Metoprolol: Uses, Side Effects, Safety, Recalls and More

What is Metoprolol?

Metoprolol is a medication primarily used to treat high blood pressure (hypertension), angina (chest pain), and certain types of heart conditions, such as heart failure and heart rhythm disorders like atrial fibrillation. It belongs to a class of drugs known as beta-blockers.

Metoprolol works by blocking the effects of adrenaline (epinephrine) on the heart, thereby slowing the heart rate, reducing the force of heart muscle contraction, and lowering blood pressure. This helps to decrease the workload on the heart and improve its efficiency in pumping blood throughout the body.

There are different formulations of metoprolol available, including immediate-release tablets, extended-release tablets, and intravenous formulations. The choice of formulation depends on the specific condition being treated and individual patient factors.

In addition to its cardiovascular uses, metoprolol may also be prescribed for certain off-label purposes, such as migraine prevention and anxiety management. However, its primary indications remain in the treatment of cardiovascular disorders.
