METHODS OF ADMINISTRATION OF SINGLE DOSES OF VANOXERINE TO TERMINATE ACUTE EPISODES OF CARDIAC ARRHYTHMIA
Compositions and methods of treating patients suffering from symptoms of recent onset atrial fibrillation or atrial flutter comprising administration of a single dose of about 200 to about 400 mg of vanoxerine to return said patient to normal sinus rhythm in less than about 24 hours.
1 . A method for restoring normal sinus rhythm to a patient suffering from recent onset symptomatic atrial fibrillation or atrial flutter in less than about 24 hours by administering to said patient at least 200 mg of vanoxerine.
2 . The method of claim 1 comprising at least 300 mg of vanoxerine.
3 . The method of claim 1 comprising at least 400 mg of vanoxerine.
4 . The method of claim 1 wherein the patient is returned to normal sinus rhythm in less than about 12 hours.
5 . The method of claim 1 wherein the patient is returned to normal sinus rhythm in less than about 8 hours.
6 . The method of claim 1 wherein the patient is returned to normal sinus rhythm in less than about 4 hours.
7 . A method of treating a patient suffering from symptoms of atrial fibrillation or atrial flutter for less than about 72 hours comprising administration of about 200 to about 400 mg of vanoxerine.
8 . The method of claim 7 wherein said patient is suffering from atrial fibrillation or atrial flutter symptoms for less than about 48 hours.
9 . The method of claim 7 wherein said patient is suffering from atrial fibrillation or atrial flutter symptoms for less than about 24 hours.
10 . The method of claim 7 wherein said patient is returned to normal sinus rhythm in less than about 24 hours.
11 . The method of claim 7 wherein said patient is returned to normal sinus rhythm in less than about 8 hours.
12 . A method of treating a patient having recent onset of AF or AFL comprising administration of a single dose of a pharmaceutical composition comprising about 200 to about 400 mg of vanoxerine, and wherein said patient is converted to normal sinus rhythm at a rate of at least 33% better than conversion as compared to placebo at a time period of 0-4 hours.
13 . The method of claim 12 wherein the time period is from 0-8 hours.
14 . The method of claim 12 wherein the time period is from about 0-24 hours.
15 . The method of claim 12 wherein the conversion is at least 50% better than conversion as compared to placebo at a time period of 0-4 hours.
16 . The method of claim 12 wherein the conversion is at least 50% better than conversion as compared to placebo at a time period of 0-8 hours.
17 . The method of claim 12 wherein the conversion is at least 50% better than conversion as compared to placebo at a time period of 0-24 hours.
18 . The method of claim 12 wherein the conversion is at least 100% better than conversion as compared to placebo at a time period of 0-4 hours.
19 . The method of claim 12 wherein the conversion is at least 100% better than conversion as compared to placebo at a time period of 0-8 hours.
20 . The method of claim 12 wherein the conversion is at least 100% better than conversion as compared to placebo at a time period of 0-24 hours.
21 . A method for terminating atrial flutter or atrial fibrillation comprising:
a. administering a first dose of at least 200 mg of vanoxerine to a patient to terminate said atrial flutter or atrial fibrillation in less than about 24 hours;
b. administering a subsequent dose of an effective amount of vanoxerine to achieve steady state in the patient; and
c. administering an effective amount of vanoxerine to maintain steady state in the patient.
