Review
BACKGROUND
Pruritus is a symptom of several cholestatic liver diseases (CLDs) that can impair health-related quality of life (HRQoL). Despite evidence-based guideline therapy, managing cholestatic pruritus (CP) remains challenging, thus making the need for newer, more effective therapeutic agents more evident.
OBJECTIVE
Our study evaluated the efficacy of existing CP therapies.
DESIGN
Systematic review.
DATA SOURCES
From inception until March 2023, we conducted a comprehensive search of MEDLINE, Cochrane, EMBASE, Scopus, ClinicalTrial.gov, and other sources, including pharmaceutical webpages and conference proceedings published in English that reported on CP interventions.
METHODS
Two reviewers independently conducted screening and full-text review of articles with extraction conducted according to the Preferred Reporting Items for Systematic Reviews and Meta-Analysis (PRISMA) guidelines. The methodological quality of studies included in our qualitative synthesis was assessed by using the Cochrane ROBINS-I and ROBINS-II tools for interventional studies and the National Heart, Lung, and Blood Institute Quality Assessment Tool for Observational Cohort and Cross-Sectional Studies. The primary outcome assessed in our systematic review was the severity of CP after therapy.
RESULTS
Of 3293 screened articles, 92 studies were eligible for inclusion in the qualitative synthesis. Some patients' HRQoL improved with evidence-based standard therapy. Others, particularly those with severe and refractory CP, often required conversion to or addition of experimental noninvasive (e.g., ondansetron) or extracorporeal liver support to alleviate CP. In addition, studies investigating a newer class drug, the ileal bile acid transporter inhibitor (IBATi), demonstrate its effectiveness in reducing serum bile acid and alleviating CP with sustained improvement noted in patients with the inherited childhood cholestatic disorders - progressive familial intrahepatic cholestasis and Alagille syndrome.
CONCLUSION
Our findings consolidate data on the efficacy of guideline-based approaches and newer therapies for CP. While the initial findings are promising, additional clinical trials will be needed to determine the full extent of IBATi's efficacy and potential use in treating other common CLDs. These results provide a foundation for future research and highlight the need for continued investigation into the management and treatment of CLDs.

BACKGROUND
Ondansetron is a selective 5-hydroxytryptamine type 3 serotonin-receptor antagonist with antiemetic properties used inadvertently in the emergency department for controlling nausea. However, ondansetron is linked with a number of adverse effects, including prolongation of the QT interval. Therefore, the purpose of this meta-analysis was to assess the occurrence of QT prolongation in pediatric, adult, and elderly patients receiving oral or intravenously administered ondansetron.
METHODS
A thorough electronic search was conducted on PubMed (Medline) and Cochrane Library from the databases' inception to August 10, 2022. Only those studies were considered in which ondansetron was administered orally or intravenously to participants for the treatment of nausea and vomiting. The prevalence of QT prolongation in multiple predefined age groups was the outcome variable. Analyses were conducted using Review manager 5.4 (Cochrane collaboration, 2020).
RESULTS
A total of 10 studies involving 687 ondansetron group participants were statistically analyzed. The administration of ondansetron was associated with a statistically significant prevalence of QT prolongation in all age groups. An age-wise subgroup analysis was conducted which revealed that the prevalence of QT prolongation among participants younger than 18 years was not statistically significant, whereas it was statistically significant among participants aged 18-50 years and among patients older than 50 years.
CONCLUSIONS
The present meta-analysis provides further evidence that oral or intravenous administration of Ondansetron may lead to QT prolongation, particularly among patients older than 18 years of age.

Review
In a generation where advancements in research and understanding have led to remarkable achievements in medicine, it is still unfathomable that, after more than a century, the cause of schizophrenia is still a mystery. While antipsychotics, without a doubt, have brought on an exemplary revolution in the way psychiatric disorders are now treated, there are still imperative deficits that need to be addressed to ultimately enable individuals with schizophrenia to function normally in society. However, without a definite cause of schizophrenia, even though speculation has been made on its inflammatory and neurodegenerative nature, it has provided an unnecessary hindrance to finding further potential treatment modalities for these patients. Nevertheless, some trials are investigating potential adjunctive treatment regimens to antipsychotics, which can help achieve complete remission. Exploring these drugs will have significant implications for managing schizophrenia in future clinical practices. This systematic review was conducted between January 2012 to July 2022 according to Preferred Reporting Items for Systematic Review and Meta-Analysis guidelines to evaluate the safety and efficacy of ondansetron and simvastatin as adjunctive treatment to antipsychotics in adult patients with schizophrenia. This review included nine randomized controlled trials. Overall, both simvastatin and ondansetron, when used as adjunctive treatment in schizophrenia, appear to be safe. Ondansetron showed promising results, with all studies on this drug showing positive overall results on schizophrenia symptoms. On the other hand, simvastatin demonstrated mixed results, which can be attributed to the limited participants in the studies and the shorter duration of the trials. However, more extensive trials with uniform assessment tools are needed to demonstrate concrete evidence of the effectiveness of these drugs, whether alone or in combination with each other or perhaps another drug such as aspirin in schizophrenia.

Meta-Analysis
OBJECTIVE
Propofol is the most commonly used intravenous anesthetic medication and is most commonly associated with post-operative pain. Several drugs are investigated to reduce post-operative pain caused by propofol injection. Ondansetron is a potent anti-emetic drug showing promising results as an analgesic. This meta-analysis aims to compare the efficacy of ondansetron to placebo and lidocaine in reducing post-operative pain caused by propofol injection.
METHODS
PubMed, Embase, Cochrane Library, Web of Science, and Scopus were searched for relevant randomized controlled trials (RCTs) till May 2022. We conducted a meta-analysis using RevMan software version 5.4, and we assessed the quality of included RCTs using the Cochrane risk of bias tool.
RESULTS
In our study, we included 23 RCTs with 2957 participants. Compared to placebo, ondansetron significantly increased the rate of no pain [risk ratio (RR) = 2.36, 95% confidence interval (CI) (1.39-4.01)], and reduced moderate [RR = 0.39, 95% CI (0.30-0.52)] and severe pain [RR = 0.34, 95% CI (0.24-0.50)]. Furthermore, ondansetron significantly reduced PONV [RR = 0.73, 95% CI (0.58, 0.91)]. On the other hand, ondansetron showed an inferior efficacy to lidocaine regarding the incidence of no, moderate, and severe pain.
CONCLUSION
Ondansetron is effective in reducing post-operative propofol-induced pain. However, lidocaine is more effective than it.

Ondansetron is a selective serotonin (5HT3) receptor antagonist that is under evaluation as an adjunctive treatment for schizophrenia, and a novel treatment for hallucinations in Parkinson's disease. Ondansetron reverses sensory gating deficits and improves visuoperceptual processing in animal models of psychosis, but it is unclear to what extent preclinical findings have been replicated in humans. We systematically reviewed human studies that evaluated the effects of ondansetron and other 5HT3 receptor antagonists on sensory gating deficits or sensory processing. Of 11 eligible studies, eight included patients with schizophrenia who were chronically stable on antipsychotic medication; five measured sensory gating using the P50 suppression response to a repeated auditory stimulus; others included tests of visuoperceptual function. Three studies in healthy participants included tests of visuoperceptual and sensorimotor function. A consistent and robust finding (five studies) was that ondansetron and tropisetron (5HT3 antagonist and α7-nicotinic receptor partial agonist) improved sensory gating in patients with schizophrenia. Tropisetron also improved sustained visual attention in non-smoking patients. There was inconsistent evidence of the effects of 5HT3 antagonists on other measures of sensory processing, but interpretation was limited by the small number of studies, methodological heterogeneity and the potential confounding effects of concomitant medication in patients. Despite these limitations, we found strong evidence that selective 5HT3 antagonists (with or without direct α7-nicotinic partial agonist effects) improved sensory gating. Future studies should investigate how this relates to potential improvement in neurocognitive symptoms in antipsychotic naive patients with prodromal or milder symptoms, in order to understand the clinical implications.

Drugs & Aging Dec 2023To reduce prescribing cascades occurring in clinical practice, healthcare providers require information on the prescribing cascades they can recognize and prevent. (Review)
Review
BACKGROUND
To reduce prescribing cascades occurring in clinical practice, healthcare providers require information on the prescribing cascades they can recognize and prevent.
OBJECTIVE
This systematic review aims to provide an overview of prescribing cascades, including dose-dependency information and recommendations that healthcare providers can use to prevent or reverse them.
METHODS
The Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) was followed. Relevant literature was identified through searches in OVID MEDLINE, OVID Embase, OVID CINAHL, and Cochrane. Additionally, Web of Science and Scopus were consulted to analyze reference lists and citations. Publications in English were included if they analyzed the occurrence of prescribing cascades. Prescribing cascades were included if at least one study demonstrated a significant association and were excluded when the adverse drug reaction could not be confirmed in the Summary of Product Characteristics. Two reviewers independently extracted and grouped similar prescribing cascades. Descriptive summaries were provided regarding dose-dependency analyses and recommendations to prevent or reverse these prescribing cascades.
RESULTS
A total of 95 publications were included, resulting in 115 prescribing cascades with confirmed adverse drug reactions for which at least one significant association was found. For 52 of these prescribing cascades, information regarding dose dependency or recommendations to prevent or reverse prescribing cascades was found. Dose dependency was analyzed and confirmed for 12 prescribing cascades. For example, antipsychotics that may cause extrapyramidal syndrome followed by anti-parkinson drugs. Recommendations focused on dosage lowering, discontinuing medication, and medication switching. Explicit recommendations regarding alternative options were given for three prescribing cascades. One example was switching to ondansetron or granisetron when extrapyramidal syndrome is experienced using metoclopramide.
CONCLUSIONS
In total, 115 prescribing cascades were identified and an overview of 52 of them was generated for which recommendations to prevent or reverse them were provided. Nonetheless, information regarding alternative options for managing prescribing cascades was scarce.

Hyperemesis gravidarum is a serious pregnancy complication that affects approximately 1% of pregnancies worldwide. To determine whether the use of ondansetron during pregnancy is associated with abnormal pregnancy outcomes. PubMed, Cochrane Library, CINAHL, Embase, CNKI, CBM, WANFANG, and ClinicalTrials.gov were searched for citations published in any language from inception to 15 December 2021. Eligible studies included any observational study. Odds ratio (OR) and 95% confidence interval (CI) were used as indicators to examine the association between ondansetron and abnormal pregnancy outcomes. Twenty articles from 1,558 citations were included. Our preliminary analysis showed that compared with the unexposed group, the use of ondansetron during pregnancy may be associated with an increased incidence of cardiac defects (OR = 1.06, 95% CI: 1.01-1.10), neural tube defects (OR = 1.12, 95% CI: 1.05-1.18), and chest cleft (OR = 1.21, 95% CI: 1.07-1.37). Further sensitivity analysis showed no significant association between ondansetron and cardiac defects (OR = 1.15,95% CI: 0.94-1.40) or neural tube defects (OR = 0.87,95% CI: 0.46-1.66). When controversial studies were eliminated, the results for the chest defects disappeared. Simultaneously, we found that the use of ondansetron was associated with a reduced incidence of miscarriage (OR = 0.53, 95% CI: 0.31-0.89). Ondansetron was not associated with orofacial clefts (OR = 1.09,95% CI: 0.95-1.25), spinal limb defects (OR = 1.14,95% CI: 0.89-1.46), urinary tract deformities (OR = 1.06,95% CI: 0.97-1.15), any congenital malformations (OR = 1.03,95% CI: 0.98-1.09), stillbirth (OR = 0.97,95% CI: 0.83-1.15), preterm birth (OR = 1.22,95% CI: 0.80-1.85), neonatal asphyxia (OR = 1.05,95% CI: 0.72-1.54), or neonatal development (OR = 1.18,95% CI: 0.96-1.44) in our primary analysis. In our analysis, using ondansetron during pregnancy was not associated with abnormal pregnancy outcomes. Although our study did not find sufficient evidence of ondansetron and adverse pregnancy outcomes, future studies including the exposure period and dose of ondansetron, as well as controlling for disease status, may be useful to truly elucidate the potential risks and benefits of ondansetron.

Review
Hypotension induced by spinal anaesthesia is a common clinical complication associated with multiple perioperative adverse events. We conducted a systemic review and meta-analysis to confirm whether ondansetron could alleviate hypotension following spinal anaesthesia. PubMed, Embase, Web of Science, and Cochrane Library were searched to identify eligible randomised controlled trials from their respective database inception dates to 30 September 2022. The primary outcome of the meta-analysis was the incidence of hypotension after spinal anaesthesia. The risk of bias in the included studies was evaluated using the revised Cochrane risk of bias tool for randomised trials (RoB 2.0). Grading of Recommendations, Assessment, Development, and Evaluation was applied to assess the level of certainty. A total of 25 studies were included in this research. The meta-analysis revealed that ondansetron significantly decreased the incidence of hypotension (RR = 0.65, 95% CI 0.53−0.80, p < 0.01, I2 = 64%) and bradycardia. In addition, patients treated with ondansetron had a reduced need for vasopressors administration. This study suggests that ondansetron may be recommended as a prophylaxis for hypotension and bradycardia following spinal anaesthesia; the level of evidence was moderate with a high level of heterogeneity.

Journal of Perianesthesia Nursing :... Feb 2022Evaluate the efficacy of ondansetron in preventing shivering after spinal anesthesia in cesarean delivery. (Meta-Analysis)
Meta-Analysis
PURPOSE
Evaluate the efficacy of ondansetron in preventing shivering after spinal anesthesia in cesarean delivery.
DESIGN
Systematic review and meta-analysis METHODS: Following the PRISMA statement, PubMed, CINAHL, Cochrane, EMBASE, Google scholar and other grey literature databases were searched for eligible studies.
FINDINGS
The overall incidence of shivering after spinal anesthesia in cesarean delivery is 32%, with 24% in patients who received ondansetron compared to 40% in the placebo group. A total of 19 trials consisting of 1399 patients were evaluated. Compared to placebo, ondansetron is effective in reducing the incidence of shivering (RR, 0.47; 95% CI, 0.29 to 0.78; P = 0.003). The quality of evidence is low due to substantial heterogeneity, imprecision and suspected publication bias. Patients who received ondansetron are less likely to require rescue treatment for shivering (RR, 0.34; 95% CI, 0.15 to 0.76; P = 0.009). Also, ondansetron is associated with a lower incidence of hypotension necessitating vasopressor treatment, and nausea and vomiting with no effects on the incidence of bradycardia.
CONCLUSION
Ondansetron is effective in mitigating shivering after spinal anesthesia in cesarean delivery.

Review
PURPOSE
Mild traumatic brain injury (mTBI) is a global public health problem and its current management is limited to rest and symptom management. Despite frequent use of drugs for symptom control, there is a lack of consensus on the optimal pharmacological management of post-concussive symptoms. We reviewed the relevant literature to compile the evidence about the pharmaceutical management of pediatric mTBI.
METHODS
We performed a systematic review of the literature available in PubMed, Cochrane CENTRAL, and ClinicalTrials.Gov as well as through citation tracing. A modified PICO framework was used for the construction of search strategy and eligibility criteria. Risk of bias was assessed using RoB-2 tool for randomized and ROBINS-I for non-randomized studies.
RESULTS
A total of 6260 articles were screened for eligibility. After exclusions, a total of 88 articles received full text review. A total of 15 reports representing 13 studies (5 randomized clinical trials, 1 prospective randomized cohort study, 1 prospective cohort study, and 6 retrospective cohort studies) met the eligibility criteria and were included in the review. We identified 16 pharmacological interventions in a total of 931 pediatric patients with mTBI. Amytriptiline (n = 4), ondansetron (n = 3), melatonin (n = 3), metoclopramide (n = 2), magnesium (n = 2), and topiramate (n = 2) were investigated in multiple studies. All RCTs were relatively of small size (n ≤ 33/group).
CONCLUSION
The available evidence supporting pharmacological intervention in pediatric mild traumatic brain injury is scarce. We propose a framework to facilitate future collaborative research efforts to test and validate various pharmacological interventions for acute and persistent post-concussive symptoms in children.
