Questions and Answers

Which class of drugs reduces systemic vascular resistance (SVR) and blood pressure (BP) by direct arterial vasodilation?

  • Angiotensin II receptor blockers
  • Vasodilators (correct)
  • Angiotensin-converting enzyme (ACE) inhibitors
  • Calcium channel blockers
  • What is the primary mechanism of action of Angiotensin-converting enzyme (ACE) inhibitors?

  • Inhibit movement of Ca2+ across cell membrane
  • Promote dilation of arterioles
