Claritin advertisements cause a placebo effect

It is well known that beliefs about the quality of a drug can enhance its physiological effect, but little is known of the impact of advertising of a branded drug. Kamenica et al (PNAS August 2013) conducted a clinical trial to measure the physiological impact of direct-to-consumer advertising of the antihistamine Claritin. The authors exposed subjects with or without allergies to a skin test of common allergens, and then subjects received Claritin, and viewed advertisements for Claritin or Zyrtec.  Regardless of allergy, all subjects experienced a wheal reaction to the skin test. In the allergy subpopulation, there was no significant change in beliefs associated with exposure to Claritin advertisements; however, in the subpopulation without allergies, exposure to Claritin advertisements increased the efficacy of Claritin (16% at 120 minutes).  This result suggests that advertising can have strong psychologically mediated physiological effects to a drug. 

It is unclear if the results were due to the positive effect of Claritin ads or a negative effect of Zyrtec ads.  A small pilot test included a group that did not receive advertisements, but the authors did not replicate this arm in the larger study.  A follow –up trial should be conducted to determine if positive or negative advertisements have a greater effect as well as a no advertisement control group.

  2. I am bold enough among many others to state that there is now a potent cure to this sickness but many are unaware of it. I discovered that I was infected with the virus 3 months ago, after a medical check-up. My doctor told me and I was shocked, confused and felt like my world has crumbled. I was dying slowly due to the announcement of my medical practitioner but he assured me that I could leave a normal life if I took my medications (as there was no medically known cure to Herpes). I went from churches to churches but soon found that my case needed urgent attention as I was growing lean due to fear of dying anytime soon. In a bid to look for a lasting solution to my predicament, I sought for solutions from the herbal world. I went online and searched for every powerful trado-medical practitioner that I could severe, cos I heard that the African Herbs had a cure to the Herpes syndrome. It was after a little time searching the web that I came across one Dr Itua(A powerful African Herbal Doctor), who offered to help me at a monetary fee.
