ABSTRACT:
FIELD OF THE INVENTION
The present invention provides methods of treating and/or preventing vascular diseases characterized by nitric oxide insufficiency by administering a therapeutically effective amount of at least one antioxidant or a pharmaceutically acceptable salt thereof, and at least one of isosorbide dinitrate and isosorbide mononitrate, and, optionally, at least one nitrosated angiotensin-converting enzyme inhibitor, nitrosated beta-adrenergic blocker, nitrosated calcium channel blocker, nitrosated endothelin antagonist, nitrosated angiotensin II receptor antagonist, nitrosated renin inhibitor, and/or at least one compound used to treat cardiovascular diseases. The antioxidant is preferably a hydralazine compound or a pharmaceutically acceptable salt thereof. The present invention also provides methods of treating and/or preventing vascular diseases characterized by nitric oxide insufficiency by administering a therapeutically effective amount of at least one nitrosated angiotensin-converting enzyme inhibitor, nitrosated beta-adrenergic blocker, nitrosated calcium channel blocker, nitrosated endothelin antagonist, nitrosated angiotensin II receptor antagonist and/or nitrosated renin inhibitor, and, optionally, at least one antioxidant and/or at least one compound used to treat cardiovascular diseases. The present invention also provides methods of treating and/or preventing Raynaud's syndrome by administering a therapeutically effective amount of at least one antioxidant or a pharmaceutically acceptable salt thereof

and at least one of isosorbide dinitrate and isosorbide mononitrate, and/or at least one nitrosated angiotensin-converting enzyme inhibitor, nitrosated calcium channel blocker, nitrosated endothelin antagonist, nitrosated angiotensin II receptor antagonist and/or nitrosated renin inhibitor. The present invention also provides novel transdermal patches comprising at least one antioxidant or a pharmaceutically acceptable salt thereof

and at least one of isosorbide dinitrate and isosorbide mononitrate, and/or at least one nitrosated angiotensin-converting enzyme inhibitor, nitrosated beta-adrenergic blocker, nitrosated calcium channel blocker, nitrosated endothelin antagonist, nitrosated angiotensin II receptor antagonist and/or nitrosated renin inhibitor.
BACKGROUND OF THE INVENTION
The decline in cardiovascular morbidity and mortality in the United States over the past three decades has been the result of significant advances in research on cardiovascular disease mechanisms and therapeutic strategies. The incidence and prevalence of myocardial infarction and death from myocardial infarction, as well as that from cerebrovascular accident, have decreased significantly over this period largely owing to advances in prevention, early diagnosis, and treatment of these very common diseases.
Analysis of outcomes by race, however, paints quite a different picture: life expectancy and cardiovascular morbidity rates have improved far less for blacks than whites. Available data show that the likelihood of dying from cardiovascular disease is far greater among black Americans than among white Americans. In this decade, the death rate from cardiovascular disease for black males was 353 per 100,000 population, while that for white males was 244 per 100,000; the rate for black females was 226 per 100,000; while that for white females was 135 per 100,000. Consonant with this important demographic parameter is the observation that there is a higher prevalence of several of the important risk factors for cardiovascular disease, e.g., hypertension, smoking, diabetes mellitus, obesity, and left ventricular hypertrophy, among blacks compared with whites. In addition, outcomes of cardiovascular events are worse for blacks than whites. Following myocardial infarction, blacks have a 50% higher annual mortality rate than whites, and their five year survival is only 70%. Thus, the many advances in cardiovascular medicine that account for the overall improvement in cardiovascular health in the general population have failed to translate into comparable racial benefits.
There is a need in the art for new and more effective compositions and methods for treating vascular diseases. The present invention is directed to these, as well as other, important ends.
SUMMARY OF THE INVENTION
The present invention provides methods for treating and/or preventing vascular diseases characterized by nitric oxide insufficiency by administering to a patient a therapeutically effective amount of at least one antioxidant or a pharmaceutically acceptable salt thereof
7
and at least one of isosorbide dinitrate and isosorbide mononitrate, and, optionally, at least one nitrosated angiotensin-converting enzyme inhibitor, nitrosated beta-adrenergic blocker, nitrosated calcium channel blocker, nitrosated endothelin antagonist, nitrosated angiotensin II receptor antagonist, nitrosated renin inhibitor, and/or at least one compound used to treat cardiovascular diseases. The antioxidant is preferably a hydralazine compound or a pharmaceutically acceptable salt thereof. The vascular diseases characterized by nitric oxide insufficiency include, for example, hypertension (e.g., low-renin hypertension; salt-sensitive hypertension; low-renin, salt-sensitive hypertension; primary pulmonary hypertension; thromboembolic pulmonary hypertension; pregnancy-induced hypertension; renovascular hypertension), heart failure (e.g., microvascular cardiac ischemia), and left ventricular hypertrophy with disproportionate microvascularization, (i.e., inadequate vascularity) or diastolic dysfunction. The antioxidant and the isosorbide dinitrate or isosorbide mononitrate and optional nitrosated compound and/or compound used to treat cardiovascular diseases can be administered separately or as components of the same composition.
Another aspect of the present invention provides methods for treating and/or preventing vascular diseases characterized by nitric oxide insufficiency by administering to a patient a therapeutically effective amount of at least one nitrosated angiotensin-converting enzyme inhibitor, nitrosated beta-adrenergic blocker, nitrosated calcium channel blocker, nitrosated endothelin antagonist, nitrosated angiotensin II receptor antagonist and/or nitrosated renin inhibitor, and, optionally, at least one antioxidant and/or at least one compound used to treat cardiovascular diseases. The vascular diseases characterized by nitric oxide insufficiency include, for example, hypertension (e.g., low-renin hypertension; salt-sensitive hypertension; low-renin, salt-sensitive hypertension; primary pulmonary hypertension; thromboembolic pulmonary hypertension; pregnancy-induced hypertension; renovascular hypertension), heart failure (e.g., microvascular cardiac ischemia), and left ventricular hypertrophy with disproportionate microvascularization, (i.e., inadequate vascularity) or diastolic dysfunction. The nitrosated compound and optional antioxidant and/or compound used to treat cardiovascular diseases can be administered separately or as components of the same composition.
In another aspect, the present invention provides methods for treating and/or preventing Raynaud's syndrome by administering to a patient a therapeutically effective amount of at least one antioxidant or a pharmaceutically acceptable salt thereof

and at least one of isosorbide dinitrate and isosorbide mononitrate and/or at least one nitrosated angiotensin-converting enzyme inhibitor, nitrosated calcium channel blocker, nitrosated endothelin antagonist, nitrosated angiotensin II receptor antagonist and/or nitrosated renin inhibitor. The antioxidant, isosorbide dinitrate or isosorbide mononitrate, and nitrosated compound can be administered separately or as components of the same composition.
In yet another aspect, the present invention provides novel transdermal patches comprising a therapeutically effective amount of at least one antioxidant at least one of isosorbide dinitrate and isosorbide mononitrate and/or at least one nitrosated angiote
