Abstract
d-Amphetamine reduced the milk consumption of fasted mice in a dose-related manner. Each dose level of d-amphetamine reduced milk intake by a fixed amount, which increased with dose, but which appeared to be independent of the level of milk intake of the concurrent control animals. These data suggest that the anorexic effects of d-amphetamine did not conform to the law of initial value; that is, following drug administration, the magnitude of response of the test system was not a function of, the initial state of the system.
