Aims:
The aim of the present study was to examine the influence of partial NMDA receptor agonist d-cycloserine (DCS) on the extinction of conditioned alcohol-seeking behaviour.
Methods:
For this purpose, rats were administered with DCS 60 min before each successive extinction session. Resumption of alcohol responding was carried out 1 day after the final extinction session.
Results:
We demonstrate that treatment of rats with 5 mg/kg of DCS was capable in facilitating extinction of conditioned alcohol-seeking behaviour, which subsequently reduced the resumption of extinguished operant responding.
Conclusions:
Our study suggests a good rationale for the development of new add-on medications for exposure-based psychotherapy so as to extinguish drug-conditioned appetitive memories in alcohol-dependent patients.
