Anxiety Treatment of Opioid Dependent Patients with Buprenorphine: A Randomized, Double-blind, Clinical Trial

Abstract

OBJECTIVE: The objective of this study is to examine the impact of vary doses of buprenorphine on anxiety symptoms in opioid-dependent inpatients over a 7 days period, using a randomized controlled trial design. DESIGN: Patients were randomized to three groups. PATIENTS AND METHODS: Fourteen men who met the Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition criteria for both opioid use disorder and generalized anxiety disorder and were seeking for treatment. INTERVENTION: Patients obtain dosages of 32 mg or 64 mg or 96 mg of buprenorphine as a single dose only and were treated in a psychiatric inpatient unit. Of 14 subjects; 5 (35.7%) obtained 32 mg, 4 (28.6%) obtained 64 mg, and 5 (35.7%) obtained 96 mg of buprenorphine. MEASUREMENTS: Administering daily Hamilton Anxiety Rating Scale and interview. RESULTS: = 0.605). CONCLUSIONS: The outcome suggests a single high dose of buprenorphine can supply a speedy, safe, simple, and suitable means of anxiety treatment. The single high dose of buprenorphine could be a novel mechanism medication that provides a rapid and sustained improvement for generalized anxiety disorder in opioid dependent patients. Placebo-controlled trials of longer duration are needed to evaluate ability, safety, and psychological and physiological influence of extended exposure to this medication.
