Placebos Are Getting More Effective 349

Wired is reporting that the well-known "placebo effect" seems to be increasing as time goes on. Fewer and fewer medications are actually making it past drug trials since they are unable to show benefits above and beyond a placebo. "It's not only trials of new drugs that are crossing the futility boundary. Some products that have been on the market for decades, like Prozac, are faltering in more recent follow-up tests. In many cases, these are the compounds that, in the late '90s, made Big Pharma more profitable than Big Oil. But if these same drugs were vetted now, the FDA might not approve some of them. Two comprehensive analyses of antidepressant trials have uncovered a dramatic increase in placebo response since the 1980s. One estimated that the so-called effect size (a measure of statistical significance) in placebo groups had nearly doubled over that time."

        The GP's article suggested another reason:

        He goes on to talk about how placebo has become a crisis of the industry, but I have another explanation: it's not "placebo" that's the problem. If drugs in testing cannot outperform placebo, then the researches have done a good job of testing the drugs honestly. If the researchers are failing to develop drugs that beat placebo and the company's bottom line is suffering, it's not the fault of the sugar pill. Sometimes it's either difficult or impossible to develop an effective medication. Failure is inevitable. It's how science works. If the CEOs don't like it, they have to either make up the data, or find a new business model.

        It's not anything to do with the placebo, it's that the drugs that are being developed currently don't do anything.

          That sill doesn't explain why placebos are now nearly twice as effective as ~1990, but this paragraph from the article might be a factor:

          Potential trial volunteers in the US have been deluged with ads for prescription medications since 1997, when the FDA amended its policy on direct-to-consumer advertising. The secret of running an effective campaign, Saatchi & Saatchi's Jim Joseph told a trade journal last year, is associating a particular brand-name medication with other aspects of life that promote peace of mind: "Is it time with your children? Is it a good book curled up on the couch? Is it your favorite television show? Is it a little purple pill that helps you get rid of acid reflux?" By evoking such uplifting associations, researchers say, the ads set up the kind of expectations that induce a formidable placebo response.

          The frequent ads from the companies are effectively brain-washing Americans to think, "All you need is a little purple pill to feel good," and so the mere act of swallowing that pill, even if it's just sugar, becomes twice as effective as previously.

              The great thing about this, in a properly controlled double blind test is that it doesn't matter. The real pill gets the same psychological boost as the placebo. Both pills have the same base line. Now the difference between the two pills is due to the differences in the active ingredients.

      It's not unthinkable that placebos could be having a more pronounced results than they have in the past. In the Prozac example, psychiatry related drugs are especially prone to placebo effects. Given that the average citizen knows a lot more about these drugs than they did 10+ years ago due to ads and the media, they're more likely to believe it'll work for them than people used to.

      No, the guy who wrote that article is wrong. He is using "placebo" where he should be saying "control". A control is what you use to measure the difference between normality and the thing you are testing. In medicine, this may or may not involve a placebo (which means a "pleaser"). For example, I can give 1000 people my new drug, and put another 1000 people in a control group, with no drug. However, I may worry that some of the improvement in my patients is due to the psychological effect of popping a pill; I therefore may give the control group a fake pill to take, called a placebo. If I have enough funding, I may even have three groups: one with the real drug, one control group with the placebo, and one true control group with absolutely nothing. This will often produce three levels of improvement.

      A control cannot be described as strong or weak, but a placebo given as part of a control certainly can be. Although it is something designed to have no real effect, the fact is that every aspect of the treatment situation (the colour of the pills, frequency of treatment, the crispness of the white coats...) alters the strength of the pleasing effect, which can have major consequences for health and well-being.

    People are more and more diagnosed with depression. A high placebo effect in treating depression is, in my uneducated opinion, at least partially indicative of over-diagnosis. While in the past only the truly sick were diagnosed as depressed, today perhaps some of the patients aren't really that depressed, and thus can be treated with placebo/happy thoughts. To what degree is depression caused by "wrong" behavioral and mental patterns, and to what degree is it born of a chemical imbalance? Of course, they may cause each other, but I do believe that some depression cases are not that deep-seated. If it's a deep, recurring or continuous depression, then use real drugs that changes brain chemistry and how the brain functions. If it's not that bad, a pep talk and placebo just might push the brain towards solving it's own imbalances.

    A lot of people -- like the author of Talking Back to Prozac [psychologytoday.com] -- claim that some drug trials (especially for popular antidepressants) are compromised to the point that getting drugs like Prozac approved required requires a surprising amount of massaging of the data from drug trials just to get to the point where the drug seems to perform better than placebo. This New Scientist article from last year about how antidepressants' effects may have been exaggerated [newscientist.com], has a good definition of a particular form of publication bias [wikipedia.org] that is apparently common:

    It's called the "file-drawer problem". A study fails to produce interesting results, so is filed away and forgotten - a practice that might mean antidepressants don't work as well as doctors think.

    If that's true, then it's a gambit that would get less and less effective over time. Certainly, drug companies have a very large commercial interest in boosting the apparent effectiveness of their drugs by "enhancing" the results of their trials through selectively ignoring results they don't like. It does sound somewhat conspiracy theory-ish, but it seems like there's increasing evidence. Plus, if it's true that antidepressants are less effective than many doctors believed in the past, that's more evidence that the trials drew incorrect conclusions.

  • For me is that the original tests were "helped" to better numbers, as they meant billions of dollars in profits. Now the interest is not so big and so the numbers are closer to reality.

    Placebo also has the most side effects of any drug on record.
  • Why would this be surprizing? The scientific method and the belief that your beliefs need to be examined and their truth verified are recent inventions. For most of human history the vast majority always believed what they were told. As rationality is dying out, due to schooling and various other factors, so is skepticism and science. As time goes on, we can all expect people to increase blind faith and achieve whatever natural healing their bodies can provide.

    turns out that the placebo effect is hugely influenced by beliefs. So - if people are in a trial to treat mental illness, then the placebo will be more effective now than it was 20 years ago simply because people on average believe that mental illnesses are treatable.

    In a similar vein, Cimetidine (one of the first ulcer drugs) has become much less effective over time. It suffered a dramatic drop in success rate when the new ulcer drug Ranitidine came on to the market. It seems that as doctors stopped thinking of it as the best drug, it became less effective.

    No big surprise that placebos are working better in some contexts. It doesn't show that the placebo effect is generally getting stronger though.

      The placebo effect is entirely caused by belief.

    Note that the only actual evidence for a more robust placebo effect referred to in the article is two studies looking at antidepressants. There are also a couple of anecdotes (from companies looking for a scapegoat for their failure) about Parkinson's and Crohn's, but that's hardly evidence.

    It would be interesting if there was data for conditions that can be assessed objectively.

    The article needed to be about two paragraphs and could certainly have stood to lose all the gushing about how powerful and neglected the placebo effect is. On the bright side, I see Wired is hiring people with no photography or design experience to generate their figures.

    Are more people than ever getting over diagnosed, or is the power of thought becoming more powerful?

  • I have suffered from chronic back pain for 25+ years. I was recently given a 'sample' drug by my doctor to determine if it was helpful.

    The first dose was about 75% effective. It eliminated some of the pain but not all. The subsequent dosages (which included increasing the # of pills) had ZERO effect on pain levels. I do not doubt that placebo effect accounted for the initial pain relief, but I am usually very logical and calm about drug actions on my psyche.
       

  • That is, if you are measuring drugs effectiveness to cure Measels, then a placebo will not be very effective.

    But if you are measuring a drug's effect to cure something like say Restless Leg Syndrome, then surprise surprise the placebos work WONDERS.

    When you have idiots defining healthy active children as suffering from attention deficit disorder, surprise surprise, a sugar pill (yeah, irony) works to cure them.

    This particular case, the disease was depression. Depression is a real disease, but it is exa

  • This is all very well but it comes from research involving Big Pharma products - bought and paid for!!! To test these new placebos we need some kind of control. Like, some kind of substance that has no effect on the patients so that we can use it to gauge the placebos agains......

    If anything the diagnostic criteria for some illness have been loosened, if not in print then in practice (depression, ADD, Bipolar, various allergies). Some "ailments" weren't really considered that big of a deal 20-30 years ago, or were at least considered rare (Restless Leg Syndrome, Premenstrual dysphoric disorder, fibromyalgia). Perhaps, and I say this more to be devil's advocate, we are treating people with symptoms, or not, of diseases that they don't have, or don't really exists in the manner we think they exist. At least in terms of treatment. As such, the treatment is wrong (either by lack of disease or bad targeting), and of course would be expected to be no better than placebo.
