Which of the following drugs blocks the action of angiotensin II at the AT1 receptor?
  1. Bradykinin
  2. Enalapril
  3. Losartan
  4. Prazosin
Explanation
Answer − C − The drug that blocks the action of angiotensin II at the AT1 receptor is losartan. Losartan and several other angiotensin receptor blockers (ARBs) block the action of angiotensin II at its primary cardiovascular target, the AT1 receptor, thus not allowing angiotensin II, a powerful vasoconstrictor, to form.
