compared to 70.5% on placebo (not statistically significant). The comparison between Celexa 20 mg and placebo is not available as this dose was not used.
So the Burke study provides no data to support the claim that Lexapro has fewer side-effects than Celexa.
Gorman gives discontinuation rates for Lexapro in both doses as being 5.9% versus 2.2% for placebo (not statistically significant). No equivalent rate for Celexa is available. No more detail on side-effects is given in this, the most comprehensive analysis of the data currently available. Myself, I ask why not, if this is such a step forward in terms of side-effects.
These results are entirely consistent with the hypothesis that there is no statistically significant difference in side-effects between Lexapro and Celexa, and provide no evidence of the difference that is so widely claimed as being an established fact.
If there is other evidence to fit into this overall picture, this must be considered, but these results seem to suggest very powerfully that there is no significant difference in side-effects.
Decide for yourself on the basis of actual hard facts.

Hard to believe a company is giving up over $5 billion over the next 3 years...I guess the message Forest is sending is that it that sure Lexapro is that good.

Lexapro will be available beginning 9/5/02. I would caution you about switching from Celexa to Lexapro immediately. If you are well controlled on Celexa and comfortable with the therapy, you may want to seriously talk it over with your doc. You are altering the reuptake of seratonin in your brain and psychopharmacology is no perfect science. If you switch to Lexapro it's quite possible your seratonin levels will rise considerably due to the potency of this new isomer. No doubt there is much to be excited about with Lexapro. Just don't take this decision lightly.
Much luck to you!

The important name to remember is citalopram - this is the proper name for 'Celexa', and anything generic will be called citalopram, plus possibly another trade name (like 'Celexa').

Gee,
I'm so glad that a drug rep has assured us that Lexapro is a better drug and that Forest is an ethical company. Now we can all relax. *Cough*
Forgive the sarcasm. It's just that we've heard this song and dance before. I'm on Celexa now. It works brilliantly. I'm going to insist that my pdoc wait for about a year or so to pass before even considering a switch to Lexapro. I'll let others be guinea pigs and wait it out.
Everytime I've made med changes my whole world gets upset for a while. I want to see what this transition from Celexa to Lexapro does to others before I allow Forest to experiment with my brain.
Take Care,

What is the significance of Lexapro receiving separate FDA approval as a “maintenance treatment” for depression? Aren’t all ADs, including Celexa, used for maintenance as well as initial treatment? Pharmrep, if you’re still out there, will there be new prescribing info for a maintenance dosage, of will the maintenance dosage be the same as the therapeutic dose?

Pharmrep - do you have any comments on my presentation of the data about Lexapro's side-effects compared to Celexa's?
I don't think I've ever said Lexapro hasn't been tested - I supplied links to lots of research in a previous post. Incidentally, I've been in touch with Jack Gorman about the conflict between the poster and the paper in terms of end-point LOCF score, and he says the poster is wrong.

I am surprised that someone eager to make a case against escitalopram keeps pressing the Gorman study. If you're depressed and considering Lexapro and you read the Gorman study, you will camp out on the sidewalk of your drugstore to be the first in line on the morning of the 5th. This is the first paragraph of Gorman's conclusion:
"The results of the pooled analyses clearly support the previously reported antidepressant effect of escitalopram. Additionally, these findings suggest that escitalopram may be superior to citalopram, in terms of both speed of onset and magnitude of its clinical effects. The early and sustained antidepressant efficacy observed with escitalopram was achieved with doses of 10-20 mg/day, which have reported to be very well tolerated."

Let me try to clarify - I am not trying to make a case against escitalopram. I am making a case against the claims that it is any different from citalopram. I think they are effectively identical.
When reading a study you need to understand who's writing it, and look at the actual results. The Gorman et al study was co-authored by two Forest employees, one of whom is a medical writer. It is not surprising it is enthusiastic in its tone. If you were to read an advertisement for a product in a magazine saying it was much much better than other similar products, would you automatically camp outside a store for it, or would you want to know more about whether those claims were justified?
To see whether the claims are justified, we look at the figures. It seems clear, from the figures which I have given in a previous posting, that there is no significant difference in side-effects. Indeed new research presented this week (Raines et al) looking at people switching from citalopram to escitalopram did not show any significant reduction in side-effects.
This leaves the issue of efficacy. Gorman's study shows no significant difference between citalopram and escitalopram at end-point when drop-outs are accounted for (LOCF analysis). While a significant response after one week is reported, this has been previously reported and used as a selling point for citalopram.
I quote the Gorman study (and other studies) because this debate should be about the scientific evidence that is avilable. The important thing is the truth, and I believe that lies more in the research data than in the opinions of those aiming to promote the drug.
Material produced by drug companies needs to be carefully analysed because (and excuse me if you find this shocking or hard to believe) it can sometimes be a little biased.

What I hear you saying is that Gorman's data do not support his conclusions. Fair enough. I know this is a naive question, but how does he get away with that in what looks on the surface, at least to a non-expert, to be a scientific paper? I know these papers are generated and collected to serve the purposes of the manufacturers, but are they first published in journals that are "peer-reviewed" and offer a venue for criticism? The link you posted was from a manufacturer web site, but the document itself says "academic supplement." How is a lay reader to know if the thing was published in a reputable publication? I mean, if what you say is true, do you have the opportunity to send a letter to an editor and bust his lying ass (arse)?

** maybe I dont get your question, but here goes...Since only 2 doses..10 and 20 mg...Lexapro has a starting/maintenance dose of 10 (this is so that your Dr doesnt just go up to 20 because its available). Most patients will be ok staying at 10mg. Compare this to Celexa...most are ok starting at 20, then go to 40, and even fewer go higher.

Why are you comparing the higher 20mg of Lexapro to 40mg of Celexa when its 10mg of Lexapro that should be your comparing point? Do you normally start your patients at the highest dose? You should compare 10mg Lexapro to 40mg of Celexa since that is where the studies show that "10mg of Lexapro is at least as effective as 40mg of Celexa" Of course if you look at the 20mg of Lex then you will see higher side effects than the 10mg. But as you said...not a statistically significant difference than placebo. That is a good thing, so why the complaint...the FDA even allows the statement in the package insert. Maybe it would have been easier for you if Forest just compared Lexapro to Placebo like most new drugs that come out. Since Celexa and placebo are in the comparison, and Lexapro does show a significant statistical difference ahead of both...you seem to think there isnt. Stop trying to find a reason why you disagree with the studies...and be a little more objective, or better yet...let the folks here in the US have the chance to decide for themselves if they want to try Lexapro...since you arent willing to and have had the chance for some time now.
