The Potential of Oxytocin to Reduce Opioid Abuse Liability and Pain Among Older Adults

Purpose

Some research suggests that administration of oxytocin with oxycodone may reduce its abuse liability and improve its ability to reduce pain. In a 6-session laboratory study, we will be evaluating the effects of oxycodone and oxytocin (combined and separately, across sessions) on experimentally-induced pain, subjective effects, and decision-making.

Inclusion Criteria

  • Individuals fluent in English will participate. - Must report some experience with opioids (e.g., oxycodone, defined as use at least once in the subject's lifetime). - Be within 20% of their ideal body weight. - Are not currently experiencing chronic pain (pain on most days during the past 3 months) - Have a systolic blood pressure of <=140 and diastolic blood pressure of <= 90, and a heart rate <= 90 beats per minute. - Participants must also have a normal electrocardiogram (EKG) reading and bloodwork indicating no major health contraindications.

Exclusion Criteria

Arm Groups

ArmDescriptionAssigned Intervention
Active Comparator
Oral oxycodone (5mg) + intranasal oxytocin (48 IU)
Combined effects of oxycodone and oxytocin.
  • Drug: OxyCODONE 5 mg Oral Tablet
    Oxycodone 5mg oral administration
  • Drug: Oxytocin Nasal Spray (48 IU)
    Intranasal oxytocin administration (48 IU)
Active Comparator
Oral oxycodone (2.5mg) + intranasal oxytocin (48 IU)
Combined effects of oxycodone and oxytocin.
  • Drug: OxyCODONE 2.5 mg Oral Tablet
    Oxycodone 2.5mg oral administration
  • Drug: Oxytocin Nasal Spray (48 IU)
    Intranasal oxytocin administration (48 IU)
Active Comparator
Oral placebo + intranasal oxytocin (48 IU)
Separate effects of oxytocin. As is standard methodology in abuse liability and pain assessments, a placebo condition will be included for each drug in order to compare the abuse liability and pain assessments change from placebo.
  • Other: Placebo oxyCODONE Oral Tablet
    Oxycodone 0mg (placebo) oral administration
  • Drug: Oxytocin Nasal Spray (48 IU)
    Intranasal oxytocin administration (48 IU)
Active Comparator
Oral oxycodone (5mg) + intranasal placebo
Separate effects of oxycodone. As is standard methodology in abuse liability and pain assessments, a placebo condition will be included for each drug in order to compare the abuse liability and pain assessments change from placebo.
  • Drug: OxyCODONE 5 mg Oral Tablet
    Oxycodone 5mg oral administration
  • Other: Placebo Oxytocin Nasal Spray
    Intranasal oxytocin placebo administration
Active Comparator
Oral oxycodone (2.5mg) + intranasal placebo
Separate effects of oxycodone. As is standard methodology in abuse liability and pain assessments, a placebo condition will be included for each drug in order to compare the abuse liability and pain assessments change from placebo.
  • Drug: OxyCODONE 2.5 mg Oral Tablet
    Oxycodone 2.5mg oral administration
  • Other: Placebo Oxytocin Nasal Spray
    Intranasal oxytocin placebo administration
Sham Comparator
Oral placebo + intranasal placebo
Serves as the control.
  • Other: Placebo oxyCODONE Oral Tablet
    Oxycodone 0mg (placebo) oral administration
  • Other: Placebo Oxytocin Nasal Spray
    Intranasal oxytocin placebo administration

Detailed Description

The overall project goals are to determine oxytocin effects on oxycodone's subject-rated abuse liability, and experimental pain. Generally healthy individuals (determined via medical history review and a screening session) will, after informed consent, self-administer intranasal oxytocin (or placebo, containing the same ingredients but no oxytocin) shortly after oral oxycodone or placebo in a non-residential, double-blind, randomized, placebo-controlled, within-subjects laboratory study. Prescreening will assure drug application safety and, using a validated, comprehensive pain history interview, determine previous or existing chronic pain conditions, including current pain medication use.
