ABSTRACT
The placebo effect is both pervasive and universal phenomenon that has accompanied the practice of medicine since the beginning. For many years, the placebo has been considered like an inert substance; however, there is confusion in medicine by identifying the word placebo as an object rather than an effect. Recent research has shown that the placebo effect is a genuine psychobiological event attributable to all the therapeutic context.
In this article, we analyze the concept of “placebo effect”, its mechanisms and clinical implications, some methodological aspects of studies with placebos, the definition of equivalence studies, their methodological and analysis to this type of study.
