Developing Treatments for Stimulant Abuse: A Brief Overview

Abstract

The abuse of stimulants such as cocaine, amphetamine, and methamphetamine is a huge problem in many parts of the world. Abuse of these drugs does not ruin just the user's life, but also adversely affects those around them. Despite many years of research, there are no approved medications for stimulant dependence, and treatment is focused on psychotherapy and abstinence. Over the last 10 to 20 years, there have been some major changes in approach to medication development for stimulant dependence. These include assessing ligands for non-dopaminergic sites, atypical dopamine transporter ligands, blocking long-term potentiation and / or memory reconsolidation, vaccines against the stimulant, and molecular approaches including pharmacogenomics and gene silencing. Also included in this overview are non-drug treatments such as deep brain stimulation and psychosurgery. This overview highlights recent preclinical and clinical studies of treatment development for stimulant dependence.
