Abstract

Introduction

Long-acting beta agonists and inhaled corticosteroids combination products (LABA-ICS) are widely used in the treatment of asthma. However, there appears to be little data on their cardiovascular safety. The purpose of this study was to conduct a systematic review of the available studies and trials on the cardiovascular safety of LABA-ICS in adults with asthma.

Methods

Two independent reviewers screened citations from PubMed and National Clinical Trials registry to identify studies and trials on the cardiovascular effects of LABA-ICS in patients with asthma.

Results

A total of 15 studies (with 17 cohorts on LABA-ICS to compare with a comparator or placebo) with 5,440 total study participants met the inclusion criteria. Two studies on budesonide–formoterol and one on fluticasone–salmeterol reported treatment emergent cardiovascular adverse events, all of which were dysrhythmias. For comparison, the pooled estimate of the Peto odds ratio (0.72; 95 % confidence interval [CI] 0.17–3; p = 0.65) and the summary risk ratio (0.77; 95 % CI 0.26–2.3; p = 0.64) indicated a nonsignificant difference between LABA-ICS and comparator/placebo groups.

Conclusions

Our systematic review found that few studies and trials reported treatment emergent cardiovascular adverse events with LABA-ICS. However, the Peto odds ratio and risk ratio for these outcomes was statistically nonsignificant. This suggests that LABA-ICS products may have a safe cardiovascular profile in asthma patients.

WHO estimates that half of all patients worldwide are non-adherent to their prescribed medication. The consequences of poor adherence can be catastrophic, on both the individual and population level.

Join our expert panel to discover why you need to understand the drivers of non-adherence in your patients, and how you can optimize medication adherence in your clinics to drastically improve patient outcomes.
