Efficacy and acceptability of interventions to reduce antipsychotic polypharmacy: A systematic review and meta-analysis of randomized clinical trials. Schizophr Res 2024; 270:135-143. [PMID: 38908279 DOI: 10.1016/j.schres.2024.06.001] [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: 01/31/2024] [Revised: 05/26/2024] [Accepted: 06/03/2024] [Indexed: 06/24/2024]
Abstract
BACKGROUND Antipsychotic polypharmacy (APP) is frequent but evidence-based guidelines on reducing APP to antipsychotic monotherapy (APM) are sparse. We aimed to systematically review clinical interventions randomizing patients to reducing APP to APM versus continuing APP. METHODS Systematic literature review searching Medline and Embase (latest search January 10, 2024) for randomized clinical trials (RCTs) studying interventions comparing individuals randomized to reduction of APP to APM with individuals continuing on APP. Two independent reviewers performed the literature screening, data extraction, and risk of bias assessment (RoB2). We performed random effects meta-analyses on the main outcome all-cause discontinuation/"acceptability" of the treatment strategy and secondary outcomes change in psychopathology, functional level, and side effects. RESULTS The search identified 4672 hits, whereof 8 trials (N = 1204, 6 patient-level RCTs and 2 cluster-RCTs) were included, primarily in patients with schizophrenia. All trials were associated with high risk of bias. Compared to APP continuation, reduction to APM was associated with no significant change in all-cause discontinuation (studies = 6, n = 455, RR = 1.48, 95%CI = 0.74-2.95, I2 = 78 %) or inefficacy-related discontinuation (studies = 5, n = 351, RR = 1.60, 95%CI = 0.46-5.55, I2 = 70 %). Patients randomized to APM showed a trend towards greater reduction in psychopathology (studies = 5, n = 244, SMD = -0.24, 95%CI = -0.49, 0.02, I2 = 0 %) but no difference in functional level nor side effects. The cluster-RCTs found that interventions at the departmental level can result in lower rates of APP. CONCLUSION Although switching patients from APP to APM can be a viable approach, too few RCTs exist on this important topic. Clinicians need to evaluate potential benefits and risks of APP and APM on an individual basis. PROSPERO REGISTRATION CRD42022329955.

Abstract
PURPOSE/BACKGROUND It is still not well known whether antipsychotic monotherapy versus polypharmacy differs in terms of efficacy in the emergency department (ED) utilization, presentation with agitation/aggression, and rehospitalization in schizophrenia spectrum disorders (SSD) patients. This study aimed to determine the effectiveness of antipsychotic monotherapy and polypharmacy for these outcomes in the real world. METHODS/PROCEDURES The study was conducted with electronic health records of 669 SSD patients admitted to the ED. Patients were evaluated in 4 groups according to antipsychotic use at the first admission to ED: antipsychotic noncompliance for more than 90 days, antipsychotic noncompliance for 15 to 90 days, antipsychotic monotherapy, and polypharmacy. All patients followed up for at least 1 year after index admission. The primary outcomes determined an association between antipsychotic monotherapy versus polypharmacy and all-cause psychiatric hospitalization between the groups after index admission in the SSD. FINDINGS/RESULTS The groups, including patients with antipsychotic noncompliance, had higher ED visits, more hospitalizations, and more admissions with agitation/aggression compared with antipsychotic monotherapy or polypharmacy. However, no differences were found between monotherapy and polypharmacy groups regarding these outcomes. In addition, there was no difference in the risk of hospitalization in monotherapy antipsychotic users compared with polypharmacy users. Patients discharged with monotherapy or polypharmacy also had similar rehospitalization rates at follow-up. IMPLICATIONS/CONCLUSIONS There is no positive evidence that recommending polypharmacy over antipsychotic monotherapy is superior with regard to the resulting frequency of ED visits, ED admissions with agitation/aggression, hospitalization, and rehospitalization. In this context, antipsychotic monotherapy may be preferred over polypharmacy in patients who are not resistant to treatment.

[PMID: 37913621 DOI: 10.1016/j.psychres.2023.115575] [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: 05/24/2023] [Revised: 10/22/2023] [Accepted: 10/26/2023] [Indexed: 11/03/2023]
Abstract
The aim of this study was to identify the factors associated with antipsychotic polypharmacy (APP), investigate whether APP could affect the risk of rehospitalization, and explore temporal trends in APP use. Schizophrenia patients discharged from the study hospital between 2006 and 2021 (n = 16,722) were included in the analysis. The logistic regression model was employed to determine the predictors significantly associated with APP use. Survival analysis was used to compare time to rehospitalization between APP and antipsychotic monotherapy (AMT). The temporal trend of APP use was analyzed using the Cochran-Armitage Trend test. In comparison with the patients (n = 10,909) who were discharged on AMT, those (n = 5,813) on APP were significantly more likely to be male gender, to receive LAIs, to take clozapine, to take anticholinergic agents, to have a greater number of previous hospitalizations, and to have a higher CPZ equivalent dose of antipsychotic prescription. The prescription rate of APP significantly increased from 18.4 % in 2006 to 44.9 % in 2021. Compared with AMT, APP was associated with more clozapine use, more LAI use, higher doses of antipsychotics, and an increased risk of rehospitalization. In addition, the prescription of APP continued to increase during the study period.

Endocannabinoid Degradation Enzyme Inhibitors as Potential Antipsychotics: A Medicinal Chemistry Perspective. Biomedicines 2023; 11:biomedicines11020469. [PMID: 36831006 PMCID: PMC9953700 DOI: 10.3390/biomedicines11020469] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/09/2023] [Revised: 01/28/2023] [Accepted: 01/30/2023] [Indexed: 02/08/2023] Open
Abstract
The endocannabinoid system (ECS) plays a very important role in numerous physiological and pharmacological processes, such as those related to the central nervous system (CNS), including learning, memory, emotional processing, as well pain control, inflammatory and immune response, and as a biomarker in certain psychiatric disorders. Unfortunately, the half-life of the natural ligands responsible for these effects is very short. This perspective describes the potential role of the inhibitors of the enzymes fatty acid amide hydrolase (FAAH) and monoacylglycerol lipase (MGL), which are mainly responsible for the degradation of endogenous ligands in psychic disorders and related pathologies. The examination was carried out considering both the impact that the classical exogenous ligands such as Δ9-tetrahydrocannabinol (THC) and (-)-trans-cannabidiol (CBD) have on the ECS and through an analysis focused on the possibility of predicting the potential toxicity of the inhibitors before they are subjected to clinical studies. In particular, cardiotoxicity (hERG liability), probably the worst early adverse reaction studied during clinical studies focused on acute toxicity, was predicted, and some of the most used and robust metrics available were considered to select which of the analyzed compounds could be repositioned as possible oral antipsychotics.

The effect of long-acting injectable antipsychotic medications compared with oral antipsychotic medications among people with schizophrenia: A systematic review and meta-analysis. Int J Ment Health Nurs 2022; 31:469-535. [PMID: 34931437 DOI: 10.1111/inm.12964] [Citation(s) in RCA: 6] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/17/2021] [Revised: 11/22/2021] [Accepted: 12/06/2021] [Indexed: 11/29/2022]
Abstract
Long-acting injectable (LAI) antipsychotic medications may be an important modality of reducing costs, improving symptoms, and fostering quality of life outcomes for those with schizophrenia. Our objective was to systematically review and conduct a meta-analysis of the effectiveness of LAIs compared with oral antipsychotics on medication adherence, symptom remission/relapse, rehospitalization, outpatient visits, emergency department visits, healthcare costs, and social functioning. We performed a systematic search of PsycInfo, CINAHL, PubMed, and Scopus databases to examine studies meeting inclusion criteria prior to August 30th, 2020. Randomized controlled trials, retrospective studies, prospective studies among people with schizophrenia with at least 6-month follow-up data were obtained. Overall effect sizes and associated 95% confidence intervals (CI) were estimated with random-effects modeling. We found 75 articles meeting our inclusion criteria, including 341 730 individuals with schizophrenia. Systematic review results indicated that LAIs compared with orals improved medication adherence (25/29 studies), symptom remission/relapse (10/18 studies), rehospitalizations (26/49 studies), emergency department visits (9/17 studies), medical costs (11/15 studies), and social functioning (5/9 studies); however, LAIs also increased outpatient visits (7/16 studies) and pharmacy costs (10/10 studies). Meta-analytic results of studies with similar outcome measures did not find differences between LAIs and orals in respect to outcomes, except lowering emergency department visits and increasing pharmacy costs. The differences between the results of the narrative synthesis and the meta-analyses were possibly because of the low availability of studies with similar outcomes in the pooled analyses. Our overall results suggest that LAIs are at least comparable to orals in supporting important healthcare outcomes for those with schizophrenia. These findings support clinical practice in encouraging providers to prescribe LAIs when indicated.

Abstract
Few data exist regarding treatment with antipsychotics in forensic psychiatric patient populations with high social dangerousness. We performed a secondary analysis of 681 patients treated with at least one antipsychotic, extracted from a 1-year observational retrospective study, conducted on 730 patients treated in the Italian Residencies for Execution of Security Measures (REMS) (96.4% of the REMS population). We aimed at investigating antipsychotic polypharmacy (prescription of two or more concomitant antipsychotics) and high dose/very high-dose antipsychotics, as well as the possible factors associated with such therapeutic regimens. High dose/very high-dose antipsychotics were defined as a prescribed daily dose to WHO-defined daily dose ratio greater than 1.5 or 3.0, respectively. Binary logistic regression analysis was used in three models to test possible predictors of antipsychotic polypharmacy, high-dose antipsychotics, and very high-dose antipsychotic prescription. Antipsychotic polypharmacy resulted in n = 308 (45.2%) of the patients, n = 346 (50.8%) received high-dose antipsychotics, and n = 96 (14.1%) very high-dose antipsychotics. The multivariate analysis disclosed an association between antipsychotic polypharmacy and male gender (odds ratio (OR): 2.75 and 95% CI: 1.34–5.65), long-acting injectable (LAI) antipsychotic prescription (OR: 2.62 and 95% CI: 1.84–3.74), and aggressive behavior in REMS (OR: 1.63 and 95% CI: 1.13–2.36). High-dose antipsychotics were also associated with male gender (OR: 2.01 and 95% CI: 1.02–3.95), LAI antipsychotic prescription (OR: 2.78 and 95% CI: 1.95–3.97), and aggressive behavior in REMS (OR: 1.63 and 95% CI: 1.12–2.36). The use of antipsychotic polypharmacy and high-dose antipsychotics is frequent in the REMS population. These results might depend on regulatory and organizational aspects of the REMS system, including variability in structures, lack of a common model of care, and lack of stratified therapeutic security.
