Monomack is used to prevent angina attacks and chest pain caused by decreased blood flow to the heart. The drug works by widening the blood vessels, which improves blood flow and reduces stress on the heart.
Monomack may also be prescribed in some cases to manage symptoms of chronic heart failure or to prevent complications associated with heart disease. However, the drug is not used to treat angina attacks while they occur, but is taken regularly as a long-term preventive treatment.
