The effect of reserpine on concurrent repeated administration of d-amphetamine.
The augmentation of the rat stereotypy response with repeated amphetamine doses, put forward as a model of human amphetamine psychosis, was examined during concurrent reserpinization. The effects of reserpinization, amphetamine treatment, and amphetamine dose on four dependent variables representing the time course of stereotypy ratings after a post-treatment amphetamine dose, were tested by three-way MANOVA. An earlier onset of stereotypy , as occurred in nonreserpinized rats, was not detected in reserpinized rats, but an earlier offset of stereotypy with repeated amphetamine occurred in these rats when high amphetamine doses were used.
