Efficacy and safety of long-acting injectable versus oral antipsychotics in the treatment of patients with early-phase schizophrenia-spectrum disorders: a systematic review and meta-analysis. Ther Adv Psychopharmacol 2024; 14:20451253241257062. [PMID: 38831918 PMCID: PMC11145998 DOI: 10.1177/20451253241257062] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/05/2023] [Accepted: 05/03/2024] [Indexed: 06/05/2024] Open
Abstract
Background Long-acting injectable antipsychotics (LAIs) have advantages over oral antipsychotics (OAPs) in preventing relapse and hospitalization in chronically ill patients with schizophrenia-spectrum disorders (SSDs), but evidence in patients with first-episode/recent-onset, that is, early-phase-SSDs is less clear. Objectives To assess the relative medium- and long-term efficacy and safety of LAIs versus OAPs in the maintenance treatment of patients with early-phase SSDs. Method We searched major electronic databases for head-to-head randomized controlled trials (RCTs) comparing LAIs and OAPs for the maintenance treatment of patients with early-phase-SSDs. Design Pairwise, random-effects meta-analysis. Relapse/hospitalization and acceptability (all-cause discontinuation) measured at study-endpoint were co-primary outcomes, calculating risk ratios (RRs) with their 95% confidence intervals (CIs). Subgroup analyses sought to identify factors moderating differences in efficacy or acceptability between LAIs and OAPs. Results Across 11 head-to-head RCTs (n = 2374, median age = 25.2 years, males = 68.4%, median illness duration = 45.8 weeks) lasting 13-104 (median = 78) weeks, no significant differences emerged between LAIs and OAPs for relapse/hospitalization prevention (RR = 0.79, 95%CI = 0.58-1.06, p = 0.13) and acceptability (RR = 0.92, 95%CI = 0.80-1.05, p = 0.20). The included trials were highly heterogeneous regarding methodology and patient populations. LAIs outperformed OAPs in preventing relapse/hospitalization in studies with stable patients (RR = 0.65, 95%CI = 0.45-0.92), pragmatic design (RR = 0.67, 95%CI = 0.54-0.82), and strict intent-to-treat approach (RR = 0.64, 95%CI = 0.52-0.80). Furthermore, LAIs were associated with better acceptability in studies with schizophrenia patients only (RR = 0.87, 95%CI = 0.79-0.95), longer illness duration (RR = 0.88, 95%CI = 0.80-0.97), unstable patients (RR = 0.89, 95%CI = 0.81-0.99) and allowed OAP supplementation of LAIs (RR = 0.90, 95%CI = 0.81-0.99). Conclusion LAIs and OAPs did not differ significantly regarding relapse prevention/hospitalization and acceptability. However, in nine subgroup analyses, LAIs were superior to OAPs in patients with EP-SSDs with indicators of higher quality and/or pragmatic design regarding relapse/hospitalization prevention (four subgroup analyses) and/or reduced all-cause discontinuation (five subgroup analyses), without any instance of OAP superiority versus LAIs. More high-quality pragmatic trials comparing LAIs with OAPs in EP-SSDs are needed. Trial registration CRD42023407120 (PROSPERO).

Model-Informed Clinical Development of 6-Monthly Injection of Paliperidone Palmitate in Patients with Schizophrenia: Dosing Strategies Guided by Population Pharmacokinetic Modeling and Simulation (Part II). Eur J Drug Metab Pharmacokinet 2024:10.1007/s13318-024-00899-z. [PMID: 38769284 DOI: 10.1007/s13318-024-00899-z] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Accepted: 04/28/2024] [Indexed: 05/22/2024]
Abstract
BACKGROUND AND OBJECTIVE Paliperidone palmitate 6-month (PP6M) intramuscular (IM) injection is the longest-acting treatment available for patients with schizophrenia. A population pharmacokinetic (popPK) modeling and simulation approach was deployed to inform dosing strategies for PP6M. METHODS The extensive analysis database included 15,932 paliperidone samples from 700 patients receiving gluteal paliperidone palmitate 3-month (PP3M) or PP6M injections in the double-blind phase of a phase-3 noninferiority study (NCT03345342). Exposure parameters for paliperidone appeared to increase dose-proportionally within each dosing schedule (PP3M/PP6M). The range of paliperidone exposures after IM administration of PP6M overlaps with that of corresponding doses of oral paliperidone extended release, PP 1-month (PP1M), and PP3M. Model-based simulations were performed to investigate paliperidone exposures in different PP6M dosing scenarios and relevant subpopulations. RESULTS A dosing window of ≤ 2 weeks earlier and ≤ 3 weeks later than the target 6-month interval for maintenance treatment with PP6M dosing maintains paliperidone exposures at levels that are not expected to substantially impact its safety and efficacy. For missed-dose scenarios, tailored re-initiation regimens are proposed that should be applied before resuming PP6M maintenance dosing. Regarding subpopulations, PP6M 700 mg eq. is the highest dose recommended in mild renal-impairment patients; the paliperidone pharmacokinetics after PP6M administration is not affected by sex, body mass index, or age in a clinically meaningful way. CONCLUSION Paliperidone concentration-time profiles after PP6M and PP3M dosing were adequately described by the popPK model. Model-based simulation results provide guidance for clinicians on initiating PP6M therapy, transitioning between paliperidone formulations, the dosing windows to use for maintenance dosing, and managing missed PP6M doses.

Relapse Rates With Paliperidone Palmitate in Adult Patients With Schizophrenia: Results for the 6-Month Formulation From an Open-label Extension Study Compared to Real-World Data for the 1-Month and 3-Month Formulations. Int J Neuropsychopharmacol 2024; 27:pyad067. [PMID: 38300235 PMCID: PMC10873782 DOI: 10.1093/ijnp/pyad067] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/28/2023] [Accepted: 01/29/2024] [Indexed: 02/02/2024] Open
Abstract
BACKGROUND The 3 paliperidone palmitate (PP) long-acting injectable antipsychotic formulations, PP 1-month (PP1M), PP 3-month (PP3M), and PP 6-month (PP6M), have shown to reduce the risk of relapse in schizophrenia. The current phase-4 study constructed external comparator arms (ECAs) using real-world data for PP3M and PP1M and compared relapse prevention rates with PP6M from an open-label extension (OLE) study in adult patients with schizophrenia. METHODS PP6M data were derived from a single-arm, 24-month, OLE study (NCT04072575), which included patients with schizophrenia who completed a 12-month randomized, double-blind, noninferiority, phase-3 study (NCT03345342) without relapse. Patients in the PP3M and PP1M ECAs were identified from the IBM® MarketScan® Multistate Medicaid Database based on similar eligibility criteria as the PP6M cohort. RESULTS A total of 178 patients were included in each cohort following propensity score matching. Most patients were men (>70%; mean age: 39-41 years). Time to relapse (primary analysis based on Kaplan-Meier estimates) was significantly delayed in the PP6M cohort (P < .001, log-rank test). The relapse rate was lower in the PP6M cohort (3.9%) vs PP3M (20.2%) and PP1M (29.8%) cohorts. Risk of relapse decreased significantly (P < .001) by 82% for PP6M vs PP3M (HR = 0.18 [95% CI = 0.08 to 0.40]), 89% for PP6M vs PP1M (HR = 0.11 [0.05 to 0.25]), and 35% for PP3M vs PP1M (HR = 0.65 [0.42 to 0.99]; P = .043). Sensitivity analysis confirmed findings from the primary analysis. Although the ECAs were matched to mimic the characteristics of the PP6M cohort, heterogeneity between the groups could exist due to factors including prior study participation, unmeasured confounders, variations in data capture and quality, and completeness of clinical information. CONCLUSIONS In a clinical trial setting, PP6M significantly delayed time to relapse and demonstrated lower relapse rates compared with PP3M and PP1M treatments in real-world settings among adult patients with schizophrenia.

Baune BT. Aripiprazole 2-month ready-to-use 960 mg (Ari 2MRTU): review of its possible role in schizophrenia therapy. Curr Med Res Opin 2024; 40:87-96. [PMID: 37999650 DOI: 10.1080/03007995.2023.2287612] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/09/2023] [Accepted: 11/21/2023] [Indexed: 11/25/2023]
Abstract
Most patients with schizophrenia need life-long treatment. There is therefore a continued need for effective and tolerable treatment options. A 2-monthly LAI formulation of aripiprazole, Aripiprazole 2-Month Ready-to-Use 960 mg (Ari 2MRTU 960) has recently been approved in the US. Here, the possible role in therapy for this new treatment option is discussed in a narrative review. PubMed was searched for literature on long-acting injectables with a focus on patient-reported outcomes and real-world evidence on extended injection intervals (2-3 months). Dopamine D2 partial agonists, one of which is aripiprazole, exhibit favorable tolerability and safety properties. Additionally, there are many advantages in using long-acting injectable formulations such as enhanced treatment persistence and stability of patients as well as reduced rates of relapses, hospitalizations, and death. Some of these advantages become more pronounced with longer injection intervals. Additional advantages of longer injection intervals are more room for non-medication-related communication between healthcare professionals and patients, patient and physician preferences, reduced caregiver burden, and easier transitioning from inpatient to outpatient treatment. Taken together, since aripiprazole may be a good treatment choice for many patients based on its favorable safety and tolerability profile, and given the advantages of LAI treatment over oral treatment and the advantages of reduced dosing frequency, Ari 2MRTU 960 may become an important treatment option for many clinically stable patients with schizophrenia.

Abstract
Since the end of 2019, the global spread of COVID-19 has represented a historic event that changed our way of treating patients globally. The use of long-acting injections (LAI) antipsychotics was emphasized. Our goal was to investigate the impact of COVID-19 on the frequency of prescribing LAI and compare it with a period before. All patients (198) who started LAI-risperidone or LAI-paliperidone for the period 2017-2022, in Kragujevac, the city in Central Serbia, were considered. The frequency of prescribing LAI before and during COVID-19 and the total number of prescribed LAI per year were compared. Separately, the frequency of prescribing LAI-R and the frequency of prescribing LAI-P were compared. The significant (p < 0,05) increase in the use of LAI risperidone and paliperidone was in 2020 and 2021 [per year 2017(3), 2018(6), 2019(26), 2020(75), 2021(55), and 2022(33)]. The significant (p < 0,05) increase in monthly and quarterly preparations of LAI paliperidone was in 2020 and 2021 relative to the years before the pandemic. As the pandemic weakened, the inclusion of LAI paliperidone therapy weakened during 2022. A significant increase in usage of LAI risperidone was in 2022, and in 2020 and 2021 was as it was in the period 2017-2019. During COVID-19, especially in years when COVID-19 restriction measures were stricter, there was a significant change in the application method of antipsychotic therapy in favor of LAI. Regardless of the increase in treatment costs, patients' interests and protection were prioritized in the treatment process.

Abstract
BACKGROUND Severe mental illness (SMI) incorporates schizophrenia, bipolar disorder, non-organic psychosis, personality disorder or any other severe and enduring mental health illness. Medication, particularly antipsychotics and mood stabilisers are the main treatment options. Medication optimisation is a hallmark of medication safety, characterised by the use of collaborative, person-centred approaches. There is very little published research describing medication optimisation with people living with SMI. OBJECTIVE Published literature and two stakeholder groups were employed to answer: What works for whom and in what circumstances to optimise medication use with people living with SMI in the community? METHODS A five-stage realist review was co-conducted with a lived experience group of individuals living with SMI and a practitioner group caring for individuals with SMI. An initial programme theory was developed. A formal literature search was conducted across eight bibliographic databases, and literature were screened for relevance to programme theory refinement. In total 60 papers contributed to the review. 42 papers were from the original database search with 18 papers identified from additional database searches and citation searches conducted based on stakeholder recommendations. RESULTS Our programme theory represents a continuum from a service user's initial diagnosis of SMI to therapeutic alliance development with practitioners, followed by mutual exchange of information, shared decision-making and medication optimisation. Accompanying the programme theory are 11 context-mechanism-outcome configurations that propose evidence-informed contextual factors and mechanisms that either facilitate or impede medication optimisation. Two mid-range theories highlighted in this review are supported decision-making and trust formation. CONCLUSIONS Supported decision-making and trust are foundational to overcoming stigma and establishing 'safety' and comfort between service users and practitioners. Avenues for future research include the influence of stigma and equity across cultural and ethnic groups with individuals with SMI; and use of trained supports, such as peer support workers.

Abstract
BACKGROUND Evaluate efficacy and safety of paliperidone palmitate 6-monthly (PP6M) for patients with schizophrenia in the Asian subgroup of a global, multicenter, noninferiority phase-3 study (NCT03345342). METHODS Patients received paliperidone palmitate 1-monthly (PP1M, 100/150 mg eq.) or paliperidone palmitate 3-monthly (PP3M, 350/525 mg eq.) during the maintenance phase and entered a 12-month double-blind (DB) phase, wherein they were randomized (2:1) to PP6M (700/1000 mg. eq.) or PP3M (350/525 mg eq.). Subgroup analysis was performed for 90 (12.7%) patients from Asia region (India, Taiwan, Malaysia, Hong Kong, and Korea). Primary endpoint was time-to-relapse during DB phase (Kaplan-Meier estimates). Secondary endpoints were changes from baseline in Positive and Negative Syndrome Scale, Clinical Global Impression-Severity scale, Personal and Social Performance (PSP) scale score. RESULTS In Asian subgroup, 91.9% (82/90) of patients completed DB phase (PP6M: 54/62 [87%]; PP3M: 28/28 [100%]). Median time-to-relapse was "not-estimable" due to low relapse rates in both groups. Estimated difference (95% confidence interval [CI]) between relapse-free patients in PP6M and PP3M groups of Asian subgroup was -0.1% [-8.5%, 8.4%] (global study population: -2.9% [-6.8%, 1.1%]). Mean change from baseline in secondary efficacy parameters was comparable between both groups, similar to the global study population. The incidence of extrapyramidal symptoms was higher in the Asian subgroup than in the global study population. CONCLUSION Consistent with the global study population, PP6M was noninferior to PP3M in preventing relapse in patients with schizophrenia from the Asia region. Findings suggest the possibility of switching from PP1M/PP3M to twice-yearly PP6M without loss of efficacy and with no unexpected safety concerns.

Abstract
Introduction Poor adherence to antipsychotic medication is common in the treatment of schizophrenia and other psychotic disorders. Paliperidone palmitate 3-monthly (PP3M) is the first long-acting injectable (LAI) antipsychotic to allow for only four medication administrations per year, and although there is sufficient information available about the clinical effects, there is relatively limited insight into the subjective experience of people with lived experience. Methods This descriptive, cross-sectional survey explored patient's satisfaction and perspectives on the advantages and disadvantages of switching from monthly to 3-monthly paliperidone while also reporting on perceived levels of safety with regard to the reducing dose regimen during the Covid-19 pandemic. Information on discontinuation and hospitalisation rates at one year was also collected from the electronic records. Results Of the 46 patients included in the study, the vast majority reported feeling satisfied (89.2%) and safer (93.5%) after switching to the three-monthly formulation. Participants highlighted several advantages of changing to PP3M, most notably convenience (93.5%), improved quality of life (58.7%), decreased stigma (39.1%) and better adherence (28.3%). Furthermore, 93.5% of respondents experienced no disadvantages, while 6.5% described worsening side effects or symptoms. In fact, only one patient discontinued PP3M at one year with the overall number of hospitalisations also reducing in the same period compared to the year before switching. Discussion Our findings add to the small, but growing, body of evidence supporting patient satisfaction and acceptance with the use of PP3M and may reinforce the use of less frequent LAIs in clinical practice to enhance individual experience and treatment persistence and decrease levels of stigmatisation.

Effectiveness of SGA-LAIs on Clinical, Cognitive, and Social Domains in Schizophrenia: Results from a Prospective Naturalistic Study. Brain Sci 2023; 13:brainsci13040577. [PMID: 37190542 DOI: 10.3390/brainsci13040577] [Citation(s) in RCA: 3] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/28/2023] [Revised: 03/21/2023] [Accepted: 03/26/2023] [Indexed: 03/31/2023] Open
Abstract
We hypothesized that shifting from oral second-generation antipsychotics (SGA) to their long-acting injectable (LAI) counterpart would be beneficial for the psychopathological, cognitive, social, and general health domains in outpatients suffering from schizophrenia. We aimed to evaluate the prospective usefulness of SGA-LAI treatment by carrying out a head-to-head comparison of two different medications (i.e., aripiprazole monohydrate (Ari-LAI) and paliperidone palmitate 1 and 3 month (PP1M, PP3M)) in a real-world setting, assessing the effectiveness and tolerability of Ari-LAI and PP1M/PP3M over a 15 month follow-up. A total of 69 consecutive individuals affected by schizophrenia were screened for eligibility. Finally, 46 outpatients (29 treated with Ari-LAI, 13 with PP1M, and four with PP3M) were evaluated through clinical, functional, and neuropsychological assessment administrated at baseline and after 3-, 12-, and 15-month follow-up periods. Moreover, periodic general medical evaluations were carried out. We estimated an overall improvement over time on the explored outcomes, without differences with respect to the type of LAI investigated, and with a global 16.4% dropout rate. Our findings suggest that switching from oral SGA to SGA-LAIs represents a valid and effective treatment strategy, with significant improvements on psychopathological, cognitive, social, and clinical variables for patients suffering from schizophrenia, regardless of the type of molecule chosen.

Achieving long-term goals through early personalized management of schizophrenia: expert opinion on the role of a new fast-onset long-acting injectable antipsychotic. Ann Gen Psychiatry 2023; 22:1. [PMID: 36650545 PMCID: PMC9843844 DOI: 10.1186/s12991-022-00430-1] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/29/2022] [Accepted: 12/29/2022] [Indexed: 01/18/2023] Open
Abstract
Definition of an appropriate and personalized treatment plan focused on long-term outcomes is crucial in the management of schizophrenia. Following review of the literature, a panel of six leading psychiatrists discussed the importance of clear and shared long-term goals when initiating antipsychotic treatment in light of their clinical experience. The importance of establishing shared and progressive treatment objectives was stressed, which should be tailored based on the patient's characteristics, goals, and preferences. Consensus emerged on the key role that therapeutic alliance and patient empowerment play throughout the course of treatment. Reduction in symptoms in the acute phase along with good efficacy and tolerability in the maintenance phase emerged as essential features of a therapy that can favor achievement of long-term outcomes. Long-acting injectable (LAI) antipsychotics enhance adherence to treatment compared to oral formulations and have been shown to be effective in the maintenance phase. Currently available LAIs are characterized by a delayed onset of action and require a loading dose or oral supplementation to achieve therapeutic concentrations. Risperidone ISM® is a novel LAI antipsychotic with fast and sustained release of antipsychotic, reaching therapeutic plasma levels within a few hours after administration without oral supplementation or loading doses. Risperidone ISM® has been shown to rapidly control symptoms in patients with an acute exacerbation of schizophrenia and to be effective and well tolerated as maintenance treatment irrespective of the severity of initial symptoms. It thus represents a valuable and novel therapeutic option in management of schizophrenia.

The Effect of Longer Dosing Intervals for Long-Acting Injectable Antipsychotics on Outcomes in Schizophrenia. Neuropsychiatr Dis Treat 2023; 19:531-545.

Abstract
Medication nonadherence in schizophrenia can have serious implications including relapses and hospitalization. Long-acting injectable (LAI) antipsychotics require fewer administrations, while ensuring sustained medication coverage. In this review, we summarize the expected real-world benefits of longer dosing intervals in the management of schizophrenia. LAIs are associated with improved clinical outcomes of less frequent relapses and reduced functional impairment, encouraging patients to regain control of their lives. Aripiprazole lauroxil and paliperidone palmitate three-monthly (PP3M) LAIs have longer dosing intervals of 2-3 months and provide improved outcomes in patients with schizophrenia. Paliperidone palmitate six-monthly (PP6M) LAI provides the longest dosing interval, twice-yearly dosing, among existing LAIs. Decreasing the frequency of LAI administrations has the potential to reduce occurrence of serious outcomes associated with poor medication adherence. By eliminating the need for daily oral antipsychotic dosing, LAIs could increase the likelihood of patient acceptance, decrease stigma, and promote self-esteem. Longer intervals of medication coverage may be desirable for patients with higher risk of relapse including adults with recent-onset schizophrenia, those living in circumstances that may deprive them of regular access (eg, homeless), those that are in transitions between care settings or to reduce interpersonal contact during public health emergencies (eg, COVID-19 pandemic).

Abstract
Schizophrenia is a severe mental illness causing a high degree of disability. First- and second-generation antipsychotics (FGAs and SGAs) represent key resources for its acute and long-term management. Since a poor adherence to oral treatments may negatively impact the course of the disorder, long-acting injectable antipsychotics (LAIs) are often used to reduce clinical relapses. Notwithstanding their potential beneficial features, LAIs use in clinical practice remains somewhat hampered by the limited amount of relevant systematic information. This review thus aims at providing a clinical, practical guidance for the use of LAIs in the treatment of schizophrenia. We synthetized main information on indications, dosage, and administration of LAIs approved by the US Food and Drug Administration (FDA) and/or in EU countries, as well as evidence from the most recent systematic reviews and meta-analyses. Currently available information, though heterogeneous, shows that LAIs can prevent relapses and rehospitalizations, improving clinical outcomes and favouring sustained remission among people with schizophrenia. The use of SGA LAIs is supported by more robust evidence than FGA LAIs. Along with their positive impact on the prevention of treatment discontinuation, some LAIs might also enhance individual global functioning and quality of life, without additional adverse events or health-care costs, as compared with oral antipsychotics. Although which LAIs can be considered a first-choice option, as well as their superiority over oral antipsychotics, remain unclear issues, this review offers a comprehensive overview of information available on the use of LAIs for people with schizophrenia, providing clinicians with practical guidance in terms of efficacy and acceptability of single agents. Literature gaps and future research needs are also described.

Abstract
Background Olanzapine pamoate has been shown to be an effective second-generation long-acting injection. Its popularity has possibly been adversely affected by the rare incidence of post-injection syndrome (PIS) and the associated requirement to monitor for 3 h after each injection. Objective This study aimed to collect and present data on the use of olanzapine long-acting injection (OLAI) over a 10-year period in a high-security forensic hospital in South East England. Design This was a non-interventional retrospective study collecting information from anonymised electronic patient and prescription records. As per hospital Trust guidelines, patient consent to access of hospital records was presumed unless explicitly withdrawn. Method All patients prescribed OLAI between the years 2009 and 2019 were identified. Data collected included date that OLAI was started, stopped, dose range, side effects and concomitant medication. Results Of 88 patients who were started OLAI, 45 (51%) continued at month 24. At 60 months, 22 of 70 (31%) patients for whom data were available continued with OLAI. Over 60% of continuers were on higher than recommended doses. Of almost 5000 injections administered, there was 1 episode of PIS. Conclusion OLAI is an effective treatment for schizophrenia and schizoaffective disorder, especially when used in patients have been able to tolerate the drug and were stabilised on it for 24 months. In over half the patients who continued OLAI, the doses were higher than that recommended by the manufacturer. The incidence of PIS in this study was very low in comparison with other studies. Registration code 2049.

Abstract
AIM Long-acting injectable antipsychotic drugs (LAIs) are often used as an alternative to oral antipsychotics (OAPs) in individuals with psychosis who demonstrate poor medication adherence. Previous meta-analyses have found mixed results on the efficacy of LAIs, compared to OAPs, in patients with psychotic disorders. The objective of this meta-analysis was to compare the effectiveness of using LAIs versus OAPs in the early stages of psychosis. METHODS Major electronic databases were used to search for any studies examining the comparative effectiveness (i.e., relapse, adherence, hospitalization, and all-cause discontinuation) of any LAIs versus OAPs in early stages of psychosis. Studies published up to 6 June, 2019 were included and no language restriction was applied. Inclusion criteria were a diagnosis of schizophrenia or related disorder, where patients were in their first episode or had a duration of illness ≤5 years. Data were analysed using a random-effects model. RESULTS Fifteen studies (n = 10 584) were included, of which were 7 RCTs, 7 observational studies, and 1 post-hoc analysis. We found that LAIs provided advantages over OAPs in terms of relapse rates. No significant differences were found between LAI and OAP groups in terms of all-cause discontinuation, hospitalization, and adherence rates. However, considering only RCTs revealed advantages of LAIs over OAPs in terms of hospitalization rates. CONCLUSIONS LAIs may provide benefits over OAPs with respect to reducing relapse and hospitalization rates in early psychosis patients. There is a need for larger and better-designed studies comparing OAPs and LAIs specifically in early psychosis patients.

Abstract
PURPOSE Paliperidone palmitate is the only available long acting injectable (LAI) antipsychotic with a monthly and three-monthly formulation. LAIs may help battle non-adherence. Studies about the experiences of switching from the monthly (PP1M) to the three-monthly formulation (PP3M) of paliperidone are scarce. Therefore, the aim of this study is to evaluate the perspectives of patients, relatives, and mental health professionals on PP3M compared with PP1M. MATERIAL AND METHODS This was a multicenter, retrospective, non-interventional one-time questionnaire survey among patients with psychotic disorders who switched from PP1M to PP3M (n = 38), their relatives (n = 13) and mental health professionals (n = 38). General satisfaction and (un)desired effects were measured using the Medication Satisfaction Questionnaire (MSQ) and the Subjects' Reaction to Antipsychotics (SRA), respectively. Additional questionnaires assessed socio-demographic variables, preference, effectiveness, side-effects, and confidence in PP3M compared to PP1M. RESULTS Mean number of received PP3M injections was 4.2 (SD 2.5). The three study groups reported a high level of confidence in PP3M. High general satisfaction rates about PP3M among patients (69%) and mental health professionals (95%) were reported. The majority of patients, relatives, and mental health professionals reported similar or in some cases even greater effectiveness and similar or in some cases even less side-effects of PP3M compared to PP1M. Sixty-seven percent of the relatives reported less concerns about non-adherence after switching to PP3M. CONCLUSION Most patients, relatives, and mental health professionals prefer PP3M over PP1M. The positive attitudes of all parties may facilitate the more frequent use of PP3M and potentially the clinical outcomes.

Abstract
PURPOSE To describe changes due to the COVID-19 pandemic in the prescribing of long-acting antipsychotics (LAI) for schizophrenia, patient outcomes, and patient and healthcare provider (HCP) attitudes regarding COVID-19 vaccination in the United States (US). METHODS An anonymous online survey was administered to US-based LAI prescribers with a psychiatry specialty in May 2021. Information on prescriber and clinical practice characteristics, LAI prescribing, patient outcomes, and attitudes toward COVID-19 vaccination was collected and described. RESULTS Of the 401 LAI prescribers meeting survey criteria, 64.6% reported that LAI prescribing remained unchanged (increase: 19.2%, decrease: 14.0%). The majority did not switch patients from LAIs to oral antipsychotics (OAP; 63.3%) or to LAI formulations with lower frequency of administration (68.1%); most prescribers switched the same number of patients from OAPs to LAIs during the pandemic as in previous practice (65.1%). Half of LAI prescribers (50.1%) reported antipsychotic adherence as unchanged among most patients; 44.6% reported symptom control/relapse frequency as unchanged. Most prescribers believed their patients with schizophrenia should be prioritized for COVID-19 vaccination (74.1%) and encouraged all patients to obtain a COVID-19 vaccine (84.0%). However, 64.1% of prescribers reported hesitancy among some patients about vaccines' safety; 51.4% reported that some patients were willing to be vaccinated despite the hesitancy, 48.6% indicated that some patients perceived COVID-19 vaccines as safe, effective, and important. CONCLUSION LAI prescribing and prescriber-reported antipsychotic adherence in patients with schizophrenia remained largely unchanged approximately one year after the start of COVID-19. Focused efforts to overcome patients' COVID-19 vaccine hesitancy are warranted.

Abstract
PURPOSE Antipsychotic long-acting injections (AP-LAIs) are indicated for patients affected by schizophrenia especially those with poor treatment adherence. PATIENTS AND METHODS To compare paliperidone palmitate 3-monthly (PP3M), paliperidone palmitate one-monthly (PP1M) and haloperidol decanoate (HAL-D) treatment, we enrolled 90 patients with schizophrenia treated in Mental Health Center with one of the three AP-LAIs for at least six months and followed them for another 6 months. At 6 and 12 months of treatment we administered Clinical Global Impression-Severity, Global Assessment of Functioning and World Health Organization Quality of Life-26 items (WHOQOL-BREF). At 1-year treatment, we evaluated relapses (psychiatric hospitalizations and urgent consultations), side effects and drop-outs. RESULTS We did not highlight any statistically significant difference among the three treatments in relapses and scale scores. Weight increase was significantly higher in PP1M and PP3M groups. Twelve patients (13.3%) discontinued AP-LAI. At 1-year AP-LAI treatment, 69% of patients rated quality of life as "good" or "very good" and 71% declared themselves to be "satisfied" or "very satisfied". CONCLUSION HAL-D, PP1M and PP3M 1-year treatments were similarly effective in preventing relapses and improving quality of life and health satisfaction. All discontinuations in the new 3-monthly antipsychotic treatment were caused by patient refusal to continue it.

[PMID: 34791283 PMCID: PMC8929757 DOI: 10.1093/ijnp/pyab071] [Citation(s) in RCA: 24] [Impact Index Per Article: 8.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/01/2021] [Revised: 10/18/2021] [Accepted: 11/10/2021] [Indexed: 12/11/2022] Open
Abstract
BACKGROUND This double-blind (DB), randomized, parallel-group study was designed to evaluate efficacy and safety of paliperidone palmitate 6-month (PP6M) formulation relative to paliperidone palmitate 3-month (PP3M) formulation in patients with schizophrenia. METHODS Following screening, patients entered an open-label (OL) maintenance phase and received 1 injection cycle of paliperidone palmitate 1-month (PP1M; 100 or 150 mg eq.) or PP3M (350 or 525 mg eq.). Clinically stable patients were randomized (2:1) to receive PP6M (700 or 1000 mg eq., gluteal injections) or PP3M (350 or 525 mg eq.) in a 12-month DB phase; 2 doses of PP6M (corresponding to doses of PP1M and PP3M) were chosen. RESULTS Overall, 1036 patients were screened, 838 entered the OL phase, and 702 (mean age: 40.8 years) were randomized (PP6M: 478; PP3M: 224); 618 (88.0%) patients completed the DB phase (PP6M: 416 [87.0%]; PP3M: 202 [90.2%]). Relapse rates were PP6M, 7.5% (n = 36) and PP3M, 4.9% (n = 11). The Kaplan-Meier estimate of the difference (95% CI) between treatment groups (PP6M - PP3M) in the percentages of patients who remained relapse free was -2.9% (-6.8%, 1.1%), thus meeting noninferiority criteria (95% CI lower bound is larger than the pre-specified noninferiority margin of -10%). Secondary efficacy endpoints corroborated the primary analysis. Incidences of treatment-emergent adverse events were similar between PP6M (62.1%) and PP3M (58.5%). No new safety concerns emerged. CONCLUSIONS The efficacy of a twice-yearly dosing regimen of PP6M was noninferior to that of PP3M in preventing relapse in patients with schizophrenia adequately treated with PP1M or PP3M.

Abstract
OBJECTIVE Switching to long-acting injectable (LAI) antipsychotic maintenance treatment (AMT) represents a valuable strategy for schizophrenia. In a recovery-oriented approach, patient-reported outcomes (PROs) such as perceived disability, subjective well-being, and quality of life cannot be neglected. METHODS Forty clinically stable outpatients with schizophrenia treated with oral second-generation antipsychotics were enrolled at the time of switching to the equivalent dose of LAI. 35 subjects completed this 2-year longitudinal, prospective, open-label, observational study. Patients were assessed at baseline, after 1 year, and after 2 years of LAI-AMT, using psychometric scales (Positive And Negative Syndrome Scale, PANSS; Young Mania Rating Scale, YMRS; Montgomery-Åsberg Depression Rating Scale, MADRS), PROs (Subjective Well-Being under Neuroleptics short form, SWN-K; Short Form-36 health survey, SF-36; 12-item World Health Organisation Disability Assessment Schedule, WHODAS 2.0), and caregiver-reported outcomes (12-item WHODAS 2.0). RESULTS No psychotic relapses were observed. Psychopathology measures (PANSS total and subscales - excluding negative symptoms), mood symptoms (YMRS, MADRS), perceived disability (patient- and caregiver-administered WHODAS 2.0), subjective well-being (SWN-K), and quality of life (SF-36) showed a concomitant amelioration after 1 year, without further significant variations. DISCUSSION Switching to LAI-AMT may decrease perceived impairment, and increase subjective well-being and quality of life in clinically stable outpatients with schizophrenia.HighlightsLAI treatment may improve outcomes by reducing psychopathology levels and relapses.In a recovery-oriented approach, patient-reported outcomes cannot be neglected.LAI antipsychotics may optimise the subjective experience of treatment.Switching to LAI therapy may result in a reduction in perceived disability.There is a significant correlation between proxy- and patient-reported disability.

BMC Psychiatry 2021; 21:300.

Abstract
BACKGROUND To understand the implications of switching from paliperidone palmitate 1-monthly (PP1M) to paliperidone palmitate 3-monthly (PP3M) treatment of schizophrenia from the perspective of four key stakeholders: patients, physicians, nurses and carers. METHODS This was a cross-sectional, retrospective, non-interventional study comprising a one-time questionnaire (PINC-Q) for adult patients (aged ≥18 years) with schizophrenia (International Classification of Diseases; ICD-10) and their physician, nurse and carer. Questionnaires were developed in association with patient and carer advocacy groups (GAMIAN and EUFAMI) and following an advisory board formed of psychiatrists and nurses. The degree of alignment between stakeholders was also examined. RESULTS Responses were received from a total of 224 evaluable patients. For most patients (88.4%), responses were received from at least two other stakeholders. Patients were moderately ill with mild-to-moderate lack of insight and had received PP1M for a mean (standard deviation [SD]) of 23.9 (21.28) months before switching to PP3M (duration mean [SD] 12.8 [3.72] months). The most frequently reported reasons to switch from PP1M to PP3M were 'to live life as normally as possible' and 'patient convenience'. Over 79% of responses within each stakeholder group stated that PP3M helped the patients, with increased patient activity and social involvement, improved frequency and quality of physician-patient and nurse-patient communication and decreased perceived stigma. CONCLUSIONS The results of this study add to the increasing body of evidence supporting the benefits of PP3M in a population of patients with schizophrenia representative of real-world clinical practice.

Abstract
OBJECTIVE This study compared relapse prevention and acceptability of long-acting injectable (LAI) antipsychotics in the maintenance treatment of adults with nonaffective psychoses. METHODS The authors searched MEDLINE, Embase, PsycINFO, CINAHL, CENTRAL, and online registers for randomized controlled trials published until June 2020. Relative risks and standardized mean differences were pooled using random-effects pairwise and network meta-analysis. The primary outcomes were relapse rate and all-cause discontinuation ("acceptability"). The quality of included studies was rated with the Cochrane Risk of Bias tool, and the certainty of pooled estimates was measured with GRADE (Grading of Recommendations Assessment, Development, and Evaluation). RESULTS Of 86 eligible trials, 78 (N=11,505) were included in the meta-analysis. Regarding relapse prevention, most of the 12 LAIs included outperformed placebo. The largest point estimates and best rankings of LAIs compared with placebo were found for paliperidone (3-month formulation) and aripiprazole. Moderate to high GRADE certainty for superior relapse prevention compared with placebo was also found for (in descending ranking order) risperidone, pipothiazine, olanzapine, and paliperidone (1-month formulation). In head-to-head comparisons of LAIs, only haloperidol was inferior to aripiprazole, fluphenazine, and paliperidone. For acceptability, most LAIs outperformed placebo, with moderate to high GRADE certainty for (in descending ranking order) zuclopenthixol, aripiprazole, paliperidone (3-month formulation), olanzapine, flupenthixol, fluphenazine, and paliperidone (1-month formulation). In head-to-head comparisons, only LAI aripiprazole had superior acceptability to other LAIs (bromperidol, fluphenazine, paliperidone [1-month formulation], pipothiazine, and risperidone). CONCLUSIONS LAI formulations of paliperidone (3-month formulation), aripiprazole, olanzapine, and paliperidone (1-month formulation) showed the highest effect sizes and certainty of evidence for both relapse prevention and acceptability. Results from this network meta-analysis should inform frontline clinicians and guidelines.

Antipsychotic Adherence, Resource Use, and Costs Before and After the Initiation of Once-monthly Paliperidone Palmitate Therapy Among Medicaid Beneficiaries With Prior Schizophrenia Relapse. Clin Ther 2021; 43:535-548.

Abstract
PURPOSE Patients with schizophrenia often struggle with medication adherence and may benefit from the use of a long-acting injectable antipsychotic, including once-monthly paliperidone palmitate (PP1M), which was previously demonstrated to improve outcomes compared with oral antipsychotics. This study assessed the impact of initiating PP1M therapy on medication adherence, health care resource use (HRU), and costs among Medicaid beneficiaries with schizophrenia and a prior schizophrenia relapse. METHODS A 6-state Medicaid database (from quarter 1 of 2009 to quarter 1 of 2018) was used to identify adults with ≥2 schizophrenia diagnoses who started PP1M therapy on or after January 1, 2010. The index date was the first PP1M claim. Patients had ≥12 months of continuous Medicaid enrollment before and after the index date, ≥1 oral antipsychotic claim in the 12 months before the index date, and ≥1 relapse (proxied as a schizophrenia-related inpatient admission or emergency department [ED] visit) during the 12 months before the index date. Generalized estimating equations were used to compare adherence to antipsychotics (proportion of days covered ≥80%), HRU, and costs (reported in 2018 US dollars) in the 12 months after versus before the index date. Sensitivity analyses were conducted (1) accounting for the minimum and cumulative price inflation Medicaid rebates for pharmacy costs of branded psychiatric medications, (2) among patients with ≥2, ≥3, and ≥4 prior schizophrenia-related inpatient admissions or ED visits, (3) among patients not adherent to antipsychotic treatment before the index date, and (4) among patients switching to PP1M directly from oral risperidone or paliperidone. FINDINGS A total of 1725 patients met the study inclusion criteria (mean age, 39.5 years; 43% female). After versus before the index date, patients were 93% more likely to be adherent to antipsychotic treatment (P < 0.01). The likelihood of inpatient admissions and ED visits decreased by 89% and 49% (all P < 0.01) after initiating PP1M therapy. The number of inpatient days decreased by 31% (P < 0.01) and the number of ED visits by 16% (P = 0.03). Pharmacy costs increased by $514 per-patient-per-month (PPPM), whereas medical costs, driven by inpatient costs, decreased by $391 PPPM (all P < 0.01). Sensitivity analyses yielded similar trends. Notably, total health care cost savings of $231 PPPM were observed after accounting for the cumulative Medicaid rebate for costs of branded psychiatric medications (P < 0.01). IMPLICATIONS In Medicaid beneficiaries with relapsed schizophrenia, transitioning from oral antipsychotics to PP1M was associated with improved adherence to antipsychotics and decreased use of inpatient and ED services. Increased pharmacy costs after the initiation of PP1M were offset by decreased medical costs. After applying the cumulative Medicaid rebate, including the price inflation rebate for costs of branded psychiatric medications, initiation of PP1M therapy resulted in statistically significant health care cost savings.

Abstract
Schizophrenia is a serious mental illness that requires continuous and effective long-term management to reduce symptoms, improve quality of life, and prevent relapse. Oral antipsychotic medications have proven efficacy for many patients taking these medications; however, a considerable number of patients continue to experience ongoing symptoms and relapse, often due to lack of adherence. The advent of long-acting injectable (LAI) formulations of antipsychotic medications provided an opportunity to improve treatment adherence and overall patient outcomes. Despite data to support LAI efficacy, safety, and improved adherence over oral formulations, there are several misconceptions about and barriers to LAI implementation within a standard of care for patients with schizophrenia. Areas of resistance around LAIs include (1) doubts regarding their benefits outside of improved adherence, (2) questions regarding their prescribing to a broader population of patients with schizophrenia, (3) when to initiate LAIs, (4) concerns regarding the safety of LAIs in comparison with oral medication, and (5) the most effective ways to educate healthcare providers, patients, and caretakers to enable appropriate LAI consideration and acceptance. Here, we discuss these key controversies associated with LAIs and provide supportive evidence to facilitate LAI use in a manner that is constructive to the clinician-patient relationship and successful treatment.

The Effect of Switching to Long-Acting Injection (LAI) Antipsychotic Therapy on Patients with Schizophrenia. CURRENT HEALTH SCIENCES JOURNAL 2021; 47:237-248. [PMID: 34765244 PMCID: PMC8551897 DOI: 10.12865/chsj.47.02.14] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Figures] [Subscribe] [Scholar Register] [Received: 12/11/2020] [Accepted: 06/19/2021] [Indexed: 11/25/2022]
Abstract
MATERIAL AND METHOD We analyzed 362 patients with schizophrenia admitted during 2016 in an acute psychiatric ward and in a chronic psychiatric ward, diagnosed with paranoid or other schizophrenia, according to DSM-IV-TR, which, after remission of the symptoms of the acute episode, they benefited from antipsychotic therapy only in oral formulation. For some of these patients we instituted maintenance therapy with depot formulas. Patients were followed for up to two years. RESULTS Comparing the level of adherence to therapy, we found a statistically significant improvement, from 42.96% to 76.30%. Although we estimate that adherence to LAI therapy is over 90%, almost a quarter of patients have given up this type of treatment at some point due to side effects. Carrying out the comparative analysis of the number of hospitalizations per year, from the past and from the follow-up period, as well as of the scores registered at the scales used (PANSS, CGI, GAS, WHOQOL), in dynamics, we demonstrated the appearance of statistically significant changes. CONCLUSIONS the administration of antipsychotic therapy through LAI-type depot formulas can improve the therapeutic adherence of the patient with schizophrenia, thus improving the evolution of the disease and the quality of life.

Abstract
Antipsychotic long-acting formulations (LAI-AP) have emerged as a new therapeutic choice to treat patients presenting a severe mental disorder. Despite that, to date, there is a lack of safety data and studies regarding the use of LAI-AP formulations in pregnant women. Here we present the first six-case series of pregnant women with schizophrenia treated with aripiprazole-LAI reported in the literature. All patients remained psychopathologically stable through pregnancy and the postpartum period, and all of them were in treatment with aripiprazole-LAI. To date, all infants remain healthy with normal developmental milestones, without the presence of congenital malformations or adverse effects. Lack of information on safety data regarding the use of new antipsychotic formulations remains important in treating women with mental illness who desire to become pregnant. Further studies in this clinical population with a larger number of patients included remains necessary.

Effect of Paliperidone Palmitate 3-Month Formulation on Goal Attainment and Disability After 52 Weeks' Treatment in Patients with Clinically Stable Schizophrenia. Neuropsychiatr Dis Treat 2020; 16:3197-3208.

Abstract
PURPOSE This pragmatic clinical study aimed to assess goal attainment among patients with schizophrenia treated with paliperidone palmitate 3-monthly (PP3M) and its relation to their level of disability, and whether patients achieved symptomatic remission at the study endpoint. PATIENTS AND METHODS Goal attainment was assessed as a secondary endpoint using Goal Attainment Scaling (GAS) within a 52-week, prospective, single-arm, non-randomized, open-label, international, multicenter study evaluating the impact of transitioning stable patients with schizophrenia from paliperidone palmitate 1-monthly (PP1M) to PP3M. Additional exploratory analyses were performed to investigate the relationship between disability and functioning as measured by the World Health Organization Disability Assessment Schedule (WHODAS), Version 2.0, symptomatic remission, and goal attainment. RESULTS Overall, 305 patients were enrolled, of whom 281 (92.1%) provided GAS data at baseline. Of these, 160 achieved symptomatic remission at the last observation carried forward (LOCF) endpoint. The most common category of goals was "self" related, of which work-related was most frequent. Two-thirds of patients (67.7%) achieved at least one goal at the LOCF endpoint. Goal achievement was positively associated with lower baseline symptoms and symptomatic remission at LOCF endpoint, and with lower WHODAS scores at baseline and LOCF endpoint and greater WHODAS score improvements from baseline. Age, duration of disease, and duration of PP1M treatment before the switch did not impact goal setting and goal attainment. The proportion of patients with remunerated work status increased by 11.3% at LOCF endpoint. CONCLUSION The results of this secondary endpoint analysis indicate that continued treatment of patients with schizophrenia with PP3M following stabilization with PP1M may facilitate attainment of patients' personal goals and reduce disability, especially, but not exclusively, in patients with symptomatic remission achieved at LOCF.

Abstract
INTRODUCTION There are many possible treatment goals for patients with schizophrenia. Two major perspectives on treatment goals are the patient's and the physician's perspective. Patient-centered treatment mandates that an individual patient's treatment goals are taken into account when treatment is planned. In this narrative review, we address the commonalities and differences of the patient's and physician's perspectives. METHODS We searched for literature on treatment goals for patients with schizophrenia from the last 10 years. RESULTS Fifty-two relevant records were identified, 4 of which directly compare patient's and physician's perspectives. Two further articles used the same set of goals to ask patients or physicians for their assessment. DISCUSSION Agreement between patients and physicians regarding valuation of treatment goals was high. However, physicians tended to put more emphasis on the classical "textbook" goals of symptom resolution and functioning, while patients stressed well-being and quality of life more. Results on treatment goals from patients are difficult to generalize, since recruiting representative patient samples is challenging and patient subgroups may have differing priorities.

Abstract
The effect of antipsychotic medication is poor in 30-40% of patients with schizophrenia; treatment resistance is usually met with shifts to new drugs or drug augmentation strategies or a trial of clozapine. The purpose of this review was to examine the potential role of intestinal bacteria in the bioavailability of antipsychotic medication and the possibility that parenterally administered antipsychotics might be able to overcome treatment resistance. Databases were searched with appropriate terms to locate relevant papers dealing with the effect of antipsychotic drugs on the gut microbiome and the effect of bacterial metabolizing enzymes on antipsychotic drugs. Also searched were papers addressing the various current parenteral formulations of antipsychotic drugs. Sixty-five recent pertinent papers were reviewed and the results are suggestive of the premise that there is a drug refractory form of psychosis for which the composition of gut bacteria is responsible, and that parenteral drug administration could overcome the problem.

Differences in the Effectiveness of Long-Acting Injection and Orally Administered Antipsychotics in Reducing Rehospitalization among Patients with Schizophrenia Receiving Home Care Services. J Clin Med 2019; 8:jcm8060823. [PMID: 31181830 PMCID: PMC6617370 DOI: 10.3390/jcm8060823] [Citation(s) in RCA: 4] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/16/2019] [Revised: 05/30/2019] [Accepted: 06/05/2019] [Indexed: 01/08/2023] Open
Abstract
The current study explored the differences in the effectiveness of first and second generation long-acting injections and orally administered antipsychotics in reducing the rehospitalization rate among patients with schizophrenia receiving home care services in a medical center in Southern Taiwan. Longitudinal data between 1 January 2006, and 31 December 2015, were collected retrospectively. Patients were classified into three treatment groups: First generation antipsychotic (FGA) long-acting injection (LAI), second generation antipsychotic long-acting injection (SGA) (LAI), and oral antipsychotics. The primary outcomes were the rehospitalization rate and the follow-up time (duration of receiving home care services) until psychiatric rehospitalization. A total of 78 patients with schizophrenia were recruited. The average observation time was about 40 months. The oral treatment group tended to be older with a higher number of female patients and a lower level of education. The FGA treatment group tended to have a higher frequency and duration of hospitalization before receiving home care services. We found no significant differences in the follow-up time or psychiatric rehospitalization rate after receiving home care services among the three treatment groups. We propose that oral and LAI antipsychotics were equally effective when patients received home care services. Our results can serve as a reference for the choice of treatment for patients with schizophrenia in a home care program.
