MPs and campaigners predict class action after failures to mount full-scale research into warnings left millions of patients at risk
Secret documents reveal that government-funded experts were warned nearly 30 years ago that tranquillisers that were later prescribed to millions of people could cause brain damage.
The Medical Research
Council (MRC) agreed in 1982 that there should be large-scale studies to examine the long-term impact of benzodiazepines after research by a leading psychiatrist showed brain shrinkage in some patients similar to the effects of long-term alcohol abuse.
However, no such work was ever carried out into the effects of drugs such as Valium, Mogadon and Librium – and doctors went on prescribing them to patients for anxiety, stress, insomnia and muscle spasms.
