Study Debunks Use of Anti-depressants

As Reported on MSNBC

Four popular antidepressants being used to treat thousands of depressed American children are unsafe, ineffective or both, according to the first careful scientific review to include all available studies, including negative data that have long been withheld from public scrutiny by the pharmaceutical industry.

It is especially dangerous to prescribe Paxil, Zoloft, Effexor and Celexa for children who are suicidal, said British researchers who conducted the analysis published yesterday in the journal the Lancet, because the data show a clear increase in the risk of suicidal behavior among children taking the drugs -- and no benefit.

The study calls into question the repeated assurances of the American psychiatric establishment, which has regularly encouraged use of the medications in depressed children. It also contrasts sharply with the position of the U.S. Food and Drug Administration, which has had access to the same data but has never identified such serious problems.

The analysis involved no new data, but it is the first scientific "meta-analysis" of all available trials to be published in a peer-reviewed journal. As such, it puts the scientific debate over the medications on a new footing and deepens the chasm between the predominantly positive American view of the drugs and a growing stream of negative reviews by Australian, Canadian and British psychiatrists. The Lancet analysis backs up the warning by British regulators last year not to prescribe the medications to depressed children.

In a sharply worded editorial, the Lancet's editors said the trust of patients had been abused by doctors and the pharmaceutical industry, and that safety had been compromised in the search for profits. The state of the research, the editorial concluded, is riddled with "confusion, manipulation and institutional failure."

"If I wanted to introduce a new drug for children who are suicidal and said this has very little proof of efficacy and it has an increased risk of suicide, people would say I was mad," said Tim Kendall, director of the National Collaborating Centre for Mental Health in London, and one of the authors of the new study.

Yet, Kendall said, that is precisely the situation with the four drugs. Kendall's analysis, which was funded by the British government, contrasted the largely positive results of studies published by drug manufacturers with negative data that the companies call proprietary and have not published. British regulators recently made the unpublished data available for study.
