Risperidone in the Treatment of PTSD in Women Survivors of Domestic Abuse and Rape Trauma

Risperidone is an atypical antipsychotic that has been shown to be effective in both the core PTSD symptoms and psychotic symptoms associated with combat-induced PTSD in males. Case series have shown that risperidone is possibly effective in monotherapy or adjunctively in treating PTSD patients. However, risperidone has never been tested in women with severe PTSD. Thus, we propose extending and expanding this research to another antipsychotic, risperidone, in a cohort of women who suffer PTSD as a consequence of domestic violence and/or rape trauma.
