Atypical antipsychotic agents seem to be effective treatments for bipolar disorder, especially as adjunctive treatments. They may be a safer and more effective alternative to the common practice of maintenance adjunctive treatment with traditional antipsychotic agents in patients with bipolar disorder. However, currently available research studies are limited methodologically mainly to open-lab...

OBJECTIVE Up to 40% of patients with schizophrenic psychoses have symptoms that are resistant to monotherapy with antipsychotic drugs. In consequence, combinations of drugs are often used, especially based on the antipsychotic agents clozapine and olanzapine because of their broad receptor-interaction profile. The aim of this review was to provide a critical overview of the published results of...

BACKGROUND Some antipsychotic agents have been indicated as a possible risk factor for venous thromboembolism (VTE) in adult patients with psychiatric disorders. The aim of this study was to estimate the effect of atypical and conventional antipsychotic agents on the risk of hospitalization for VTE among elderly patients. METHODS We conducted a retrospective cohort study on nursing home resid...

Antipsychotic agents, utilized for the treatment of a range of psychiatric disorders, differ substantially in terms of their pharmacology and adverse effect profiles. Incomplete and variable efficacy, differences in safety-tolerability, and highly heterogeneous response across individuals prompt development of new agents. Brexpiprazole is one of the two most recently introduced antipsychotic ag...

Acute pancreatitis with antipsychotic treatment is rare but sometimes causes a fatal adverse effect. Most cases of acute pancreatitis due to atypical antipsychotic agents are reported to occur within six months of starting antipsychotic administration. Acute pancreatitis caused by risperidone is rare. The patient had a high fever, stomachache and vomiting. The results of the abdominal computed ...

BACKGROUND Recently, several new atypical antipsychotic agents have been introduced in Ontario, and regulatory warnings have been issued regarding use of atypical antipsychotics in older adults. We sought to establish the impact of newer atypical antipsychotics on prescribing rates and costs. METHODS We performed a population-based cross-sectional study of Ontario adults aged 65 years or more...

The first antipsychotic, chlorpromazine, was used for the treatment of psychosis in France in 1951 and in the United States in 1954. Antipsychotic use has expanded significantly since then. The historic term neuroleptic, used with antipsychotic medication, is no longer appropriate because newer agents cause less sedation. The term antipsychotic is now preferred. In 2009, U.S. poison control cen...

BACKGROUND Evidence suggests that there is an association between antipsychotic drugs and new-onset diabetes, but little is known about the risk of hyperglycemia among persons with preexisting diabetes. METHODS Using a nested case-control design and population-based health databases in Ontario, Canada, persons aged 66 years or older with diabetes who started treatment with an antipsychotic dr...
