A novel molecular imprinting polymer (MIP) was prepared by bulk polymerization using sulpiride as the template molecule, itaconic acid (ITA) as the functional monomer and ethylene glycol dimethacrylate (EGDMA) as the crosslinker. The formation of the MIP was determined as the molar ratio of sulpiride-ITA-EGDMA of 1:4:15 by single-factor experiments. The MIP showed good adsorption property with imprinting factor α of 5.36 and maximum adsorption capacity of 61.13 μmol/g, and was characterized by scanning electron microscopy (SEM), Fourier-transform infrared spectroscopy (FT-IR) and surface area analysis...

Little is known about hyperprolactinaemia (HPL) in first episode psychosis (FEP) patients. We investigated longitudinal changes in serum prolactin in FEP, and the relationship between HPL, and antipsychotic medication and stress. Serum prolactin was recorded in FEP patients at recruitment and again, 3 and 12months later. HPL was defined as a serum prolactin level >410mIU/L (~19.3ng/ml) for males, and a serum prolactin level >510mIU/L (~24.1ng/ml) for females. From a total of 174 people with serum prolactin measurements at study recruitment, 43% (n=74) had HPL, whilst 27% (n=21/78) and 27% (n=26/95) had HPL at 3 and 12months respectively...

BACKGROUND: The first episode of schizophrenia is a pivotal phase of this debilitating illness. Which drug to use remains controversial without a summary of all direct or indirect comparisons of drugs. We did a systematic review with pairwise and network meta-analyses of efficacy and tolerability. METHODS: We searched MEDLINE, Embase, PsycINFO, Cochrane Library, PubMed, Biosis, and ClinicalTrials.gov for randomised controlled trials of antipsychotics for the acute treatment of first-episode schizophrenia, published up to Nov 17, 2016...

Since the discovery of chlorpromazine (CPZ) in 1952, first-generation antipsychotics (FGAs) have revolutionized psychiatric care in terms of facilitating discharge from hospital and enabling large numbers of patients with severe mental illness (SMI) to be treated in the community. Second-generation antipsychotics (SGAs) ushered in a progressive shift from the paternalistic management of SMI symptoms to a patient-centered approach, which emphasized targets important to patients - psychosocial functioning, quality of life, and recovery...

Ying Liang, Xin Yu
BACKGROUND: Effective management strategies for the negative symptoms of schizophrenia remain an unmet need, and data on the use of antipsychotics in this population are scarce, particularly in Chinese patients. Therefore, we investigated amisulpride for the treatment of Chinese patients with predominantly negative symptoms of schizophrenia. METHODS: This post hoc subanalysis of the prospective Effectiveness and Safety of Amisulpride in Chinese Patients with Schizophrenia (ESCAPE) study included adult Chinese patients with an International Classification of Diseases-10 diagnosis of schizophrenia and predominantly negative symptoms, who received amisulpride for 8 weeks...

We recently investigated neuromodulatory effects of the noradrenergic agent reboxetine and the dopamine receptor affine amisulpride in healthy subjects on dynamic erotic stimulus processing. Whereas amisulpride left sexual functions and neural activations unimpaired, we observed detrimental activations under reboxetine within the caudate nucleus corresponding to motivational components of sexual behavior. However, broadly impaired subjective sexual functioning under reboxetine suggested effects on further neural components...

Hypochondriasis (HYPO), an obsessive-compulsive spectrum disorder, is frequent in patients with schizophrenia (SCH) (20%), especially among those treated with clozapine (36.7%). Treatment options for OCS/OCD in patients under clozapine (CLZ) include combining clozapine with amisulpride/aripiprazole or a mood stabilizer, augmenting clozapine with a serotoninergic reuptake inhibitor, adding cognitive behavioural therapy, and gradually reducing dosage. No treatments have been proposed for HYPO in patients using clozapine so we examine these options in 2 cases and report the results...

BACKGROUND: The effects of antipsychotic drug withdrawal have been inadequately studied. Case reports have described dyskinesia occurring in patients with several antipsychotics withdrawn, but studies on amisulpride withdrawal dyskinesia are lacking. CASE PRESENTATION: A 63-year-old man, who was diagnosed with schizophrenia at age 49, received amisulpride treatment since age 62. The dosage of amisulpride was reduced from 200 to 50 mg/day because of occurrence of akathisia during one admission...

Impairments in metacognition, the ability to accurately report one's performance, are common in patients with psychiatric disorders, where a putative neuromodulatory dysregulation provides the rationale for pharmacological interventions. Previously, we have shown how unexpected arousal modulates metacognition (Allen et al., 2016). Here, we report a double-blind, placebo-controlled, study that examined specific effects of noradrenaline and dopamine on both metacognition and perceptual decision making. Signal theoretic analysis of a global motion discrimination task with adaptive performance staircasing revealed that noradrenergic blockade (40 mg propranolol) significantly increased metacognitive performance (type-II area under the curve, AUROC2), but had no impact on perceptual decision making performance...

INTRODUCTION: Second-generation antipsychotics show significant interpatient variability in treatment response and side-effect profiles, and the majority of patients with schizophrenia require multiple treatment changes. This subgroup analysis of the ESCAPE study evaluated the efficacy and safety of amisulpride in Chinese patients with schizophrenia who switched from risperidone or olanzapine. METHODS: ESCAPE was a prospective, open-label, multicenter, single-arm Phase IV study in which Chinese patients with an ICD-10 diagnosis of schizophrenia received amisulpride for 8 weeks...

Deficits in information processing and cognition are among the most robust findings in schizophrenia patients. Previous efforts to translate group-level deficits into clinically relevant and individualized information have, however, been non-successful, which is possibly explained by biologically different disease subgroups. We applied machine learning algorithms on measures of electrophysiology and cognition to identify potential subgroups of schizophrenia. Next, we explored subgroup differences regarding treatment response...

Neuroleptic drugs are widely applied in effective treatment of schizophrenia and related disorders. The lipophilic character of neuroleptics means that they tend to accumulate in the lipid membranes, impacting their functioning and processing. In this paper, the effect of four drugs, namely, thioridazine, olanzapine, sulpiride, and amisulpride, on neutral and negatively charged lipid bilayers was examined. The interaction of neuroleptics with lipids and the subsequent changes in the membrane physical properties was assessed using several complementary biophysical approaches (isothermal titration calorimetry, electron paramagnetic resonance spectroscopy, dynamic light scattering, and ζ potential measurements)...
