Given the typical age onset of schizophrenia, there are tremendous economic and social impacts that extend beyond the person and their families. One critical determinant of the diseases' impact is the patient's adherence to antipsychotic drug treatment. Approved in 2015 for the treatment of schizophrenia, paliperidone palmitate (Invega Trinza, a 3-month injection, noted as PP3M) is a second-generation long-acting injectable antipsychotic medication. Among the different formulations offered for palmitate paliperidone, including the 1 and 3-month formulations, the longer duration 3-month formulation was better at preventing relapse in schizophrenic patients. To date, different formulations of palmitate paliperidone that have been studied on relapse episodes of schizophrenia include once-daily extended-release oral paliperidone (ORAL paliperidone), once-monthly paliperidone palmitate (PP1M), and once-every-3-months paliperidone palmitate (PP3M). analyses show that patients who were withdrawn from PP1M paliperidone had the least risk of relapse, followed by patients withdrawn from PP3M and patients withdrawn from ORAL paliperidone. PP3M was better at preventing relapse compared to ORAL paliperidone. The results demonstrated that 50% of patients who were withdrawn from ORAL paliperidone, PP1M, or PP3M remained relapse-free for ~2, 6, and 13 months, respectively. Compared to PP1M, PP3M is just as safe and effective and has the added advantage of increased adherence related to a longer dose interval, decreasing the risk of relapse.

Aim: This study aimed to explore the comparative risks for dystonia among different second-generation antipsychotics (SGAs), the influence of sex, and the relationship between the time-to-onset of dystonia and its outcomes.
Methods: We analyzed data from the Japanese Adverse Drug Event Report database from April 2004 to November 2023. Cases involving oral SGAs, excluding clozapine, were extracted.

Introduction: Daily oral antipsychotics (OAPs) are the mainstay of schizophrenia treatment; however, long-acting injectable antipsychotics (LAIs) are associated with better treatment adherence and improved outcomes.
Methods: This study assessed the real-world comparative effectiveness of LAIs and daily OAPs using claims data from a nationally representative sample of fee-for-service Medicare beneficiaries with schizophrenia. Antipsychotic discontinuation, psychiatric hospitalization, and treatment failure were compared relative to different reference groups using within-individual Cox regression models.

Bipolar disorder often begins in adolescence or early adulthood, characterized by recurrent manic episodes that can lead to neurodegenerative brain changes and functional decline. While several oral second-generation antipsychotics are Food and Drug Administration (FDA)-approved for mania, adherence to maintenance treatment is frequently poor due to factors such as anosognosia, cognitive dysfunction, impulsivity, side effects aversion, and substance use. Long-acting injectable (LAI) antipsychotics, approved for adults with bipolar mania or schizoaffective disorder (bipolar type), offer a potential solution for adolescents with similar conditions.

Introduction: The benefits of long-acting injectable antipsychotics have been documented in several observational studies, but data remain scarce in Latin America. This study aimed at evaluating the effectiveness of paliperidone palmitate once monthly (PP1M) on treatment adherence and relapse in the schizophrenia population followed in a government-funded mental health care facility in Colombia.
Methods: A mirror-image study was conducted.

Schizophrenia is a complex and chronic psychiatric disorder that significantly impacts patients' quality of life. Ranking 12th among 310 diseases and injuries that result in disability, the number of patients suffering from schizophrenia continues to rise, emphasizing the urgent need for developing effective treatments. Despite the availability of effective antipsychotic drugs, over 80% of patients taking oral antipsychotics experience relapses, primarily caused by non-adherence as the high dosing frequency is required.
