Brief Summary

Although stress has long been linked to substance use, craving and relapse, there are no available medications that target stress-induced substance use disorder (SUD). In particular, with the rise in opioid use, there is still a crucial need for developing effective pharmacological treatments that target and integrate the complexity of this disease. The long term goal of this project is to identify the key neuroendocrine pathways that are responsible for stress-induced craving in individuals with opioid use disorder (OUD) in order to better understand how they can be effectively treated.

Outcome Measures

Primary Outcomes (1)

  • Opioid Craving

    The primary outcome will test the effect of oxytocin, compared to placebo, on opioid craving during two laboratory stress induction, paired to a cue reactivity paradigm. The dependent measure for the primary aim is the Desire for Drug Questionnaire (DDQ). The stress induction will be done using yohimbine or matching placebo (counterbalanced) during the two laboratory sessions. At each visit the DDQ will be administered 3 times: before starting any procedure, after the yohimbine challenge, and after the cue-reactivity. This outcome will be compared between oxytocin and matching-placebo. Minimum score=0 no craving at all, maximum score= 91 severe craving (13 questions on a 7-step Likert-scale)

    Before starting any procedure, after the yohimbine challenge, and after the cue-reactivity at each laboratory session, which occurred between days 5-7 and days 14-16.

Secondary Outcomes (4)

  • Safety and Tolerability of Oxytocin and Yohimbine in OUD Individuals Receiving Opioid Agonist Therapy: Opiate Withdrawal Syndrome

    Before starting any procedure, after the yohimbine challenge, and after the cue-reactivity at each laboratory session, which occurred between days 5-7 and days 14-16.

  • Safety and Tolerability of Oxytocin and Yohimbine in OUD Individuals Receiving Opioid Agonist Therapy: Anxiety

    Before starting any procedure, after the yohimbine challenge, and after the cue-reactivity at each laboratory session, which occurred between days 5-7 and days 14-16.

  • Safety and Tolerability of Oxytocin and Yohimbine in OUD Individuals Receiving Opioid Agonist Therapy: Systolic Blood Pressure (SBP)

    Before starting any procedure, after the yohimbine challenge, and after the cue-reactivity at each laboratory session, which occurred between days 5-7 and days 14-16.

  • Safety and Tolerability of Oxytocin and Yohimbine in OUD Individuals Receiving Opioid Agonist Therapy: Heart Rate (HR)

    Before starting any procedure, after the yohimbine challenge, and after the cue-reactivity at each laboratory session, which occurred between days 5-7 and days 14-16.

Other Outcomes (1)

  • Stress-related Response in OUD Individuals Receiving Opioid Agonist Therapy: Salivary Cortisol

    Before starting any procedure, after the yohimbine challenge, and after the cue-reactivity at each laboratory session, which occurred between days 5-7 and days 14-16.

Study Arms (2)

Oxytocin first, then placebo

EXPERIMENTAL

Oxytocin was administered as 40 IU/0.12 mL nasal spray in each nostril once in the morning and once in the afternoon for 7 days. After a 2 day washout period, Placebo was administered as nasal spray in each nostril once in the morning and once in the afternoon for 7 days.

Drug: intranasal oxytocin, 40 IU, twice a day for 7 days

Matching placebo, then oxytocin

PLACEBO COMPARATOR

Placebo was administered as nasal spray in each nostril once in the morning and once in the afternoon for 7 days. After a 2 day washout period, oxytocin was administered as 40 IU/0.12 mL nasal spray in each nostril once in the morning and once in the afternoon for 7 days.

Drug: intranasal oxytocin, 40 IU, twice a day for 7 days

Limitations and Caveats

Attempting to probe and measure opioid craving in this setting. This study utilized a guided opioid visualization technique, the presence of drug paraphernalia, and an opioid-related video cue. These cues were broad, and different aspects of them may have proved significant to participants at different times. While this is a laboratory procedure limitation, it may also further support the use of OAT for craving management. The study's small sample size and balance between males/females.
