简要总结
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.
详细描述
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.

研究组 & 干预措施
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.
干预措施: OxyCODONE 2.5 mg Oral Tablet (Drug)
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.
干预措施: Placebo Oxytocin Nasal Spray (Other)
Oral placebo + intranasal placebo
Serves as the control.
干预措施: Placebo oxyCODONE Oral Tablet (Other)
Oral placebo + intranasal placebo
Serves as the control.

结局指标
主要结局
Subject-rated abuse liability
时间窗: Up to 6 weeks
Using a Visual Analog Scale with scoring as 0=not at all, 20=possibly mild, 40=definitely mild, 60=moderately, 80=strongly, and 100=extremely, or any number in between. Testing occurs only in the context of 6 sessions due to a minimum of a one week washout period in between each session.
