Beta Blocker and ARB Combination Medications
Introduction to Combination Therapy
- The European Society of Cardiology recommends beta blockers be combined with other major BP-lowering drug classes only when there are compelling indications, such as angina, post-myocardial infarction, heart failure with reduced ejection fraction, or heart rate control needs 1
- Preferred initial combinations explicitly exclude BB + ARB: the guidelines recommend RAS blockers (ACE inhibitor or ARB) combined with either a dihydropyridine calcium channel blocker OR a thiazide diuretic as first-line therapy 1
Available Fixed-Dose Combinations
- Beta blockers + diuretics are available as fixed-dose combinations, including atenolol-chlorthalidone, bisoprolol-hydrochlorothiazide, metoprolol-hydrochlorothiazide, nadolol-bendroflumethiazide, propranolol-hydrochlorothiazide, and timolol-hydrochlorothiazide 2
- ARBs + diuretics are available as fixed-dose combinations, including candesartan-HCTZ, eprosartan-HCTZ, irbesartan-HCTZ, losartan-HCTZ, olmesartan-HCTZ, telmisartan-HCTZ, and valsartan-HCTZ 2
Clinical Scenarios for BB + ARB Use
- Post-myocardial infarction with hypertension: beta blocker for secondary prevention plus ARB for BP control and remodeling prevention 1
- Resistant hypertension: when three or more drug classes are needed, a beta blocker may be added to an existing ARB-based regimen 1
Treatment Algorithms
- For resistant hypertension requiring multiple agents, the recommended escalation is: ARB + CCB + thiazide diuretic, then add spironolactone, then consider adding a beta blocker if not already indicated 1
- If you need to combine an ARB with another agent, first choice is ARB + dihydropyridine calcium channel blocker, second choice is ARB + thiazide diuretic 1, 2
Important Considerations
- The American Heart Association recommends avoiding beta blockers combined with thiazide diuretics unless specifically indicated, as this combination increases risk of new-onset diabetes 3
