Which medication is classified as a beta blocker?

Metoprolol is classified as a beta blocker, which is a type of medication that primarily affects the heart by blocking beta-adrenergic receptors. This action results in a decrease in heart rate and blood pressure, making beta blockers effective in treating a variety of cardiovascular conditions, such as hypertension, heart failure, and angina. They can also be used for managing certain types of arrhythmias and for the prevention of migraines.

The classification of medications relies on their pharmacological properties and the systems they influence. Beta blockers like metoprolol work by interfering with the response of tissues to certain neurotransmitters, leading to a calming effect on the heart. By understanding how these medications work, it becomes clearer how they can be applied in clinical practice for the management of cardiac-related issues.
