Hi pharmrep,
Saw the note about Phil's combo, can't resist asking a question. For me Celexa is activating and causes insomnia. I take 10mg in the morning, and can't sleep at all unless I take something sedating at night. For now the sedating med is neurontin, but even with that I'm awake til 3am. Do you know of any better way to deal with the insomnia side effect from celexa?
Also, how does lexapro compare on insomnia? Sorry if you've answered this elsewhere, I didn't read the entire thread.

Insomnia was a problem only when dropping the Celexa dose. In the monograph, Celexa rates high in somnolence. If you search 'celexa sleepy' on this site, it's not uncommon.
Thanks for checking. I'll do some science stuff and seek an interpretation.

> Well, I got some general answers since they dont know you. But the one commonality I heard was you have some pretty high doses, and the feeling sleepy yet not able to fall to asleep til 3am.
> Everyone thought 400mg Wellbutrin was too high (going to 1/2 was something I heard a couple of times) Adderall at 40 came up too (2x 20mg's). The Dr's thought this was your insomnia problem. I asked specifically if Celexa could be the "relaxed/tired" culprit...they didnt think so...they often go to 80+ without the "tired" effect, but everyone is different. There was the strong belief that more likely that there are both activating and relaxing meds in you at the same time...at the higher dosing, you could be getting adverse events as well. Your Dr. may have more experience with these meds at the higher doses than the pool I spoke with, but one thing I would recommend is to see how each one of these meds metabolizes in to make sure they are in fact doing that rather that fighting for the same pathway in you body and just floating around...this causes s/e and adverse events as well...I'll give you Celexa...it's a very mild inhibitor of the 2D6 and 1A2 pathways in the liver.These are the adverse events incidence in the clinical trials (listed in the package insert) for Celexa vs placebo. I'm only listing those at 10% or greater or interesting #'s. (this is 8wk study) celexa (1063 patients) placebo (446)
dry mouth 20%/ 14
increased sweating 11 / 9
nausea 21 / 14
fatigue 5 / 3
somnolence 18 / 10
insomnia 15 / 14
yawning 2 / 0
**in the 6mo-24mo trial the numbers stayed about the same. except for nausea..cx=6% and placebo=10%.So Phil, you seem to have somnolence with Cx, and .tabi, you get insomnia. I hate that the same drug
can contradict itself in different people. I will get you some ideas to help next week. (I cant remember
the Lexapro #, but I think it was about 5 or so...FDA is saying "similar to placebo")

The FDA makes drug companies test their drugs for only 8 weeks. But most literature says a depressive ought to take an AD for about a year to make sure the depression is gone. Many of us here take these drugs for years and will do so for the rest of our lives (I'm one of those). It gives many of us pause when we think about that and the possible future ramifications of longterm use. I for one don't like being a guinea pig, but figure the only other choice is death. The chance of getting cancer or some other malady later on because of these chemicals seems like an unfair but necessary (not to mention expensive) alternative to ending my life now. Do drug companies ever go back and study longterm use? Will there ever be any reassurance that these drugs are "safe" save for the lack of reports and warnings if nothing bad turns up?

*** Responsible companies do long term studies as well...there are such studies for Celexa, and I know that Lexapro studies are being done as we speak. The good news about Lexapro is that it is not a foreign matter in the human body. It is half of the Celexa molecule, and has been used by over 30 million people for over 15 years in Europe and the US. As far as the "FDA 8-weeks", you're right, unless there is something obviously wrong, or no separation from placebo, it usually passes.

Sorry. I tend to disagee. A drug is a chemical. There are lots of things that are not foreign matter to the body but which cause disease just the same. Also, I appreciate your enthusiasm about what you sell, but I was not referring to Celexa specifically. I was referring to antidepressants in general. Witness the recent black box warning on Serzone and liver damage, for example. How many years has Serzone been on the market and how many millions of people have used it? That's my point. I remember when red dye #3 (or was it #5?) was withdrawn from the market and there were all kinds of things we couldn't have for awhile until they came up with a healthier shade of red. My memory is vague, but I think Kool-Aid had red dye #3 in it... Certainly, Wellbutrin, Remeron, Effexor, Celexa, Serzone, Prozac, Zoloft etc. have chemicals much less benign than what one would presume to be harmless food coloring...
Thanks.

Maybe I missed your point. Your original question was regarding long-term studies...I am saying yes, they exist for Celexa as well as other ad's. I am not selling here, so please stop saying that. I was making the observation that Lex is not entirely a foreign substance to the body, as perhaps other new drugs might be "new." Paxil is another one that is not new (just a lowered dose with a different release mechanism)

Hey Phil...got a new one today, you heard of this. 250-500 mg of testoserone given once per month. This is supposed to help "speed up" the process...if you know what I mean. I have also heard of the Wellbutrin add-on (called CEL-WELL) to help too.

Thanks for the information. You did answer my question re' whether there were longterm studies going on. That is good to know.
I understand what you are saying about Lexapro and foreign substances, although I still tend to disagree that because something may not be "foreign" it is safer or less dangerous. They still are chemicals we are adding to our systems that cause desired and undesired effects. We just hope that the desired effects outweigh the undesired ones.
I don't care to get into picking nits, but was is your phrasing re' Lexapro that prompted my comment about your connection with the company that produces the drug. You said: "The good news about Lexapro is that it is not a foreign matter in the human body. It is half of
the Celexa molecule, and has been used by over 30 million people for over 15 years in Europe and the US."I hope you will excuse me: I have worked as newspaper editor and as a PR rep for many years and am sensitive -- or perhaps overly sensitive -- to how things are said, phrased, spun. Phrases such as "the good news about..." and even "which has been used by over 30 million people in Europe and the U.S." strike me as a bit promotional, especially coming from someone in your line of work. If it had been some computer programmer or grocery store clerk who'd been taking it and liked it a lot, I probably would have read past it or chalked it up to enthusiasm or perhaps overzealousness. Trying to talk about a drug from a company that you represent without sounding as though you are promoting it puts you in a difficult situation in that whatever you say is apt to be scrutinized very closely here -- even though your intent is to help and not to sell.
Thanks again for the information.

Yes, that was indeed very interesting. It would be nice if more pharm. companies would be interested in attempting to market meds that are already available in other countries that could be helpful here. I am thinking of moclobemide for one (why doesn't Roche try to get FDA approval here?). Also, the active metabolite of nortriptyline (I think E-10 OH-nortriptyline), has good anxiolytic properties, downregulates 5-HT receptors, and has nil side effects (that TCA's typically have). Why can't that be developed? Marketing active metabolits of older drugs is becoming more common (fexofenadine and cetirizine, ie.).Mitch

I wish I had an answer to Mitch's question as to why the FDA won't allow new and better drugs here in the US., after all, the US drug companies do their testing in Europe. I thought it was interesting the FDA "reached out" to Europe and killed the use of Amineptine for Europeans (now it's only available in South America - at a high cost I believe). My only thought would be to "privatize" the FDA (there might be a lot more to the solution than that)- nothing could be worse than the current FDA mess.

Hi Mitch.
How have you been doing?
> It would be nice if more pharm. companies would be interested in attempting to market meds that are already available in other countries that could be helpful here. I am thinking of moclobemide for one (why doesn't Roche try to get FDA approval here?).
First of all, it is my impression that moclobemide is really not a terribly effective drug - either for depression or social-phobia. Of course, some people respond well to it, but the non-selective irreversible MAOIs generally demonstrate superior efficacy. It is certainly worth a try, though. You never know, right?
- Don't give up on moclobemide until you reach 1200mg.
- Do not eat any more than 50mg of tyramine at any one meal.I would be very interested to know what drugs you would combine with moclobemide. Zyprexa would be interesting.
I tried moclobemide in December, 1996. I reacted very, very badly to it. It exacerbated my depression to a degree worse than I have ever experienced. I was curled up in a fetal position on the couch for days, wimpering in pain. No thoughts. Just mental pain.
Roche conducted trials of moclobemide in the US for the indication of social-phobia. I guess they figured they had a better chance of getting the FDA to approve a drug for an indication for which few drugs had yet been approved. The results were poor. I spoke to the head of the US moclobemide project just before it was discontinued. He told me that it was dead and that the trials had been terminated. I doubt they will revisit it.
> Also, the active metabolite of nortriptyline (I think E-10 OH-nortriptyline),
Isn't the parent compound active? What are the differences between them? What other drugs downregulate 5-HT receptors? In what ways does this help with depression? Is it simply an observed association or is there a hypothesis as to how it contributes to producing a remission?
Thanks.
> Why can't that be developed? Marketing active metabolits of older drugs is becoming more common (fexofenadine and cetirizine, ie.).
For every 1 drug brought to market, 100 are synthesized, researched, and discarded for various reasons, including projected profitability. It costs 800 million dollars and 12 years to get a drug approved by the FDA. I imagine there are a few miracle drugs that have ended up in landfills.

I have been doing better this summer than I have in *many* summers. I think the L-tyrosine and low-dose Depakote+Effexor+Wellbutrin is making a big difference this time. I am sleeping Ok, and I feel almost normal for a time of year I typically am very depressed. Of course, I am forcing myself to exercise a lot more-so that is contributing too.>

I spoke to the head of the US moclobemide project just before it was discontinued. He told me that it was dead and that the trials had been terminated. I doubt they will revisit it.I was considering moclobemide precisely because it *is* weak. I hyper-respond to antidepressants, due to bipolar and to general med sensitivities. It wouldn't surprise me at all if I responded well to 75mg twice daily! You see I am only taking 12.5mg of Effexor and 18.75mg of Wellbutrin right now. Any more of either one of those disrupts my sleep too much, or makes me too tired or too wired during the day. The trouble I have with antidepressants isn't really response, it is tolerance and hypomania. Also, stimulants and short half-life AD's like Effexor seem to work better than longer-half life AD's. The longer half-life ones seem to cause a lot of early morning awakenings and resultant daytime drowsiness. When that happens a lot, my cycling tends to worsen.

They recommended looking into developing it as a possible antidepressant. The 5-HT downregulation is common with many antidepressants-I think they were primarily looking at the anxiolytic effects. Nortripytline (the parent compound) *is* active. NT just happens to be the only tricyclic that I have had any success with. Amitriptyline is it's parent. Another study was done where they gave AMI to a group of people and measured the relative balance of AMI and NT in their blood. The people that had the highest remission rates had the highest NT blood levels. How active E-10 OH-NT compared to *it's* parent we probably will never know.

PharmRep,
Yes, I heard about that. I was on Celexa with other meds for a couple of years. Next pdoc appt. is next week though, so no likelihood of any samples available just yet. I am willing to give it a trial. I will be looking at how it differs from Celexa as far as GI problems go (reflux, heartburn, diarrhea). Celexa has been the worst med I have ever taken for reflux trouble (except for a couple of NSAIDS). I am especially sensitive to SSRI's for GI troubles. OTOH, I only ever needed about 2-5mg of Celexa/day (and not much of any other antidepressant for that matter), so I am looking at a trial of 1-2mg of Lexapro every day.

gi issues with celexa were mostly in first 8 wks (ie...nausea for cx=21%/placebo 14%) and seemed to drop to placebo-like in long term studies (6-24 mo's...ie nausea..cx=6%/placebo=10%) Of course everyone responds differently, but the side effect profile is promising. Your Celexa dose sounds very low, but again, you could be ultra-sensative. I do know the 10mg pill for Lex will be scored...it sounds like you can try 5mg (or 2.5 if you like to use razors)

> johnjWeird things these mind altering drugs do. Some people respond getting tired, while others get a "lift." I can tell you this...the FDA is allowing this statement in the package insert...side effects and discontinuation due to adverse events are equal to placebo. That is huge...there is always the "placebo-effect" that kicks in when you "study" a drug. Anyway, I would think that lex will probably effect you like celexa did, but at a lesser degree, perhaps no effect, but probably not the opposite..ie..if you had insomnia, you wont now have somnolence...and yes, some s/e that occur in first few months sometimes fade away with time (ie for celexa nausea is higher than placebo at 8 wks, but less at 6 months)
