研究概览
简要总结
The purpose of this study is to evaluate whether medications used in peri-procedural clinical settings can modulate drug liking.
详细描述
Specifically, we aim to measure differences in drug liking with a VAS (0 - 100) questionnaire. Additionally, we will monitor neural activity recording a frontal electroencephalogram (EEG) to detect changes in brain signals associated with opioid drug effects. By comparing behavioral and neurophysiological data across treatment and control groups, this study seeks to explore the therapeutic potential of this medication.

结局指标
主要结局
Change in Drug Liking Rating
时间窗: One minute before and 1, 3, and 5 minutes after fentanyl administration
Change in drug liking rating (0-100), anchored by divert "not at all=0" and "as much as possible=100".
次要结局
