Albuterol is a bronchodilator that is commonly used to treat asthma and other respiratory conditions. The drug works by relaxing the muscles in the airways which allows the airways to open up and makes it easier to breathe.
Albuterol is a beta-2 agonist which means that it stimulates the beta-2 receptors in the body. These receptors are found in the lungs and are responsible for relaxing the smooth muscle in the airways.
When albuterol binds to the beta-2 receptors it causes the lungs to open up and makes it easier to breathe. However albuterol also has some other effects on the body including an increase in heart rate.
The reason why albuterol increases heart rate is not fully understood but it is thought to be due to the drug’s effects on the nervous system. Albuterol causes the body to release norepinephrine which is a hormone that increases heart rate and blood pressure.
While the increase in heart rate can be concerning it is usually not harmful and goes away once the drug is stopped. However if you have high blood pressure or heart disease you should talk to your doctor before using albuterol.
