UNASSIGNED: The onset of psychotic symptoms occurs prior to age 19 in 39% of the patients with schizophrenia. There are limited approved treatment options for adolescents with schizophrenia. Brexpiprazole was approved by the United States Food and Drug Administration (FDA) for treatment of schizophrenia in adolescents in 2022.
UNASSIGNED: Extrapolation of adult data to youth and use of pharmacologic modeling coupled with open long-term safety data were used by the FDA to approve brexpiprazole for adolescent schizophrenia. They were all reviewed herein.
UNASSIGNED: D2 receptor partial agonist antipsychotic agents are preferred in the early phase of treatment of psychotic disorders. Approval of brexpiprazole in adolescent schizophrenia provides an additional option. Brexpiprazole was approved by the FDA on the basis of extrapolation of adult data without controlled trials in adolescents. This reduces placebo exposure in young people. Two previous agents (asenapine and ziprasidone) approved for adult schizophrenia failed to separate from placebo in adolescent schizophrenia studies; this partially undermines the process of extrapolation. For brexpiprazole, the paucity of data in adolescents relegates it to a second-line agent. More research on brexpiprazole is needed to delineate its relative role in the management of adolescent schizophrenia.

UNASSIGNED: This is a comprehensive review of the literature regarding the use of Lumateperone tosylate for schizophrenia. This review presents the background, evidence, and indications for the use of lumateperone tosylate in the treatment of schizophrenia.
UNASSIGNED: Schizophrenia is a chronic mental health disorder that affects approximately 3.3 million people in the United States. Its symptoms, which must be present more than six months, are comprised of disorganized behavior and speech, a diminished capacity to comprehend reality, hearing voices unheard by others, seeing things unseen by others, delusions, decreased social commitment, and decreased motivation. The majority of these symptoms can be managed with antipsychotic medication. Lumateperone is a selective and concurrent modulator of serotonin, dopamine, and glutamate, which all mediate or modulate serious mental illness.
UNASSIGNED: Schizophrenia is a complex, severe mental illness that affects how the brain processes information. There are many medications used to treat schizophrenia. One antipsychotic agent, lumateperone tosylate, is a newer agent that the FDA recently approved. The most common adverse effects are shown to be mild such as somnolence, constipation, sedation, and fatigue, with the 42 mg recommended dose. Lumateperone tosylate is an FDA-approved drug that can be given only at the 42mg dose once daily with no titration requirements.

OBJECTIVE: This is a comprehensive review of the literature regarding the use of Aripiprazole lauroxil for schizophrenia. This review presents the background, evidence, and indications for using aripiprazole lauroxil to treat schizophrenia in the context of current theories on the development of schizophrenia.
RESULTS: Schizophrenia is a chronic mental health disorder that currently affects approximately 3.3 million people in the United States. Its symptoms, which must be present for more than six months, are comprised of disorganized behavior and speech, a diminished capacity to comprehend reality, hearing voices unheard by others, seeing things unseen by others, delusions, decreased social commitment, and decreased motivation. The majority of these symptoms can be managed with antipsychotic medication. Aripiprazole lauroxil is a long-acting intramuscular injection that works as a combination of partial agonist activity at D2 and 5-HT1A receptors combined with antagonist activity at 5-HT2A receptors. It can be dosed as a 4-, 6-, or 8-week injection, depending on oral dosage. Aripiprazole lauroxil was FDA approved in October of 2015.
CONCLUSIONS: Schizophrenia is a severe psychiatric disorder if left untreated. There are multiple medications to help treat schizophrenia. One antipsychotic agent, aripiprazole lauroxil, offers long duration injections that optimize and improve compliance. Known side effects include weight gain, akathisia, neuroleptic malignant syndrome, tardive dyskinesia, and orthostatic hypotension. Aripiprazole lauroxil is an FDA-approved drug that can be administered monthly, every six weeks, or every two months and has been shown to be both safe and effective.

Schizophrenia is one of the top 25 causes of global diseases burdens in terms of years lived with the disease and the emotional and economical strains it imposes on the society. Several strategies have been used to treat the patients, specially using typical and atypical psychoactives. However, due to its multifactorial characteristic and patient resistance, schizophrenia is still a difficult disease to diagnose and treat. Thus, new strategies for diagnostics and treatment must be researched to optimize the efficacy and reduce the side effects of the actual therapy. Nanomedicine tries to improve low-weight molecular agents for treatment of diseases through the use of nanoscaled carriers. Among nanomedicine, nanopsychiatry specifically deals with the potential role of nanotechnology in solving psychiatry diseases problems. Therefore, the objective of this work is to provide an overview of the state of the art of nanopsychiatry in the sense of treating schizophrenia.

Olanzapine (OLZ), is used in the treatment of bipolar disorder and schizophrenia, diseases that present oxidative stress in their physiopathology. It has low aqueous solubility, which may lead to low oral bioavailability. The search of new drug delivery systems (DDSs) that may increase dissolution rate of OLZ, associated with the investigation of the antioxidant potential of the loaded-systems become of major importance to understand improvement in bipolar disorder and schizophrenia therapy. Thus, this study aimed to evaluate the in vitro antioxidant potential of two different Layered Double Hydroxides (LDH) loaded with 5% of OLZ (CaAl and NiAl), by radical scavenging activity (2,2-Diphenyl-1-picrylhydrazyl and nitric oxid); radical cation scavenging activity (2,2\'-azino-bis3-ethylbenzthiazoline-6-sulfonic acid ABTS) and evaluation of inhibition capacity of lipid peroxidation by thiobarbituric acid (TBARS). The results showed that both obtained LDH systems presented in vitro antioxidant capacity when associated with OLZ in all methods performed, and this activity is more pronounced with the systems containing OLZ compared to pure drug. The systems with CaAl was shown to have increased antioxidant potential, compared to NiAl, increasing the antioxidant activity up to 40,83%, 15,84% and 16,73%, as showed by the DPPH, nitric oxide and TBARS tests, respectively. The results revealed that the use of LDHs as a functional excipient may be promising in the pharmaceutical industry for bipolar disorder and schizophrenia therapy.

Nesfatin-1 and ghrelin are two hormones which has opposite effects and play role in food intake. This study was planned on the idea that both metabolic syndrome and psychiatric disorders are associated with nesfatin-1 and ghrelin. In this study, it was aimed to investigate the levels of ghrelin and nesfatin-1 in patients with schizophrenia, by taking confounding factor as the metabolic syndrome (MS). 55 patients with schizophrenia and 33 healthy controls were included in the study.11 out of the 55 patients (%20) has MS. Serum ghrelin and nesfatin-1 levels of schizophrenia patients with MS have been compared with both healthy controls and schizophrenia patients without MS. Patients with schizophrenia had significantly higher serum nesfatin-1 levels compared to healthy controls. But serum ghrelin levels was not different in both groups. Serum nesfatin-1 concentrations were significantly higher in the schizophrenia patients with MS (10.51-350.8pg/ml) with respect to the healthy control group (4.86-68.91pg/ml). There was no significant statistical difference between the three groups in terms of ghrelin levels. Our findings suggests that, MS presence also contributed to significantly high levels of nesfatin-1 level. Nesfatin-1 may have a part in a novel studies regarding the treatment of schizophrenia and its metabolic effects.

Treatment research studies employ criteria that determine which patients are eligible to participate and which are not. When such exclusion criteria produce a treatment research sample that is a small and unrepresentative subset of all patients with a particular disease, clinicians may be hesitant to apply the research results in front-line clinical practice. Accordingly, the present paper reviews the English-language literature on exclusion criteria in schizophrenia treatment research and draws initial conclusions about their impact. Empirically derived estimates of the rate of exclusion vary widely (31.0-98.2%), but the best available evidence suggests that about 4 in 5 patients with schizophrenia would be ineligible to enroll in a typical treatment research study. Women are particularly likely to be excluded from schizophrenia treatment research, which is problematic from both a clinical and social justice viewpoint. Excluded patients also tend to be older than eligible patients, and, though it has been examined in only a few studies, they also tend to have more severe problems at baseline and different outcomes over time than patients who are allowed to participate in research. More limited use of exclusion criteria in schizophrenia treatment research would be beneficial in terms of increasing generalizability, but would also potentially involve costs, particularly a need for larger samples. More modest steps that would improve treatment outcome research reports include requiring a full description of the rationale for, and nature of, any exclusion criteria, and, having a designated place in the discussion section which draws attention to the proper scope of generalization.

The dose of antipsychotic required for acute phase treatment of schizophrenia is well established, but there is no consensus on dose required for maintenance phase. Current guidelines do not provide definitive recommendations on the dose of antipsychotics needed in the maintenance treatment of schizophrenia, possibly due to limited research. In this retrospective study, minimum antipsychotic dose prescribed in maintenance treatment of schizophrenia in a real life situation was examined. Schizophrenia patients having Clinical Global Impression - Severity (CGI-S)≤3 for at-least six months during the maintenance phase treatment were included (n=163). The medical records of these patients were reviewed and the antipsychotic dose prescribed for acute and maintenance phase treatment was recorded. The mean antipsychotic dose used during maintenance treatment was approximately 30% lower than the dose used during acute phase. Importantly, about 40% of the subjects maintained well with a dose lesser than the recommended therapeutic range. Earlier age at onset and longer duration of illness were associated with higher antipsychotic dose requirement during the maintenance phase treatment. These findings could have important clinical implications if replicated in systematic prospective studies.
