Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

Primary objective: To assess the efficacy of adding raloxifene as an adjunct to antipsychotic treatment to improve negative symptoms of schizophrenia in postmenopausal women.

This is a double-blind, randomized, placebo-controlled study of raloxifene as adjuvant treatment to antipsychotic treatment. Treatment period of 12 weeks.

The primary result obtained is that women treated with 60 mg of raloxifene compared to those treated with a placebo show greater improvement in psychotic symptoms. The investigators also found improved response in some aspects of social functioning and neuropsychological functioning.
