Summary
Adding an ACE inhibitor to a regimen already containing the angiotensin receptor blocker valsartan produces dual renin-angiotensin system blockade. This raises the risk of symptomatic hypotension, hyperkalemia and acute kidney injury without a meaningful cardiovascular benefit in most patients.
What this interaction means in plain words
Amlodipine-hydrochlorothiazide-valsartan and Benazepril can interact in a way that may be serious. Using them together is sometimes necessary, but it needs a deliberate decision by the prescriber, a plan for monitoring, and clear advice on the warning signs to watch for.
Amlodipine-hydrochlorothiazide-valsartan belongs to Cardiovascular; Benazepril belongs to Cardiovascular.
Why it happens
Additive pharmacodynamic inhibition of the renin-angiotensin-aldosterone system at two different points, reducing glomerular filtration pressure and aldosterone-mediated potassium excretion.
What to do
Avoid the combination and use a single renin-angiotensin agent. If it is unavoidable, monitor blood pressure, serum potassium and creatinine closely.
What to ask your pharmacist
- Does the benefit of taking both outweigh the risk in my case?
- Do I need any blood test, ECG or other check while on both?
- What early warning signs should I watch for, and what should I do if they appear?
