Brief Summary

This study proposes to compare a low-dose versus a high-dose buprenorphine induction scheme in 40 fentanyl using people with Opioid Use Disorder (OUD). Study participants will be randomized to either the low-dose (n=20) or high dose (n=20) group and dispensed medication daily for one week.

Detailed Description

This study proposes to compare a low-dose versus a high-dose buprenorphine induction scheme in 40 fentanyl using people with Opioid Use Disorder (OUD). Study participants will be randomized to either the low-dose (n=20) or high dose (n=20) group and dispensed medication daily for one week. Thereafter, they will be treated according to the MATClinics usual schedule of clinic visits. The number and timing of visits may vary according to whether the participant is still using illicit opioids. Follow-up visits for the study will be at one and three months.The primary objective is to determine whether patients randomly assigned to low versus high dose induction regimens are more likely to complete the 7-day induction period. Secondary outcomes are the number of patients who develop precipitated withdrawal or other adverse events, experience subjective opioid withdrawal symptoms, use adjunctive medications (hydroxyzine, loperamide, dicyclomine, clonidine, ibuprofen, methocarbamol, trazodone, ondansetron) provided by the clinic, recommendation of the medication induction scheme to other patients, and treatment retention at 1- and 3- months post induction.

low dosebuprenorphine/naloxoneLow dose: Participants randomized to the low dose group will receive 0.5 mg of buprenorphine/naloxone on day 1, 0.5 mg bid on day 2, 1.0 mg bid on day 3, 2.0 mg bid on day 4, 4.0 mg bid on day 5, 4.0 mg tid on day 6, and 8 mg bid on day 7. Thereafter, dosing adjustments can be made in the first three months of the trial.
high dosebuprenorphine/naloxoneHigh dose: Participants randomized to the high dose group will receive on day 1 in the clinic an initial dose of 2 mg of buprenorphine/naloxone, followed by a 6 mg dose an hour later, followed by an 8 mg dose an hour later, followed by an 8 mg dose an hour later. On day 2 they will receive a 12 mg dose in the clinic and a 12 mg dose as take-home medication. On days 3 through 7 they will report to the clinic and receive their 12 mg morning dose and a 12 mg dose as a take-home for evening dosing. Thereafter, dosing adjustments can be made in the first three months of the trial.
