Active clinical trials for "Opioid-Related Disorders"

The purpose of this study is to conduct experiments to examine subjective and reinforcing effects of nitrous oxide. Mood altering and psychomotor effects will be tested on non-drug abusers and preference procedures will be used to assess reinforcing effects. To evaluate: cold water immersion modulates the reinforcing effects of nitrous oxide in healthy volunteers.

The purpose of this study is to conduct experiments to examine subjective and reinforcing effects of nitrous oxide. Mood altering and psychomotor effects will be tested on non-drug abusers and preference procedures will be used to assess reinforcing effects. To examine the lack of acute tolerance development to the subjective, cognitive, and psychomotor effects of nitrous oxide in healthy volunteers.

The purpose of this study is to conduct experiments to examine subjective and reinforcing effects of nitrous oxide. Mood altering and psychomotor effects will be tested on non-drug abusers and preference procedures will be used to assess reinforcing effects. To test the hypothesis that isoflurane at subanesthetic concentrations does not reduce cold-water immersion pain in healthy volunteers.

The purpose of this study is to detect increasing medication dose results in heroin cessation for patients still using, to determine if decreasing medication dose in patients unable to tolerate medication dose increases retention, and to determine if blood levels of methadone or buprenorphine correlate with clinical response.

The goal of this experimental study is to compare different education intervention on opioid education for patients undergoing total knee arthroplasty. The specific research questions to address are: Does perioperative education pathway reduce opioid refill requests? Is education pathway that focuses on pain management provided in-person and via video in repeated sessions more effective than current standard of care education consisting of a single exposure given as part of a broader preoperative presentation covering multiple topics? Is there a difference between education provided in-person vs video? Does perioperative education improve compliance with multimodal analgesia? Does perioperative education improve appropriate opioid storage? Does perioperative education improve appropriate opioid disposal? Enrolled patients will be assigned at random to one of 3 study groups. Group 1 (control): Patients are referred to the hospital's standard 1-hour virtual patient education webinar prior to surgery. Group 2 (in-person): Patients will receive two in-person education sessions (1st session before surgery and 2nd session after surgery). Patients will also receive portable document format (pdf) handouts about opioid and pain management. Group 3 (video): Patients will receive two video education sessions (1st session before surgery and 2nd session after surgery). Patients will also receive pdf handouts about opioid and pain management.

A pre-post, single-group, quasi-experimental design will be used to determine the acceptability, feasibility, and appropriateness of a theory-based, 8-week/16-session virtual Tai Chi Easy (vTCE) intervention for adults with OUD, anxiety, and chronic pain. This dissertation has three Aims: 1) Determine the feasibility of an 8-week/16-session, vTCE intervention for adults with OUD, CP, and anxiety; 2) Determine the perceptions of the vTCE intervention participants by conducting a focus group interview post-vTCE; 3) Explore within-subject changes in generalized anxiety, chronic pain intensity, opioid use, opioid cravings, and basic psychological needs post-vTCE.

This is a Phase 1, single-centre, randomized, double-blind, placebo-controlled, MAD study in healthy male and female adult subjects. The study will include up to 48 subjects (12 subjects per cohort) who will be randomized 9:3 to active drug or placebo. Each cohort will receive AZD4041 or placebo in a MAD study. A sequential cohort MAD design will be employed to assure that higher doses are administered to healthy subjects only after lower doses have demonstrated an acceptable safety profile. The total study duration will be up to 59 days (including Screening) per subject.

The purpose of this open-label pilot study is to determine the tolerability and applicability of outpatient long-acting injectable naltrexone (Vivitrol) treatment in individuals age 16-25 ("older youth") with opioid use disorder. Outpatient treatment will consist of a 7-day outpatient detoxification / naltrexone induction procedure followed by 8-weeks of treatment with Vivitrol.

The aim of this study is to investigate which method of naltrexone induction during rapid opioid detoxification causes stronger stress response and has a higher influence on opioid abstinence caused by opioid induction.

The investigators will randomize 50 opioid-dependent participants who have initially failed outpatient induction onto XR-NTX; participants will receive buprenorphine/naloxone on a weekly basis for 30 days. Buprenorphine/naloxone will be dispensed weekly during the 30-day stabilization and twice weekly during taper phase, and all patients who successfully complete the detoxification will be offered induction onto XR-NTX. All participants will receive weekly therapy with a study psychiatrist. All participants will receive open-label medication. The primary outcome of this study will be percentage of patients successfully inducted onto XR-NTX. Secondary outcomes will be time to relapse, defined as opioid use or dropout.
