Isosorbide mononitrate extended-release tablets are a prescription medication used to prevent angina (chest pain) in individuals with coronary artery disease or other forms of heart disease. It belongs to a class of drugs known as nitrates, which work by relaxing and widening blood vessels. This improves oxygen delivery to the heart and reduces the heart’s workload, helping to prevent chest pain before it starts.
Unlike short-acting nitrates used to relieve acute chest pain, isosorbide mononitrate ER is designed for long-term prevention and is typically taken once daily. The extended-release formulation maintains steady blood levels of the medication throughout the day to provide continuous protection against angina episodes.
For best results, the medication should be taken at the same time each day. Alcohol and some medications may increase its blood pressure-lowering effects, so it’s important to follow your provider’s guidance on safe use.
