Insights
Concurrent use of sulfonylureas does not affect levosimendan's benefits in acute heart failure patients. This study found no clinically significant interactions, ensuring levosimendan efficacy is maintained in diabetic patients also taking sulfonylureas.
Area of Science:
- Cardiology
- Pharmacology
- Internal Medicine
Background:
- Levosimendan is an inodilator for acute heart failure (AHF), acting via ATP-dependent potassium channels (K(ATP) channels).
- Diabetes mellitus is prevalent in AHF patients, often treated with sulfonylureas, which block K(ATP) channels.
- Preclinical data suggested a potential interaction between levosimendan and sulfonylureas.
Purpose of the Study:
- To investigate the influence of concurrent sulfonylurea treatment on levosimendan's effects in AHF patients.
- To evaluate potential interactions impacting hemodynamics, biomarkers, and clinical outcomes.
Main Methods:
- Pooled analysis of six randomized levosimendan trials (3004 patients).
- Comparison of levosimendan effects in patients with and without concurrent sulfonylurea use.
- Evaluation of hemodynamics, BNP levels, adverse events, and survival.
Main Results:
- No clinically relevant interactions between sulfonylureas and levosimendan were detected.
- Similar hemodynamic responses (blood pressure, PCWP) and BNP reductions observed in both groups.
- Comparable survival rates and adverse event profiles between sulfonylurea users and non-users.
Conclusions:
- Concomitant use of sulfonylureas does not attenuate the hemodynamic or other effects of levosimendan.
- Levosimendan can be safely used in AHF patients also treated with sulfonylureas.
Objectives:
Levosimendan is an inodilator indicated for acute heart failure (AHF). Its vasodilatory and anti-ischemic effects are mediated by the opening of ATP-dependent potassium channels (K(ATP) channels). Diabetes mellitus is common in AHF patients and sulfonylureas are often prescribed. Sulfonylureas act by blocking the K(ATP) channels. An interaction between levosimendan and sulfonylureas has been shown in preclinical models and could be hypothesized in clinical practice.
Design:
We produced a pooled analysis of six randomized levosimendan trials (in total of 3004 patients of which 1700 were treated with levosimendan and 226 both with levosimendan and sulfonylureas) with the aim to study the influence of concurrent sulfonylurea treatment to the levosimendan effects. Invasive and non-invasive hemodynamics, biomarkers (BNP), adverse events related to myocardial ischemia, and survival were evaluated.
Results:
In our relatively small data set, we could not detect any clinically relevant interactions between the sulfonylureas and levosimendan. Similar decreases in systolic and diastolic blood pressure, pulmonary capillary wedge pressure and BNP, and similar survival and adverse event profiles were seen in sulfonylurea users and non-users exposed to levosimendan.
Conclusions:
Concomitant use of sulfonylureas with levosimendan does not attenuate the hemodynamic or other effects of levosimendan.
