In a previous pilot study, MK-0777–a γ-aminobutyric acid (GABA)(A) α2/α3 partial agonist–was reported to improve delayed memory and cognitive measures of prefrontal cortical function in people with schizophrenia. The current study was designed to further examine the efficacy and safety of MK-0777 for the treatment of cognitive impairments in schizophrenia.
