What is Telmisartan and How Does it Work?
Telmisartan is a medication belonging to a class of drugs known as angiotensin II receptor blockers (ARBs). It functions by preventing angiotensin II, a natural chemical in the body, from narrowing blood vessels. This action allows blood vessels to widen, which lowers blood pressure and reduces the workload on the heart. Telmisartan is prescribed to treat high blood pressure (hypertension) and to reduce the risk of stroke, heart attack, and death in individuals aged 50 years and older who have or are at risk for cardiovascular disease [1].
What Other Drugs Work Like Telmisartan?
Several other ARBs are available that function similarly to telmisartan. These include:
* Losartan [2]
* Valsartan [2]
* Olmesartan [2]
* Candesartan [2]
* Irbesartan [2]
* Azilsartan [2]
* Eprosartan [2]
These drugs share the same mechanism of action by blocking the effects of angiotensin II on blood pressure regulation [2].
How Do ARBs Compare to Other Blood Pressure Medications?
ARBs are often compared to another class of blood pressure medications called angiotensin-converting enzyme (ACE) inhibitors. Both ARBs and ACE inhibitors work by targeting the renin-angiotensin-aldosterone system, which regulates blood pressure. However, they do so through slightly different pathways. ACE inhibitors block the production of angiotensin II, while ARBs block its action at the receptor site [3]. While both classes are effective in lowering blood pressure, ARBs may be prescribed for patients who experience side effects, such as a persistent cough, which can be associated with ACE inhibitors [4]. Other classes of blood pressure medications include calcium channel blockers, beta-blockers, and diuretics, each with distinct mechanisms of action [3].
