Angiotensin Receptor II receptor blockers are medications for treating heart failure, chronic kidney, and high blood pressure. This medication is also prescribed by a doctor after a heart attack.

A recent study published by the Centers for Disease Control and Prevention, one in every three Americans are dealing with high blood pressure, and only 54% have their control over this prevalent medical condition.

High blood pressure has damaging effects on the body, especially the heart health and contributes to several other problems. This is where the angiotensin receptor antibodies are helpful in efficiently maintaining the blood pressure.

How The Angiotensin Receptor II Antibody Works?

The blood vessels are responsible for supplying oxygen and blood to the heart, the constant supply helps in the optimal functioning of the heart.

Angiotensin II is the hormone prepared withing the body and does the job of tightening the blood vessels. Further, this hormone leads to water and salt retention, thereby as the content of salt in the blood increases, the body’s blood pressure also spikes significantly.

This is where the ARBs or angiotensin receptor antibody come into play to limit the production of angiotensin II in the body. The ARBs perform this function by blocking the receptors those responsible for the production of Angiotensin II, these receptors are known as AT1 and are present in kidneys, blood vessels, and heart.

With the release of the angiotensin II, the blood vessels become too narrow, therefore, it causes greater pressure as the blood is supplied to the heart. Now, when the ARBs blacks the receptors forming angiotensin II, the blood vessels tightening is significantly lowered.

When Doctors Prescribe the ARBs?

Here, are the various conditions under the doctor may recommend you to take ARBs, and a handful of these are highlighted below: –

  • After having a heart attack
  • Having a Kidney Trouble
  • Angiotensin Receptor Antibody
  • Abnormal Obesity

Unpleasant Side Effects From Ace Inhibitors

Typically, doctors advise their patients to have one dose of ARBs daily, ideally early in the morning. If you have chronic high blood pressure or if the levels vary throughout the day, then your physician may prescribe twice-daily dose, and there is no thumb rule that the ARBs have to be taken only in the morning.

Unlike ACE, there are no side effects associated with taking ARBs.

Perks of Taking Prescribed ARBs Dose

There are many benefits of taking an angiotensin receptor antibody, and a few of these include lowering the risk of heart attack, cardiac arrest or stroke.

If you are having any kidney disease, then you must take ARBs, it is one amongst the most effective medication for curing high blood pressure. Numerous studies done over the animals have suggested that the intake of ARBs is best for protecting the cognitive decline.

Sometimes, the doctor may advise their patient to try ACE inhibitors first, then move to ARBs in case there is any side effect with the former medication.

Side Effects of the ARBs

Here, are the common side effects of the ARBs: –

  • Headache
  • Body Fatigue
  • Respiratory Symptoms
  • Vomiting and Diarrhea
  • Slight Back Pain
  • Leg Swelling
  • High Potassium Levels

One thing you need to note here is that there are certain drugs that you must not take with ARBs, your doctor will best advise you on this.

Never take ACE and ARBs must note be taken in combination, as this may increase the risk of low blood pressure, kidney damage, and increased potassium levels.

The angiotensin receptor antibody is not recommended for pregnant women or planning to get pregnant in the near future. Several medical studies have also shown ARBs are not best-suited for elderly people. It is best to speak to your doctor beforehand before taking the ARBs medication.


You have to note that each body reacts differently to the ARBs medication, therefore start with a small dose. If you experience any side effects, talk your physician right away.
