Antidepressant Drugs Don't Work – Official Study

They are among the biggest-selling drugs of all time, the "happiness pills" that supposedly lift the moods of those who suffer depression and are taken by millions of people in the UK every year.

But one of the largest studies of modern antidepressant drugs has found that they have no clinically significant effect. In other words, they don't work.

The finding will send shock waves through the medical profession and patients and raises serious questions about the regulation of the multinational pharmaceutical industry, which was accused yesterday of withholding data on the drugs.

In the study, researchers conducted a meta-analysis of all 47 clinical trials, published and unpublished, submitted to the Food and Drug Administration in the US, made in support of licensing applications for six of the best known antidepressant drugs, including Prozac, Seroxat – which is made by GlaxoSmithKline – and Efexor made by Wyeth. The results showed the drugs were effective only in a very small group of the most extremely depressed.

Two drugs were excluded from the study because of incomplete data. A third drug, chemical name nafazodone, has been withdrawn from the market because of side-effects.

Professor Irving Kirsch of the University of Hull, who led the study published in the online journal Public Library of Science (PLoS) Medicine , said the data submitted to the FDA would also have been submitted to the licensing authorities in Britain and Europe. It showed the drugs produced a "very small" improvement compared with placebo of two points on the 51-point Hamilton depression scale.

That was sufficient to grant the drugs a licence but did not meet the minimum three-point difference required by the National Institute for Clinical Excellence (Nice) to establish "clinical" significance. Full-monty available here - in tomorrow's UK Independent.

These drugs are just meant to temporarily make you happy in episodes of anxiety and depression. They don't actually cure  and targets the cause. Mind control is the key to combat and neutralize depression. Antidepressants just acts as "pain relievers", so people diagnosed with depression should also develop ab active lifestyle and a supportive family should be there for them.
