Buprenorphine (BUP) is FDA-approved for the treatment of opioid withdrawal and opioid use disorder. Few ED providers have received the necessary DEA registration (aka X waiver) required to prescribe BUP, and urgent appointments to continue ongoing BUP treatment may not be readily available, thus leading to medication discontinuity. A loading dose induction strategy with 32mg of BUP may help effectively link ED patients to outpatient treatment while minimizing known barriers to ED uptake. Administering a "loading dose" of BUP to saturate mu-opioid receptors would extend the duration of action and provide additional time to secure ongoing treatment. Further, BUP's ceiling effect on respiratory depression makes it a remarkably safe drug even at high doses. In recent years, ED providers have begun to incorporate this approach into clinical protocols, however, it has not been formally studied in this clinical setting. The investigator's study represents the necessary step of studying this novel approach in the ED setting to define the parameters for clinical protocols and large-scale studies.
A novel induction strategy, in which a loading dose of Buprenorphine (BUP) 32mg is administered, has the potential to mitigate barriers to treatment initiation. ED providers can treat patients with BUP for opioid withdrawal since DEA registration (X-waiver) is not required unless they wish to issue a prescription. Current BUP induction protocols, developed for inpatient and ambulatory care settings as well as for unobserved self- administration via prescription, usually recommend a first day dose of 8mg given in divided doses of 2- 4mg. However, patients discharged with ≤ 8mg SL total dose may experience return of withdrawal symptoms and/or opioid craving within only 4 hours.Treatment with a loading dose of 32mg in the ED may provide the necessary bridge treatment, relieving symptoms of withdrawal until a patient is able to attend a follow up appointment for further treatment.

| Label | Type | Description | Intervention Names |
|---|---|---|---|
| BUP treatment arm | Experimental | Subjects will be given BUP 32mg in 2 doses, and observed for at least 90 minutes after the 2nd dose. The whole process will take a total of about 3-4 hours including the consenting process. Subjects will be asked questions and be examined repeatedly. Subjects will have 4 in-person visits and a phone call in addition to review of medical records. |

| Buprenorphine Naloxone | Drug | Participants will receive the BUP SL 32mg in divided doses rather than all at once. If after the initial 8mg dose a participant experiences over-sedation or another adverse event that would preclude further dosing, such as an allergic reaction, the subsequent dose will not be administered and the patient will be withdrawn from the study. The participant will be reassessed for other possible etiologies for these symptoms. |
| Measure | Description | Time Frame |
|---|---|---|
| Number of Participants With Successful Rapid Induction | This will be measured by the proportion of participants who report Successful Rapid Induction. Participants will receive a loading dose of BUP SL 32mg in the ED without experiencing a clinically significant serious and/or severe adverse event (AE) related to the intervention - specifically, the receipt of a dose of BUP SL greater than 8mg during the Index ED visit. Successful rapid induction is defined only by the outcome of the participant's visit, and not by any following research visits. | Day 0 |

| Opioid Withdrawal at Conclusion of Index Visit as Measured by the Clinical Opiate Withdrawal Scale (COWS) | The Clinical Opiate Withdrawal Scale (COWS) is an 11-item scale designed to be administered by a clinician. The tool can be used in both inpatient and outpatient settings to reproducibly rate common signs and symptoms of withdrawal and monitor these symptoms over time. The summed score can be used to help clinicians determine the stage or severity of withdrawal and assess the level of physical dependence on opioids. The total score ranges from 0 to 48. The interpretation of scores is as follows: 5-12 = mild; 13-24 = moderate; 25-36 = moderately severe; more than 36 = severe withdrawal. |
