Beta blockers

 
There are medicines known as beta blockers. These medicines affect the way your body will respond to nerve impulses. In general, this decreases the force, along with rate, of your heart's contractions. This action can reduce blood pressure and lower the heart's oxygen demand.
 
Beta blockers are effective because they block the effects of a certain hormone called epinephrine. This is also called adrenaline. By taking beta blockers, your heart will beat with less force and beat more slowly. This results in lower blood pressure. They can be used to open blood vessels which can improve blood flow.
 
Treating high blood pressure is the main reason people take these drugs. There also types that are used to relieve chest pain as well as to stop heart attacks for those who had them in the past. They may be prescribed to treat other conditions, like tremors, migraine headaches, generalized anxiety disorder, and heartbeat irregularities. They can also be prescribed in eye drop form, to treat some types of glaucoma.

Beta receptors can be found in many places inside the body, and this includes the heart and the blood vessels. When stress hormones like adrenaline bind up with these receptors, it causes certain reactions to take place inside body. These may include:
  • Increased heart rate
