How can NSAIDs affect blood pressure control?

• A. They can cause vasodilation
• B. They can induce bradycardia
• C. They can cause sodium and fluid retention
• D. They have no effect on blood pressure

Answer: (C)

Nonsteroidal anti-inflammatory drugs (NSAIDs) are known to impact blood pressure control primarily due to their effects on sodium and fluid retention. When NSAIDs are used, they inhibit the enzyme cyclooxygenase (COX), which plays a critical role in the production of prostaglandins. Prostaglandins are involved in maintaining renal blood flow and regulating sodium excretion. By decreasing prostaglandin synthesis, NSAIDs can lead to increased sodium reabsorption in the kidneys. This sodium retention can subsequently lead to fluid retention, which increases blood volume and may elevate blood pressure. This effect is particularly significant in individuals who are already predisposed to hypertension or who are taking certain antihypertensive medications. The other choices provided do not accurately convey the mechanisms by which NSAIDs impact blood pressure. Vasodilation and bradycardia are not typical effects associated with NSAIDs, and stating that NSAIDs have no effect on blood pressure ignores their well-documented potential to influence blood pressure through fluid and sodium retention. Therefore, the impact of NSAIDs on blood pressure primarily revolves around their ability to cause sodium and fluid retention, underlining the importance of monitoring blood pressure in patients taking these medications, especially those with existing hypertension.
