Rational use of medicines, pharmaceuticalization and uses of methylphenidate.

The rational use of medicines (URM) is considered one of the key elements recommended by the World Health Organization (WHO) for pharmaceutical policies. The excessive increase in the use of medicines in many countries has been identified as a major barrier to the achievement of URM and is part of a phenomenon called the 'pharmaceuticalization' of the society. This paper aims to present innitiatives to rationalize the use of methylphenidate and its limits in Brazil, considering the concept of pharmaceuticalization of the society. It is an exploratory study, based on a narrative review of the scientific literature. Controversies about the uses of methylphenidate make it a good example of this phenomenon and may help in the reflection and construction of new paths to the limits found by the concept of rational use of medicines.
