About NitroMed

NitroMed of Lexington, Massachusetts is the maker of BiDil^® (isosorbide dinitrate/hydralazine hydrochloride), an orally administered medicine available in the United States for the treatment of heart failure in self-identified black patients. In this population, BiDil is indicated as an adjunct to current standard therapies such as angiotensin converting enzyme (ACE) inhibitors and beta blockers. There is little experience in patients with New York Heart Association Class IV heart failure. BiDil was approved by the U.S. Food and Drug Administration, primarily on the basis of efficacy data from the company’s landmark A-HeFT (African American Heart Failure Trial) clinical trial.
