This article may help explain addiction science through research on opioid, cocaine, brain science, withdrawal. The source abstract begins by describing: “Persistent vulnerability to drug-seeking is driven by enduring synaptic adaptations, yet current μ-opioid receptor-targeting pharmacotherapies provide limited efficacy against these neuroadaptations.”
Key finding: By targeting a pathway independent of classical opioid receptor signaling, CA4 inhibition represents a mechanistically distinct strategy that may reduce relapse vulnerability in OUD.

This article may help explain addiction science through research on opioid, brain science, withdrawal, relapse. The source abstract begins by describing: “Opioid use disorder (OUD) is a chronic relapsing disorder that is a major burden for the lives of affected individuals, and society as a whole.”
Key finding: Altogether, these animal models will contribute to study behavioural and neuronal circuitries involved in the several negative affective signs characterizing OUD.

This article may help explain addiction science through research on opioid, alcohol, dopamine, brain science. The source abstract begins by describing: “Opioid-alcohol polysubstance use is prevalent and worsens treatment outcomes.”
Key finding: Thus, alcohol alters the motivation to seek oxycodone in a sex-dependent manner and the neural circuitry engaged by cue-primed reinstatement of sucrose and oxycodone-seeking.

This article may help explain addiction science through research on opioid, cocaine, methamphetamine, relapse. The source abstract begins by describing: “Social reinforcement-based treatments are effective for many, but not all, people with addictions to drugs.”
Key finding: This choice procedure can identify mechanisms of individual differences in an animal model of cocaine use and could thereby help screen medications for people who are relatively unresponsive to treatments based on rewarding social interaction.

This article may help explain addiction science through research on opioid, withdrawal, craving, relapse. The source abstract begins by describing: “Existing pharmacological treatment options for opioid use disorder (OUD) face challenges that limit their efficacy.”
Key finding: This review adopts a translational approach to achieve several aims: (1) to outline the fundamental theories of orexin system function and relate orexinergic dysfunction to the disordered motivation and withdrawal states that characterize OUD; (2) to provide an up-to-date evaluation of preclinical and clinical evidence bases supporting the efficacy of orexin receptor antagonism for the treatment of OUD; (3) to discuss key clinical considerations of repurposing DORAs for OUD treatment, including safety and side effects (i.e., respiratory depression, anhedonia, and risk for abuse); and (4) to highlight the ongoing clinical efforts to determine therapeutic efficacy and safety profiles of DORAs for use in OUD populations.
