Optimisation of pharmacotherapy in psychiatry through therapeutic drug monitoring, molecular brain imaging and pharmacogenetic tests: focus on antipsychotics. World J Biol Psychiatry 2024:1-123. [PMID: 38913780 DOI: 10.1080/15622975.2024.2366235] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/04/2023] [Accepted: 06/06/2024] [Indexed: 06/26/2024]
Abstract
BACKGROUND For psychotic disorders (i.e. schizophrenia), pharmacotherapy plays a key role in controlling acute and long-term symptoms. To find the optimal individual dose and dosage strategy, specialized tools are used. Three tools have been proven useful to personalize drug treatments: therapeutic drug monitoring (TDM) of drug levels, pharmacogenetic testing (PG), and molecular neuroimaging. METHODS In these Guidelines, we provide an in-depth review of pharmacokinetics, pharmacodynamics, and pharmacogenetics for 50 antipsychotics. Over 30 international experts in psychiatry selected studies that have measured drug concentrations in the blood (TDM), gene polymorphisms of enzymes involved in drug metabolism, or receptor/transporter occupancies in the brain (positron emission tomography (PET)). RESULTS Study results strongly support the use of TDM and the cytochrome P450 (CYP) genotyping and/or phenotyping to guide drug therapies. Evidence-based target ranges are available for titrating drug doses that are often supported by PET findings. CONCLUSION All three tools discussed in these Guidelines are essential for drug treatment. TDM goes well beyond typical indications such as unclear compliance and polypharmacy. Despite its enormous potential to optimize treatment effects, minimize side effects and ultimately reduce the global burden of diseases, personalized drug treatment has not yet become the standard of care in psychiatry.

Abstract
BACKGROUND Risperidone is the first new-generation antipsychotic drug made available in the market in its generic form. OBJECTIVES To determine the clinical effects, safety and cost-effectiveness of risperidone compared with placebo for treating schizophrenia. SEARCH METHODS On 19th October 2015, we searched the Cochrane Schizophrenia Group Trials Register, which is based on regular searches of CINAHL, BIOSIS, AMED, EMBASE, PubMed, MEDLINE, PsycINFO, and registries of clinical trials. We checked the references of all included studies and contacted industry and authors of included studies for relevant studies and data. SELECTION CRITERIA Randomised clinical trials (RCTs) comparing oral risperidone with placebo treatments for people with schizophrenia and/or schizophrenia-like psychoses. DATA COLLECTION AND ANALYSIS Two review authors independently screened studies, assessed the risk of bias of included studies and extracted data. For dichotomous data, we calculated the risk ratio (RR), and the 95% confidence interval (CI) on an intention-to-treat basis. For continuous data, we calculated mean differences (MD) and the 95% CI. We created a 'Summary of findings table' using GRADE (Grading of Recommendations Assessment, Development and Evaluation). MAIN RESULTS The review includes 15 studies (N = 2428). Risk of selection bias is unclear in most of the studies, especially concerning allocation concealment. Other areas of risk such as missing data and selective reporting also caused some concern, although not affected on the direction of effect of our primary outcome, as demonstrated by sensitivity analysis. Many of the included trials have industry sponsorship of involvement. Nonetheless, generally people in the risperidone group are more likely to achieve a significant clinical improvement in mental state (6 RCTs, N = 864, RR 0.64, CI 0.52 to 0.78, very low-quality evidence). The effect withstood, even when three studies with >50% attrition rate were removed from the analysis (3 RCTs, N = 589, RR 0.77, CI 0.67 to 0.88). Participants receiving placebo were less likely to have a clinically significant improvement on Clinical Global Impression scale (CGI) than those receiving risperidone (4 RCTs, N = 594, RR 0.69, CI 0.57 to 0.83, very low-quality evidence). Overall, the risperidone group was 31% less likely to leave early compared to placebo group (12 RCTs, N = 2261, RR 0.69, 95% CI 0.62 to 0.78, low-quality evidence), but Incidence of significant extrapyramidal side effect was more likely to occur in the risperidone group (7 RCTs, N = 1511, RR 1.56, 95% CI 1.13 to 2.15, very low-quality evidence).When risperidone and placebo were augmented with clozapine, there is no significant differences between groups for clinical response as defined by a less than 20% reduction in PANSS/BPRS scores (2 RCTs, N = 98, RR 1.15, 95% CI 0.93 to 1.42, low-quality evidence) and attrition (leaving the study early for any reason) (3 RCTs, N = 167, RR 1.13, 95% CI 0.53 to 2.42, low quality evidence). One study measured clinically significant responses using the CGI, no effect was evident (1 RCT, N = 68, RR 1.12 95% CI 0.87 to 1.44, low quality evidence). No data were available for extrapyramidal adverse effects. AUTHORS' CONCLUSIONS Based on low quality evidence, risperidone appears to be benefitial in improving mental state compared with placebo, but it also causes more adverse events. Eight out of the 15 included trials were funded by pharmaceutical companies. The currently available evidence isvery low to low quality.

Abstract
BACKGROUND Zuclopenthixol is an older antipsychotic that has three distinct formulations (zuclopenthixol dihydrochloride, zuclopenthixol acetate or Acuphase and zuclopenthixol decanoate). Although it has been in common use for many years no previous systematic review of its efficacy compared to placebo in schizophrenia has been undertaken. OBJECTIVES To evaluate the effectiveness of all formulations of zuclopenthixol when compared with a placebo in schizophrenia. SEARCH METHODS On 6 November 2013 and 20 October 2015, we searched the Cochrane Schizophrenia Group Trials Register, which is based on regular searches of MEDLINE, EMBASE, CINAHL, BIOSIS, AMED, PubMed, PsycINFO, and registries of clinical trials. We also checked the references of all included studies and contacted authors of included studies for relevant studies and data. SELECTION CRITERIA We included all randomised controlled trials comparing zuclopenthixol of any form with placebo for treatment of schizophrenia or schizophrenia-like psychoses. DATA COLLECTION AND ANALYSIS We extracted and cross-checked data independently. We identified only a small number of studies so we cross checked all studies. We calculated fixed-effect relative risks (RR) and 95% confidence intervals (CI) for dichotomous data. We analysed by intention-to-treat. Where possible we converted continuous outcomes into dichotomous outcomes. When this was not possible we used mean differences (MD) for continuous variables. We assessed risk of bias for included studies and used GRADE (Grading of Recommendations Assessment, Development and Evaluation) to create a 'Summary of findings' table. MAIN RESULTS Only two studies, with a total of 65 participants, were eligible for inclusion in the review. Overall the quality of the two studies was low, with small study populations and significant sources of bias, so we were not able to use all the data in our comparisons. . The studies were old from 1968 and 1972, and would be unlikely to pass modern peer review standard. We were only able to find short-term data and only trials randomising zuclopenthixol dihydrochloride. We also hoped to identify data for zuclopenthixol acetate versus placebo and zuclopenthixol decanoate versus placebo comparisons. We were unable to identify any studies that included data on these two fairly widely used drugs.For our primary outcome of interest, clinically significant improvement, we found one study that provided useable data. Global state measured by clinical global impression scale (CGI) improvement showed different ratings when assessed by a psychiatrist or a nurse.The psychiatrist scores failed to achieve statistical significance, however when assessed by nursing staff, the difference favouring zuclopenthixol did reach statistical significance (1 RCT n = 29, RR 2.57 95% CI 1.06 to 6.20, very low quality data). There was also evidence of increased sedation with those treated with zuclopenthixol when compared with placebo (1 RCT n = 29, RR 4.67 95% CI 1.23 to 17.68, very low quality data). 'Leaving the study early' data were equivocal. No useable data were available for outcomes such as relapse, mental state, death, quality of life, service use or economic costs. AUTHORS' CONCLUSIONS For people with schizophrenia this review shows that zuclopenthixol dihydrochloride may help with the symptoms of schizophrenia. The review provides some trial evidence that, if taking zuclopenthixol dihydrochloride, people may experience some adverse effects and sedation compared with placebo. However this evidence is of very low quality and with some significant sources of bias. There are no data for zuclopenthixol decanoate or zuclopenthixol acetate.For clinicians, the available trial data on the absolute effectiveness of zuclopenthixol dihydrochloride do support its use but the limited nature of the data and significant sources of bias make conclusions hard to draw. Zuclopenthixol in all three forms is a commonly used antipsychotic and it is disappointing that there are so few data regarding its use.

Abstract
BACKGROUND The new generation antipsychotics are associated with a lower risk of adverse effects compared with drugs such as haloperidol. Many treatment guidelines recommend the use of new generation ('atypical') antipsychotic drugs for people with a first episode of schizophrenia. OBJECTIVES To examine the effects of the new generation antipsychotics for people with a first episode of schizophrenia or schizophrenia-like psychoses. SEARCH STRATEGY The reviewers searched the Cochrane Schizophrenia Group's register (March 2002) and the included and excluded studies tables of relevant Cochrane reviews, references of all relevant studies, contacted industry and authors of relevant studies to identify further trials. SELECTION CRITERIA Randomised clinical trials comparing new generation antipsychotics (amisulpride, clozapine, olanzapine, quetiapine, risperidone, sulpiride, ziprasidone, zotepine) with conventional antipsychotics for people with a first episode of schizophrenia or schizophrenia-like psychoses. DATA COLLECTION AND ANALYSIS Citations and, where possible, abstracts were independently inspected by three reviewers, papers ordered, re-inspected and quality assessed. We independently extracted data but excluded them if loss to follow up was greater than 50%. For homogeneous dichotomous data, we calculated the relative risk (RR), the 95% confidence interval (CI) and, where appropriate, the number needed to treat (NNT), on an intention-to-treat basis. For continuous data, reviewers calculated weighted mean differences (WMD). MAIN RESULTS We include two short-term studies (total n=266), one of which was a report of a sub-group of a larger study. One compared risperidone with an average of 6 mg/day haloperidol and the other olanzapine with an average of 11 mg/day haloperidol. Compared with olanzapine, significantly more people receiving haloperidol left the study early (n=83, 1 RCT, RR 0.43 CI 0.3 to 0.7, NNH 3 CI 2 to 8). This was not so for the risperidone versus haloperidol comparison (n=183, 1 RCT, RR=0.7 CI 0.4 to 1.1). In terms of global effects, studies reported no differences between risperidone and haloperidol (n=183, RR not much improved 1.0 CI 0.6 to 1.5), and olanzapine and the same control (n=83, RR needing at least one dose of benzodiazepine 0.8 CI 0.5 to 1.1). More people allocated to olanzapine had clinically significant improvement in mental state compared with those given haloperidol (n=83, RR no 'clinically significant improvement' 0.45 CI 0.3 to 0.7, NNH 3 CI 2 to 6). In the risperidone study, however, no such difference was apparent (n=183, RR 'no clinically significant improvement in mental state' 0.85 CI 0.6 to 1.2). Significantly more people given haloperidol (4-16mg) experienced at least one adverse event when compared with risperidone (4-16mg) (n=183, RR 0.9 CI 0.8 to 0.98, NNH 8 CI 4 to 50). Use of anticholinergic medication for extrapyramidal adverse events was less prevalent for people allocated either olanzapine (n=83, RR 0.3 CI 0.2 to 0.7, NNH 4 CI 2 to 14) or risperidone (n=183, RR 0.7 CI 0.5 to 0.9, NNH 4 CI 3 to 9) compared with those given haloperidol. There are no data at all on outcomes such as compliance, cost, social and cognitive functioning, relapse, rehospitalisation, or quality of life. There are no medium to long-term data. Eight ongoing studies may provide more information. REVIEWER'S CONCLUSIONS The results of this review are inconclusive. Whether the use of new generation antipsychotics really makes the treatment less off putting and enhances long-term compliance is unclear. Pragmatic, well-designed and reported long-term trials would be useful to answer this question.
