What is telmisartan, and how does it work (mechanism of action)?
Telmisartan is a member of a family of drugs called angiotensin receptor blockers (ARBs), which includes losartan (Cozaar), valsartan (Diovan), irbesartan (Avapro), and candesartan (Atacand). Angiotensin, formed in the blood by the action of angiotensin converting enzyme (ACE), is a powerful chemical that attaches to angiotensin receptors found in many tissues but primarily on muscle cells of blood vessels. Angiotensin's attachment to the receptors causes muscle cells to shorten and narrow the blood vessels (vasoconstrict), which leads to an increase in blood pressure (hypertension). Telmisartan blocks the angiotensin receptor. By blocking the action of angiotensin, telmisartan widens blood vessels (vasodilate) and reduces blood pressure. Telmisartan was approved by the FDA in November 2000.
