Objectives

Narrative objectives1

To examine the effects of facilitation of the NMDA type glutamate receptor function by D-cycloserine on the antipsychotic-resistant symptoms of schizophrenia, we will conduct the clinical study that the schizophrenic patients treated with the ordinary antipsychotic drugs will participated in a double-blind, placebo-controlled, crossover trial of 50 mg/day D-cycloserine added to their medication. The clinical efficacy will be compared 1) between the patients treated with placebo and those with D-cycloserine, and 2) between the placebo-treated period and the D-cycloserine-treated period in the individual patients.
