入选标准
- •18-65 year-old men and women with a ICD-10 diagnosis of schizophrenia (F20.00-20.39, F20.5, F20.9) who have had the disorder for at least 5 years and who are on disability pension. (This means that their treatment response is not satisfactory and for the purpose of this study, the subjects are potentially treatment resistant).
- •Clinical Global Impression (CGI) severity score of at least 3.
- •No changes in schizophrenia treatment within 12 weeks before study inclusion.
- •Written informed consent
- •The subjects must fulfil schizophrenia criteria both according to DSM-IV (295.10, .20, .30, .60, .90) (American Psychiatric association) and the Research Diagnostic Criteria for schizophrenia (RDC) [40]. They must also have at least mild residual symptoms (CGI 3 points). The DSM-IV diagnosis will be verified by use of the SCID-I [41]. The DSM-IV is clearly the most commonly used in psychiatric research, so this is important to be able to generalize the findings. However, several previous studies have used the RDC, so to be able to compare the results, we will diagnose the patients according to both systems.
- •Women of child-bearing age will be included only of they use adequate contraception, or if we can otherwise verify that the subject is not pregnant (s-HCG), the possibility of pregnancy is negligible (e.g. the personnel of the housing facility reports that the person has not had sexual relationships for years) and the subject approves to remain sexually abstinent for the duration of the study.
- •Are the trial subjects under 18? no
- •Number of subjects for this age range:
- •F.1.2 Adults (18-64 years) yes
- •F.1.2.1 Number of subjects for this age range 140
- •F.1.3 Elderly (>=65 years) yes
- •F.1.3.1 Number of subjects for this age range 10
排除标准
- •Patients will be excluded if they have any of the following criteria
- •Epilepsy or a history of unclear seizures, stroke, Parkinson’s disease, AIDS
- •History of substance addiction or abuse within 3 months prior to enrolment.
- •Individuals who are deemed at risk for aggressive behaviour or suicide are likewise ex-cluded.
- •If their laboratory tests, EKG or other clinical observation warrants exclusion, they will be excluded
- •Women who are pregnant or breast-feeding subjects will not be included in the study.
- •Patients with any serious unstable physical illness will also be excluded
- •Patients who have been deemed to be legally incapacitated according to Finnish or Swedish law.
- •Regular Use of H2-antagonists as prescribed by a physician.
- •Present medication with clozapine.
- •Known allergy to famotidine or any other component of the study drug will be excluded.
- •Ongoing treatment with clozapine and dixyrazine.
- •Clinical condition ”very much improved” or ”much improved”, assessed by CGI, during the placebo lead-in.
- •Renal insufficiency (P-creatinine not within normal rangeGlomerular filtration rate <30 ml/min according to the Cockcroft-Gault formula. ).
- •Liver insufficiency (S-ALAT elevated more than 2-fold above the laboratory specific normal range).
