Acute Pain Episodes in Patients Under Opioid Maintenance Therapy : Clinical Management and Long Term Effects
Acute Pain Episodes in Patients Under Opioid Maintenance Therapy : Clinical Management and Long Term Effects
To define a rational pharmacological management of pain for the subjects under opioid
 maintenance therapy (methadone or buprenorphine), it is first of all necessary to estimate
 the efficiency of the current practices on pain management as well as their potentially
 noxious consequences, in particular on the long term opioid maintenance therapy.

 The objective of the study is to compare the efficiency of the opioid maintenance therapy
 according to the arisen of an acute painful phenomenon requiring an analgesic management for
 these patients. At first, this work will allow to determine the results on acute pain of the
 current practices for these patients. The comparison of the long term consequences on opioid
 maintenance therapy between the patients that presented an acute painful phenomenon and the
 control patients should help to improve acute pain management for these patients while
 limiting the risk of relapse in the abused consumption of psychoactive substances.
Inclusion Criteria:

 -  Patients aged 18 or more.

 -  Patients treated by the same drug (buprenorphine or methadone) since at least 3 months

 Exclusion Criteria:
