RESUMO
BACKGROUND: In 2017, we published an article addressing drug shortages (DS) in Israel, exploring regulatory perspectives, challenges, and potential solutions. Since then, DS remain a significant concern for patients, healthcare providers, and policymakers globally. In this updated article, we revisit the topic, providing new insights, data, and analysis on the current DS landscape in Israel, efforts to mitigate them, and propose strategies to combat this escalating issue. METHODS: We conducted a comprehensive search of the Israeli Ministry of Health (MOH) DS database, spanning from 2014 to the present. We extracted DS numbers and their reasons. Further searches on the Israeli MOH website, pharmaceutical division archives, and the internet yielded official MOH publications and correspondence regarding regulatory responses to DS from 2017 onwards. Additionally, two specific cases of DS were examined to analyze their handling. Recent activities and publications from the Israeli MOH aimed at reducing DS were also reviewed. RESULTS: Between 2014 and 2022, DS surged 2.66-fold. Total DS were 3228; 672 due to commercial reasons, and 2556 to operational reasons (20.5% and 79.5% respectively). The average duration of intermittent DS increased 1.56-fold, from 85 to 133 days. Manufacturers informed the MOH 22 days prior to actual shortage on average. Analyzing 2022's DS (640) by ATC groups, prominent categories included nervous system drugs (18%), drugs acting on the alimentary tract and metabolism (14%), and dermatologicals (11%). Operational DS in 2022 (n = 564) were primarily due to stock delivery delays (38%), stock over-utilization (12%), and raw material shortages (9%). Sixteen official MOH publications on DS were identified from 2017 onwards. Moreover, two high-impact DS case studies were examined. CONCLUSION: Despite routine monitoring by the Israeli MOH and updating the DS policy throughout this period, DS persist, intensifying annually and posing serious health risks. This trend mirrors international patterns, affecting countries globally. In Israel's uniquely structured healthcare system, with its swift stakeholder cooperation and implementation capabilities, more effective DS management is conceivable. We propose ten universally applicable rules to address DS challenges.

OBJECTIVES: US FDA and EMA allow facilitated regulatory pathways to expedite access to new treatments. Limited supportive data may result in major postapproval variations. In Israel, partly relying on Food and Drug Administration (FDA) and European Medicines Agency (EMA), clinical data are reviewed independently by the Advisory Committee of Drug Registration (ACDR). In this study, the correlation between the number of discussions at the ACDR and major postapproval variations is examined. DESIGN: This is an observational retrospective comparative cohort study. SETTING: Applications with FDA and/or EMA approval at time of assessment in Israel were included. The timeframe was chosen to allow a minimum of 3 years of postmarketing approval experience for potential major label variations. Data regarding the number of discussions at ACDR were extracted from protocols. Data on postapproval major variations were extracted from the FDA and EMA websites. RESULTS: Between 2014 and 2016, 226 (176 drugs) applications, met the study criteria. 198 (87.6%) and 28 (12.4%) were approved following single and multiple discussions, respectively. A major postapproval variation was recorded in 129 (65.2%) compared with 23 (82.1%) applications approved following single and multiple discussions, respectively (p=0.002). Increased risk for major variation was found for medicines approved following multiple discussions (HR=1.98, 95% CI: 1.26 to 3.09) with a median time of 1.2 years, applications approved based on phase II trials (HR=2.58, 95% CI: 1.72 to 3.87), surrogate endpoints (HR=1.99, 95% CI: 1.44 to 2.74) and oncologic indications (HR=2.48, 95% CI: 1.78 to 3.45). CONCLUSIONS: Multiple ACDR discussions associated with limited supportive data are predictive for major postapproval variations. Moreover, our findings demonstrate that approval by the FDA and/or EMA does not pave the way to automatic approval in Israel. In a substantial per cent of the cases, submission of the same clinical data resulted in different safety and efficacy considerations, requiring additional supporting data in some cases or even rejection of the application in others.

AIMS: Over the past several decades, many antiobesity drugs have been withdrawn from the market due to unanticipated adverse events, often involving cardiotoxicity. This study aimed to evaluate the presence of cardiovascular safety signals with currently marketed antiobesity drugs. METHODS: We used the US Food and Drug Administration Adverse Event Reporting System (FAERS) database and retrieved data from January 2013 through December 2018. We performed disproportionality analyses to detect cardiovascular safety signals with three antiobesity drugs recently approved for marketing: lorcaserin, naltrexone-bupropion, phentermine, and phentermine-topiramate. Three main cardiovascular outcomes were evaluated: valvular disorders, and pulmonary hypertension (PH) and other cardiovascular events (myocardial infarction, stroke, cardiovascular death, cardiac failure, and arrhythmia). RESULTS: During the evaluated period, a total of 6,787,840 adverse event reports were submitted to FAERS. Of these, 2687 involved lorcaserin, 3960 involved phentermine/phentermine-topiramate, and 2873 involved naltrexone-bupropion. Lorcaserin was associated with a significantly greater proportion of reports of valvular disorders (ROR = 4.39; 95% CI 2.72-5.07). None of the antiobesity drugs were associated with a safety signal for valvulopathy, PH, or other cardiovascular events. CONCLUSIONS: Our analyses revealed a signal for valvular disorders with lorcaserin and did not detect a safety signal for other cardiovascular events with recently approved antiobesity drugs. Further research is needed to explore and validate this signal.

BACKGROUND: There is a marked increase in the use of selective serotonin reuptake inhibitors and serotonin norepinephrine reuptake inhibitors in the last decade. Many newborns are likely to be exposed during pregnancy and labor. OBJECTIVE: We aimed to evaluate the association between exposure to selective serotonin reuptake inhibitors and serotonin norepinephrine reuptake inhibitors during pregnancy and the risk for persistent pulmonary hypertension of the newborn. We sought to compare the risk for persistent pulmonary hypertension of the newborn between specific selective serotonin reuptake inhibitor agents. STUDY DESIGN: MEDLINE, Embase, and Cochrane were searched up to July 2017. No language restrictions were applied. Search key words included: "SSRI," "SNRI," "pregnancy," "risk," "new-born," and "pulmonary hypertension." Retrospective cohort studies and case-control studies reporting the risk for persistent pulmonary hypertension of the newborn in the offspring of women exposed to selective serotonin reuptake inhibitors or serotonin norepinephrine reuptake inhibitors during pregnancy, were extracted. Two independent researchers identified relevant data. Random effects meta-analysis was used to pool results. Odds ratios were calculated with subsequent 95% confidence intervals. Network meta-analysis was conducted, incorporating direct and indirect comparisons among different selective serotonin reuptake inhibitors. The primary outcome was risk for persistent pulmonary hypertension of the newborn after exposure to selective serotonin reuptake inhibitors or serotonin norepinephrine reuptake inhibitors during pregnancy. RESULTS: A total of 11 studies were identified. A total of 156,978 women and their offspring were exposed to selective serotonin reuptake inhibitors or serotonin norepinephrine reuptake inhibitors during pregnancy. Persistent pulmonary hypertension of the newborn was detected among 452 exposed offspring, representing an incidence rate of 2.9 cases per 1000 live births and a number needed to harm of 1000. The risk for persistent pulmonary hypertension of the newborn was significantly increased in the analysis of exposure to selective serotonin reuptake inhibitor/serotonin norepinephrine reuptake inhibitor in any trimester (odds ratio, 1.82; 95% confidence interval, 1.31-2.54; I2 = 72%), as well as in analysis restricted to exposure week >20 (odds ratio, 2.08; 95% confidence interval, 1.44-3.01; I2 = 76%). In network meta-analysis, sertraline was ranked most likely to have the lowest risk for persistent pulmonary hypertension of the newborn among the different selective serotonin reuptake inhibitors (P = .83). CONCLUSION: Exposure to selective serotonin reuptake inhibitors or serotonin norepinephrine reuptake inhibitors during pregnancy is associated with an increased risk for persistent pulmonary hypertension of the newborn. According to our findings, sertraline ranked as most likely to have the lowest risk for persistent pulmonary hypertension of the newborn compared to other selective serotonin reuptake inhibitors, suggesting it may have the best safety profile for use in pregnancy in this regard. Further studies are needed to fully establish these results.

INTRODUCTION: Several fluoroquinolone antibiotics have been associated with cardiac adverse effects, leading to the withdrawal of some of these agents from the market. Cardiac side effects such as QT prolongation and torsades de pointes (TdP) have also been observed with fluoroquinolones currently on the market. In order to evaluate the cardiac risk of fluoroquinolones as a class, and the comparative risk for each individual drug, we conducted a systematic review, meta-analysis, and network meta-analysis. METHODS: MEDLINE, EMBASE and the Cochrane Library were searched, up to March 2018, for randomized controlled trials, cohort studies, and case-control studies that investigated the association between fluoroquinolone treatment and the risk of cardiovascular events and cardiovascular mortality. We followed the PRISMA 2009 guidelines for data selection and extraction. Outcomes were pooled using random effects models. Direct and indirect comparisons in network meta-analysis were performed using frequentist methods. RESULTS: Thirteen studies were included in our analyses. Fluoroquinolone use was associated with a statistically significant 85% increase in the risk for arrhythmia (odds ratio [OR] 1.85; 95% confidence interval [CI] 1.22-2.81) and 71% increase in the risk for cardiovascular mortality (OR 1.71; 95% CI 1.39-2.09). Moxifloxacin ranked most likely to have the highest risk for arrhythmia (P-score 0.99) and for cardiovascular mortality (P-score 0.95) by network meta-analysis. CONCLUSIONS: Our findings show a significant association between fluoroquinolone use and an increased risk for arrhythmia and cardiovascular mortality. Moxifloxacin ranked with the highest probability for cardiovascular adverse events. Further study is required to determine how to reduce the risk for fluoroquinolone-associated cardiac toxicity.

Acetaminophen is the analgesic and antipyretic most commonly used during pregnancy. Evidence of neurodisruptive properties is accumulating. Therefore, we sought to evaluate the risk for attention deficit hyperactivity disorder (ADHD) and autistic spectrum disorder (ASD) in the offspring of women exposed to acetaminophen during pregnancy. We searched MEDLINE, Embase, and Cochrane databases for relevant studies up to January 2017. Data were independently extracted and assessed by 2 researchers. Seven eligible retrospective cohorts included 132,738 mother-child pairs, with follow-up periods ranging from 3 to 11 years. The pooled risk ratio for ADHD was 1.34 (95% confidence interval (CI): 1.21, 1.47; I2 = 72%); for ASD, the risk ratio was 1.19 (95% CI: 1.14, 1.25; I2 = 14%), and for hyperactivity symptoms, it was 1.24 (95% CI: 1.04, 1.43; I2 = 93%). In meta-regression analysis, the association between exposure and ADHD increased with the child's age upon follow-up (ß = 0.03, 95% CI: 0.00, 0.07) and with the mean duration of exposure (ß = 0.00, 95% CI: 0.00, 0.01). The available data is of observational nature only. Studies differed widely in exposure and outcome assessment. Acetaminophen use during pregnancy is associated with an increased risk for ADHD, ASD, and hyperactivity symptoms. These findings are concerning; however, results should be interpreted with caution given that the available evidence consists of observational studies and is susceptible to several potential sources of bias.

Studies reporting an increased risk for cardiac toxicities with macrolide antibiotics have raised concern regarding their cardiovascular safety. We sought to assess the cardiac safety of macrolide antibiotics as a class and of the individual agents by conducting a systematic review and network meta-analysis. Medline, Embase, and the Cochrane Library were searched up to February 2018 for studies reporting on cardiovascular outcomes with macrolides. We followed the PRISMA 2009 guidelines for data selection and extraction. Outcomes were pooled using random-effects models and odds ratios (OR), and 95% confidence intervals (CI) were calculated for arrhythmia, cardiovascular death, and myocardial infarction (MI). A total of 33 studies and data on 22,601,032 subjects were retrieved and included in the current meta-analyses. Macrolide use was not associated with the risk of arrhythmia or cardiovascular mortality. In the primary analysis, macrolide use was associated with a small but statistically significant 15% increase in risk for MI (OR = 1.15 [95% CI, 1.01 to 1.30]). In indirect network meta-analysis, erythromycin and clarithromycin were ranked considerably more likely to be associated with a higher risk for MI and significantly associated with increased risk of MI compared to azithromycin (OR = 1.58 [95% CI, 1.18 to 2.11] and OR = 1.41 [95% CI, 1.11 to 1.81], respectively). Our findings indicate that macrolide antibiotics as a group are associated with a significant risk for MI but not for arrhythmia and cardiovascular mortality. Among the macrolides, erythromycin and clarithromycin were associated with a greater risk of MI. However, it is possible that the association between macrolide use and risk of MI is the result of residual confounding.

Benzathine Penicillin G (BPG) is commonly used for treatment of penicillin-susceptible infections and secondary prevention of rheumatic fever. Death following administration of BPG is extremely rare-only a handful of cases have been described in the literature since the 1950's. In this case series from Israel and Switzerland, we describe nine cases of serious adverse reactions-six fatal reactions and three near-fatalities-occurring within minutes of receiving intramuscular BPG. Allergic reactions or faulty administration were not implicated in any of the cases; however, all patients had cardiac risk factors. This case series describes a relatively rare risk that should be borne in mind when prescribing BPG.
RESUMO
BACKGROUND: Due to the limited safety data available at the time that a new medication is first marketed, it is essential to continue the collection and monitoring of safety data about adverse drug reactions (ADRs) during the medication's life cycle. This activity, known as pharmacovigilance (PV), is performed worldwide by the pharmaceutical industry as well as by regulatory agencies. In 2012, the Israeli Ministry of Health (MOH) established a Pharmacovigilance and Drug Information Department. The Department is tasked with identifying, monitoring, and initiating activities aimed at minimizing risks associated with medication utilization. To enable this, the MOH has devised procedures for PV and promoted extensive legislation in this area that require marketing authorization holders (MAHs) and medical institutions in Israel to report ADRs and new safety information to the MOH. A computerized database was created to support the reporting process. The objective of this article is to characterize the PV tools and activities implemented in Israel. METHODS: Since September 2014, The Israeli Pharmacovigilance and Drug Information Department receives ICSRs at a central computerized database developed for this purpose. The data were analyzed by Department personnel and ICSRs were characterized according to their seriousness, source, categories of drugs involved, and the reporting format. Additionally, the Department reviewed signals detected from ADR reports and from other sources and assessed the resulting regulatory actions. RESULTS: An analysis of the Individual Case Safety Reports (ICSRs) submitted to the MOH's ADRs central database reveals that during the review period, a total of 16,409 ICSRs were received by the Department and 850 signals were identified, resulting in the following PV activities: inquiry and enhanced follow-up (430, 50.6%), prescriber's and patient's leaflets updates (204, 24%), recall of products/batches (6, 0.7%), alerts for health care professionals (63, 7.4%). Eighty five (10%) of the signals required a comprehensive investigation involving external specialist and 1 (0.1%) resulted in initiation of epidemiologic study. Additionally, in 2015 the Department incorporated comprehensive framework for risk minimization of marketed medicinal products, also known as risk management plans (RMPs). CONCLUSIONS: As practiced by other health authorities, the Israeli MOH effectively implemented various PV tools to ensure the safety of the Israeli health consumer.
