Treatment of cardiac arrhythmias with GLP-1 receptor ligands
View Patent ↗Compositions of the invention, including compounds that bind to a receptor for a glucagon-like peptide-1, an incretin, a glucagon-like peptide-1 (GLP-1), an exendin, or an agonist, an analog (preferably an agonist analog), a derivative, or a variant of any of aforementioned compounds, are used in the prevention and treatment of arrhythmias associated with cardiac ischemia, cardiac ischemia-perfusion and/or congestive heart failure. The invention relates to both the method and compositions for such treatment.
1. A method for treating arrhythmias comprising:
administering to an individual in need of such treatment an amount of a composition effective to treat arrhythmias,
said composition comprising glucagon-like peptide 1(GLP-1), exendin-4, or an analog having at least 90% amino acid sequence homology to GLP-1 or exendin-4, and that binds to a receptor for GLP-1; and
thereby treating said arrhythmias.
2. The method of claim 1 wherein the composition is administered in a dose of from about 0.1 pmol/kg/min. up to about 10 pmol/kg/min.
3. The method of claim 1 wherein the composition is administered in a dose of from about 0.01 pmol/kg to 20 nmol/kg.
4. The method of claim 1 wherein the composition is administered as a single injection in a dose of from about 0.005 nmol/kg to 20 nmol/kg.
5. The method of claim 1 wherein the composition is administered concurrently with glucose.
6. The method of claim 1 wherein the composition is administered concurrently with potassium.
7. The method of claim 1 wherein the composition is administered concurrently with a free radical scavenger.
8. The method of claim 1 wherein the composition is administered within four hours of an ischemic event.
9. The method of claim 8 wherein the composition continues to be administered following the ischemic event.
10. The method of claim 1 wherein the composition is administered concurrently or as soon as possible following therapies that reestablish flow in an artery that has been obstructed.
11. The method of claim 1 wherein the composition is administered following a cardiac intervention selected from the group consisting of angioplasty, coronary bypass grafting, and placement of an intracoronary stent.
12. The method of claim 11 wherein the composition continues to be administered following the intervention.
13. The method of claim 1 wherein the composition is administered to treat ventricular arrhythmias.
14. The method of claim 13 wherein the ventricular arrhythmia is caused by a condition selected from the group consisting of cardiac ischemia, cardiac ischemia-reperfusion, and congestive heart failure.
