简要总结

The aim of this study is to investigate which method of naltrexone induction during rapid opioid detoxification causes stronger stress response and has a higher influence on opioid abstinence caused by opioid induction.

详细描述

Study enrolls opiate addicted patients who are motivated for a long term treatment and full opiate abstinence. Patient is offered to take part in a study. Information is provided regarding protocol, aim and course of study. Patients who are eligible and consent for study commit to follow the pre-study recommendations.

Study consists of:

Primary assessment - information about study. Assessment of patient according to predefined criteria. Consent form. Allocation of the treatment date.

Stabilization - Buprenorphine. Assessment according to SOWS and OWS. Total amount of buprenorphine is recorded.

Repeated evaluation - patient after successful stabilization course undergoes urine test for psychotropic substances, blood alcohol level is recorded. If any test is positive patient is not enrolled to study.
