From the Guidelines

Yes, patients with hypertension can be treated concurrently with calcium channel blockers (CCBs) and beta blockers (BBs), but this combination requires careful monitoring due to potential additive effects on heart rate and blood pressure. According to the most recent guidelines, combination therapy is recommended for patients with hypertension, with the potential advantages of fewer side effects and swifter blood pressure control being important for long-term adherence 1. The 2024 ESC guidelines suggest that upfront low-dose combination therapy is recommended in persons with hypertension, with single-pill combinations being preferred 1.

When considering the combination of CCBs and BBs, it's essential to note that this combination can be useful for patients with resistant hypertension, those with comorbid conditions like angina or post-myocardial infarction, or when monotherapy is insufficient to reach blood pressure goals. Common CCBs include amlodipine (5-10 mg daily), diltiazem (120-540 mg daily), and nifedipine (30-90 mg daily), while common BBs include metoprolol (25-200 mg daily), atenolol (25-100 mg daily), and carvedilol (6.25-50 mg twice daily).

Key considerations when using this combination include:

  • Monitoring for potential additive effects on heart rate and blood pressure that could cause bradycardia or hypotension, especially in elderly patients or those with cardiac conduction disorders
  • Regular follow-up appointments to check vital signs, electrolytes, and renal function
  • Being aware of the potential for increased risk of significant bradyarrhythmias and heart failure when combining BBs with nondihydropyridine CCBs (such as diltiazem or verapamil) in patients with symptomatic coronary artery disease and hypertension 2

Overall, the combination of CCBs and BBs can be a valuable treatment option for patients with hypertension, but it's crucial to carefully weigh the benefits and risks and monitor patients closely to minimize potential adverse effects.

From the FDA Drug Label

Concomitant therapy with beta-adrenergic blockers and verapamil may result in additive negative effects on heart rate, atrioventricular conduction and/or cardiac contractility. The combination of sustained-release verapamil and beta-adrenergic blocking agents has not been studied However, there have been reports of excessive bradycardia and AV block, including complete heart block, when the combination has been used for the treatment of hypertension. For hypertensive patients, the risks of combined therapy may outweigh the potential benefits. The combination should be used only with caution and close monitoring Bradycardia and heart block can occur and the left ventricular end diastolic pressure can rise when beta- blockers are administered with verapamil or diltiazem. Patients with pre-existing conduction abnormalities or left ventricular dysfunction are particularly susceptible.

Key Considerations:

  • The combination of calcium channel blockers (CCBs) and beta blockers (BBs) may result in additive negative effects on heart rate and cardiac conduction.
  • The risks of combined therapy may outweigh the potential benefits for hypertensive patients.
  • Close monitoring is necessary when using this combination.

  • Patients with pre-existing conduction abnormalities or left ventricular dysfunction are at higher risk.

    Clinical Decision: Patients with hypertension can be treated concurrently with CCBs and BBs, but with caution and close monitoring due to the potential for additive negative effects on heart rate and cardiac conduction 3, 4.

From the Research

Treatment of Hypertension with Calcium Channel Blockers and Beta Blockers

  • Patients with hypertension can be treated concurrently with calcium channel blockers (CCBs) and beta blockers (BBs) as combination therapy is recommended by guidelines to reach the target blood pressure goal 5.
  • The combination of CCBs and BBs has been shown to be effective in reducing blood pressure and is well tolerated 6.
  • CCBs are one of the most widely studied agents and are generally recommended as first-line therapy alone and in combination therapies, including with BBs 7.

Efficacy and Safety of Combination Therapy

  • Combination therapy with CCBs and BBs has been shown to be more effective and better tolerated than a combination between a BB and hydralazine 6.
  • The new generation BBs, such as nebivolol, have a vasodilator effect, making them a new hope for BB therapy in combination with CCBs 5.
  • Clinical evidence supports the use of combined therapies containing an ACEI with a CCB, but there is limited evidence on the combination of CCBs and BBs specifically 8.

Guidelines and Recommendations

  • Guidelines recommend combining more than one antihypertensive drug to reach the target blood pressure goal, including the combination of angiotensin receptor blockers with either CCBs or BBs 5.
  • The American Family Physician recommends that more than 70% of adults treated for primary hypertension will eventually require at least two antihypertensive agents, either initially as combination therapy or as add-on therapy 9.
  • The European Society of Hypertension recommends the combination of an ACEI with a CCB as one of the recommended combinations in the management of arterial hypertension 8.
