Introduction: Eplerenone is approved for the treatment of hypertension as well as symptomatic heart failure with reduced ejection fraction (HFrEF) following an acute myocardial infarction. However, the adverse events (AEs) have not been systematically analyzed. The aim of this study was to identify adverse drug reactions (ADRs) related to eplerenone using the FDA Adverse Event Reporting System (FAERS) database. By identifying previously unreported AEs, the study could potentially contribute to updating the drug’s label.
Methods: In order to find significant AEs, four algorithms, including Reporting Odds Ratio (ROR), Proportional Reporting Ratio (PRR), Bayesian Confidence Propagation Neural Network (BCPNN) and Empirical Bayesian Geometric Mean (EBGM), were used to analyze the signal strength of the ADRs connected to eplerenone that were gathered from the FAERS database over the previous 20 years.
Results: From 2004Q1 to 2023Q4, a total of 20, 629, 811 reported cases were gathered from the FAERS database for this study. After processing the data and filtering, 1,874 case reports were analyzed. Of these cases, 1,070 AEs were identified, 128 of which were eplerenone-related ADRs. We investigated the occurrence of ADRs induced by eplerenone in 27 organ systems. Our study showed that the AEs listed in the medication’s package insert correspond with those listed in the literature, including hyperkalemia and increased creatinine. Additionally, the prescription label for eplerenone does not include all system organ class (SOC) terms, like Vascular disorders, hepatobiliary Disorders, etc.
Discussion: The study used multiple algorithms to quantify the signal strength and then identified any previously unrecognized ADRs, further studies are needed to confirm the association of ADRs with eplerenone. The findings of this study may provide important insights into the safety profile of eplerenone, ensure that healthcare providers have up-to-date information about their potential risks and help guide them in the correct use of the drug.
1 Introduction
Eplerenone, an aldosterone antagonist, is used to increase survival in stable patients with symptomatic heart failure with reduced ejection fraction (HFrEF) following an acute myocardial infarction (FDA approved in 2002). Additionally, eplerenone has been shown to effectively reduce blood pressure and minimize the risk of both fatal and nonfatal cardiovascular events, particularly myocardial infarction and stroke. Dysregulated aldosterone activity can cause adverse effects on the cardiovascular system. By blocking the effects of aldosterone, it is possible to prevent some of these adverse cardiovascular effects and improve overall cardiovascular health (Sueta et al., 2020). At present, there are two aldosterone antagonists that are widely used in clinical practice: spironolactone and eplerenone (Buffolo et al., 2022). Spironolactone and aldosterone compete for binding to the mineralocorticoid receptor, which causes sodium and fluid retention (Rist et al., 2023). The mechanism of action for eplerenone is comparable (Tam et al., 2017; Agarwal et al., 2021). Compared to aldosterone, eplerenone has a shorter half-life, and it can be metabolized into highly inactive metabolites that are easier to flush out of the body. In clinical practice, the sexual side effect of spironolactone is the primary reason why hypertensive patients often struggle with medication adherence, but the use of eplerenone can significantly reduce the incidence of such adverse events (AEs) (Burgess, 2004; Struthers et al., 2008; Kolkhof and Bärfacker, 2017). In earlier clinical studies and randomized controlled trial, the most frequently reported ADRs of eplerenone for HFrEF were hyperkalaemia and blood creatinine increased, which were also listed in the prescribing information for eplerenone (Pitt et al., 2008; Provenzano et al., 2022). Fortunately, most AEs have not yet resulted in serious adverse consequences. However, due to the limited sample size and follow-up time, a large number of AEs are still not clearly reported on the label. Thus, a more extensive analysis of the safety of eplerenone is required (Dhillon, 2013; Ferreira et al., 2019).
The FDA uses the FDA Adverse Event Reporting System (FAERS) database to track AEs, medication errors and product quality complaints reported primarily by pharmaceutical companies. Using the data that drug companies provide to the FDA, it keeps tabs on the safety of pharmaceuticals and therapeutic biologics that are available on the market. The FAERS database compiles data that is provided by pharmaceutical companies, with the aim of monitoring the safety of drugs and therapeutic biologics on the market. It serves to identify potential safety signals and uncover latent safety concerns, thereby enhancing regulatory oversight and improving the safety of medications (Anand et al., 2019; Zhou and Hultgren, 2020). Recent research has shown that using the FAERS database to analyze medications can uncover a variety of potential negative effects associated with drugs. For example, poly (ADP-ribose) polymerase inhibitors (PARPis) are known as targeted drugs for cancer therapy, and many types of PARPis are widely used in clinical practice, but the differences between these PARPis have not been clarified in the real world. Using the information in the FAERS database, the differences in ADRs associated with different PARPis can be identified to improve the safety of the drug during treatment (Tian et al., 2022). Besides, quetiapine is an antipsychotic medication that has been approved for the treatment of various psychiatric diseases. Due to the limitations of clinical trials, we were unable to investigate the potential link between quetiapine and rare adverse cardiac events, but analysis using the FAERS database could offer valuable evidence for reducing the risk of quetiapine-related adverse cardiac events (Shu et al., 2023). Although the information in the FAERS database does not prove a direct causal relationship between the drug and AEs, it serves as a valuable resource for analyzing and monitoring drug safety.
In this study, four strict algorithms were used to screen eplerenone-related ADRs based on the FAERS database, comprehensively analyze the AEs in different systems, and explore the gender-based differences in AEs. Our study aims to identify and categorize additional AEs that aren’t listed on the label and provide recommendations for the safe clinical usage of eplerenone.
2 Materials and methods
2.1 Data source and collection
The FAERS database is the largest database in the world for reporting instances involving harmful drugs. It performs safety monitoring of therapeutic biological products and pharmaceuticals that have been put on the market by gathering safety information on them. Drug manufacturers are required to submit any collected reports to the FDA (https://www.fda.gov/drugs/questions-and-answers-fdas-adverse-event-reporting-system-faers/fda-adverse-event-reporting-system-faers-public-dashboard) (Omar et al., 2021; Zhang et al., 2022).
In order to improve accuracy, only eplerenone as PS drugs were retained in this study. In our study, we extracted eplerenone-related ADRs reported from 2004Q1 to 2023Q4 from the FAERS database. The data were captured and pre-processed using SAS and Navcat for MySQL software, and following straightforward processing, they were mapped to the MedDRA concept to eliminate duplicate case records and find AEs using statistical techniques, and then we computed significant AEs and mapped them to preferred terms (PTs) and system organ class (SOC) that correspond to various MedDRA levels (Figure 1). The study used the FAERS database to identify ADRs using eplerenone as the main suspected drug type. This study examined five factors: gender, weight, age, reported countries, and report source, with additional consideration of gender-based differences in ADRs.
2.2 Statistical analysis
The statistical analysis employed descriptive statistical methods to ADRs associated with eplerenone. To find pairs of ADRs associated with eplerenone, we employed several algorithms for metrics. We used four algorithms, including Reporting Odds Ratio (ROR) (Rothman et al., 2004), Proportional Reporting Ratio (PRR) (Evans et al., 2001), Bayesian Confidence Propagation Neural Network (BCPNN) (Ang et al., 2016) and Empirical Bayesian Geometric Mean (EBGM) (Rivkees and Szarfman, 2010) to calculate all AEs to find significant ADRs. Before computing the ROR and PRR, we initially obtained the four values of a, b, c and d (where a indicates total number of people who had the specified AEs after exposure to eplerenone, b indicates total number of people with non-target AEs after being exposed to eplerenone, c indicates total number of people with target AEs after exposure to non-eplerenone, d indicates total number of people who developed non-targeted AEs after being exposed to non-eplerenone (Table 1). These formulas are as follows:
2.2.1 ROR algorithm
If the lower limit of 95% CI > 1 and a ≥ 3, the ROR is a striking signal.
2.2.2 PRR algorithm
If PRR
2.2.3 BPCNN algorithm
If IC-2SD > 0 (IC-2SD: the lower bound of 95% CI), the BPCNN is a positive signal. The signal intensity was strikingly correlated with the IC-2SD value.
2.2.4 EBGM algorithm
If EBGM05 > 2 (EBGM05: the lower bound of 95% CI), the BPCNN is a striking signal.
We employed these four methods to find signals from the FAERS database from the first quarter of 2004 to the four quarter of 2023. The valid AE outcomes must concurrently satisfy the striking signal selection requirements in all four of the aforementioned methods. The data processing and statistical analysis in this study were conducted using SAS, MySQL, WPS EXCEL, and R software.
2.3 Gender-based differences of ADRs
In order to analyze the effect of gender on ADRs, we compared the ADRs of males and females after medication. Additionally, in order to evaluate the gender-specific risk of drug-related ADRs, ROR was utilized to determine the disproportional signals between males and females after eplerenone administration. If the ROR is greater than 1, it indicates that females have a higher risk for the ADR, to the contrary, if the ROR is less than 1, it indicates that males are at higher risk for the ADR.
3 Results
3.1 Descriptive results
From 2004Q1 to 2023Q4, a total of 20,629,811 reported cases were gathered from the FAERS database for this study. After being purged of duplicates and identified using four different techniques, 1,874 case reports were analyzed. Of these cases, 1,070 AEs were identified, 128 of which were eplerenone-related ADRs. Table 2 demonstrated the clinical features of eplerenone treatment events.

Table 2. The characters of case reports associated with eplerenone as primary suspected drug in FAERS (from 2004 Q1 to 2023 Q4).
Among the selected case reports, there were 1,603 cases with specific gender information, 1,136 of these cases (60.6%) were male and 467 of them (24.9%) were female. Among the 615 case reports with clear weight information, patients weighing between 50 and 100 kg (25.8%) had a higher risk of AEs. However, due to the absence of specific weight information in the FAERS database, more studies are needed to confirm this result. The case reports mainly submitted by Physician (n = 747, 39.90%), Pharmacist (n = 380, 20.30%), Consumer (n = 340, 18.10%), Other health-professional (n = 244, 13.00%) and Health Professional (n = 104, 5.50%).
3.2 Signal detects at system organ class level
Supplementary Table S1 demonstrated the ADRs signal intensity of eplerenone at the SOC level. We discovered that eplerenone-related ADRs were observed in 27 systems, which suggested that eplerenone-related ADRs were relatively common. The top five SOCs were general disorders and administration site conditions (n = 747), investigations (n = 687), cardiac disorders (n = 485), renal and urinary disorders (n = 439), metabolism and nutrition disorders (n = 437). The SOCs that met at least one of the four algprithms included investigations (n = 747), renal and urinary disorders (n = 687), metabolism and nutrition disorders (n = 485), cardiac disorders (n = 439), reproductive system and breast disorders (n = 437), hepatobiliary disorders (n = 69), vascular disorders (n = 233), endocrine disorders (n = 33), ear and labyrinth disorders (n = 36) (Supplementary Table S2). There were three SOCs that met the four algorithms at the same time, namely: renal and urinary disorders (n = 439), metabolism and nutrition disorders (n = 437), cardiac disorders (n = 485), the side effects of these three systems could also be reflected in eplerenone’s drug label (Table 3).

3.3 Signal detections ranked by the EBGM at prefer terms level
During the study, four algorithms were employed to examine adverse medication reactions and assess whether they met the filtering criteria of the four algorithms. As illustrated in Table 4, the top 30 signals simultaneously recognized by the four algorithms in order of case numbers are presented, and all the results are shown in Supplementary Table S3. At the PTs level, there were 128 ADR terms related to 18 SOCs. The most rigorous algorithm, EBGM, was used to sort the 128 selected ADRs. The top five ADRs were: venous pressure jugular decreased (n = 3), hyperaldosteronism (n = 6), giardiasis (n = 4), hyperadrenocorticism (n = 4), N-Terminal prohormone brain natriuretic peptide increased (n = 11).

Table 4. The top 30 signal strength of ADRs of eplerenone at the PTs level recognized by the four algorithms simultaneously in FAERS, and ranked by case numbers.
Among them, PT entries with more than 100 cases included acute kidney injury (n = 230), hyperkalaemia (n = 146), the second of which was consistent with the drug instructions published by FDA. Interestingly, we also found some AEs not mentioned in the instructions, which can have an effect on the respiratory system, including pulmonary oedema (n = 19), rales (n = 10); it can effect on the reproductive system and breast, including: gynaecomastia (n = 24), erectile dysfunction (n = 13); breast pain (n = 11); it may also affect the hepatobiliary system, including hepatic function abnormal (n = 11), alanine aminotransferase increased (n = 19), gamma-glutamyltransferase increased (n = 10). We also unexpectedly found that it may lead to rales (n = 18), ascites (n = 11) and gout (n = 11). In addition, using the EBGM, ROR, PRR and BCPNN screening algorithms alone, we were able to obtain 129, 183, 214, and 446 ADRs associated with eplerenone, respectively. These results are presented in Supplementary Tables S3–S6.
3.4 Gender-based differences of ADRs
To analyzed the gender-based differences in eplerenone-related ADRs, we used four algorithms to screen for drug-related ADRs in males and females. In males, we identified 101 drug-related ADRs (Supplementary Table S7), and in females, we identified 50 drug-related ADRs (Supplementary Table S8). Comparing the ADRs of different genders, we can find that 23 ADRs can be observed in both male and female, such as: hyperkalaemia, glomerular filtration rate decreased, acute kidney injury, etc. However, some ADRs can only be observed in certain genders. ADRs such as pemphigoid [n = 5, EBGM: 8.67 (4.16)], cutaneous vasculitis [n = 3, EBGM: 9.39 (3.64)], papule [n = 3, EBGM: 7.45 (2.89)], ear discomfort [n = 3, EBGM: 7.2 (2.79)], vertigo [n = 15, EBGM: 5.41 (3.54)], gout [n = 8, EBGM: 4.53 (2.53)] were only observed in males. ADRs such as haemorrhage subcutaneous [n = 3, EBGM: 39.65 (15.35)], hematochezia [n = 5, EBGM: 4.58 (2.2)], altered state of consciousness [n = 4, EBGM: 10.08 (4.43)] were only observed in females.
At the same time, ROR was used to assess the risk of gender-specific ADRs, and we found that ADRs such as hyponatraemia and chest Pain occur equally in males and females, malaise [1.83 (1.03–3.26)], death [0.38 (0.15–0.98)], renal impairment [0.37 (0.15–0.95)], blood creatinine increased [0.22 (0.07–0.73)], glomerular filtration rate decreased [0.29 (0.09–0.97)] were more likely to occur in males, pneumonia [4.02 (1.56–10.4)], hepatic function abnormal [5.11 (1.28–20.46)], epistaxis [5.11 (1.28–20.46)], fracture [4.25 (1.02–17.83)], nervousness [6.38 (1.24–32.94)], haematochezia [4.25 (1.02–17.83)], blood uric acid increased [10.21 (1.14–91.43)] were more likely to occur in females (Table 5; Figure 2).
4 Discussion
Cardiovascular disease (CVD) is the leading cause of death in western countries and poses a serious threat to human health (Farbehi et al., 2019; Hemanthakumar et al., 2021). CVD also imposes a substantial financial burden on patients (Patel et al., 2022). The GEO database serves as a rich repository of reports on CVD, offering a valuable resource for analyzing the underlying biological processes and identifying potential genetic targets for CVD treatment (Liu et al., 2021). Eplerenone has been approved by the FDA for the treatment of HFrEF since 2002. However, eplerenone has been relatively recently introduced into clinical practice, and it can be challenging to fully comprehend all the potential ADRs of eplerenone solely through clinical trials. Pre-marketing trials cannot generalize about all potential AEs in the real world. Therefore, it is necessary to continue to monitor the safety of drugs after marketing (Patel et al., 2022). In recent years, data mining using large databases as an exploratory research method for the prevention of ADRs has attracted people’s attention. FAERS database plays a significant function in the absence of clinical trials, especially when monitoring the long-term effects of drug therapies for chronic diseases like CVD becomes essential. The FAERS database gathers a variety of data on AEs and side effects associated with the usage of medicinal products, which is mostly submitted by drug manufacturers, with some data voluntarily submitted by drug users and other healthcare professionals (Yu et al., 2021; Yang et al., 2023). By accessing publicly available FAERS data, we can identify ADRs associated with eplerenone, monitor the drug’s safety, and provide guidance for its usage. In this study, we concentrated on AEs recorded in the FAERS database specifically for eplerenone, with the aim of identifying ADRs that were not recorded in the drug insert.
Significant SOCs identified by the four algorithms included cardiac disorders (n = 485), renal and urinary disorders (n = 439), metabolism and nutrition disorders (n = 437), which had been reported in clinical trials or shown in the drug label. ADRs mentioned in the FDA’s drug label include hyperkalemia, increased creatinine and hypertension. This was also confirmed in our study, which also illustrated the reliability of our results.
Four algorithms were used for analysis and screening. After excluding PT as the primary suspect (PS) for eplerenone therapy or complications, we concerned about some ADRs, which were not mentioned in the drug label, such as: glomerular filtration rate decreased [n = 29, EBGM: 29.44 (29.44)], creatinine renal clearance decreased [n = 11, EBGM: 27.62 (16.82)] and acute kidney injury [n = 230, EBGM: 12.88 (11.53)]. The drug label provided by the FDA noted that using eplerenone may increase creatinine levels, which indicated that eplerenone may cause impaired kidney function. Some studies have shown that treatment with eplerenone may increase the likelihood of a short-term decline in kidney function (Chung et al., 2020), however, eplerenone may also show renal protection in patients with normal or low aldosterone levels (Rafiq et al., 2011). Similar findings have been found in MRAs, which they suggest is haemodynamically mediated and reversible (at least up to > 30% change), which further indicates the potential renal benefits of eplerenone. This suggested that the effect of eplerenone on renal function may be related to baseline renal function. Therefore, renal function should be monitored in clinical applications.
Other ADRs we have noticed included giardiasis [n = 4, EBGM: 139.32 (60.97)] and escherichia sepsis [n = 3, EBGM: 11.21 (4.34)]. In one animal study, eplerenone treatment was found to promote the polarization of macrophages towards the M2-like phenotype (van der Heijden et al., 2018). However, the polarization of M1 macrophages will promote the phagocytosis of macrophages, and then kill colon bacillus (Chen et al., 2023). At the same time, the imbalance between gut microbiota and M2 macrophages can affect intestinal health and homeostasis, which may weaken the body’s protection against Giardia infection (Xaplanteri et al., 2023). Some studies have shown that eplerenone can inhibit ILC3, and then prevent the production of IL17, which has a protective effect against giardia infection (Xaplanteri et al., 2023; Zhao et al., 2024). These views were consistent with our findings. Although the number of reports of this ADR is not large, and it is not certain that this ADR is related to the use of eplerenone, we can not ignore the possible negative impact of eplerenone on the body’s immune mechanism. It is necessary to carry out further research to investigate the significance of this ADR and its association with eplerenone.
Among the screened ADRs, we also focused on gamma-glutamyltransferase increased [n = 10, EBGM: 4.67 (2.78)], alanine aminotransferase increased [n = 19, EBGM: 3.3 (2.27)] and hepatic function abnormal [n = 1q, EBGM: 3.4 (2.07)]. Although there are no reports of liver injury caused by eplerenone, a study reported in Clinical and Research Information on Drug-Induced Liver Injury suggested that eplerenone may be sensitive to acute liver injury (Eplerenone, 2012). The possible mechanism of liver injury is that the intermediates produced by the metabolism of eplerenone in the liver may cause liver reactions (Barnes and Howard, 2005). Therefore, in the course of medication, we should also pay attention to exclude potential liver injury.
In the reproductive system and breast diseases, we found that in addition to gynaecomastia, erectile dysfunction may also develop. In a study published in 2003, William F. Young Jr. reported that eplerenone is a selective aldosterone receptor blocker without the side effects associated with spironolides, including gynaecomastia, erectile dysfunction, and menstrual irregularities. However, our research showed that aldosterone receptor blockade may only partially reverse these effects, suggesting that eplerenone side effects may still exist (Lainscak et al., 2015). Therefore, these side effects should be closely concerned during the use of eplerenone, which may affect patient compliance.
According to our results, we also noticed some interesting ADRs, such as prothrombin time prolonged [n = 4, EBGM: 6.57 (2.89)] and activated partial thromboplastin time prolonged [n = 4, EBGM: 8.11 (3.57)]. We also unexpectedly found that the usage of eplerenone may increase blood uric acid (n = 5) and lead to gout (n = 11). Due to the small number and lack of control population, it is difficult to explain whether these ADRs are related to the use of eplerenone, but we should not ignore these possible ADRs when using eplerenone.
Based on the data in the baseline table, we could see that the incidence of ADRs in males is more than twice that in females. Therefore, gender differences must be considered when evaluating eplerenone-related ADRs. In order to further investigate the correlation between gender and ADRs, we further refined the gender-based subgroup analysis. From the results, we can observe that ear and labyrinth disorders, such as ear discomfort, vertigo, and infections and infestations disorders, such as giardiasis, escherichia sepsis, gastroenteritis were only observed in males. Renal And Urinary Disorders are more common in males, which may be due to differences in susceptibility to kidney disease between males and females (Ciarambino et al., 2022). Compared with males, the severity of ADRs in females is less, which may be due to the fact that females are more concerned about the abnormal performances of the body and actively seek medical treatment, while males are more inclined to not take intervention measures and wait for symptoms to resolve on their own, which may lead to further development of the disease (Lee et al., 2023). We noticed that the ADRs of the skin and subcutaneous tissue disorders were completely different in males and females, which may be due to the different sensitivity of the skin hair follicles to MR-mediated signaling in males and females (Hundt et al., 2019). These findings highlight the importance of paying attention to ADRs in patients of different genders in clinical practice. However, it is important to emphasize that more clinical evidence is needed to validate our findings.
Although this study identified many ADRs that are not currently of concern, there are inevitably some limitations to our study. Firstly, FAERS database is a spontaneous reporting database and there may be missing cases, so the database may not be complete and is not fully representative of real-world adverse reaction rates. Secondly, the drug-related ADRs obtained using these four algorithms only demonstrate that they are correlated, but whether there is a direct causal relationship between the drug and the adverse reaction requires further research. Thirdly, the FDA analyzes all collected adverse drug-related events, but it is difficult to determine a direct causal relationship with an exact drug that may be confounded by other interacting drugs. Finally, this study has only used the FAERS database for the analysis so far and should be validated with other databases to make the results more general.
It is essential to emphasize that prior to taking any prescribed medication, including eplerenone, we should read the instructions carefully to clarify the indications, contraindications and ADRs of the medication, and to comprehend how to correctly take it. Should any adverse reactions or side effects occur, it is advisable to seek immediate medical attention or consult with a healthcare professional.
5 Conclusion
Our study used data from the FAERS database to analyze the ADRs that occurred after the use of eplerenone. We have identified a number of ADRs that are not mentioned in the drug description, mainly manifested in four SOCs, including infections and infestations, renal and urinary disorders, reproductive system and breast disorders, and hepatobiliary disorders, but cohort studies and long-term clinical studies are still needed to validate these results and take us further to comprehend the relationship between eplerenone and these ADRs. This study will bring more attention to those adverse drug reactions that exist but have not yet received attention, which may provide recommendations for the subsequent use of the drug.
