The whole picture of psychotropics for bipolar depression (BPD) remains unclear. This review compares the differences in efficacy and safety profiles among common psychotropics for BPD. MEDLINE, EMBASE, and PsycINFO were searched for proper studies. The changes in the depressive rating scale, remission/response rates, nervous system adverse events (NSAEs), gastrointestinal adverse events (GIAEs), metabolic parameters, and prolactin were compared between medication and placebo or among medications with the Cohen's d or number needed to treat/harm. The search provided 10 psychotropics for comparison. Atypical antipsychotics (AAPs) were superior to lithium and lamotrigine at alleviating acute depressive symptoms. Lithium was more likely to induce dry mouth and nausea. Cariprazine and aripiprazole seemed to be associated with an increased risk of akathisia and upper GIAEs. Lurasidone was associated with an increased risk of developing akathisia and hyperprolactinemia. Olanzapine, olanzapine-fluoxetine combination (OFC), and quetiapine were associated with an increased risk of NSAEs, metabolic risk, dry mouth, and constipation. Cariprazine, lurasidone, OFC, or quetiapine was optimal monotherapy for BPD. Further studies are needed to assess the efficacy and safety of lamotrigine for treating BPD. Adverse events varied widely across different drug types due to variations in psychopharmacological mechanisms, dosages, titration, and ethnicities.

Meta-Analysis Review
RATIONALE
While one of the basic axioms of pharmacology postulates that there is a relationship between the concentration and effects of a drug, the value of measuring blood levels is questioned by many clinicians. This is due to the often-missing validation of therapeutic reference ranges.
OBJECTIVES
Here, we present a prototypical meta-analysis of the relationships between blood levels of aripiprazole, its target engagement in the human brain, and clinical effects and side effects in patients with schizophrenia and related disorders.
METHODS
The relevant literature was systematically searched and reviewed for aripiprazole oral and injectable formulations. Population-based concentration ranges were computed (N = 3,373) and pharmacokinetic influences investigated.
RESULTS
Fifty-three study cohorts met the eligibility criteria. Twenty-nine studies report blood level after oral, 15 after injectable formulations, and nine were positron emission tomography studies. Conflicting evidence for a relationship between concentration, efficacy, and side effects exists (assigned level of evidence low, C; and absent, D). Population-based reference ranges are well in-line with findings from neuroimaging data and individual efficacy studies. We suggest a therapeutic reference range of 120-270 ng/ml and 180-380 ng/ml, respectively, for aripiprazole and its active moiety for the treatment of schizophrenia and related disorders.
CONCLUSIONS
High interindividual variability and the influence of CYP2D6 genotypes gives a special indication for Therapeutic Drug Monitoring of oral and long-acting aripiprazole. A starting dose of 10 mg will in most patients result in effective concentrations in blood and brain. 5 mg will be sufficient for known poor metabolizers.

BACKGROUND
Our systematic review examines the effectiveness and safety of non-pharmacologic and pharmacologic interventions in preventing or treating traumatic brain injury (TBI)-related delirium in acute care.
METHODS
We searched four electronic databases (MEDLINE, EMBASE, CENTRAL/CDSR, and PsycINFO) to identify randomized controlled trials (RCTs), quasi-experimental, and observational studies. Eligible studies included adults with TBI, at least one comparator group, delirium as an outcome and took place in acute care. Two reviewers independently completed all study screening, data abstraction, and risk of bias assessment using the Cochrane risk of bias 2 tool for RCTs or risk of bias in non-randomized studies-of interventions tool for observational studies. We implemented the PROGRESS-Plus framework to describe social determinants of health (SDoH) reporting.
RESULTS
We identified 20,022 citations, reviewed 301 in full text, and included eight studies in the descriptive synthesis. The mean age of study participants ranged from 32 to 62 years. 12.5% of included studies reported SDoH. Included studies had moderate-to-high risk of bias. Studies compared reorientation programs and an intervention bundle to usual care, but these interventions were not better than usual care in treating TBI-related delirium. Individual studies found that rosuvastatin and aripiprazole were more efficacious than placebo, and dexmedetomidine was more efficacious than propofol and haloperidol for preventing TBI-related delirium. No studies reported safety as the primary outcome.
CONCLUSIONS
We identified efficacious pharmacologic interventions for preventing TBI-related delirium, but these studies were at moderate-to-high risk of bias, which limits our confidence in these findings. Future studies should incorporate safety outcomes, and a diverse study population, including older adults.

INTRODUCTION
Second-generation antipsychotics (SGAs) are frequently prescribed for the treatment of resistant anorexia nervosa. However, few clinical trials have been conducted so far and no pharmacological treatment has yet been approved by the Food and Drug Administration. The aim of this paper is to conduct a systematic scoping review exploring the effectiveness and safety of atypical antipsychotics in anorexia nervosa (AN).
METHOD
We conducted a systematic scoping review of the effectiveness and tolerability of SGAs in the management of AN. We included articles published from January 1, 2000, through September 12, 2022 from the PubMed and PsycInfo databases and a complementary manual search. We selected articles about adolescents and adults treated for AN by four SGAs (risperidone, quetiapine, aripiprazole or olanzapine). This work complies with the Preferred Reporting Items for Systematic Reviews and Meta-Analysis extension for scoping reviews (PRIMA-ScR) and was registered in the Open Science Framework (OSF) repository.
RESULTS
This review included 55 articles: 48 assessing the effectiveness of SGAs in AN and 7 focusing only on their tolerability and safety. Olanzapine is the treatment most frequently prescribed and studied with 7 randomized double-blind controlled trials. Other atypical antipsychotics have been evaluated much less often, such as aripiprazole (no randomized trials), quetiapine (two randomized controlled trials), and risperidone (one randomized controlled trial). These treatments are well tolerated with mild and transient adverse effects in this population at particular somatic risk.
DISCUSSION
Limitations prevent the studies both from reaching conclusive, reliable, robust, and reproducible results and from concluding whether or not SGAs are effective in anorexia nervosa. Nonetheless, they continue to be regularly prescribed in clinical practice. International guidelines suggest that olanzapine and aripiprazole can be interesting in severe or first-line resistant clinical situations.

Review
PURPOSE OF REVIEW
Despite clear evidence that sex differences largely impact the efficacy and tolerability of antipsychotic medication, current treatment guidelines for schizophrenia spectrum disorders (SSD) do not differentiate between men and women. This review summarizes the available evidence on strategies that may improve pharmacotherapy for women and provides evidence-based recommendations to optimize treatment for women with schizophrenia.
RECENT FINDINGS
We systematically searched PubMed and Embase for peer-reviewed studies on three topics: (1) sex differences in dose-adjusted antipsychotic serum concentrations, (2) hormonal augmentation therapy with estrogen and estrogen-like compounds to improve symptom severity, and (3) strategies to reduce antipsychotic-induced hyperprolactinemia. Based on three database studies and one RCT, we found higher dose-adjusted concentrations in women compared to men for most antipsychotics. For quetiapine, higher concentrations were specifically found in older women. Based on two recent meta-analyses, both estrogen and raloxifene improved overall symptomatology. Most consistent findings were found for raloxifene augmentation in postmenopausal women. No studies evaluated the effects of estrogenic contraceptives on symptoms. Based on two meta-analyses and one RCT, adjunctive aripiprazole was the best-studied and safest strategy for lowering antipsychotic-induced hyperprolactinemia. Evidence-based recommendations for female-specific pharmacotherapy for SSD consist of (1) female-specific dosing for antipsychotics (guided by therapeutic drug monitoring), (2) hormonal replacement with raloxifene in postmenopausal women, and (3) aripiprazole addition as best evidenced option in case of antipsychotic-induced hyperprolactinemia. Combining these strategies could reduce side effects and improve outcome of women with SSD, which should be confirmed in future longitudinal RCTs.

INTRODUCTION
The effects of antipsychotic drugs are dose-dependent, which is particularly true for their efficacy, each antipsychotic having a specific dose-response curve. This may justify individualizing doses for these agents.
AREAS COVERED
We review the pharmacokinetic profiles of seven oral antipsychotics: haloperidol, risperidone, olanzapine, clozapine, quetiapine, ziprasidone, and aripiprazole. Their main indications are psychotic and affective disorders. They are prescribed in a very large population which may have comorbidities. Hence, we analyze the impact of the latter on the pharmacokinetic profiles of these antipsychotics, focusing on renal and hepatic impairment. Reviews and clinical trials were discussed based on a systematic literature search (PubMed) ranging from 1995 to 2022.
EXPERT OPINION
Factors liable to impact antipsychotic dosage are numerous and their subsequent effects often hard to predict, due to multilevel interactions and compensatory phenomena. In clinical practice, physicians must be aware of these potential effects, but base their decisions on monitoring antipsychotic plasma levels.

Meta-Analysis Review
Antipsychotic-related prolactin changes may expose children and adolescents to severe adverse reactions (ARs) related to pubertal development and growth. We therefore aimed to assess the effects of antipsychotics on prolactin levels and associated somatic ARs in children and adolescents. We systematically searched PubMed and CENTRAL for placebo-controlled randomized trials of antipsychotics in children and adolescents aged ≤18 years, reporting prolactin levels and related ARs. We conducted a random-effect meta-analysis and assessed risk of bias version 2 (ROB2). Thirty-two randomized controlled trials with an average trial duration of 6 weeks, covering 4643 participants with an average age of 13 years and a male majority of 65.3%. Risk of bias across domains was low or unclear. The following antipsychotic compounds: aripiprazole ( = 810), asenapine ( = 506), lurasidone ( = 314), olanzapine ( = 179), paliperidone ( = 149), quetiapine ( = 381), risperidone ( = 609), and ziprasidone ( = 16) were compared with placebo ( = 1658). Compared with placebo, statistically significant higher prolactin increase occurred with risperidone (mean difference [MD] = 28.24 ng/mL), paliperidone (20.98 ng/mL), and olanzapine (11.34 ng/mL). Aripiprazole significantly decreased prolactin (MD = -4.91 ng/mL), whereas quetiapine, lurasidone, and asenapine were not associated with significantly different prolactin levels than placebo. Our results on ziprasidone are based on a single study, making it insufficient to draw strong conclusions. On average, 20.8% of patients treated with antipsychotic developed levels of prolactin that were too high (hyperprolactinemia), whereas only 1.03% of patients reported prolactin-related ARs. Data were highly limited for long-term effects. In children and adolescents, risperidone, paliperidone, and olanzapine are associated with significant prolactin increase, whereas aripiprazole is associated with significant decrease. Despite the significant changes in prolactin level, few ARs were reported. Study protocol on PROSPERO: CRD42018116451.

Meta-Analysis
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.

Meta-Analysis
BACKGROUND
Antipsychotics are widely used in the treatment of major depressive disorder (MDD), but there has been no comprehensive meta-analytic assessment that examined their use as monotherapy and adjunctive therapy.
METHODS
A systematic review and a meta-analysis were conducted on randomized placebo-controlled trials (RCTs) that reported on the efficacy and safety/tolerability of antipsychotics for the treatment of adults with MDD. Data of both monotherapy and adjunctive antipsychotic use were extracted, but analyzed separately using a random-effects model. Co-primary outcomes were study-defined-treatment response and intolerability-related discontinuation. We also illustrated the risk/benefit balance of antipsychotics for MDD, using two-dimensional graphs representing the primary efficacy and safety/tolerability outcome. Secondary outcomes included psychopathology, remission, all-cause-discontinuation, inefficacy-related discontinuation, and adverse events.
RESULTS
Forty-five RCTs with 12 724 patients were included in the analysis. In monotherapy (studies = 13, = 4375), amisulpride [1.99 (1.55-2.55)], sulpiride [1.50 (1.03-2.17)], and quetiapine [1.48 (1.23-1.78)] were significantly superior to placebo regarding treatment response. However, intolerability-related discontinuations were significantly higher compared to placebo with amisulpride and quetiapine. In adjunctive therapy (studies = 32, = 8349), ziprasidone [1.80 (1.07-3.04)], risperidone [1.59 (1.19-2.14)], aripiprazole [1.54 (1.35-1.76)], brexpiprazole [1.41 (1.21-1.66)], cariprazine [1.27 (1.07-1.52)], and quetiapine [1.23 (1.08-1.41)] were significantly superior to placebo regarding treatment response. However, of these antipsychotics that were superior to placebo, only risperidone was equivalent to placebo regarding discontinuation due to intolerability, while the other antipsychotics were inferior.
CONCLUSION
Results suggest that there are significant differences regarding the risk/benefit ratio among antipsychotics for MDD, which should inform clinical care.

Meta-Analysis Review
BACKGROUND
The evidence of treatment options' efficacy on acute bipolar manic episodes is relatively less in youths than adults. We aimed to compare and rank the drug's efficacy, acceptability, tolerability, and safety for acute mania in children and adolescents.
METHOD
We systematically reviewed the double-blinded, randomized controlled trials (RCTs) comparing drugs or placebo for acute manic episodes of bipolar disorder in children and adolescents using PRISMA guidelines. We searched PubMed/MEDLINE, EMBASE, Web of Science, EBSCO, Scopus, the Cochrane Central Register of Controlled Trials, and https://clinicaltrials.gov from inception until November 20, 2022. Response to treatment was the primary outcome, and random-effects network meta-analyses were conducted (PROSPERO 2022: CRD42022367455).
RESULTS
Of 10,134 citations, we included 15 RCTs, including 2372 patients (47 % female), 15 psychotropic drugs, and the placebo. Risperidone 0.5-2.5 mg/day, aripiprazole 30 mg/day olanzapine, quetiapine 400 mg/day, quetiapine 600 mg/day, asenapine 5 mg/day, asenapine 10 mg, ziprasidone, and aripiprazole 10 mg were found to be effective (in comparison with placebo) in children and adolescents, respectively (τ = 0.0072, I = 10.2 %). The tolerability of aripiprazole 30 mg/day was lower than risperidone 0.5-2.5 mg/day and olanzapine. Oxcarbazepine had the highest discontinuation due to the adverse effects risk ratio.
LIMITATIONS
Efficacy ranking of the treatments could be performed by evaluating relatively few RCT results, and only monotherapies were considered.
CONCLUSIONS
Efficacy, acceptability, tolerability, and safety are changing with the doses of antipsychotics for children and adolescents with acute bipolar manic episodes. Drug selection and optimum dosage should be carefully adjusted in children and adolescents.
