What is metoprolol used to treat?

Metoprolol is specifically classified as a beta-blocker, which is a type of medication commonly used in clinical practice to manage various cardiovascular conditions. It is particularly effective in treating angina, which is chest pain caused by reduced blood flow to the heart muscle, and hypertension, or high blood pressure, which is a major risk factor for heart disease and stroke. By blocking certain receptors in the heart, metoprolol reduces heart rate and the force of heart muscle contractions, leading to lower blood pressure and reduced oxygen demand by the heart.

In contrast to other options, metoprolol is not indicated for the treatment of anemia, diabetes, or cholesterol levels. Anemia involves a deficiency of red blood cells or hemoglobin, diabetes is a metabolic disorder affecting blood sugar levels, and the management of cholesterol and triglycerides typically involves other classes of medications, such as statins. Thus, metoprolol's primary use is accurately reflected in the option addressing angina and hypertension.
