# A real-world pharmacovigilance analysis of acute renal failure associated with sacubitril/valsartan based on FDA Adverse Event Reporting System (FAERS)

## TL;DR

This study uses real-world data to analyze the risk of acute kidney failure linked to the drug sacubitril/valsartan, finding a significant association.

## Contribution

The study provides new evidence on the acute renal failure risk of sacubitril/valsartan using FAERS data and multiple statistical methods.

## Key findings

- Sacubitril/valsartan showed a significant association with acute renal failure using multiple disproportionality analysis algorithms.
- Hospitalization rates were 14.33% for narrow and 30.69% for broad acute renal failure cases.
- Most adverse events occurred within 30 days of drug use, with a median patient age of 71.

## Abstract

The renal safety profile of sacubitril/valsartan remains debated in clinical practice. To address this uncertainty, we conducted a pharmacovigilance analysis of acute renal adverse events associated with sacubitril/valsartan using the FDA Adverse Event Reporting System (FAERS) database.

Using data from the FAERS database, we conducted an observational pharmacovigilance study from the first quarter (Q1) of 2015 to the fourth quarter of 2024 (Q4). The disproportionality analysis was performed using four algorithms: the reporting odds ratio (ROR), the proportional reporting ratio (PRR), the Bayesian confidence propagation neural network (BCPNN), and the multi-item gamma Poisson shrinker (MGPS).

A total of 16,144,939 adverse events (AEs) were available on FAERS database, among these, 132,255 cases were associated with sacubitril/valsartan, 2,205 cases related to narrow acute renal failure (SMQs) and 3,232 cases with broad SMQs. And sacubitril/valsartan and acute renal adverse showed significant association both in narrow SMQs (ROR = 2.37; PRR = 2.34, χ2 = 1703.73; EBGM05 = 2.26) and the broad SMQs (ROR = 2.55, PRR = 2.51, χ2 = 2941.80, EBGM05 = 2.43). A total of 10 (19.23% of total) positive signals were obtained using the above four algorithms. Median age was 71 years, time to onset was within 30 days, and hospitalization rates of acute renal failure outcomes were 14.33% (narrow SMQs) and 30.69% (broad SMQs).

The widespread use of sacubitril/valsartan has raised safety concerns, particularly regarding acute renal failure. Our study, leveraging real-world FAERS data, systematically analyzed this association, providing new evidence on acute renal failure risks.
