Paroxetine, also known by the trade names Aropax, Paxil, Pexeva, Seroxat, Sereupin and Brisdelle, was first marketed in the U.S. in 1992. Effective for major depression and various anxiety disorders, it quickly gained a sizable share of the antidepressant prescription market. By the late 1990s, paroxetine frequently was being associated with serious drug interactions and medication side effects. Most significantly, in a major Canadian epidemiological study examining the relationship between antidepressants and diseases, paroxetine was associated with a 620 percent increase in the rate of breast cancer in women who had taken it over a four-year period...

AIMS: Pharmacovigilance databases are usually used to detect new potential signals relevant for drug safety. They are seldom used for explanatory purposes, e.g. to understand the mechanisms of adverse drug reactions (ADRs). The aim of the present study was to combine pharmacovigilance and pharmacodynamic data to investigate the association between D2, 5HT2A, and M1 receptor occupancy and the risks of antipsychotic (AP)-induced movement disorders. METHODS: First, we performed a case non-case analysis using spontaneous reports from the World Health Organization (WHO) Global Individual Case Safety Report (ICSR) database, VigiBase®...

Schizophrenia occurs in approximately 0.3 to 0.7 percent of the world's population and is associated with significant morbidity and mortality. Although atypical antipsychotics reduce positive and negative symptoms, they are associated with varying degrees of metabolic adverse effects. This necessitates continued development of efficacious yet metabolically favorable treatments. This article reviews brexpiprazole, a medication recently approved to treat patients with schizophrenia. Brexpiprazole was well-tolerated, and adverse reactions were statistically insignificant...

This report describes two cases in which pharmacogenomic testing was utilized to guide medication selection for difficult to treat patients. The first patient is a 29-year old male with bipolar disorder who had severe akathisia due to his long acting injectable antipsychotic. The second patient is a 59-year old female with major depressive disorder who was not responding to her medication. In both cases, a proprietary combinatorial pharmacogenomic test was used to inform medication changes and improve patient outcomes...

Cariprazine is an antipsychotic medication and received approval by the U.S. Food and Drug Administration for the treatment of schizophrenia in September 2015. Cariprazine is a dopamine D3 and D2 receptor partial agonist, with a preference for the D3 receptor. Cariprazine is also a partial agonist at the serotonin 5-HT1A receptor and acts as an antagonist at 5-HT2B and 5-HT2A receptors. The recommended dose range of cariprazine for the treatment of schizophrenia is 1.5-6 mg/d; the starting dose of 1.5 mg/d is potentially therapeutic...

BACKGROUND: Both the US FDA and the European Medicines Agency (EMA) have approved aripiprazole for use in adolescents for specific indications. Given the assumed favorable side-effect profile of aripiprazole, its use in children and adolescents has increased for both official and off-label indications (anxiety disorders, eating disorders, personality disorders). However, several cases of children and adolescents with new-onset extrapyramidal symptoms (EPS) after commencing treatment with aripiprazole have been reported, and a more systematic appraisal of this possible risk is lacking...
