Background: Sodium-glucose cotransporter-2 inhibitors (SGLT-2i) have recently been linked to be associated with acute pancreatitis (AP), but the clinical characteristics are unclear. This study investigated the clinical characteristics of SGLT-2i and AP and provided reference for the prevention and treatment of AP.

Research design and methods: Case reports, case series, and clinical studies of SGLT2i induced AP were collected by retrieving Chinese and English data from the database until 31 December 2023.

Results: Twenty-one patients were included, with a median age of 50.5 years (range 26,73). SGLT-2i were mainly involved in empagliflozin (13 cases, 61.9%), canagliflozin (4 cases, 19%) and dapagliflozin (4 cases, 19%). The median time from initial administration to the onset of AP was 21 days (range 1, 120). Abdominal pain (21 cases, 100%) was the most commonly complained symptom. The median lipase value was 388 U/L (range 36, 10000), and the median amylase value was 535 U/L (range 26, 3765). Twenty-one patients recovered completely after stopping the drug and receiving conservative treatment.

Conclusions: SGLT-2i are associated with AP. Given the rising prescription of SGLT-2i, physicians should consider these agents as a potential cause of pancreatitis after excluding other etiologies.

Background: As synthesis technology advances, novel and efficient derivatives of tetracyclines are found. Three new antibiotics were approved within the past 18 years, and represent a new era in the use of tetracyclines. To gain further insight into adverse events linked to tetracyclines and better protect pediatric patients, ongoing monitoring of safety data is crucial.

Methods: The FAERS data from the first quarter of 2004 to the third quarter of 2023 in the AERSMine were extracted to conduct disproportionality analysis. The association between five tetracyclines and adverse events was evaluated using reporting odds ratio, and their risk factors were explored by multivariate logistic regression analysis.

Results: Our study showed that thyroid gland disorders had the strongest signal in children. Patients aged 12-18 and treatment with minocycline are risk factors for thyroid adverse events (12-18: OR = 10.727 [7.113-16.177], p < 0.0001; minocycline: OR = 17.025 [10.475-27.678], p < 0.0001). Second-generation tetracycline and third-generation tetracycline ADR patterns differed. Blood fibrinogen decreased and hypofibrinogenaemia was primarily reported with tigecycline and eravacycline.

Conclusion: This study provided basic evidence for further research on tetracyclines-related adverse events. However, the safety of third-generation tetracycline in children requires additional validation through a large-scale prospective study.

Background: Intravesical therapy is a commonly utilized treatment for non-muscle invasive bladder cancer (NMIBC). This study focuses on summarizing the signals of all intravesical drugs and aims to highlight the comprehensive differences in adverse events (AEs) between these drugs.

Research design and methods: We conducted pharmacovigilance data analysis based on the real-world big data from the Food and Drug Administration Adverse Event Reporting System (FAERS) database.

Results: We elucidated all signals compared with the overall FAERS database or other administration routes for Bacillus Calmette-Guerin (BCG), mitomycin, gemcitabine, valrubicin, and epirubicin. Notably, the distribution of reported AEs associated with intravesical therapy exhibited a noticeable inclination toward male patients. Furthermore, all five drugs demonstrated a disproportionate distribution in local AEs, particularly in renal and urinary disorders. Additionally, specific signals and findings were summarized for each individual drug. Finally, we highlighted the AEs that resulted in serious outcomes for each drug.

Conclusion: We have compiled an overview of the AEs tied to intravesical drugs whilst considering their individual distinctions. These insightful findings serve to enrich our comprehension of the safety profiles and potential risks linked to intravesical therapy.

Introduction: The rising prevalence of psychiatric disorders has resulted in a significant increase in the use of antipsychotic medications. These agents may prolong the corrected QT interval (QTc), running the risk of precipitating ventricular arrhythmias, notably Torsades de Pointes (TdP). Current recommendations vary regarding the optimal approach to safe prescribing practices and QTc surveillance for antipsychotics. This review summarizes the current literature addressing these clinical concerns.

Areas covered: The physiologic basis of the QTc interval, mechanisms underlying its susceptibility to pharmacological influence, specific risks associated with atypical antipsychotic agents, and recommendations for safe prescription practices. We performed a literature review using Pubmed and Embase databases, searching for 'antipsychotics' and 'torsades de pointes.'

Expert opinion: Finding a safe and universally accepted protocol for prescribing antipsychotics remains a persistent challenge in medicine. Predictive models that integrate clinical history with demographic and ECG characteristics can help estimate an individual's susceptibility to therapy-associated risks, including QTc prolongation. Agents such as ziprasidone and iloperidone are significantly more likely to prolong the QTc interval compared to others such as brexpiprazole, cariprazine, olanzapine, and clozapine. A personalized approach using low-risk medications when clinically feasible, and at the lowest efficacious dose, offers a promising path toward safer antipsychotic prescribing.

Background: The aim of this study was to evaluate the association between CDK4/6 inhibitors and QT interval prolongation (QTp) and Torsades de Pointes (TdP) in breast cancer patients.

Method: The cases with breast cancer from 2015 to 2022 were extracted from the FDA adverse event database (FARES) and further divided into a CDK4/6 inhibitor group and a positive control group. The associations between CDK4/6 inhibitors and QTp and TdP adverse events were evaluated using the reporting odds ratio (ROR) and the information component (IC).

Results: A total of 172,266 breast cancer patients were included. A total of 234 QTp/TdP events occurred in the CDK4/6 inhibitor group. Disproportionality analysis revealed that ribociclib was related to QTp/TdP. The ROR was 10.10 (95% 8.56-11.92), and the IC was 2.84 (95% 2.28-3.32). Palbociclib and abemaciclib had no correlation with QTP/TDP events.

Conclusion: Based on this real-world pharmacovigilance analysis, this study demonstrated a significant association between ribociclib and QTp/TdP events, which should attract clinical attention. The QT interval was monitored before and after medication. Attention should be given to adjusting the drugson time.

Introduction: Age-related macular degeneration (AMD) is a progressive retinal degenerative disease that is implicated as one of the leading causes of visual impairment in the elderly population. Vascular endothelial growth factor (VEGF) has been identified as the main driver of AMD, and various therapeutics have revolutionized the treatment and management of neovascular AMD (nAMD) with favorable visual and anatomical outcomes.

Areas covered: Physicians have a variety of approved therapeutics in their arsenal for patients with varying disease progression and patient-specific needs, with the ultimate goal of achieving optimal visual and anatomic outcomes. The literature search was conducted using PubMed, Google Scholar, and sources from companies' websites, allowing us to locate findings recently presented at conferences.

Expert opinion: Scientific advancements in the field have led to newly approved therapeutics and devices, such as the port-delivery system with ranibizumab (PDS), and further investigation is ongoing in the realm of gene therapy for retinal diseases. In addition to efficacy and durability, newer agents must have comparable safety profiles to older agents in order to be used broadly. These options introduce a level of complexity in nAMD treatment; however, physicians to personalize treatment to improve vision in nAMD patients and reduce treatment burden overall.

Introduction: Many of the first line medications for the treatment of active and latent M. tuberculosis are hepatoxic and cause a spectrum of anti-tuberculosis drug induced liver injury (ATLI), including acute liver failure (ALF). Despite advances in recognition of and prevention of ATLI, isoniazid remains one of the leading causes of DILI as well as drug-induced ALF.

Areas covered: A literature search of the incidence, risk factors, current societal guidelines, monitoring, and prophylactic medication usage in ATLI was performed using PubMed and institutional websites. Relevant articles from 1972 to 2024 were included in this review.

Expert opinion: Current societal guidelines regarding ATLI monitoring are mixed, but many recommend liver enzyme testing of high-risk populations. We recommend liver test monitoring for all patients on multi-drug therapy as well as those on isoniazid therapy. Precision medicine practices, such as N-acetyltransferase-2 polymorphism genotyping, are thought to be beneficial in reducing the incidence of ATLI in high-risk populations. However, broader implementation is currently cost prohibitive. Hepatoprotective drugs are not currently recommended, although we do recognize their potential. In patients who develop ATLI but require ongoing anti-TB treatment, strategies to restart the same or less hepatotoxic regimens are currently being followed.

Objectives: Through the use of FDA adverse event reporting system (FAERS) dataset, this study analyzes the pattern of time-to-event (TTE) for drugs and adverse events, and suggest ways to identify candidate late-onset events for monitoring.

Methods: The duration between administration date of the drug and the onset of adverse events was explored with using FAERS data from 2012-2021. The fold change of proportional reporting ratios or reporting odds ratios were calculated to identify enriched events in the later period and to suggest the late-onset events for further monitoring. To compare the findings, we used the claims database of the Korean National Health Insurance Service (NHIS).

Results: A total of 1,426,781 reports were included. The median TTE was 10 days (interquartile range [IQR]: 0-98 days), with 11.5% (n = 164,093) reporting events that occurred at least one year after administration. TTE and fold change analysis captured historical cases of late-onset events, while generating an additional less-explored list of events. The results for tumor necrosis factor (TNF) inhibitors were compared using the NHIS dataset.

Conclusion: Our study provides a comprehensive analysis of the FAERS dataset, focusing on TTE data. Periodic summarization of reports would be helpful in monitoring the late-onset events.

Introduction: Antipsychotic (AP) medications are extensively utilized for diverse psychiatric and non-psychiatric conditions, but they are associated with significant adverse effects in older adults. This expert opinion review provides an updated profile of adverse effects associated with AP medications in older adults.

Areas covered: This review specifically examines real-world evidence for adverse events associated with AP use, including all-cause mortality, falls and fractures, diabetes, cardiovascular and cerebrovascular events, acute kidney injury, venous thromboembolism/pulmonary embolism, extrapyramidal symptoms, and infections based on real-world evidence.

Expert opinion: This comprehensive safety review of AP revealed multiple adverse events in older adults. All-cause mortality, more associated with typical APs than atypicals, underscores a dose-dependent risk, urging cautious prescribing practices and avoidance of typical APs. Falls/fractures associated with atypical APs highlight the importance of judicious dosing and -close monitoring, especially after initiation. Cardiovascular risks, particularly stroke, with AP use emphasize the need for vigilant monitoring. Extrapyramidal symptoms, more linked to typical APs, also pose a significant risk in older adults. Pneumonia and pulmonary embolism/venous thromboembolism demand cautious consideration of APs, prompting the need for additional real-world studies to inform clinical practice. Conflicting evidence on diabetes and acute kidney injury necessitates ongoing studies and further research in older adults.
