Background And Objective:
Many patients are unable to initiate long-acting injectable naltrexone (XR-NTX) on a first attempt, due to the prerequisite abstinence and withdrawal from opioids.
Methods:
Thirty patients who were unable to initiate XR-NTX were recruited to receive buprenorphine for 1 week, followed by a 3-week buprenorphine taper, and an ascending titration of oral naltrexone before XR-NTX injection.
Results:
Eight (27%) initiated XR-NTX, 7 (23%) transitioned to buprenorphine maintenance treatment and 15 (50%) were lost to follow up.
Conclusion And Scientific Significance:
A second attempt at XR- NTX initiation using buprenorphine stabilization and cross taper may be a reasonable approach for some patients.
