Description
Monis (20mg) Tablets contain Isosorbide Mononitrate, a medication used to prevent and manage chest pain (angina pectoris) caused by coronary artery disease. It works by relaxing and widening blood vessels, allowing more oxygen-rich blood to reach the heart, reducing its workload, and preventing angina attacks.
This medicine is not for immediate relief of chest pain but is used regularly to prevent angina episodes.
