Abstract
OBJECTIVE Despite the high prevalence of anxiety in schizophrenia, no established guideline exists for the management of these symptoms. We aimed to synthesize evidence on the effect of second-generation antipsychotics (SGAs) on anxiety in patients with schizophrenia. METHODS We systematically searched Medline, Embase, PsycInfo, Web of Science, PubMed, and Cochrane library to identify randomized controlled trials of SGAs that reporting anxiety measures in schizophrenia. The search was limited to English-language articles published before February 2024. Data were pooled using a random-effects model. RESULTS Among 48 eligible studies, 29 (n = 7712) were included in the meta-analyses comparing SGAs to placebo, haloperidol, or another SGAs for their effect on anxiety/depression. SGAs had a small effect on anxiety/depression versus placebo (SMD = -0.28 (95 % CI [-0.34, -0.21], p < .00001, I2 = 47 %, n = 5576)) associated with efficacy for positive (z = 5.679, p < .001) and negative symptoms (z = 4.490, p < .001). Furthermore, SGAs were superior to haloperidol (SMD = -0.44, 95 % CI [-0.75, -0.13], p = .005, n = 1068) with substantial study-level heterogeneity (I2 = 85 %). Excluding one study of quetiapine in first-episode patients (SMD = -3.05, n = 73), SGAs showed a small effect on anxiety/depression versus haloperidol without heterogeneity (SMD = -0.23, 95 % CI [-0.35, -0.12], p = 01; I2 = %0). Risperidone's effect on anxiety/depression was comparable to olanzapine (SMD = -0.02, 95 % CI [-0.24,0.20], p = .87, I2 = 45 %, n = 753) and amisulpride (SMD = 0.27, 95 % CI [-1.08,0.61], p = .13, I2 = 50 %, n = 315). CONCLUSION While SGAs showed a small effect on anxiety/depression, the findings are inconclusive due to scarcity of research on comorbid anxiety in schizophrenia, heterogeneity of anxiety symptoms, and the scales used to measure anxiety. Further studies employing specific anxiety scales are required to explore antipsychotics, considering their receptor affinity and augmentation with serotonin/norepinephrine reuptake inhibitors or benzodiazepines for managing anxiety in schizophrenia.

Systematic review and meta-analysis. Front Psychiatry 2023; 14:1189768. [PMID: 37441144 PMCID: PMC10333591 DOI: 10.3389/fpsyt.2023.1189768] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/20/2023] [Accepted: 05/31/2023] [Indexed: 07/15/2023] Open
Abstract
Introduction Our objective was to conduct a systematic review and meta-analysis of adverse effects on sleep in patients with schizophrenia receiving antipsychotic treatment. Methods A systematic search was performed in PubMed, Cochrane Central, Embase, Toxline, Ebsco, Virtual Health Library, Web of Science, SpringerLink, and in Database of abstracts of Reviews of Effects of Randomized Clinical Trials to identify eligible studies published from January 1990 to October 2021. The methodological quality of the studies was evaluated using the CONSORT list, and the Cochrane bias tool. Network meta-analysis was performed using the Bayesian random-effects model, with multivariate meta-regression to assess the association of interest. Results 87 randomized clinical trials were identified that met the inclusion criteria, and 70 articles were included in the network meta-analysis. Regarding the methodological quality of the studies, 47 had a low or moderate bias risk. The most common adverse effects on sleep reported in the studies were insomnia, somnolence, and sedation. The results of the network meta-analysis showed that ziprasidone was associated with an increased risk of insomnia (OR, 1.56; 95% credible interval CrI, 1.18-2.06). Several of the included antipsychotics were associated with a significantly increased risk of somnolence; haloperidol (OR, 1.90; 95% CrI, 1.12-3.22), lurasidone (OR, 2.25; 95% CrI, 1.28-3.97) and ziprasidone (OR, 1.79; 95% CrI, 1.06-3.02) had the narrowest confidence intervals. In addition, perphenazine (OR, 5.33; 95% CrI, 1.92-14.83), haloperidol (OR, 2.61; 95% CrI, 1.14-5.99), and risperidone (OR, 2.41; 95% CrI, 1.21-4.80) were associated with an increased risk of sedation compared with placebo, and other antipsychotics did not differ. According to the SUCRAs for insomnia, chlorpromazine was ranked as the lowest risk of insomnia (57%), followed by clozapine (20%), while flupentixol (26 %) and perospirone (22.5%) were associated with a lower risk of somnolence. On the other hand, amisulpride (89.9%) was the safest option to reduce the risk of sedation. Discussion Insomnia, sedation, and somnolence were the most frequent adverse effects on sleep among the different antipsychotics administered. The evidence shows that chlorpromazine, clozapine, flupentixol, perospirone, and amisulpride had favorable safety profiles. In contrast, ziprasidone, perphenazine, haloperidol, and risperidone were the least safe for sleep.

Abstract
BACKGROUND We examined the efficacy and safety of using antipsychotic medication for schizophrenia using only randomized trials of antipsychotic for schizophrenia conducted in Japan to avoid the biological and environmental heterogeneities caused by pooling data from various races and ethnicities. METHODS We searched for eligible studies on Embase, PubMed, and CENTRAL. Primary outcomes were improvement in Positive and Negative Syndrome Scale total score (PANSS-T) and all-cause discontinuation. Other outcomes were improvement in PANSS subscale scores, discontinuation due to adverse events or inefficacy, and the incidence of 16 adverse events. RESULTS We calculated mean difference or risk ratios and 95% credible intervals. We identified 34 RCTs (6798 patients; mean study duration, 9.0 ± 4.24 weeks; proportion of male patients, 53.7%; mean age, 43.3 years). Besides placebo, studies included aripiprazole, asenapine, blonanserin, blonanserin-patch, brexpiprazole, clocapramine (no PANSS data), clozapine (no PANSS data), haloperidol, lurasidone, mosapramine, olanzapine, paliperidone, perospirone, quetiapine, and risperidone. Efficacy and safety profiles differed for antipsychotics used with schizophrenia in Japanese patients. All active treatments other than haloperidol and quetiapine outperformed placebo to improve PANSS-T. Asenapine, olanzapine, paliperidone, and risperidone outperformed placebo for all-cause discontinuation. Asenapine, blonanserin, blonanserin-patch, haloperidol, lurasidone, mosapramine, olanzapine, paliperidone, and risperidone outperformed placebo to improve PANSS positive subscale scores. Aripiprazole, asenapine, blonanserin, blonanserin-patch, brexpiprazole, lurasidone, olanzapine, paliperidone, perospirone, and risperidone outperformed placebo to improve PANSS negative subscale scores. The confidence in evidence of most outcomes was low or very low. CONCLUSION Our results are similar to those of previous network meta-analysis involving various races and ethnicities.

Abstract
BACKGROUND AND OBJECTIVES Second-generation antipsychotics (SGAs) for schizophrenia show different risk profiles, whose evidence has been evaluated through comparative reviews on randomized controlled trials (RCTs) and observational studies. METHODS We performed a systematic review and meta-analysis of weight gains, metabolic and cardiovascular side effects of SGAs, relying on both RCTs and observational studies, by comparing variations between the start of treatment and the end of follow-up. The systematic review refers to papers published from June 2009 to November 2020. PRISMA criteria were followed. No restrictions on heterogeneity level have been considered for meta-analysis. A test for the summary effect measure and heterogeneity (I2 metric) was used. RESULTS Seventy-nine papers were selected from 3076 studies (61% RCTs, 39% observational studies). Olanzapine and risperidone reported the greatest weight gain and olanzapine the largest BMI increase. Paliperidone showed the highest increase in total cholesterol, but is the only drug reporting an increase in the HDL cholesterol. Quetiapine XR showed the highest decrease in fasting glucose. Lurasidone showed the lowest increase in body weight and a reduction in BMI and was also the only treatment reporting a decrease in total cholesterol and triglycerides. The highest increase in systolic and diastolic blood pressure was reported by quetiapine XR. CONCLUSIONS Despite some limitations (differences in the mean dosages per patient and other side effects not included) this paper provides the first complete meta-analysis on SGAs in variations on metabolic risk profile between start of treatment and end of follow-up, with useful results for clinical practice and possibly for future economic evaluation studies.

Abstract
BACKGROUND The relative efficacy and tolerability of antipsychotics for schizophrenia are considerably well studied. This study aimed to examine whether previous findings could be replicated in a genetically distinct and homogenous group (ie, Japanese patients with schizophrenia) and whether previous findings could be extended to a broader range of antipsychotics with previously unclear relative efficacy and tolerability. METHODS Bayesian network meta-analysis was performed in which randomized trials comparing any of the following interventions were included: second-generation antipsychotics, haloperidol, or placebo. The primary outcomes for efficacy and acceptability were the response rate and all-cause discontinuation. The secondary outcomes included the improvement of Positive and Negative Syndrome Scale scores, discontinuation because of adverse events, and individual adverse events. RESULTS Eighteen relevant studies were identified (total n=3,446; aripiprazole =267, blonanserin =285, clozapine =47, clocapramine =295, haloperidol =857, mosapramine =493, olanzapine =179, paliperidone =136, perospirone =146, placebo =138, quetiapine =212, and risperidone =338; mean study duration =8.33±1.41 weeks). In primary outcomes, olanzapine and paliperidone showed efficacy than placebo, and olanzapine and paliperidone showed superior acceptability compared with placebo. There were differences in the incidences of individual adverse events (the best antipsychotic: extrapyramidal symptoms = olanzapine, hyperprolactinemia- related symptoms = quetiapine, sedation = paliperidone, and weight change = blonanserin) among antipsychotics. CONCLUSION Although the current analysis exclusively included Japanese patients with schizophrenia, no remarkable differences were observed in efficacy and safety compared with previous meta-analyses. Diverse hierarchies in safety outcomes also support the implication that individual risk expectations for adverse events can guide clinical decisions. However, the sample size was relatively limited. Additional efficacy and safety data are required to fully obtain a conclusive understanding.

Abstract
BACKGROUND Individual differences in serotonin 7 receptor (5-HT7R) may result in variable response to antipsychotics with 5-HT7R antagonism. This study investigated the relationship between single nucleotide polymorphisms (SNPs) in the 5-HT7R gene (HTR7) and the efficacy of second-generation antipsychotic drugs with a high affinity for this receptor in Japanese schizophrenia. METHODS Perospirone or aripiprazole was administered to 100 patients with schizophrenia in a randomized controlled study. All patients were genotyped for three candidate SNPs (rs12412496, rs7916403, and rs1935349). Patient improvement on the Positive and Negative Syndrome Scale (PANSS) total score at 12 weeks was assessed as the primary outcome. PANSS 5-factor scores were investigated as the secondary outcome. RESULTS Improvement on the PANSS total score and genetic polymorphisms showed no correlation. The rs12412496-rs7916403-rs1935349 A-T-A haplotype was correlated with worse improvement in the cognition score (haplotype frequency: 0.285, p = 0.046, permuted p = 0.043). CONCLUSION Our results show that HTR7 variants are not related to the overall improvement in schizophrenia symptoms.

Abstract
Few data are available on the efficacy and safety of antipsychotics with different dopamine D2 receptor (D2-R)-binding properties in drug-naïve and non-drug-naïve schizophrenia. Thus, we aimed to assess whether antipsychotic medication history influences efficacy and tolerability in schizophrenia, based on a randomized controlled study of antipsychotics with mechanisms involving either full antagonism or partial agonism of D2-R. Patients with schizophrenia were recruited and given perospirone or aripiprazole in a 12-week, flexible-dose, open-label, randomized controlled study. Data were analyzed after dividing the patients into antipsychotic-naïve and antipsychotic-treated group according to antipsychotic medication histories. Efficacy and safety were evaluated using the Positive and Negative Syndrome Scale (PANSS), the Drug-Induced Extrapyramidal Symptoms Scale, and the Barnes Akathisia Rating Scale. In patients receiving perospirone, the antipsychotic-naïve group (n = 22) showed greater symptom improvement than that shown by the antipsychotic-treated group (n = 29), as assessed by efficacy evaluation scales such as the PANSS total, positive, and excited component score (p = .006, p < .001, p = .003, respectively). In patients receiving aripiprazole, however, there was no significant difference in efficacy between the antipsychotic-naïve (n = 18) and antipsychotic-treated (n = 31) groups. No significant intra-group or inter-group difference was noted with respect to any of the tolerability-related parameters assessed. The present study data support the hypothesis that antipsychotic medication history may influence efficacy in patients who receive a D2-R full antagonist but not a D2-R partial agonist.

Abstract
Individual differences in serotonin 1A (5-HT1A) receptor may result in variable response to antipsychotics with 5-HT1A receptor partial agonism. We investigated the relationship between 5-HT1A receptor gene (HTR1A) single nucleotide polymorphisms (SNPs) and efficacy of antipsychotics with 5-HT1A receptor partial agonism in Japanese patients with schizophrenia. Perospirone or aripiprazole was administered to 100 patients with schizophrenia in a randomized controlled study. Candidate SNPs were rs6295 (which affects HTR1A expression and function), rs1364043, rs878567, and rs10042486. Efficacy at week 12 of treatment was evaluated using the Positive and Negative Syndrome Scale (PANSS) 5-factor subscales (excitement/hostility, depression/anxiety, cognition, positive, and negative). Rs1364043 T allele was correlated with the percent change in the PANSS 5-factor negative score (P < 0.01). Haplotype analysis showed that the rs10042486-rs6295-rs1364043 T-C-G haplotype was correlated with worse negative score improvement (haplotype frequency, 0.675; P = 0.014), and the relatively rare T-G-T haplotype correlated with better efficacy (haplotype frequency, 0.05; P = 0.031). This is the first study to show that rs10042486-rs6295-rs1364043 HTR1A variants may be correlated with the improvement of the PANSS 5-factor negative score during treatment with 5-HT1A partial agonist antipsychotics. Studies with larger sample sizes and in different ethnic groups are warranted.

Abstract
BACKGROUND We conducted a systematic review and meta-analysis of randomized controlled trials comparing aripiprazole with pooled antipsychotics in Japanese patients with schizophrenia. METHODS We performed a literature search of data published in PubMed(®), the Cochrane Library database, the Japan Medical Abstracts Society, and PsycINFO(®) up to January 5, 2014. The odds ratio (OR), number-needed-to-harm (NNH), and standardized mean difference (SMD) based on a random effects model were calculated. RESULTS We identified five relevant studies (seven comparisons, n=684; one comparison each for haloperidol [n=243], mosapramine [n=238], olanzapine [n=39], quetiapine [n=42], perospirone [n=100], and two comparisons for risperidone [n=66]). There were no significant differences in the Positive and Negative Syndrome Scale (PANSS) total, negative, and general scores (SMD=0.10, SMD=-0.09, SMD=0.10, respectively); discontinuation rate associated with all causes (OR=1.35); or side effects (OR=1.03) between aripiprazole and the pooled antipsychotics. Aripiprazole was inferior to the pooled antipsychotics in PANSS positive subscale scores (SMD=0.17) and discontinuation because of inefficacy (OR=2.21, NNH=11). However, aripiprazole had fewer side effects compared with the pooled antipsychotics (OR=0.21, NNH=20 for one or more side effects), including fatigue (OR=0.22, NNH=8), hyperprolactinemia (OR=0.00, NNH=1), extrapyramidal symptoms (OR=0.46, NNH=6), and weight gain (OR=0.36, NNH=7). Moreover, aripiprazole was associated with lower total cholesterol (SMD=-0.20) and triglyceride (SMD=-0.17) levels and body weight (SMD=-0.20) compared with the pooled antipsychotics. CONCLUSION Although the discontinuation rate associated with inefficacy was higher with aripiprazole than with the pooled antipsychotics, aripiprazole was associated with a lower risk of hyperprolactinemia and metabolic and extrapyramidal symptoms compared with the pooled antipsychotics.

Abstract
Background The present study aimed to evaluate cardiometabolic risks [weight gain, blood lipid levels (total cholesterol and triglycerides), blood glucose levels, hemoglobin A1c (HbA1c) levels, and corrected QT interval (QTc) prolongation] associated with the use of blonanserin and perospirone versus other antipsychotics in the management of patients with schizophrenia. Method We conducted a systematic review and meta-analysis of patient data from randomized controlled trials comparing blonanserin or perospirone with other antipsychotics. Results In total, 4 blonanserin studies (n = 1080) were identified [vs. risperidone (2 studies, n = 508); vs. haloperidol (2 studies, n = 572)]. Blonanserin produced less weight gain compared with risperidone (weighted mean difference = −0.86, 95% confidence intervals = −1.36 to −0.36, p = 0.0008; 2 studies, 480 patients). However, no significant differences were observed in blood lipid, glucose, and HbA1c levels or QTc prolongation between blonanserin and risperidone or haloperidol. For perospirone studies, 5 studies [562 adult patients with schizophrenia randomized to perospirone (n = 256), olanzapine (n = 20), quetiapine (n = 28), risperidone (n = 53), aripiprazole (n = 49), haloperidol (n = 75), or mosapramine (n = 81)] were identified. Perospirone did not differ from other antipsychotics with regard to weight gain and total cholesterol levels. Conclusions Our results suggest that blonanserin is associated with a lower of weight gain compared with other antipsychotics. Because the number of studies was small, additional controlled clinical trials with larger number of patients are indicated.

Differential mechanisms underlie the regulation of serotonergic transmission in the dorsal and median raphe nuclei by mirtazapine: a dual probe microdialysis study.

Abstract
RATIONALE Blockade of α2 adrenoceptors and histamine H1 receptors plays important roles in the antidepressant and hypnotic effects of mirtazapine. OBJECTIVES However, it remains unclear how mirtazapine's actions at these receptors interact to affect serotonergic transmission in the dorsal (DRN) and median (MRN) raphe nuclei. METHOD Using dual-probe microdialysis, we determined the roles of α2 and H1 receptors in the effects of mirtazapine on serotonergic transmission in the DRN and MRN and their respective projection regions, the frontal (FC) and entorhinal (EC) cortices. RESULTS Mirtazapine (<30 μM) failed to alter extracellular serotonin levels when perfused alone into the raphe nuclei, but when co-perfused with a 5-HT1A receptor antagonist, mirtazapine increased serotonin levels in the DRN, MRN, FC, and EC. Serotonin levels in the DRN and FC were decreased by blockade and increased by activation of H1 receptors in the DRN. Serotonin levels in the MRN and EC were not affected by H1 agonists/antagonists perfused in the MRN. The increase in serotonin levels in the DRN and FC induced by DRN H1 receptor activation was attenuated by co-perfusion with mirtazapine. Furthermore, the increase in serotonin levels (DRN/FC) induced by DRN α2 adrenoceptor blockade was attenuated by concurrent DRN H1 blockade, whereas the increase in serotonin levels (MRN/EC) induced by MRN α2 adrenoceptor inhibition was unaffected by concurrent MRN H1 receptor blockade. CONCLUSION These results suggest that enhanced serotonergic transmission resulting from α2 adrenoceptor blockade is offset by subsequent activation of 5-HT1A receptors and, in the DRN but not MRN, H1 receptor inhibition. These pharmacological actions of mirtazapine may explain its antidepressant and hypnotic actions.

Efficacy and tolerability of perospirone in schizophrenia: a systematic review and meta-analysis of randomized controlled trials. CNS Drugs 2013; 27:731-41. [PMID: 23812802 DOI: 10.1007/s40263-013-0085-7] [Citation(s) in RCA: 13] [Impact Index Per Article: 1.2] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Indexed: 10/26/2022]
Abstract
BACKGROUND Perospirone is a second-generation antipsychotic (SGA) used only in Japan, and acts as a serotonin (5-HT)1A receptor partial agonist, 5-HT2A receptor inverse agonist, and dopamine (D)₂, D₄, and α₁-adrenergic receptor antagonist. To our knowledge, no meta-analysis addressing the efficacy and effectiveness of perospirone in schizophrenia has been published to date. OBJECTIVE The aim of the study was to identify the characteristics of perospirone by assessing the efficacy, discontinuation rate, and side effects of perospirone versus other antipsychotics in the treatment of patients with schizophrenia. METHODS Using information obtained from the PubMed, PsycINFO, Google Scholar and Cochrane Library databases without language restrictions published up to 10 June 2013, we conducted a systematic review and meta-analysis of patient data from randomized controlled trials comparing perospirone with other antipsychotic medications. Risk ratio (RR), standardized mean difference (SMD) and 95% confidence intervals were calculated. All studies used the Positive and Negative Syndrome Scale (PANSS) for the evaluation of the schizophrenia psychopathology. RESULTS The search in PubMed, Cochrane Library databases, Google Scholar and PsycINFO yielded 69 hits. We included three studies in the current meta-analysis and excluded 66 studies based on title, abstract, and full text review. Moreover, two additional studies were identified from a review article. Across the five studies (mean duration 9.6 weeks), 562 adult patients with schizophrenia were randomized to perospirone (n = 256), olanzapine (n = 20), quetiapine (n = 28), risperidone (n = 53), aripiprazole (n = 49), haloperidol (n = 75), or mosapramine (n = 81). Perospirone was not different from other pooled antipsychotics regarding reduction in PANSS negative (SMD = 0.38, p = 0.09) and general (SMD = 0.28, p = 0.06) subscale scores, and discontinuation due to any cause (RR = 1.03, p = 0.83), inefficacy (RR = 0.99, p = 0.98) and side effects (RR = 0.72, p = 0.25). However, perospirone was inferior to other pooled antipsychotics in the reduction of PANSS total scores (SMD = 0.36, p = 0.04) and positive subscale scores (SMD = 0.34, p = 0.03). Moreover, excluding the comparison of perospirone with the first-generation antipsychotic (haloperidol), perospirone was inferior to other pooled SGAs in the reduction of PANSS total scores (SMD = 0.46, p = 0.02), positive (SMD = 0.42, p = 0.03), negative (SMD = 0.52, p = 0.02) and general subscale scores (SMD = 0.37, p = 0.03). However, perospirone was superior to haloperidol in the reduction of PANSS negative subscale scores (SMD = -0.41, p = 0.01). Perospirone also had lower scores related to extrapyramidal symptoms than other pooled antipsychotics (SMD = -0.30, p = 0.01). CONCLUSIONS Our results suggest that although perospirone seems to be a well tolerated treatment, perospirone does not reduce PANSS score as much as other SGAs.
