Abstract
Methylphenidate, the main substance used in the pharmacological treatment of Attention Deficit Hyperactivity Disorder (ADHD), is currently the most consumed psychostimulant in the world and a constant matter in media and scientific production in psychology and psychiatry studies. In this article, we discuss some scientific discourse elements about this medicine by using historical elements that are rich in controversies, in order to propose their emergence as a problem, as Foucault indicates. Thus, we have analysed the diversity of meanings and practices involving this issue, from the production of the first amphetamines in laboratory in the early twentieth century to the present days, in which methylphenidate is recognized as the first choice of treatment for ADHD, reaching extremely high consumption rates around the planet. Finally, some relevant questions about the Brazilian context are pointed out, especially concerning public health policies.
