A mindfulness-based intervention for Substance Use Disorder in a Brazilian vulnerable population: a feasibility mixed method study.

Front Public Health

November 2024

Núcleo de Pesquisa em Saúde e Uso de Substâncias, Departamento de Psicobiologia, Universidade Federal de São Paulo, São Paulo, Brazil.

Introduction: Substance Use Disorder (SUD) is a chronic condition that impacts various facets of an individual's life, and society as a whole. The Mindfulness-Based Relapse Prevention (MBRP) protocol is an innovative intervention that can help to prevent relapse, particularly when used as a post-treatment approach. However, although there is significant evidence of its effectiveness in studies from high-income countries (HICs), there is a dearth of studies examining its feasibility and efficacy in low- and middle-income countries (LMICs).

The development of HS-donating derivatives of non-steroidal anti-inflammatory drugs (NSAIDs) is considered important to reduce or overcome their gastrointestinal side effects. Sulforaphane, one of the most extensively studied isothiocyanates (ITCs), effectively releases HS at a slow rate. Thus, we rationally designed, synthesized, and characterized new ITC derivatives (I1-3 and I1a-e) inspired by the natural compound sulforaphane.
