Sixty-two percent of the patients were diagnosed with schizophrenia, and the remainder 38% were diagnosed with schizoaffective disorder. Only about one-fourth of the total patient population 27% was identified as “treatment-resistant” at baseline. There were more males than females in the study 61% of all patients were male. The mean age of patients entering the study was 37 years of age range 18 to 69. Most patients were Caucasian 71% 15% were Black, 1% were Asian, and 13% were classified as being of “other” races.

Neutropenia reported in clozapine-treated patients. However, this increase is not clinically significant. Importance of advising patients and caregivers that geriatric patients with dementia-related psychosis treated with antipsychotic agents are at an increased risk of death. 1 Patients and caregivers also should be informed that clozapine is not approved for treating geriatric patients with dementia-related psychosis. In a pooled data analysis of 10 studies in adult subjects with schizophrenia, clozapine treatment was associated with increases in serum total cholesterol. No data were collected on LDL and HDL cholesterol.

Benign ethnic neutropenia BEN is a condition observed in certain ethnic groups whose average ANC values are lower than “standard” laboratory ranges for neutrophils. It is most commonly observed in individuals of African descent approximate prevalence of 25-50% some Middle Eastern ethnic groups, and in other non-Caucasian ethnic groups with darker skin. BEN is more common in men. Patients with BEN have normal hematopoietic stem-cell number and myeloid maturation, are healthy, and do not suffer from repeated or severe infections. They are not at increased risk for developing clozapine-induced neutropenia. Additional evaluation may be needed to determine if baseline neutropenia is due to BEN. Consider hematology consultation before initiating or during Clozapine Orally Disintegrating Tablets treatment as necessary. flucort
