Summary

The purpose of this study is to determine whether or not people with schizophrenia who take LY2140023 become physically dependent on it, and experience a series of symptoms such as craving to have the drug when they stop using it. This trial consists of two phases: An open-label phase consisting of up to 4 weeks and a double-blind phase consisting of up to 3 weeks.
