http://www.drugawareness.org/Archives/4 ... d0035.htmlInsight Magazine?s interview with Dr. Thomas Laughren, team leader for the neuropharmachological drug-products division of the FDA, shows that FDA was caught off guard when Dr. Arif Khan independently analyzed FDA?s data revealing that the new psychotropic drugs?including antidepressants (SSRIs) and antipsychotics? substantially INCREASED the rate of suicide in patients who participated in clinical trials testing the drugs? safety and efficacy between 1985-2000. (See: Clinical Psychiatry News
A recent study conducted by Arif Khan, medical director of the Northwest Clinical Research Center in Bellevue, Wash., and adjunct professor of psychiatry at Duke University School of Medicine, has revealed startling numbers of suicides committed and suicides attempted in the clinical trials for the new SSRI antidepressants ? numbers that for years had been hidden from both prescribing physicians and the public.
Kahn has examined the official clinical drug-trial data for all SSRIs approved by the Food and Drug Administration (FDA) between 1985 and 2000, in which 71,604 participants in the clinical trials were treated with antipsychotics, all SSRIs and anticonvulsants. The rate of suicides in the general public is 11 in 100,000, which means an incidence rate for those participating in the SSRI clinical trials of nearly 68 percent ? that?s 718 suicides for every 100,000. Kahn?s research further revealed that nearly 4 percent of SSRI drug-trial participants attempted suicide within the following year.
Asked what the FDA considers an acceptable number of deaths in clinical trials, Thomas Laughren, team leader for the neuropharmachological drug-products division of the FDA, tells Insight, ?Your question is not particularly pertinent because these trials are not designed to influence suicide. If you look at any one individual trial it is very unlikely you will find a suicide in the trial, and generally we don?t.?
You see, says Laughren, ?It?s only if you accumulate data across a large number of trials that you even have enough data to look at. What you do see in individual trials is that patients who get drugs improve more than patients who get placebo. That?s what we see. When you do a meta-analysis across a large number of trials and you look at the other outcomes of suicide and attempted suicide, you don?t see any particular benefit from being assigned the drug compared to placebo.?
Which, of course, is the point. And Laughren further announced that ?the drug is not approved for the treatment of suicide. They are approved for the treatment of depression. Dr. Khan?s findings and our findings suggest that these drugs that we?re studying and approving for depression don?t appear to have a benefit on the outcome of suicide. That is not to say that they don?t have a benefit in treating depression.?
The drugs don?t have a ?benefit? on the outcome of suicide, which they in fact increase dramatically, but they do have a ?benefit? for depression. How is this possible when in fact the clinical trials for SSRIs show the suicide rate increased by 68 percent?
?What this [increased suicide rate] would tell us,? says Laughren, ?is that this is a serious condition, not a trivial condition. Depression is a serious condition. If you look at individual trials there are so few suicides that you wouldn?t be able to make sense of it all. It?s only after you look across multiple development programs over a very long period of time that you have enough events that you can get this kind of analysis.?
So, does this mean that FDA should wait longer periods of time before approving such drugs? ?No,? says Laughren, ?because the data are very clearly showing that these drugs benefit patients. What this tells us is that it is very difficult to exclude patients that are suicidal. As hard as you try you really are not able to predict who is suicidal and who is not. It [the trial data] does not tell us that being in clinical trials puts you at risk of suicide. It is not surprising to see a few suicides when you look at a fairly large number of patients, many of whom are followed for months or years.?
But the data show the suicide rate is elevated 68 percent when comparing SSRI participants to those given placebo and to the general population. So the question isn?t whether being in a clinical trial puts a person at risk, but whether a particular drug puts a participant in a clinical trial at risk. Besides, what good does it do to be declared officially less depressed if it means you are 68 percent more likely to kill yourself?
Whitaker says, ?You shouldn?t be seeing four to five times the suicide rate in drug-treatment groups, especially when these drugs are supposed to prevent this. It?s terrible that the FDA approved drugs with these high suicide rates. Naturally they do expect some suicides, but the question is whether there is something the drug is doing that is increasing that rate, and here it looks like it may be. A further question that has to be asked is why it has taken 15 years to find out about this data. Why are we learning about these increased suicides in clinical trials 15 years after the drugs were approved??

http://www.drugawareness.org/Archives/3 ... d0002.htmlHere are the suicide rates. Keep in mind as you read through these that the rate of 11 out of 100,000 persons per year is the suicide rate for the population at large.
*752 per 100,000 for those treated with atypical antipsychotics?risperidone (Risperdal), olanzapine (Zyprexa), and quetiapine (Seroquel)
*718 per 100, 000 for those treated with the SSRIs ? Selective Serotonin Reuptake Inhibitors (Prozac, Zoloft, Paxil, Luvox, Celexa)
*425 per 100, 000 for those treated for ?social anxiety disorder? with nefazodone (Serzone), mirtazapine (Remeron), and bupropion (Wellbutrin/Zyban)
*136 per 100,000 for those treated for panic disorder?with benzodiazepine alprazolam (Xanax)
*105 per 100, 000 persons for those treated for obsessive-compulsive disorder with anticonvulsant valproate (Depakote).
These figures clearly speak for themselves. The massive numbers of wrongful death suits will obviously follow. At least loved ones will know why they have lost those who meant so much to them via such tragic circumstances.
Keep in mind as you read through this data that the new antipsychotics listed here are basically a combination of the older antipsychotics and the SSRIs. They too have a STRONG effect upon serotonin levels. Also the most likely reason researchers saw an even higher rate of suicide in placebo with the antipsychotics is that these patients were likely being abruptly discontinued from their older antipsychotics for the clinical trials. This abrupt withdrawal causes suicide.
