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.

Off-label medication use. [2012] Prescribing medications for off-label uses is not illegal. Off-label prescribing
includes using medications for unapproved indications; using a drug outside of
the recommended dosage range or duration of use; using a drug in certain
unapproved patient populations, such as those defined by age, sex, or particular
clinical parameters; or intentionally using a medication in a patient who has a
known contraindication.
Efficacy and safety of loxapine for inhalation in the treatment of agitation in patients with schizophrenia: a randomized, double-blind, placebo-controlled trial. [2011.10] CONCLUSIONS: Inhaled loxapine was generally safe and well tolerated and produced rapid improvement in agitated patients with psychotic disorders. Statistically significant differences in efficacy were found for the 10-mg dose compared with placebo, with results suggesting 5 mg may be effective. The delivery of loxapine by inhalation may provide a rapid, well-tolerated option for treating acute psychotic agitation that allows patients to avoid the aversive effects and loss of autonomy often associated with use of intramuscular medications. Further investigation of this new loxapine formulation is warranted. TRIAL REGISTRATION: ClinicalTrials.gov identifier: NCT00369577. (c) Copyright 2011 Physicians Postgraduate Press, Inc.

Loxapine in the Management of Restlessness During Mechanical Ventilation Weaning [Recruiting]
This study aims to assess the efficacy of a drug (loxapine, a neuroleptic) in calming
patients down in a situation of restlessness during mechanical ventilation weaning. This
drug is used for several years to quieten restless patients. Its purpose is to restore
spontaneous breathing sooner and therefore to reduce the risks of intubation and mechanical
ventilation.
