Sexual dysfunction, a common side effect of antipsychotic medications, may be partly caused by dopamine antagonism and elevation of prolactin. In QUALIFY, a randomized study, aripiprazole once-monthly 400 mg (AOM 400), a dopamine D2 receptor partial agonist, showed noninferiority and subsequent superiority versus paliperidone palmitate (PP), a dopamine D2 receptor antagonist, on the Heinrichs-Carpenter Quality-of-Life Scale (QLS) in patients with schizophrenia aged 18-60 years. Sexual dysfunction (Arizona Sexual Experience Scale) and serum prolactin levels were also assessed...

Polypharmacy is common in psychiatry. Usage of cognitive enhancers is increasing in the psychiatric population. Many clinicians are not familiar with these new psychoactive compounds. This paper reviews the potential drug-drug interactions when these cognitive enhancers are used together with psychotropic drugs and their confounding effects on diagnosis and clinical management.

Tachycardia is a known adverse effect during clozapine treatment. However, prevalence reported differs widely between studies and hitherto there are no studies comparing clozapine-treated patients with a similar control group. The present study was carried out to assess the prevalence of tachycardia in patients treated with clozapine and antipsychotic long-acting injections (LAI). Data on heart rate (HR), concomitant medication, and relevant anthropometric and laboratory measurements were collected for all clozapine-treated patients (n=174) in a defined catchment area and compared with data on patients treated with LAI (n=87)...

There has only been limited research into the predictors of readmission in bipolar disorder. We carried out a 1-year follow-up of patients discharged from a single mental health unit following admission for treatment of an acute bipolar episode. Of 519 patients followed up for 1 year, 167 (32.2%) were readmitted. There was no association between readmission and any drug regimen. Prescription of antidepressants at discharge was not associated with increased risk of readmission [odds ratio (OR): 0.99, 95% confidence interval (CI): 0...

Studies have examined the differences in sociodemographic/clinical characteristics between patients on long-acting injectable (LAI) versus oral medications. However, most studies did not focus specifically on patients for whom LAIs would clearly be indicated. We performed a chart review of patients with schizophrenia or schizoaffective disorder. Patients were categorized as having an 'indication for an LAI' or not on the basis of their adherence history. Patients for whom an LAI was indicated and prescribed on discharge were then compared with similar patients for whom an LAI was not prescribed...

The aim is to determine whether serum drug concentrations obtained from the neonate's umbilical cord can be used as a prognostic factor for admission to the neonatology ward and the occurrence of withdrawal symptoms. A retrospective observational monocenter cohort study was carried out among pregnant women using psychotropic drugs and their baby. Binary logistic regression was used for the multivariate analysis. Of the 186 neonates included, 22.6% (n=42) were admitted to the neonatology ward, 6.5% (n=12) because of withdrawal...

Comorbidity between borderline personality disorder (BPD) and alcohol use disorder (AUD) is high and relevant as alcohol consumption seems to worsen BPD symptomatology. One of the newest treatments for AUD, nalmefene, may be useful to improve BPD symptoms not only indirectly by reducing alcohol consumption but also directly by acting on the opioid system as this system has been related to specific BPD symptoms. This open-label study aimed at evaluating the efficacy of an 8-week nalmefene treatment in reducing alcohol consumption in individuals with BPD and comorbid AUD...

Acute extrapyramidal symptoms (EPS) occur frequently in schizophrenia, mostly caused by antidopaminergic substances. There have been no published reports on the impact of acute EPS on cerebral blood flow (CBF) or related measures. In the following study, we examined schizophrenic patients with and without EPS during a planning task and measurements of CBF velocity. Sixteen patients with chronic schizophrenia and 16 healthy participants performed a planning paradigm during bilateral functional transcranial Doppler sonography of the middle cerebral arteries...

Approximately 40% of patients treated for depression do not respond to a trial of an antidepressant. The aim of the proposed study was to evaluate the efficacy and safety of switching to vilazodone in patients with major depressive disorder who are unresponsive or only partially responsive to a trial of citalopram. Seventy-nine adults with major depressive disorder were enrolled in an open-label study of citalopram (20 mg/day) for 6 weeks. Those still symptomatic after 6-weeks of citalopram were randomly assigned to either a higher dose of citalopram (40 mg/day) or to vilazodone in a double-blind trial for 6 weeks...

The aim of this study was to explore the significant predictors associated with electroconvulsive therapy (ECT) outcome for patients with major depressive disorder. Major depressive disorder inpatients (N=130) requiring ECT were recruited from a major psychiatric center in South Taiwan. ECT was generally performed for a maximum of 12 sessions. Symptom severity was assessed using the 17-item Hamilton Depression Rating Scale (HAMD-17) and Clinical Global Impression of Severity (CGI-S) before ECT, after every three ECT sessions, and after the last ECT...

The aim of our study was to investigate the risk of any, ischemic, and hemorrhagic stroke associated with incident benzodiazepine and related drug (BZDR) use among community-dwelling individuals with Alzheimer's disease (AD). Data from the MEDALZ cohort including all community-dwelling persons newly diagnosed with AD between 2005 and 2011 in Finland were utilized. Incident BZDR users were identified with a 1-year washout period for previous use. Persons with a previous stroke were excluded, resulting in a final study sample of 45 050 individuals...

Although the effectiveness of clozapine (CLZ) for patients with treatment-resistant schizophrenia (TRS) has been well established, its active mechanism has not been completely clarified. Several clinical studies showed that neuroleptic-induced dopamine supersensitivity psychosis (DSP) could be involved in the etiology of TRS. We preliminarily explored the possible beneficial effect of CLZ for dopamine supersensitivity schizophrenia. The present study is a case series. We followed 15 patients with DSP for about 2...

The aim of this study was to determine whether the incidence of pneumonia in patients taking clozapine was more frequent compared with those taking risperidone or no atypical antipsychotics at all before admission to a tertiary care medical center. This was a retrospective, case-matched study of 465 general medicine patients over a 25 month period from 1 July 2010 to 31 July 2012. Detailed electronic medical records were analyzed to explore the association between the use of two atypical antipsychotics and incidence of pneumonia...

We investigated the effects of simvastatin adjunctive therapy on the negative symptoms of schizophrenia. In this double-blind trial, inpatients with chronic schizophrenia were clinically stabilized on a constant dose of risperidone for at least 4 weeks before the study and were then randomized to receive risperidone (4-6 mg/day) plus either simvastatin (40 mg/day) (n=33) or placebo (n=33) for 8 weeks. The Positive and Negative Syndrome Scale was used to measure the negative, positive, and general symptoms of schizophrenia at baseline and every 2 weeks...

Populations using herbs and herbal preparations are widespread and growing. As many herbal ingredients exert actions on psychotropic drug targets, psychiatrists should be well informed and aware of potential drug-drug interactions in clinical practice. Reliable and clinically useful information in this area, however, is fragmented, if not deficient. This paper reviewed the clinical aspects of herb-drug interactions, focusing in particular on the monoamine oxidase enzyme and P450 cytochrome enzyme-inhibitory properties of herbs and their potential interference with psychotropic drug actions and clinical judgement...

We screened 216 patients in a retrospective observational investigator-initiated study, of whom 45.37% patients (n=98) were retained after the inclusion criteria were applied. These patients had been prescribed paliperidone palmitate long-acting injection (PPLAI) with diagnoses of schizophrenia, schizoaffective disorder and bipolar affective disorder. We investigated whether PPLAI has an effect on the frequency and length of admissions to mental health inpatient units, the number of contacts with Crisis Resolution Home Treatment Teams (CRHTT) and frequency of home visits by the CRHTT per patient, over 6 years, split using a 'mirror image' method...

Performance-based cognitive data were collected using the Cognitive Drug Research System in a study of levomilnacipran extended-release (ER) 40-120 mg/day (NCT01034462) in adults with major depressive disorder. These data were analyzed post-hoc to explore the relationship between cognitive measures, depression symptoms (Montgomery-Åsberg Depression Rating Scale, MADRS), and self-reported psychosocial functioning (Sheehan Disability Scale; SDS). Changes from baseline were analyzed in the intent-to-treat population and subgroups with impaired attention, as indicated by baseline Cognitive Drug Research System scores for Power of Attention and Continuity of Attention...

Trichotillomania is characterized by repetitive pulling that causes noticeable hair loss. Data on the pharmacological treatment of trichotillomania are limited, with no clear first-line agent. The aim of the current study was to determine the efficacy and tolerability of inositol in adults with trichotillomania. A total of 38 individuals (35 women; mean age: 28.9±11.4) with trichotillomania entered a 10-week, double-blind, placebo-controlled trial to evaluate the safety and efficacy of inositol (dosing ranging from 6 to 18 g/day)...

Patients with chronic schizophrenia-related disorders are at a heightened risk of developing cardiovascular disease. The presence and interpretation of cerebral vascular lesions in neuroimaging tests in these patients represents a common clinical challenge. Nevertheless, the literature on cerebrovascular disease in this population is scarce and contradictory. The aim of this study was to analyse the relationship between schizophrenia-related disorders and cerebrovascular morbidity. A case-control study compared cerebrovascular morbidity in a group of patients with schizophrenia-related disorder versus a group of patients with another severe mental illness...

Although a percentage of patients report cognitive side-effects when taking lithium, it can be difficult to determine from the literature whether any cognitive changes reflect lithium itself, the lithium serum level, residual mood symptoms, the underlying nature of bipolar disorder, or biological alterations such as hypothyroidism. This review was carried out to synthesize and evaluate relevant literature examining any cognitive impact of lithium in those with bipolar disorder. The effect of lithium in those with bipolar disorder was examined across the cognitive domains of attention, psychomotor speed, processing speed, working memory, intellectual functioning, verbal memory, visual memory, and executive functioning by reviewing the published empirical literature...
