In medicine, there are several types of receptor types. For example, when it comes to cancer, several types of receptors exist within the body. One type is the beta receptor. The beta receptor can be described as a group of proteins. The beta receptor is located on the surface of the cell.

Summary Table

Beta 1 Beta 2
Found in the heart and brain. Found in the digestive tract, uterus, muscles, lungs, and so forth.
Used to treat high blood pressure and other cardiovascular diseases. Responsible for treating any dysfunction of smooth muscles.

Difference Between Beta 1 and Beta 2

There are several types of beta receptors. One type is called a beta-2 receptor. The beta-2 receptor is very similar to the beta-1 receptor, but there are differences between them. Beta-1 and beta-2 receptors have different roles in our bodies.

Let’s take a closer look at the differences between beta 1 and beta 2 receptors to understand their roles more clearly.


Beta receptors can be found throughout our bodies, including the liver, pancreas, heart, brain, muscles, fat tissue, and skeletal muscle tissue.

These receptors are very important for us as they have an important role in our body’s metabolism process as well as in controlling many metabolic functions within our body like blood sugar levels or blood pressure levels etc.

When we have too much of something and our body can’t regulate it, doctors can prescribe us medicines called beta-blockers.

Beta-blockers can help lower your blood pressure, prevent heart attacks, and treat a variety of heart-healthy conditions. They can cause glaucoma, and migraines, and cause you to feel anxious.

Beta-blockers reduce high cholesterol in the body by slowing down the effects of stress hormones on the heart.

Difference Between Beta 1 and Beta 2

We can find Beta 1 receptors in the heart and brain. Meanwhile, Beta 2 receptors are often found in the digestive tract, uterus, muscles, lungs, and other places.

The main difference between each respective blocker is that beta-1 blockers are used to treat high blood pressure and other conditions in which the heart is not working as it should. Beta-2 blockers are used to treat high blood pressure, bronchospasm, angina pectoris, heart arrhythmias, and other conditions.

In beta-blockers, the parent drug is propranolol (Inderal). The active ingredient in beta-blockers is a beta-adrenergic receptor blocker. It blocks the effects of epinephrine on the cardiac muscle and other smooth muscles in the body.

For more people, beta-blockers are a drug of choice, but they have side effects. This is why they are sometimes prescribed other medications.
