Issued by

National Institute on Drug Abuse (NIDA)

Purpose

The National Institute on Drug Abuse is issuing this Notice to highlight its interest in preclinical and clinical research to advance the understanding of the effects of concomitant use of opioids and stimulants. The use of opioids, such as heroin and fentanyl, together with stimulants, such as methamphetamine and cocaine, is increasing; and deaths attributed to using these combinations are likewise increasing (Al-Tayyib et al., 2017; Jones et al, 2019; LaRue et al., 2019). Opioid overdose causes asphyxiation due to respiratory depression and stimulant overdose causes agitation, hyperthermia, and cardiac events due to sympathetic stimulation; however, the effects of their concomitant use have not been adequately characterized. Treatment of overdose of opioid-stimulant combinations is currently based on symptoms. Studies in animals and cell culture have demonstrated that exposure to an opioid and methamphetamine together can be more toxic than either drug alone (Namiki et al., 2005; Tian et al., 2017). However, the mechanisms underlying the potentially enhanced toxicity of the combination remain unknown. Identifying how opioids and stimulants interact in combination to produce increased toxicity will enhance our ability to develop medications to prevent and treat comorbid opioid and stimulant use disorders and overdoses associatedwith this combination of drugs.

Research Objectives

  • To support mechanism-based approaches that will 1) elucidate factors and mechanisms mediating the toxic effects of concomitant opioid and stimulant use and 2) point to new therapeutic targets and prevention strategies.

Areas of programmatic interest to NIDA include, but are not limited to:

  • Identifying and understanding the medical safety risks of concomitant opioid and stimulant use
  • Identifying mechanisms that underly increased or unique toxic effects of concomitant opioid and stimulant use including, but not limited to, molecular pathways, neurotransmitter actions, peripheral pathophysiological processes, and central-peripheral neural network interactions
  • Identifying organ- or physiological system-specific vulnerabilities to concomitant opioid-stimulant exposure and use
  • Understanding how concomitant opioid and stimulant use affect homeostasis of physiological systems (cardiovascular and respiratory)
  • Understanding how concomitant opioid and stimulant use affect each other’s pharmacodynamics and pharmacokinetics
  • Identifying risk factors (e.g., genetic polymorphisms) that may predispose certain individuals to be more susceptible to toxic effects of concomitant opioid and stimulant use
  • Identifying potential physiological markers of toxicity due to opioid-stimulant interactions that could be used to diagnose and manage patients more effectively
  • Developing treatments for overdose due to concomitant opioid and stimulant use
  • Development of treatments for comorbid Opioid and Stimulant Use Disorders
