Which interaction is common between NSAIDs and antihypertensive therapy?

• A. NSAIDs can reduce the antihypertensive effect and worsen renal function; monitor kidney function and blood pressure.
• B. NSAIDs have no interaction.
• C. NSAIDs increase antihypertensive effect.
• D. NSAIDs improve kidney function.

Answer: (A)

Nonsteroidal anti-inflammatory drugs can interfere with how antihypertensive medicines work by affecting kidney function and salt-water balance. NSAIDs inhibit prostaglandin synthesis, which helps keep blood flow to the kidneys when blood pressure or perfusion is challenged. By reducing prostaglandins, NSAIDs can cause afferent arteriolar constriction and a drop in glomerular filtration rate, increasing the risk of kidney injury, especially when someone is on antihypertensive therapy such as ACE inhibitors, ARBs, or diuretics. This combination can blunt the blood-pressure–lowering effect and worsen renal function, so it’s important to monitor kidney function and blood pressure when NSAIDs are used concurrently. If possible, use the lowest effective dose for the shortest duration and consider alternatives like acetaminophen, especially in patients with known kidney issues or those who are volume-depleted or elderly.
