Increased Mortality in Elderly Patients with Dementia-Related Psychosis
Elderly patients with dementia-related psychosis treated with antipsychotic drugs are at an increased risk of death. Analyses of seventeen placebo-controlled trials (modal duration of 10 weeks), largely in patients taking atypical antipsychotic drugs, revealed a risk of death in drug-treated patients of between 1.6 to 1.7 times the risk of death in placebo-treated patients. Over the course of a typical 10-week controlled trial, the rate of death in drug-treated patients was about 4.5%, compared to a rate of about 2.6% in the placebo group. Although the cases of death were varied, most of the deaths appeared to be cardiovascular (e.g., heart failure, Sudden death) or infections (e.g., pneumonia) in nature. Observational studies suggest that similar to atypical antipsychotic drugs, treatment with conventional antipsychotic drugs may increase mortality. The extent to which the findings of increased mortality in observational studies may be attributed to the antipsychotic drug as opposed to some characteristic(s) of the patients is not clear. Loxapine is not approved for the treatment of patients with dementia-related psychosis (see WARNINGS).

LOXAPINE SUMMARY
Loxapine, a dibenzoxazepine compound, represents a subclass of tricyclic antipsychotic agents, chemically distinct from the thioxanthenes, butyrophenones, and phenothiazines.
Loxapine Capsules, USP are indicated for the treatment of schizophrenia. The efficacy of loxapine succinate capsules in schizophrenia was established in clinical studies which enrolled newly hospitalized and chronically hospitalized acutely ill schizophrenic patients as subjects.

Immune System Activated In Schizophrenia
Source: Immune System / Vaccines News From Medical News Today [2009.11.19]
Researchers at the Swedish medical university Karolinska Institutet have discovered that patients with recent-onset schizophrenia have higher levels of inflammatory substances in their brains. Their findings offer hope of being able to treat schizophrenia with drugs that affect the immune system. The causes of schizophrenia are largely unknown, and this hinders the development of effective treatments.

The role of metabolites in a bioequivalence study 1: loxapine, 7-hydroxyloxapine and 8-hydroxyloxapine. [1993.04]
Loxapine is a drug which is used in the treatment of psychotic disorders. The drug is extensively biotransformed in humans to produce a variety of metabolites, some of which have pharmacological activity.In fact, the within-subject variabilities of the metabolites were relatively low, so that the 90% confidence intervals for ln AUC0 infinity, ln AUC0t and ln Cmax calculated for the metabolites, were narrower that those for the parent drug.(ABSTRACT TRUNCATED AT 250 WORDS).
