Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

This research is being done to evaluate whether suvorexant may reduce the use of, subjective liking, and demand for various drugs.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

This research is being done to evaluate whether suvorexant may reduce the use of, subjective liking, and demand for various drugs. Suvorexant is not approved as a treatment to reduce drug use but is approved by the Food and Drug Administration (FDA) to treat insomnia (trouble falling asleep or staying asleep). This study consists of a screening visit and an approximate 14 to 16 day inpatient (overnight) stay at the Johns Hopkins Bayview Medical Center. Participants will be stabilized on hydromorphone, randomly assigned to receive either suvorexant or placebo, and complete 5 experimental sessions that include taking blinded study medications.

Drug B (Blinded Drug)

Intervention Type DRUG

Participants will receive a double-blinded oral study medication as part of their daily sessions and will provide feedback regarding the effects of the medication on various measures. Though the study medications are FDA approved, they are being used here for a non-FDA approved purpose (though the FDA has provided permission to use these drugs in this study).

Drug C (Blinded Drug)

Intervention Type DRUG

Participants will receive a double-blinded oral study medication as part of their daily sessions and will provide feedback regarding the effects of the medication on various measures. Though the study medications are FDA approved, they are being used here for a non-FDA approved purpose (though the FDA has provided permission to use these drugs in this study).

Drug D (Blinded Drug)

Intervention Type DRUG

Participants will receive a double-blinded oral study medication as part of their daily sessions and will provide feedback regarding the effects of the medication on various measures. Though the study medications are FDA approved, they are being used here for a non-FDA approved purpose (though the FDA has provided permission to use these drugs in this study).

Suvorexant (20mg/day)

Intervention Type DRUG

Double blind administration of suvorexant once per day during residential stay until discharge.
