Final answer:
Metoprolol is a medication used to treat high blood pressure, chest pain, and abnormal heart rhythms. It works by blocking beta-receptors, allowing blood vessels to dilate and reducing heart rate. It is commonly prescribed to improve symptoms of cardiovascular conditions including high blood pressure and heart failure.
Step-by-step explanation:
Metoprolol is used to treat high blood pressure, chest pain (angina) caused by reduced blood supply to the heart muscle, and some arrhythmias (abnormal heart rhythms). It is a medication that belongs to the class of drugs called beta-blockers. These drugs work by blocking the beta-receptors associated with vasoconstriction and cardioacceleration, allowing blood vessels to dilate and keeping heart rate from increasing. Metoprolol is commonly prescribed to improve symptoms of cardiovascular conditions including high blood pressure and heart failure.
