Objective: This study evaluates the risk of ocular adverse events (AEs) associated with glucagon-like peptide-1 receptor agonists (GLP-1 RAs) using data from the FDA Adverse Event Reporting System (FAERS) and network pharmacology methods.

Methods: FAERS data from 2004 to 2024 were analyzed for ocular AEs linked to GLP-1 RA treatments. Disproportionality analysis (Reporting Odds Ratio, ROR) was used to identify signals, and a drug-gene interaction network explored potential mechanisms.

Results: Among 17,785,793 FAERS reports, semaglutide and lixisenatide were significantly associated with ocular AEs, with RORs of 1.25 (95% CI, 1.20-1.31) and 1.96 (95% CI, 1.70-2.27), respectively. Commonly reported AEs included blurred vision, visual impairment, and diabetic retinopathy, with some AEs occurring as early as 10 days after treatment initiation. Gene enrichment analysis highlighted potential links between GLP-1-related genes and ocular AEs.

Conclusion: The widespread use of GLP-1 RAs has raised concerns regarding their ophthalmic safety. This study contributes new evidence from real-world data, suggesting that semaglutide and lixisenatide are associated with significant risks of ocular AEs. Further experimental studies are warranted to elucidate the underlying mechanisms and confirm these associations.

Introduction: Metformin has been part of treatment algorithms for type 2 diabetes mellitus (T2DM) for decades. While it has formal approval in the U.S.A. for treatment of T2DM, it is used off-label in gestational diabetes mellitus (GDM), polycystic ovarian syndrome (PCOS), and ovarian hyperstimulation prevention. Its role as an insulin sensitizer has made it an attractive therapeutic to address the insulin resistance seen in these syndromes. In 2022, the European Union approved metformin as the only oral antidiabetic medication for diabetes in pregnancy. While its safety and benefits for the mother are well documented, it does cross the placenta with plasma concentrations comparable between mother and child at delivery.

Areas covered: This special report will focus on major randomized control trials investigating metformin use in pregnancies impacted by PCOS, GDM, T2DM, and obesity and their offspring follow-up trials.

Expert opinion: For the mother, metformin can be beneficial, with reduction in insulin therapeutic burden, weight gain, hypoglycemia and in certain situations, pre-eclampsia. For the neonate, benefits may include reduction in hypoglycemia and no increased risk of congenital anomalies. It is the long-term data in the offspring that remains unknown with some areas of concerns (SGA, altered anthropometrics) requiring continued research.

Introduction: Statins are well established as the first-line treatment to reduce low-density-lipoprotein cholesterol (LDL-C) and cardiovascular (CV) events, but some patients are unable to tolerate effective doses or sometimes any dose of statins and alternative treatments may be required.

Areas covered: In this review we summarize the relevant published literature obtained from a PubMed search on the safety of statin alternatives for the treatment of hypercholesterolemia.

Expert opinion: The main alternatives to statins are ezetimibe, the proprotein convertase subtilisin/kexin type 9 (PCSK9) inhibitors, evolocumab, alirocumab, and inclisiran, and the recently approved bempedoic acid. These have all shown an excellent safety profile and have not been associated with skeletal muscle symptoms or with increased risk of new onset diabetes and they have no major drug interactions. The injectable PCSK9 inhibitors are associated with a small increase in injection site reactions which are usually of mild or moderate intensity. Bempedoic acid is associated with a small increase in plasma uric acid and slightly increased frequency of episodes of gout in susceptible subjects. The cost and availability and the degree of lowering of LDL-C required are more likely to determine the choice of statin alternatives than the safety issues.

Background: This investigation aims to identify and evaluate the most common and critical drugs associated with the risk of noninfectious myocarditis utilizing the US Food and Drug Administration Adverse Event Reporting System (FAERS) database.

Methods: Data pertaining to noninfectious myocarditis from 2004 Q1 to 2024 Q2 were extracted. Following data standardization, multiple signal quantification techniques, including Reporting Odds Ratio (ROR) and Proportional Reporting Ratio, were employed for analysis.

Results: The study identified a total of 10,763 adverse event reports associated with noninfectious myocarditis. Disproportionality analysis revealed that the top 5 drugs by ROR were phendimetrazine tartrate (ROR 104.64), trimethoprim + sulfamethoxazole (ROR 67.65), aldesleukin (ROR 52.67), mesalazine (ROR 49.73), and balsalazide disodium (ROR 45.26). Notably, among the 30 drugs with the strongest ROR signals, 8 drugs lacked myocarditis risk information in their package inserts.

Conclusion: Through comprehensive analysis of the FAERS database, our study identified drugs with a strong signal for myocarditis that are not currently indicated on their labels. The findings suggest that the potential risk of myocarditis associated with these medications is significant and warrants close monitoring in clinical practice.

Introduction: Acute myeloid leukemia (AML) is typically characterized by a poor prognosis, mainly due to the median age at diagnosis. Until recently, treatment options were limited to intensive chemotherapy (IC) for young patients or hypomethylating agents for those ineligible for IC. Since 2017, nine molecules were registered for newly-diagnosed AML: midostaurin, gilteritinib, quizartinib, enasidenib, ivosidenib, gemtuzumab ozogamicin, CPX-351, glasdegib, and venetoclax.

Areas covered: The review examines the safety profile of these drugs and their interactions with other agents used in supportive care. The PubMed and Google Scholar databases were searched for articles in English concerning new agents in AML from 2017 until 2023. Further relevant publications were obtained by reviewing the prescribing information and Food and Drug Administration (FDA) data.

Expert opinion: The therapeutic spectrum in AML has broadened over several years and can also improve outcomes in older patients. However, in addition to their well-known cytotoxic activity, new molecules cause several unique, off-target toxicities. Also, potential drug-drug interactions (DDI) should be taken into consideration when choosing optimal first-line therapy; this remains a challenge in clinical practice.

Introduction: Proton pump inhibitors (PPIs) rank among the most frequently prescribed medications to treat acid-related diseases. Mounting concerns surround the potential for serious adverse events, including cardiovascular events, associated with their prolonged use/misuse.

Areas covered: This comprehensive review explores cardiovascular adverse events linked to PPI use among high-risk cardiovascular patients. A structured search was conducted on PubMed.

Expert opinion: Many patients with cardiovascular disease who require antiplatelet treatment will require long-term PPI treatment. Interpreting the published data is not straightforward. First, because there is no plausible mechanistic explanation for PPIs to induce cardiovascular events apart from the potential interaction with the metabolism of thienopyridines. Although several observational studies have shown an increased cardiovascular risk and mortality in patients taking long-term PPIs, most available clinical trials and meta-analyses of available studies do not. However, the absence of firm evidence of this link does not necessarily imply that this association does not exist, and other hypothesis must be explored. Anemia is a common event in patients who take antiplatelet therapy and PPIs, and it is a factor associated with cardiovascular events and death. Anemia in these patients is often attributed to erosive lesions of the small intestine, where PPI may play a key role by modifying the microbiota.

Background: Limited understanding exists regarding the hemorrhagic risk resulting from potential interactions between P-glycoprotein (P-gp) inhibitors and direct oral anticoagulants (DOACs). Utilizing the Food and Drug Administration Adverse Event Reporting System (FAERS) data, we analyzed hemorrhagic adverse events (AEs) linked with the co-administration of P-gp inhibitors and DOACs, aiming to offer guidance for their safe and rational use.

Methods: Hemorrhagic events associated with P-gp inhibitors in combination with DOACs were scrutinized from the FAERS database. Hemorrhagic signals mining was performed by estimating the reported odds ratios (RORs), corroborated by additive and multiplicative models and a combination risk ratio (PRR) model.

Results: Our analysis covered 4,417,195 cases, revealing 11,967 bleeding events associated with P-gp inhibitors. We observed a significantly higher risk of bleeding with the combination of apixaban and felodipine (ROR 118.84, 95% CI 78.12-180.79, additive model 0.545, multiplicative model 1.253, PRR 22.896 (2450.141)). Moreover, consistent associations were found in the co-administration analyzes of rivaroxaban with dronedarone and diltiazem, and apixaban with losartan, telmisartan, and simvastatin.

Conclusion: Our FAERS data analysis unveils varying degrees of bleeding risk associated with the co-administration of P-gp inhibitors and DOACs, underscoring the importance of vigilance about them in clinical practice.

Background: Current clinical trial data on PARP inhibitors (PARPis)-related acute renal failure (ARF) are not entirely representative of real-world situations. Therefore, in this study, the US Food and Drug Administration Adverse Event Reporting System (FAERS) was used to evaluate PARPis-related ARF.

Research design and methods: Data were obtained from 1 January 2015, to 30 September 2023. ARF event reports were analyzed based on four algorithms. The time-to-onset (TTO) and clinical outcomes of PARPis-associated ARF were assessed.

Results: The total included cases were 2726. Significant signals were observed for olaparib, niraparib, and rucaparib (reporting odds ratio (ROR): 1.62, 95% confidence interval (CI): 1.49-1.78, 1.25, 95% CI: 1.19-1.32 and 1.59, 95% CI: 1.47-1.72 respectively). The median TTO of ARF onset was 57, 36, and 85 days for olaparib, niraparib, and rucaparib, respectively. The proportion of deaths with olaparib (9.88%) was significantly higher than for niraparib (2.52%) and rucaparib (2.94%) (p < 0.005). The proportion of life-threatening adverse events associated with niraparib (4.89%) was significantly higher than for rucaparib (0.98%) (p < 0.005).

Conclusions: ARF and PARPi were related, with the exception of talazoparib. More emphasis should be given to PARPis-related ARF due to the high proportion of serious AEs and delayed adverse reactions.
