Abstract
BACKGROUND: Although opioid agonist treatments (OAT) with methadone or buprenorphine are available to treat opioid use disorders (OUD) in Ukraine, OAT acceptability and coverage remains low. Extended-release naltrexone (XR-NTX) that recently became available as another treatment option provides new opportunities for treating OUDs in this region and we aimed to test its feasibility. METHODS: Patients with OUD (N=135) and interested in treatment with XR-NTX were initiated on monthly XR-NTX injections and monitored for three months. Correlates of 3-month retention on XR-NTX and drug use at each time-point using self-reports and urine drug testing (UDT) were assessed. RESULTS: Of the 134 participants initiated XR-NTX, 101 (75%) completed three months, defined as 4 consecutive XR-NTX injections. Independent factors negatively associated with retention in XR-NTX treatment included previous maintenance with OAT (aOR=0.3; 95%CI=0.1-0.9) and extrinsic help-seeking treatment motivation (aOR=0.7; 95%CI=0.5-0.9). Of these 101 participants completing three months of treatment, opioid use markedly reduced using self-report (67%% to 22%; p>0.001) and UDT (77% to 24%; p<0.001) outcomes over time. Alcohol, marijuana and stimulant use, however, remained unchanged. Craving for opioids and symptoms of depression also significantly decreased, while health-related quality of life scores improved over time. No adverse side effects were reported during the period of observation. CONCLUSION: The first introduction of XR-NTX in Ukraine among persons with OUD resulted in high levels of retention, marked reductions in opioid use and improved quality of life. These descriptive results suggest that XR-NTX treatment is feasible and well-tolerated over a 3-month period in Ukraine.
