Some behavioral effects of prethcamide compared with those of its two components.
The effects of the two components of prethcamide (namely crotetamide and cropropamide) upon various behaviors in rats were compared with those of prethcamide itself to see if both were active or not and the kind of joint action shown when they were given in combination. Both crotetamide and cropropamide increase the motor activity of rats, reduce the rate of lever pressing in FR and VI food-reinforced schedules and increase the latency times in a multiple CRF-discrimination schedule. When given in combination the drugs show additive effects upon locomotor activity and FR or VI behaviors but they potentiate each other as regards the effects upon latency times in the multiple schedule. On the other hand, a clear antagonism between the two drugs has been found in the acute toxicity test.
