Abstract
The relationship between benzodiazepine-withdrawal induced weight loss and conditioned taste aversion was studied. Rats were treated with chlordiazepoxide (CDP) for 10 days (n = 37) or with vehicle (n = 39). Significant withdrawal-induced weight loss was observed. On day 11 all animals received an intra-oral infusion of saccharin. In a subsequent saccharin vs water choice test significant withdrawal-induced conditioned taste aversion was observed, as CDP pretreated animals drank less saccharin than controls. The two withdrawal indices were not correlated in the CDP pretreated animals [r = + 0.05], despite the fact that we studied a large group of rats. These data are in agreement with suggestions that drug withdrawal syndromes may be heterogeneous phenomena with a number of different underlying neural mechanisms.
