Description
Inclusion/Exclusion Criteria:
- Participants in this study will be males and females between the ages of 18 and 60 years.
- Applicants must be opioid dependent based upon the Structured Clinical Interview for Diagnostic and Statistical Manual of Mental Disorders (DSM-IV) (SCID); in addition, they must have an opioid positive urine during the screening process (or have evidence of opioid withdrawal).
- They must be healthy, with no significant medical illnesses (e.g., insulin dependent diabetes), and without significant psychiatric illness (e.g., schizophrenia) besides their drug dependence.
- Females will have a pregnancy test prior to study enrollment, and if found to be pregnant will be excluded and referred to a substance abuse program for pregnant women (the Center for Addiction and Pregnancy) on the campus.
- Volunteers will also be excluded if they have pre-admission hypotension (due to the use of clonidine in the study).
- Applicants with a history of seizures (including substance-related seizures, such as alcohol withdrawal related) will be excluded.
- Alcohol and/or sedative dependence will be specific exclusionary criteria (given the small risk of seizures associated with tramadol use).
- Allergies to any of the study medications will be grounds for exclusion.

Measure Description |
Time Frame |
|---|---|---|
|
Mean Ratings on Clinical Opiate Withdrawal Scale (COWS) Measure of Withdrawal During Double-blind Taper (7-days) and Post-taper (7-days) Period.
Time Frame: 14 days total
|
Outcomes represent mean peak withdrawal as rated on the Clinical Opiate Withdrawal Scale (COWS) total score.
Withdrawal was collected 7 times daily and daily peak values were identified for each participant and averaged together as a function of group.
Primary outcomes were mean peak results from the 7-day taper period and first 7 days post-taper.
The COWS is an 11-item observer-rated measure of opioid withdrawal severity.
Items are rated on individual Likert scales and the total score range is 0-47.
Higher values indicate more severe withdrawal.
