Efficacy of Galantamine to Treat Schizophrenia

Stopped early · Phase 4

Conditions studied: Schizophrenia, Psychotic Disorder

In brief

The purpose of this study was to determine if treatment with adjunctive galantamine is effective in the reduction of functional impairments in patients with schizophrenia and schizoaffective disorder. It was hypothesized that adjunctive galantamine would yield clinically significant improvements from baseline to end of study on a measure of quality of life and a measure of independent living skills.
