GSK Head: most drugs work in 30 to 50 per cent of people

'Do we need pharma?
The global market for pharmaceuticals in 2007 was estimated at US $712 bn. The BMJ Clinical Evidence website documents that only 13% of medical treatments examined have been demonstrated to have a beneficial effect, and the largest proportion, 47%, are of unknown effectiveness. But this story is little-told.
The benefits of some of the key earners are far from impressive:
Cancer chemotherapy ($13bn worldwide) 2% impact on 5-year survival
Statins ($30bn) 17% reduction in coronary events, but 25% muscle symptoms if the patient exercises
HAART ($10bn) 4-12 years delay in progression to AIDS in USA and Europe, but 4-12 months in sub-Saharan Africa
So the evidence is there that pharmaceuticals work in some cases—but at a price.
Do we hear the truth?
A 2008 study looked at the effect of pharmaceutical advertising on what journals publish about dietary supplements, and found a powerful influence; in journals with the most of such adverts, 67% of studies had negative (unsafe or ineffective) conclusions, while in those with the fewest adverts the figure was 4%. But negative findings are commonly hyped in the media (which costs money in PR and lobbying) and the positive ones go unheard.
Several years ago Hickey and Roberts wrote about specific ways to design a trial to show the absence of a benefit from these vitamins in heart disease (Hickey S. Roberts H. (2004) Ascorbate: The Science of Vitamin C, Lulu Press). In relation to a recent study critical of nutrients they commented: “We intended our advice to show how NOT to perform a trial of vitamin C and E in heart disease. Perhaps someone should explain that to them”.
Can we afford pharma?
The ecological effect of pharma is considerable. In the UK healthcare represents 8.4% of the GDP (twice that in the USA). That makes healthcare a major player in terms of carbon footprint, pollution and even resource depletion.
Pharmaceuticals contaminate the environment:
- via factory run-offs; a study in India in 2007 found “astronomical” amounts of antibiotics in a major river, coming from manufacturing plants
- via patients’ urine; bioactive levels of contraceptives have been found in urban water systems worldwide
- via disposal of unused medications; Associated Press estimated that as much as 250 million pounds of unused pharmaceuticals may be flushed into US sewers every year by hospitals and care homes.
Incinerators, including hospital incinerators, which are often in urban locations, release quantities of particulates, pesticides and heavy metals that have been shown to cause damage to health, increasing rates of cancer, heart disease and even autism.
What is coming next?
In 2003, GSK’s Vice President for Pharmacogenetics, Dr Allen Roses, said, “the vast majority of drugs - more than 90 per cent - only work in 30 or 50 per cent of the people……I wouldn't say that most drugs don't work. I would say that most drugs work in 30 to 50 per cent of people.”'

Stories of Corruption and Big Pharma

"The New York Times looks at three books that basically focus on the same thing – how we’ve been co-opted into believing that there is “a pill for every ill” by billion dollar drug companies, which bolster favorable opinion from leading medical authorities by greasing the wheels."
