Other Comments
There is no adequate experience in heart failure with doses of the combination product other than those recommended and no experience with the use of the individual components.
The combination of hydralazine-isosorbide dinitrate, in addition to standard therapy, is a reasonable alternative in patients with chronic heart failure who cannot be given an angiotensin converting enzyme inhibitor or an angiotensin II receptor blocker because of drug intolerance, lack of efficacy, hypotension, or renal insufficiency.
The combination of hydralazine-isosorbide dinitrate is particularly effective in black patients with heart failure who tend to be less responsive to angiotensin-converting enzyme inhibitors, which are part of standard therapy for heart failure.
