IT'S ALL IN YOUR MIND...BUT WE CAN MAKE YOUR MIND STRONGER:

IN PAINKILLER TRIALS, PLACEBO EFFECT IS BECOMING MORE POWERFUL (Alexandra Ossola, 10/07/15, Popular Science)

Painkiller manufacturers are confused. Their drugs have maintained the same efficacy at relieving symptoms for the past 25 years, but the placebo effect has gotten stronger in drug trials conducted in the U.S., according to an analysis of 35 experiments published online ahead of print in the journal Pain. In 1996, a painkiller relieved symptoms in 27 percent more patients than a placebo; in a similar trial in 2013, it was only 9 percent, as Nature News reports. As a result, the drugs are appearing less effective during clinical trials, which means that fewer of them have been approved by the Food and Drug Administration; over the past 10 years, more than 90 percent of drugs designed to treat pain have failed in late stages of testing.
