Treatment of comorbid posttraumatic stress disorder (PTSD) and opioid dependence has been a challenge for many clinicians. There are limited evidence-based guidelines for treatment of this comorbidity. Symptoms of PTSD and opiate dependence may converge, and it is sometimes difficult to differentiate between both conditions. For example, opioid withdrawal symptoms may mimic the hypervigilance and exacerbated startle response of patients with PTSD. A common neurobiologic circuit is suggested for the pathophysiologic mechanism of this comorbidity. There is evidence that opioid substitution therapy may improve treatment outcomes for opioid addiction in patients with comorbid PTSD and opioid dependence. Evidence-based psychotherapeutic intervention is recommended for this population to improve the psychological outcome as well. Combining opioid substitution therapy with evidence-based cognitive behavioral therapy designed for individuals with comorbid PTSD and substance abuse (e.g., Seeking Safety) may improve treatment outcomes in this population. More research is needed to understand the underlying mechanisms for this comorbidity and to improve treatment response.
Patients found to be noncompliant were more likely to suffer from comorbid psychiatric illness. Patients who tested positive for benzodiazepines or cannabis were more likely to be noncompliant with treatment. Although the rate of noncompliance (inaccurate pill count) was high, patients were still found to be taking their prescribed buprenorphine as evidenced by positive UDS for buprenorphine/norbuprenorphine. In addition, our sample had a high rate of negative UDS screens for opioids and cocaine.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
