Diethylpropion and mazindol: An end to the discussion?

Rev Assoc Med Bras (1992). 2017 Mar;63(3):203-206. doi: 10.1590/1806-9282.63.03.203.


Antiobesity pharmacotherapy remains the main point of disagreement among both scientists and regulators. This is probably due to small sample sizes, high levels of heterogeneity, and low methodological quality. For many years, Brazil was one of the largest consumers of appetite suppressants worldwide, with evidence of irrational use of this drug class. Therefore, the country was the scene of a debate that divided the Brazilian Health Surveillance Agency (Anvisa - Agência Nacional de Vigilância Sanitária) and medical societies over the maintenance record of diethylpropion, mazindol and fenproporex. In this context, this commentary presents new arguments to contribute to the discussion, as well as recommendations for future studies.
