Biperiden is one of the most commonly abused anticholinergic drugs. This study assessed its motivational effects in the acquisition of conditioned place preference in rats. Biperiden neither produced place conditioning itself nor enhanced the rewarding effect of morphine. Furthermore, biperiden in combination with haloperidol also did not affect place preference. These findings suggest that biperiden seems devoid of abuse potential properties at least at the doses used. (C) 2011 Elsevier B.V. All rights reserved.
