Monomil is a medication commonly prescribed for the treatment and management of angina pectoris, a condition characterized by chest pain or discomfort due to coronary heart disease. It belongs to a class of drugs known as nitrates, which work by relaxing and widening blood vessels. This action helps to increase blood flow to the heart muscle, thereby reducing the heart's workload and alleviating symptoms of angina. Monomil is typically administered in the form of tablets and should be taken as directed by a healthcare professional. It is important for patients to follow their prescription closely to effectively manage their condition and to minimize potential side effects.
