Second-generation antipsychotics (SGAs) increase weight gain and food consumption in humans and non-human animals. It has been speculated that SGAs increase the reinforcing effects of food, which increases food consumption and drives weight gain. The current study evaluated the effects of risperidone on sucrose reinforcement in male and female C57BL/6J mice using economic demand assessments. Demand for sucrose was measured by varying the fixed ratio (FR) value required to produce sucrose delivery across experimental sessions using five FR values: 1, 5, 15, 30, and 45. The effects of acute risperidone administration on demand for sucrose were first assessed by orally …
