What is ARBs?

Angiotensin II receptor blockers, or ARBs for short, are a class of medications used to treat hypertension, or high blood pressure, and other conditions such as heart failure and diabetic kidney disease. ARBs work by blocking the action of a hormone called angiotensin II, which causes blood vessels to narrow and blood pressure to increase.

Angiotensin II is produced in the body by an enzyme called angiotensin converting enzyme, or ACE. Another class of medications known as ACE inhibitors also work by blocking the production of angiotensin II, but ARBs act by binding to the receptors in the body that angiotensin II normally attaches to, thus preventing its effects.

By blocking the effects of angiotensin II, ARBs cause blood vessels to relax and widen, reducing blood pressure and improving blood flow. This can help reduce the risk of complications associated with high blood pressure such as heart attack, stroke, and kidney damage.

ARBs are typically taken orally in the form of tablets or capsules, and are available in several different formulations. Some common ARBs include losartan, valsartan, and candesartan.

While ARBs are generally well-tolerated, like all medications, they can cause side effects in some people. Common side effects of ARBs may include dizziness, fatigue, headache, and nausea. More serious side effects are rare but may include allergic reactions, low blood pressure, and kidney problems.

ARBs may also interact with other medications, including certain diuretics, potassium supplements, and nonsteroidal anti-inflammatory drugs (NSAIDs). It is important to inform your healthcare provider of all medications you are taking before starting an ARB.

In conclusion, ARBs are a class of medications used to treat hypertension and other conditions by blocking the effects of the hormone angiotensin II. They are generally well-tolerated but can cause side effects in some people. ARBs may interact with other medications, and it is important to inform your healthcare provider of all medications you are taking before starting an ARB. ARBs are an effective treatment for hypertension and can help reduce the risk of complications associated with high blood pressure.
