Final answer:
Hydralazine works by causing vasodilation of the arterioles, which reduces blood pressure by decreasing resistance to blood flow. It does not increase sodium reabsorption through the production of angiotensin II.
Step-by-step explanation:
Hydralazine works on the arterioles by causing vasodilation, which is the widening of the blood vessels. By dilating the arterioles, hydralazine reduces the resistance to blood flow and lowers blood pressure. This is achieved by relaxing the smooth muscle in the walls of the arterioles, resulting in an increase in the diameter of the blood vessels.
Since hydralazine works on the arterioles, it does not have the risk for increasing sodium reabsorption through the production of angiotensin II. Angiotensin II is a hormone involved in regulating blood pressure and sodium balance in the body.
Therefore, hydralazine does not lead to an increased risk of sodium reabsorption and subsequently, the risk of increased blood pressure.
