Background:Naltrexone is a competitive opioid receptor antagonist blocking the euphoric effects of exogenous opioids. When used concomitantly with opioids, naltrexone causes severe withdrawal symptoms.The main aim of the study is to determine the symptomatology and outcome of patients who consumed naltrexone in conjunction with an opioid substance.
Methods:This cross-sectional study was performed on the patients hospitalized with history of naltrexone usage coincided with opioid substances at Razi Hospital, Rasht, Iran. The collected data were demographic information, abuse information, clinical signs and symptoms, laboratory findings, and therapeutic measures taken. Data analysis was performed by descriptive tests using SPSS software version 16.
Results: The mean age of the patients was 33.7±10.2. The majority of the cases were male (95.6%) and urban (96.7%). The main cause of withdrawal symptoms in 91.1% of the patients was inappropriate naltrexone usage.The main poisoning agent in 80% of the cases was consumed naltrexone alone. The route of consumption in 90.1% of the cases was oral and in 9.9% the cases was IV injection. The major clinical features were nausea, vomiting, and agitation.The main therapeutic measures were supportive intravenous fluids (94.8%) and opioid administration in the form of methadone. The mean hospitalization period was 21.8±18 hours.
Conclusion: Severity, clinical course, and outcome of opioid withdrawal by accidental or intentional naltrexone abuse varies greatly among patients and is unpredictable. Common findings upon presentation were gastrointestinal symptoms and agitation and the main therapeutic measures for these patients were support with intravenous fluids and anti-nausea drugs administration as plasil and opioid administration as methadone.
