To the Editor: Question 1 of the December 2013 CME test “Can an ARB be given to patients who have had angioedema on an ACE inhibitor?” presents the case of a 73-year-old woman with angioedema thought to be due to her taking enalapril; in addition, she takes hydrochlorothiazide. Her blood pressure is 118/72 mm Hg, and her heart rate is not specified. The question is what the next best step would be to manage her blood pressure medications. The “correct” answer is given as “substitute metoprolol for enalapril in her regimen.”
While this answer is the best choice given, I would take issue with it for two reasons. First, many elderly hypertension patients are overmedicated. With a blood pressure of 118/72 on two medications, it is entirely possible that she may not need to replace the enalapril with any other medication to maintain her pressure below the new JNC 8 threshold of 150/90 for the elderly, or even the 140/90 level specified in other guidelines.
I would recheck her pressure daily on her diuretic alone before adding back a second medication. If she does require a second blood pressure medication, JNC 8 (in agreement with other recent guidelines) recommends adding a calcium channel blocker. Beta-blockers are not recommended by any recent guidelines for first-line or second-line treatment of hypertension for elderly patients without special indications, such as tachyarrhythmias or history of myocardial infarction. No special indications for a beta-blocker were mentioned in this case. Indeed, elderly hypertensive patients often have slow-normal heart rates, or even mild resting bradycardia, which would make the addition of metoprolol contraindicated and potentially dangerous.
