Summary
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.
