Quizplus · Accepted Answer

ACE inhibitors work by blocking the enzyme that converts angiotensin I to angiotensin II, a potent vasoconstrictor. By blocking the formation of angiotensin II, ACE inhibitors cause blood vessels to relax which results in a decrease in blood pressure. CCBs (choice B) also work by relaxing blood vessels, but they do so by blocking the entry of calcium into muscle cells in the vessel walls. TDN (choice C) is not a drug name or class. HMG-CoA reductase inhibitors (choice D) lower cholesterol levels by inhibiting the enzyme responsible for cholesterol synthesis in the liver and do not directly affect blood vessel tone.
