Maintaining therapeutic plasma concentrations of an antipsychotic agent is essential in preventing relapse of symptoms in schizophrenia. Long-acting injectable (LAI) formulations provide extended exposure to antipsychotic therapy and have been useful in addressing treatment nonadherence. Aripiprazole is an atypical antipsychotic used in the treatment of schizophrenia and is available in 2 chemically different (aripiprazole monohydrate and aripiprazole lauroxil [AL]) and pharmaceutically different LAI formulations (aripiprazole once-monthly 400 mg [AOM 400] and AL)...

BACKGROUND AND OBJECTIVE: Patient characteristics require consideration for optimal treatment in order to achieve clinical remission for an improved quality of life and social functioning. Prior evidence supports long-acting injectable antipsychotics (LAIs) in the relapse prevention of schizophrenia. This study aimed to characterize Japanese patients diagnosed with schizophrenia and to compare the outcomes of LAIs and oral antipsychotics (AP) in re-hospitalization or emergency room visit rates...

Early-onset bipolar disorder is difficult for child psychiatrists in terms of both diagnosis and treatment. The proper diagnostic evaluation is negatively impacted by the atypical clinical manifestation and rapid cycling pattern of the disease, together with common comorbidity with attention-deficit hyperactivity disorder and anxiety disorder. In addition to poor insight, nonadherence to treatment, poor family coping skills, and insufficient child psychiatric inpatient units make clinicians unsuccessful in following up and treating such patients...

Paliperidone palmitate 3-month formulation (PP3M), a long-acting injectable atypical antipsychotic, was recently approved in the US and Europe for the treatment of schizophrenia in adult patients who have already been treated with paliperidone palmitate 1-month formulation (PP1M) for ≥4 months. This article reviews the pharmacokinetic rationale for the approved dosing regimens for PP3M, dosing windows, management of missed doses and treatment discontinuation, switching to other formulations, and dosing in special populations...

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...

Since the therapeutic treatment of depression is far from being satisfactory, new therapeutic strategies ought to be pursued. In addition, further investigation on brain areas involved in the action mechanism of antidepressants can shed light on the aetiology of depression. We have previously reported that typical and atypical antidepressants strongly stimulate catecholamine transmission in the bed nucleus of stria terminalis (BNST). In this study, we have built on that work to examine the effect of ketamine, an unusual antidepressant that can produce a fast-acting and long-lasting antidepressant effect after administration of a single sub-anaesthetic dose...

Aripiprazole once-monthly (AOM) was previously approved for treatment of schizophrenia as monthly injections in the gluteal muscle. The deltoid muscle provides a more accessible injection site. The present study was conducted in Japanese schizophrenia patients as a 24-week, open-label trial that assessed the pharmacokinetics and safety of 5 sequential doses of AOM 400 mg (AOM 400) once every 4 weeks administered in the deltoid muscle. Patients treated with an oral atypical antipsychotic (other than aripiprazole) continued to receive their pre-study medication up to 14 days after the first AOM 400 injection...

OBJECTIVE: Patients with chronic schizophrenia suffer a huge burden, as do their families/caregivers. Treating schizophrenia is costly for health systems. The European Medicines Agency has approved paliperidone palmitate (PP-LAI; Xeplion), an atypical antipsychotic depot; however, its pharmacoeconomic profile in Portugal is unknown. A cost-effectiveness analysis was conducted from the viewpoint of the Portuguese National Health Service. METHODS: PP-LAI was compared with long acting injectables risperidone (RIS-LAI) and haloperidol (HAL-LAI) and oral drugs (olanzapine; oral-OLZ) adapting a 1-year decision tree to Portugal, guided by local experts...

Myasthenia gravis is an autoimmune disease characterized by muscle weakness due to autoantibodies affecting the neuromuscular junction. Co-occurrence of myasthenia gravis and schizophrenia is very rare and raises a challenge in management of both diseases. Antipsychotic drugs exhibit anticholinergic side effects and have the potentials of worsening myasthenia. Long-acting risperidone is an injectable atypical antipsychotic drug that has not been previously reported to worsen myasthenia gravis in literature...

Schizoaffective disorder (SAD) is an incapacitating illness that presents clinicians with challenges in terms of both its diagnosis and its psychopharmacological management. Most studies conducted on the psychopharmacological treatment of SAD also include patients with schizophrenia or other psychotic illnesses, thereby providing an unspecific view to the clinician as to the best way of treating patients with SAD. The objective of this article is to review studies on evidence-based treatment of patients with SAD...

BACKGROUND: Neuroleptic malignant syndrome (NMS) is an uncommon but potentially fatal adverse effect of neuroleptic drugs. It is commonly characterized by muscular rigidity, fever, altered mental status, and autonomic dysfunction. Emerging of NMS is possible with all neuroleptics, classic and atypical. NMS occurs most often during the first week of treatment or after increasing the dosage of the neuroleptic medication. The frequency of NMS ranges from 0.07 to 2.2%. Its pathophysiology is not clearly understood but the blockade of dopamine receptors appears to be the central mechanism...

BACKGROUND: Compared to oral atypical antipsychotics (OAAs), long-acting injectable antipsychotics require less frequent administration, and thus may improve adherence and reduce risk of relapse in schizoaffective disorder (SAD) patients. OBJECTIVE: To evaluate the impact of once monthly paliperidone palmitate (PP) versus OAAs on healthcare resource utilization, Medicaid spending, and hospital readmission among SAD patients. METHODS: Using FL, IA, KS, MS, MO, and NJ Medicaid data (January 2009-December 2013), adults with ≥2 SAD diagnoses initiated on PP or OAA (index date) were identified...

BACKGROUND: Schizophrenia is a severe and debilitating psychiatric disorder. Pharmacological interventions aim to ameliorate symptoms and reduce the risk of relapse and costly hospitalisation. Despite the established efficacy of antipsychotic medication, compliance to treatment is poor, particularly with oral formulation. The emergence of long acting injectable (LAI) antipsychotic formulations in recent years has aimed to counteract the poor compliance rates observed and optimise long term patient outcomes...
