PURPOSE: The emergence of electronic prescribing devices with clinical decision support systems (CDSS) is able to significantly improve management pharmacological treatments. We developed a web application available on smartphones in order to help clinicians monitor prescription and further propose CDSS. METHOD: A web application ( was developed to assess patients and collect data regarding gender, age, diagnosis and treatment. We analyzed antipsychotic prescriptions in 4345 patients attended in five Psychiatric Community Mental Health Centers from June 2014 to October 2014...

BACKGROUND: Treatment-resistant schizophrenia (TRS) is a condition characterized by intense symptom severity and poor response to different antipsychotic agents. The first therapeutic option in TRS is clozapine, but often high/medium doses are not tolerated. Adding an oral antipsychotic to low doses of clozapine is a promising strategy in the management of TRS. On the contrary, there are few data on combined clozapine/long-acting injectable (LAI) medications, and none on clozapine/LAI-aripiprazole...

Antipsychotic drugs, all of which block the dopamine D2 receptor to a greater or lesser extent, are the mainstay for the pharmacological treatment of schizophrenia. Engaging in a deeper understanding of how antipsychotics act on the brain and body, at the cellular, molecular and physiological level is vital to comprehend both the beneficial and potentially harmful actions of these medications and stimulate development of novel therapeutics. To address this, we review recent advances in our understanding of neuroadaptations to antipsychotics, focusing on (1) treatment efficacy, (2) impact on brain volume and (3) evidence from human post-mortem studies that attempt to dissect neuropathological effects of antipsychotic drugs from organic schizophrenia neurobiology and (4) cardio-metabolic side effects...

BACKGROUND: Risperidone long-acting injection (RLAI) is increasingly being switched to paliperidone palmitate (PP) because of several benefits. However, this switching is not always successful. METHODS: We examined patient profiles following discontinuation of PP after switching from RLAI. We collected the electronic records of 24 patients with schizophrenia who had switched from RLAI to PP treatment at our hospital between November 2013 and March 2014. Twelve patients continued PP injection for over 1 year (PP-continuers), the other 12 patients discontinued within 1 year (PP-discontinuers), and both groups were followed up until December 31, 2014...

Long-acting injectable antipsychotics (LAIs) are among the most effective treatments in psychiatry, yet they remain underutilized in clinical practice. Although LAIs are typically used to maintain treatment adherence in patients with chronic schizophrenia, recent research has suggested that they may also provide an effective treatment strategy for patients with early-phase or first-episode disease. In October 2015, a group of 8 experts on the management of schizophrenia and LAIs met to evaluate the evidence surrounding the efficacy, safety, and cost-effectiveness of LAIs and to develop practical recommendations regarding the clinical use, education, and unmet needs related to LAIs...

OBJECTIVES: Olanzapine is a well established treatment for schizophrenia. The olanzapine pamoate depot (long-acting injectable) formulation improves compliance and clinical trials have shown it to be effective. However, there are no previously published reports evaluating olanzapine depot in violent patients with schizophrenia in the community. We evaluated the clinical efficacy of olanzapine depot, its effect on violence, hospitalization and incarceration in community patients with schizophrenia and prior history of serious violence...

Younger patients with schizophrenia have most likely experienced fewer adverse consequences of the illness than older patients who may have experienced a lifetime of treatment as well as socio-economic problems as a consequence of the illness. There is limited information regarding differential efficacy of long-acting injectable (LAI) antipsychotic medications across the age span in patients with schizophrenia. We conducted a post hoc age and gender analysis of treatment response to aripiprazole lauroxil (AL; ARISTADA®; Alkermes, Inc...

New-onset psychotic symptoms often respond well to antipsychotic treatment; however, symptoms may be difficult to treat when an underlying brain malformation is present. Here, we present a case of atypical psychotic symptoms in the context of a congenital cerebellar malformation (Dandy-Walker variant). The patient ultimately improved with paliperidone palmitate after multiple antipsychotic medication trials (both oral and one long-acting injectable) were ineffective. Neuroimaging may provide valuable diagnostic and prognostic information in cases of new-onset psychosis with atypical features and treatment resistance, even in the absence of neurologic signs and symptoms...

BACKGROUND: It has been shown that patients' attitudes towards long-acting injectable antipsychotics (LAIA) have the influence on the acceptance and use of this type of therapy. The aim of our study was to explore attitudes of patients because, according to our knowledge, there has been no similar research in Croatia thus far. SUBJECTS AND METHODS: Two questionnaires were given to the total of 100 patients, the first one to patients treated with LAIA (group 1) and the second one to patients treated with oral antipsychotics (group 2)...

BACKGROUND: Despite many advantages of long-acting injectable antipsychotics (LAIA), this type of therapy is still underused in routine practice. Since psychiatrists' attitudes play an important role in prescription rate of LAIA, we found it valuable to examine their attitudes because, according to our knowledge, there hasn't been similar research in Croatia so far. SUBJECTS AND METHODS: In this research, we included the total of 48 psychiatrists. For research purposes, we created a questionnaire modeled on standardized questionnaire...

INTRODUCTION: Dopamine D2 receptor occupancy levels needed for the maintenance treatment of schizophrenia remain to be elucidated. We examined 3-year clinical outcomes of patients with schizophrenia who received long-acting injectable risperidone (LAI risperidone) at baseline and investigated their dopamine D2 receptor occupancy levels, estimated from plasma drug concentrations. METHODS: A chart review of 52 outpatients with schizophrenia who participated in the original cross-sectional study was conducted to examine their 3-year clinical outcomes between April and September 2015...

OBJECTIVE: To explore the impact of the introduction of newer antipsychotic long-acting injections (LAIs) on trends in LAI prescribing and characteristics associated with initiation of LAIs in naturalistic conditions. METHODS: The study was performed using reimbursement data from the French Insurance Healthcare system. Prescribing trends were investigated from 2007 to 2014 in 382,572 persons aged 18years and over. Characteristics associated with delay in transition from oral antipsychotic to LAIs were explored in a cohort of 6904 persons newly treated with an oral antipsychotic using multivariate survival analyses...

INTRODUCTION: The course of schizophrenia can vary widely, and patients experience remission phases alternating with relapse episodes, which generally lead to hospitalisation and have a significant impact on the burden of disease. The prevalence of schizophrenia in France is estimated to be approximately 600,000 people, with an incidence of 10,000 new patients per year. Patients with schizophrenia represent the largest group of hospitalised patients in French public institutions and specialised centres, and the French authorities recognise that the management of schizophrenia is a major public health concern...

Intravenous haloperidol has been associated with torsades de pointes (TdP). These two sudden deaths were probable adverse drug reactions (ADRs) following intramuscular (IM) antipsychotics. The autopsies described lack of heart pathology and were highly compatible with the possibility of TdP in the absence of risk factors other than the accumulation of antipsychotics with a high serum peak after the last injection, leading to death within hours. The first case was a 27-year-old African-American male with schizophrenia but no medical issues...

We conducted a cross-sectional study to compare the subjective experiences and clinical effects of first-generation long-acting injectable (FGA-LAI) antipsychotics with those of risperidone long-acting injectables (RIS-LAIs) in 434 schizophrenia patients. Compared with the RIS-LAI group, the patients treated with FGA-LAIs had a significantly longer duration of illness and LAI treatment and were older. Our results suggest that patients treated with FGA-LAI have more satisfactory subjective experiences compared with patients treated with RIS-LAI and that both FGA-LAI and RIS-LAI treatments can prevent relapses and hospitalization...

OBJECTIVE: Aripiprazole lauroxil, a long-acting injectable antipsychotic, demonstrated safety and efficacy in treating symptoms of schizophrenia in a double-blind, placebo-controlled trial. Because the metabolic profile of antipsychotics is an important safety feature, the effects of aripiprazole lauroxil on body weight, endocrine and metabolic profiles, and safety were examined in a secondary analysis. METHODS: Patients with schizophrenia (DSM-IV-TR criteria) were randomly assigned to aripiprazole lauroxil 441 mg, aripiprazole lauroxil 882 mg, or placebo intramuscularly once monthly between December 2011 and March 2014...

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...

After 1 year of introduction of olanzapine long-acting injectable (LAI) in India, many psychiatrists believe that it is a very affordable, well-tolerated, and effective second generation long-acting antipsychotic depot compared to not well tolerated but cheap first generation antipsychotic depots and to other second generation depots which are costly. However, reports of its possible adverse events in clinical settings are not yet published. We report what probably might be the first case of postinjection delirium/sedation syndrome (PDSS) in India...
