Atenolol as a Non-First-Line Treatment for Hypertension

Introduction to Atenolol Limitations

• The American College of Cardiology recommends that beta-blockers, including atenolol, should not be used as first-line agents for hypertension treatment unless the patient has ischemic heart disease or heart failure 1, 2
• Beta-blockers, such as atenolol, are classified as "secondary agents" in current hypertension guidelines, not as first-line treatment 1
• The ACC/AHA 2017 guidelines clearly state that beta-blockers are not recommended as first-line agents unless the patient has ischemic heart disease or heart failure 1, 2

First-Line Treatment Options

• The American College of Cardiology and other guideline societies recommend the following as first-line treatments for hypertension: ACE inhibitors (ACEIs) 4, 5, angiotensin II receptor antagonists (ARBs) 1, 4, calcium channel blockers (CCBs) 1, 5, and thiazide diuretics 1, 4, 5

Specific Indications for Atenolol Use

• Atenolol is indicated for patients with hypertension and concomitant ischemic heart disease 3
• The American Heart Association recommends atenolol for patients with hypertension and previous myocardial infarction 6

Limitations and Considerations

• Atenolol requires twice-daily dosing for optimal blood pressure control, although some studies have used once-daily dosing 1
• In patients with heart failure, recommended beta-blockers are carvedilol, metoprolol succinate, or bisoprolol, not atenolol 7
• For patients with chronic obstructive pulmonary disease (COPD) who require a beta-blocker, cardioselective beta-blockers like atenolol are preferred but should be used with caution 6
• Atenolol is contraindicated in patients with significant bradycardia, second- or third-degree AV block without a pacemaker, or decompensated heart failure 6
