A 51-year-old male with renal artery stenosis and an elevated BUN and creatinine is newly diagnosed as hypertensive. Which of the following agents should be avoided?
- hydrochlorothiazide-triamterene
- prazosin
- nifedipine
- verapamil
- furosemide
Answer: A
Hydrochlorothiazide-triamterene
This is a potassium-sparing diuretic and should be avoided in anyone with renal disease. ACEI should be avoided as well (but none of these are ACEI's).
