What is the primary mechanism of action for ACE inhibitors?

  1. Prevent the breakdown of bradykinin and substance P

  2. Increase the synthesis of angiotensin II

  3. Stimulate aldosterone secretion

  4. Enhance vasodilation directly

The correct answer is: Prevent the breakdown of bradykinin and substance P

ACE inhibitors work by preventing the enzyme ACE (angiotensin converting enzyme) from breaking down bradykinin and substance P. This allows these substances to build up in the body and promote vasodilation, leading to decreased blood pressure. Option B is incorrect because ACE inhibitors actually decrease the synthesis of angiotensin II, not increase it. Option C is incorrect because ACE inhibitors actually decrease aldosterone secretion. Lastly, option D is incorrect because ACE inhibitors do not directly enhance vasodilation, they do so indirectly by increasing the levels of bradykinin and substance P.
