Detailed Description:
Epidemiological evidence shows a potentially protective role for estrogen in women with schizophrenia. The onset of schizophrenia is later in woman than in men, with generally a less severe course until after the menopause, when for many women, reductions in estrogen levels appear to trigger an exacerbation or illness (Hafner 2003). ERα (Estrogen receptor alpha) expression is known to be reduced in schizophrenia (Wong, Woon et al. 2010). Raloxifene is a selective estrogen receptor modulator that acts as an estrogen antagonist in breast tissue and may have agonistic actions in the brain. Several studies (Kulkarni, Riedel et al. 2001; Chua, de Izquierdo et al. 2005; Kulkarni, Gurvich et al. 2010) indicate that treatment with estrogen and raloxifene improves symptoms in females with schizophrenia, and recently they showed an improvement in PANSS score in post menopausal women with schizophrenia receiving 60-120mg/d of raloxifene compared to placebo

Ages Eligible for Study:   45 Years to 65 Years   (Adult)
Sexes Eligible for Study:   Female
Accepts Healthy Volunteers:   No

Inclusion Criteria:

  1. Post menopausal females: Post menopausal defined as: Women 45 years of age and older with no vaginal bleeding for at least 2 years prior to randomization, and both serum estradiol <73 pmol/L (20 pg/mL) and FSH >30 IU/L (30 mIU/mL).
  2. 45-65 years old
  3. Willing and able to provide informed consent, after the nature of the study has been fully explained.
  4. Current DSM-IV-TR diagnosis of schizophrenia or schizoaffective disorder as confirmed by modified SCID and having had at least 2 prior schizophrenic episodes, or continually ill for at least 6 months.
  5. Symptoms: 4 (moderate) or above on CGI-S and 4 (moderate) score or above on two of the following four PANSS items: delusions, hallucinatory behaviors, conceptual disorganization or suspiciousness/ persecution, and/or a total PANSS negative symptoms score of 18.
  6. Must be on any antipsychotic drug, for at least 2 weeks prior to the baseline visit, at doses within the PORT criteria, whenever possible. Patients receiving higher doses will have their records reviewed to insure that the dose is required and, if possible, will be stabilized on a lower dose prior to study entry.
  7. Inpatients or outpatients. Inpatients will be randomized 3 days or more after admission.

Exclusion Criteria:

  2. Women of child bearing potential.
  3. Women who have amenorrhea due to causes other than natural or surgical menopause i.e. eating disorders or exercise
  4. Unstable medical disease (malignancy, poorly controlled diabetes, active ischemic cardiac disease, or cardiomyopathy, serious pulmonary disease, kidney disease, impaired liver functioning.
  5. Patients treated with cholestyramine, warfarin or concurrent systemic estrogen therapy
  6. Likely allergy or sensitivity to raloxifene.
  7. At significant risk of committing suicide, or in the opinion of the Investigator, currently is at imminent risk of suicide or harming others.
  8. Patients with a current DSM-IV substance or alcohol abuse. Patients with a history of and/or current recreational use of cannabinoids or alcohol, and/or patients who smoke cigarettes can be included.
  9. Concurrent delirium, mental retardation, drug-induced psychosis, or history of brain trauma.
  10. Patients with hypercoaguable conditions or risk of venous thrombosis.
