Relationship Between D2 Receptors SPECT and the Apomorphine Test in Patients With OH Dependence (ALC-DRD2-APO)

This study is currently recruiting participants.

Verified by Hospital University Vall d'Hebron, June 2008

Sponsored by:	Hospital University Vall d'Hebron
Information provided by:	Hospital University Vall d'Hebron
ClinicalTrials.gov Identifier:	NCT00437177

Purpose

OH dependence is associated with DA receptor changes. Both, the apomorphine test and the D2Rec SPECt are usefull for monitoring DA receptor status. We aimed at studying whether DA receptor hypofunction, assessed by means of the apomorphine test and the D2Rec SPECT, is a marker of relapse in detoxified OH dependents patients.
