Beta inhibitors or beta-blockers are a group of drugs used to lower high blood pressure and treat various heart conditions, such as heart failure, arrhythmia, chest pain (angina), or heart attack.
Beta blockers work by inhibiting the effect of the hormone epinephrine or adrenaline, which is a hormone that works to increase the heart rate and trigger the work of the heart muscle. By inhibiting the hormone, the heart will beat slower and blood pressure will drop.
Beta blockers also have the effect of dilating blood vessels, so blood circulation can increase. In addition to the heart and blood vessels, beta blockers can be used to overcome migraines, glaucoma, tremors, anxiety disorders, and hyperthyroidism.
Beta blockers can only be used with a doctor's prescription and instructions.
Types of Beta Blockers
There are 3 types of beta blockers that are divided based on how they work and the side effects they cause, namely:
Nonselective beta blockers
Nonselective beta blockers work by blocking beta-1 and beta-2 receptors, thus affecting the heart, blood vessels, and respiratory tract. This drug can cause side effects in the form of narrowing of the respiratory tract, making it dangerous for asthma or COPD sufferers .
Examples of nonselective beta blockers are:
Selective beta blockers
Selective beta blockers work by blocking only beta-1 receptors in the heart. This drug does not affect the respiratory tract. Examples of selective beta blockers are:
Third generation beta blockers
This beta blocker not only inhibits the beta-1 receptor, but also the alpha receptor, so it has the effect of dilating blood vessels and lowering blood pressure. Examples of third generation beta blockers are:
