Background: We studied the patterns and predictors of long-acting injectable (LAI) antipsychotic (AP) use in the treatment of schizophrenia and the effect of introducing a new LAI (paliperidone palmitate [paliperidone-LAI]) in the Spanish province of Tarragona. Methods: This noninterventional, naturalistic, retrospective study included electronic medical record data from a large population-based database of 1,646 patients who were diagnosed with schizophrenia according to ICD-10 criteria and treated between January 2011 and December 2013...

Available evidence suggests that second-generation atypical antipsychotics are broadly similar to first-generation agents in terms of their efficacy, but may have a more favourable tolerability profile, primarily by being less likely to cause extrapyramidal symptoms. However, atypical antipsychotics are variably associated with disturbances in the cardiometabolic arena, including increased body weight and the development of metabolic syndrome, which may reflect differences in their receptor binding profiles...

Parkinson's disease (PD) has a prevalence of nearly 1 million people in the USA, with increasing incidence in the elderly population. Generally, the age of presentation is between 55 and 65 years, with the likelihood of diagnosis increasing as patients reach the age of 80 years or above. Some of the common treatments for PD increase dopamine levels in the brain. Dopaminergic therapy helps to improve motor and non-motor symptoms, but it is not without risks. Dopaminergic therapy can cause confusion, delirium, and psychotic-like behavior...

BACKGROUND: Sexual dysfunction associated with psychotropic drugs is a threat to patient quality of life and a major reason for non-compliance. Psychotropic agents can impair the sexual response in different ways due to their neurobiological mode of action. OBJECTIVE: Presentation of the frequencies of sexual functional disorders for selected psychopharmacological groups and the available treatment modalities. METHODS: Literature search, selection and review of relevant studies...

Treatment of unipolar depression with currently available antidepressants is still unsatisfactory. Augmentation with lithium or second generation antipsychotics is an established practice in non-responders to antidepressant monotherapy, but is also associated with a substantial non-response rate and with non-tolerance. Based on a systematic review of the literature, including meta-analyses, randomized controlled trials (RCTs), non-randomized comparative studies and case studies, off-label augmentation agents (administered in addition to an antidepressant, without FDA approval for treatment of MDD) were identified and evaluated regarding their efficacy using levels of evidence...

Bipolar disorders belong to the spectrum of mood disorders and represent a serious psychiatric comorbidity. Behaviors adopted by bipolar patients can foster cancer occurrence but also impact its management, especially during acute depressive or manic episode. Oncologists must adapt their protocols in order to obtain the best compliance for treatment and avoid any possible mood destabilization, with the inherent risk of suicidal attempt. Potential interactions between mood-stabilizing agents (lithium, divalproate, atypical antipsychotics, and anticonvulsivants) and oncologic treatment (chemotherapy, targeted therapy, immunotherapy, corticotherapy) will be particularly watched...

WHAT IS KNOWN AND OBJECTIVES: Psychopharmacologic therapy has so far focused on ameliorating disruptive behaviours to improve patient's function and quality of life. Due to the complicated neurobiological aetiology of autism spectrum disorder (ASD), a traditional pharmacist intervention may be insufficient to initiate the optimal care for this vulnerable population. We evaluate the impact of providing specialty psychiatry (PS) pharmacist intervention in identifying and resolving drug-related problems (DRPs) among children with ASD associated with disruptive behaviours...

Neuropsychiatric symptoms (NPS) in Alzheimer's disease (AD) are associated with significant negative outcomes for patients and their caregivers. Agitation, one of the most distressing NPS, lacks well-established long term interventions that are both effective and safe. While nonpharmacological interventions are suggested as first-line treatment, they aren't effective in managing symptoms for every patient, resulting in pharmacological interventions for some patients. Traditionally these interventions consist of off-label use of antipsychotics, sedative/hypnotics, anxiolytics, acetylcholinesterase inhibitors, memantine, and antidepressants; where the efficacy doesn't necessarily outweigh the associated risks...

Schizophrenia is likely to be associated with immunological abnormalities. However, antipsychotics may induce immunomodulatory effects, by influencing plasma cytokines. In order to distinguish these influences, we carried out a systematic review and meta-analysis exploring the acute effect of antipsychotics on candidate cytokines plasma levels (IL-1β, IL-2, IL-6, IL-17, IFN-γ, TNF-α) among drug-naïve subjects with first episode psychosis. We searched main Electronic Databases, identifying eight studies meeting our inclusion criteria...

Dopamine receptor D2 (D2R) plays an important role in the human central nervous system and is a focal target of antipsychotic agents. The D2(High)R and D2(Low)R dimeric models previously developed by our group are used to investigate the prediction of binding affinity of the LY404,039 ligand and its binding mechanism within the catalytic domain. The computational data obtained using molecular dynamics simulations fit well with the experimental results. The calculated binding affinities of LY404,039 using MM/PBSA for the D2(High)R and D2(Low)R targets were -12...

OBJECTIVES: To assess the efficacy and tolerability of lurasidone versus other atypical antipsychotic monotherapy agents in patients with bipolar depression, using a Bayesian network meta-analysis. METHODS: Fourteen randomised clinical trials (6221 patients) of lurasidone, quetiapine (extended release and immediate release), aripiprazole, olanzapine, and ziprasidone for bipolar depression were included. Efficacy assessments included change in the Montgomery-Åsberg Depression Rating Scale (MADRS), rates of response (≥50% improvement in MADRS) and remission (MADRS ≤12 at study endpoint), and change in the Clinical Global Impressions-Bipolar Disorder-Severity (CGI-BP-S) scale...

Many atypical antipsychotic drugs currently prescribed for the treatment of schizophrenia have limited brain penetration due to the efflux activity of ATP-binding cassette (ABC) transporters at the blood-brain barrier (BBB), including P-glycoprotein (P-gp) and ABCG2. Herein, we describe the design and synthesis of the first class of homodimeric prodrug dual inhibitors of P-gp and ABCG2. These inhibitors are based on the structure of the atypical antipsychotic drug paliperidone (Pal), a transport substrate for both transporters...

Chlorpromazine is a low potency "typical" antipsychotic agent used to treat schizophrenia. It continues to be prescribed frequently in India owing to its lower cost. There have been previous reports of ocular adverse effects with prolonged use of chlorpromazine. We report three patients who developed corneal and lenticular opacities secondary to prolonged chlorpromazine use leading to visual impairment. Early detection of ocular deposits and switching over to risperidone from chlorpromazine helped in the reversal of chlorpromazine- induced ocular side effects in one of them...

The aging world population had led to an increase in the prevalence of Alzheimer's disease (AD). The drugs used to slow down the onset of AD, galantamine, donepezil, rivastigmine and memantine, are generally well-tolerated. However, drug interactions between these drugs and other drugs are an important aspect of patient safety that should be borne in mind, particularly given the high burden of polypharmacy in the elderly. The aim of this review is to provide an updated review of clinically significant drug-drug interactions concerning drugs approved for AD...

OBJECTIVE: Anxiety disorders are among the most frequent psychiatric disorders. Current treatment guidelines recommend antidepressants, the calcium modulator gabapentin, and benzodiazepines as pharmacological treatments. However, delayed onset of action precludes the use of antidepressants as an acute treatment, while benzodiazepines can be recommended only as an emergency treatment due to their inherent risk of dependence. Therefore, an alternative pharmacological agent with acute efficacy is needed...

Hallucinogens evoke sensory, perceptual, affective, and cognitive effects that may be useful to understand the neurobiological basis of mood and psychotic disorders. The present chapter reviews preclinical research carried out in recent years in order to better understand the action of psychotomimetic agents such as the noncompetitive NMDA receptor (NMDA-R) antagonists and serotonergic hallucinogens. Our studies have focused on the mechanisms through which these agents alter cortical activity. Noncompetitive NMDA-R antagonists, such as phencyclidine (PCP) and MK-801 (dizocilpine), as well as the serotonergic hallucinogens DOI and 5-MeO-DMT, produce similar effects on cellular and population activity in prefrontal cortex (PFC); these effects include alterations of pyramidal neuron discharge (with an overall increase in firing), as well as a marked attenuation of the low frequency oscillations (0...

Neuropsychiatric disorders such as schizophrenia are associated with cognitive impairment, including learning, memory and attention deficits. Antipsychotic drugs are limited in their efficacy to improve cognition; therefore, new therapeutic agents are required. Cannabidiol (CBD), the non-intoxicating component of cannabis, has anti-inflammatory, neuroprotective and antipsychotic-like properties, however, its ability to improve the cognitive deficits of schizophrenia remains unclear. Using a prenatal infection model, we examined the effect of chronic CBD treatment on cognition and social interaction...

The metabotropic glutamate receptor 2 (mGlu2) plays an important role in the presynaptic control of glutamate release and several mGlu2 positive allosteric modulators (PAMs) have been under assessment for their potential as antipsychotics. The binding mode of mGlu2 PAMs is better characterized in functional terms while few data are available on the relationship between allosteric and orthosteric binding sites. Pharmacological studies characterizing binding and effects of two different chemical series of mGlu2 PAMs are therefore carried out here using the radiolabeled mGlu2 agonist (3)[H]-LY354740 and mGlu2 PAM (3)[H]-2,2,2-TEMPS...
