Nicorandil is a medication used to treat angina, a condition characterized by chest pain that occurs when the heart muscle doesn't get enough oxygen. This medication works by relaxing the blood vessels, allowing more blood and oxygen to flow to the heart muscle. Some synonyms for Nicorandil include Ikorel, Aprior, and Nitorubin. These synonyms are often used interchangeably with Nicorandil by healthcare professionals and pharmacists. It is important to note, however, that while these drugs may have similar applications, they may have different dosages, side effects, and contraindications. As such, patients should always consult their healthcare provider before switching between medications or using different drugs.
