It would be reassuring to be able to assume that when your Doctor prescribes a drug, it's because he thinks it is the best one for your condition, guaranteed to help you get better.  But that is only a dream of the ideal.  In actual fact, quote:

In the world of medicine, "key opinion leader" is the somewhat Orwellian term used to describe the senior doctors who help drug companies sell drugs.

Read the report in the British Medical Journal, and listen to the revealing video of a former drug rep plumbing the depth of this disgraceful shill.  These influential Doctors are PAID to represent to their peers that recent medications are effective and safe - when all they may be is new and unproven.

Key opinion leaders: independent experts or drug representatives in disguise?
