Primary Outcome Measures:
  • assessment of opioid withdrawal symptoms [ Time Frame: 45 days ]
    During their treatment, patients are closely monitored by a multidisciplinary team, and there are regular assessments of pain, depression, substance use, and pain-related physical and emotional functioning

  • Assessment of cravings at one month following opioid tapering [ Time Frame: 45 days ]
    During their treatment, patients are closely monitored by a multidisciplinary team, and there are regular assessments of pain, depression, substance use, and pain-related physical and emotional functioning


Enrollment: 21
Study Start Date: June 2011
Study Completion Date: December 2012
Primary Completion Date: September 2012 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: Varenicline
We will be comparing Varenicline to placebo in a single-blinded placebo controlled, randomized study
Drug: Varenicline
Patients will be randomly assigned to receive either varenicline or placebo for 45 days. Patients assigned to varenicline and are current smokers will receive 0.5mg by the oral route once a day for 3 days, followed by 0.5mg twice a day for 4 days. After the first week the dose will be increased to 1mg twice daily for the remainder of the active treatment period of the study. Patients assigned to varenicline and are non-smokers will receive 0.5mg by the oral route once a day for 6 days, followed by 0.5mg twice a day for 6 days. After the first 12 days the dose will be increased to 1mg twice daily for the remainder of the active treatment period of the study. Patients assigned to placebo will receive identical looking capsules in a dosage schedule similar to varenicline.
Other Name: Chantix
Placebo Comparator: Placebo
We will be using a placebo in a randomized, controlled, single-blinded trial to look at varenicline for the indication of facilitating opioid tapering in opioid-dependent patients with chronic pain.
Drug: Placebo
Patients will be randomly assigned to receive either varenicline or placebo for 45 days. Patients assigned to varenicline and are current smokers will receive 0.5mg by the oral route once a day for 3 days, followed by 0.5mg twice a day for 4 days. After the first week the dose will be increased to 1mg twice daily for the remainder of the active treatment period of the study. Patients assigned to varenicline and are non-smokers will receive 0.5mg by the oral route once a day for 6 days, followed by 0.5mg twice a day for 6 days. After the first 12 days the dose will be increased to 1mg twice daily for the remainder of the active treatment period of the study. Patients assigned to placebo will receive identical looking capsules in a dosage schedule similar to varenicline.
