Definitions
- the present invention relates, generally, to methods of treatment 'and prophylaxis of atrial fibrillation in a subject, utilizing omega-3 fatty acids in a loading dose and thereafter in a maintenance dose.
- Atrial fibrillation is one of the most common cardiac arrhythmias in humans, and it accounts for approximately one-third of hospitalizations for cardiac rhythm disturbance. It is estimated that two to three million people in America have this condition, and billions of dollars are spent on diagnosis and treatment. In addition, half a million new cases are diagnosed every year.
- Atrial fibrillation is a rhythm disturbance of the atria characterized by rapid, uncoordinated contractions resulting from abnormal electrical discharges in the heart. This results in a reduced ability of the atria to pump blood into the ventricles and often a pooling of blood occurs in parts of the atria. The stagnation of blood can result in the formation of clots, which can then travel through the blood vessels and cause blockage.
- Atrial fibrillation may increase the risk of stroke, ventricular arrhythmias, need for pacemaker therapy, and use of potentially harmful drugs.
- Most people with atrial fibrillation have an underlying chronic cardiovascular condition, such as high blood pressure, coronary artery disease, i or diseases of the heart valves or the heart muscle.
- atrial fibrillation can be caused by an acute reversible event such as the intake of certain drugs, physical or psychological stress, myocardial infarction, pericarditis, hyperthyroidism, or pulmonary embolism.
- Atrial fibrillation is also commonly developed after surgery, such as heart, thoracic, abdominal, hip, and other surgeries and procedures. In fact, atrial fibrillation is the most common complication after coronary artery bypass graft (CABG) surgery. There is a 10 - 15% incidence in this setting, and it is also manifested more commonly in the elderly.
- CABG coronary artery bypass graft
- Treatment options for atrial fibrillation include pharmacological and non- pharmacological methods.
- Pharmacological treatments include drugs which decrease the heart rate, such as digoxin, beta blockers, and calcium channel blockers.
- Anticoagulants such as warfarin may also be used to decrease the risk of clot formation associated with atrial fibrillation.
- Electrical cardioversion and chemical cardioversion with drugs such as sotalol, amiodarone, propafenone, fleicanide, disopyramide, and dofetilide are often performed to restore and maintain a normal sinus rhythm.
- omega-3 fatty acid is a concentrate of omega-3, long chain, polyunsaturated fatty acids from fish oil containing DHA and EPA is sold under the trademark LOVAZATM.
- LOVAZATM a form of omega-3 fatty acid is described, for example, in U.S. Patent Nos. 5,502,077, 5,656,667 and 5,698,594, each ⁇ incorporated herein by reference.
- the use of a loading dose is often used when the time to reach steady state concentrations is appreciable, or when therapeutic levels must be achieved rapidly.
- the loading dose is used to "load” or "fill up” the volume of distribution with the drug.
- the volume of distribution is the proportionality factor that relates the total amount of drug in the body to the concentration in the plasma. It describes the drug's ability to distribute over the body from the blood to the tissues. The time required for the drug to accumulate in the body is referred to as the drug's half-life.
- the half-life of a drug is the time it takes for the plasma concentration of a drug to reach half of its original concentration at time zero, and it often helps to determine whether there is a need to provide a loading dose.
- One study by Katan et al. found that the mean half-life of EPA and DHA into plasma cholesteryl esters as fatty acids was 4.8 days and 10.3 days, respectively. The same study found that the mean half-life of EPA and DHA in erythrocytes as fatty acids was 28.1 days and 38.5 days, respectively.
- Katan et al. Kinetics of the incorporation of dietary fatty acids into serum cholesteryl esters, erythrocyte membranes, and adipose tissue: an 18-month controlled study.
- omega-3 fatty acids are not classical and that free EPA, DHA, and/or ethyl esters thereof are not present in the blood in amounts anywhere near the relative amount ingested. Omega-3 fatty acids tend to be metabolized extensively in first pass in the liver for presentation and/or utilization in a broad range of biologically useful forms. As the kinetics of EPA and DHA are not classical (for example, the kinetics are dependent on the form of EPA and DHA and the location, such as erythrocyte membrane, serum cholesteruyl esters, adipose tissue), Katan et al. does not disclose establishing therapeutic levels of omega-3 fatty acids at an early point in therapy.
- omega-3 fatty acids have anti- coagulatory effects which may have negative interactions with other active agents (for example, warfarin) or may potentially increase bleeding risk during or after surgery or other procedures. See, for example, Buckley et al., Ann
- EPA and/or DHA is causing anti-arrhythmic activity post-surgery.
- DHA and EPA may have a beneficial effect in both the prophylaxis and treatment of atrial fibrillation. Consequently, there is a need in the art for a therapeutic regimen that includes the administration of DHA and EPA before a procedure which is known to be associated with the risk of atrial fibrillation, or at the beginning of more long-term treatment of atrial fibrillation.
- a therapeutic regimen that includes the administration of DHA and EPA before a procedure which is known to be associated with the risk of atrial fibrillation, or at the beginning of more long-term treatment of atrial fibrillation.
- Embodiments of the present invention address the above-mentioned need for a therapeutic regimen for the treatment and prophylaxis of atrial fibrillation, which achieves therapeutic levels of omega-3 fatty acids at an early point in therapy.
- One embodiment of the present invention is a method of treating or preventing atrial fibrillation in a subject, the method comprising administering to the subject an effective amount of omega-3 fatty acids in a loading dose amount for a loading dose period of 1 to 30 days, and thereafter in a maintenance dose amount, wherein the loading dose amount is about twice the maintenance dose amount or more.
- Another embodiment of the present invention is a method of preventing atrial fibrillation in a subject after an interventional procedure, the method comprising administering an effective amount of omega-3 fatty acids in a loading dose amount for a loading dose period of 1 to 30 days before or immediately after the interventional procedure, and thereafter in a maintenance dose amount after the interventional procedure, wherein the loading dose amount is about twice the maintenance dose amount or more.
- Another embodiment of the invention is a method of treating atrial fibrillation in a subject, the method comprising administering to the subject an effective amount of omega-3 fatty acids in a loading dose amount for a loading dose period of 1 to 30 days, and thereafter a maintenance dose amount, wherein the amount of the loading dose is about twice the maintenance dose amount or more.
- the goal of such therapy is the reduction of atrial fibrillation time or occurrences in these subjects.
- One such group of individuals with atrial fibrillation who would benefit from this therapy is patients with pacemakers for conditions such as atrioventricular node dysfunction and block, sinus node dysfunction, sinoatrial bradycardia disease, bradytachycardia syndrome, cardiac decompensation, chronic heart failure, chronic bifascicular and trifascicular block, hypertrophic obstructive cardiomyopathy, idiopathic dilated cardiomyopathy, long-QT syndrome, hypersensitive carotid sinus, and neurocardiogenic syncope.
- the present invention relates to methods of treatment and prophylaxis of atrial fibrillation, utilizing omega-3 fatty acids in a loading dose and thereafter in a maintenance dose.
- Atrial fibrillation refers to a supraventricular tachyarrhythmia characterized by uncoordinated atrial activation with consequent deterioration of atrial mechanical function, as discussed in the ACC/AHA/ESC Guidelines for the Management of Patients with Atrial Fibrillation (J Am Coll Cardiol. 2001. 38(4):1266i-1266lxx). Atrial fibrillation is characterized on an electrocardiogram (ECG) by the replacement of consistent P waves by rapid oscillations or fibrillatory waves that vary in size, shape, and timing, associated with an irregular, frequently rapid ventricular response when atrioventricular (AV) conduction is intact. Examples of different types of atrial fibrillation are acute, chronic, paroxysmal, intermittent, constant, persistent, and permanent.
- the term “loading dose” refers to an initial dose given at the start of therapy.
- the term “maintenance dose” refers to the dose given after the loading dose or doses. In the presently claimed invention, the loading dose can be about twice the maintenance dose or more.
