This medication belongs to a class of drugs known as nitrates. It works by relaxing and widening blood vessels so blood can flow more easily to the heart. This is the literature review of developed various analytical method for validation and estimation of Hydralazine, Isosorbide Dinitrate in combination. The analytical method like RP-HPLC (Revere Phase High Performance Liquid Chromatography), quality by design, Ultraviolet (UV) Spectrophotometry, Simultaneous Equation Method (SEM), stability indicating method were reported for Hydralazine Hydrochloride, Isosorbide Dinitrate. These analytical methods can be used for qualitative and quantitative estimation of Isosorbide Dinitrate and Hydralazine Hydrochloride in single dosage form as well as in combination with other drugs.
