Valsartan vs. Atenolol
See how Valsartan and Atenolol compare on approved uses, dosing, side effects, and cost.
Key Takeaways
Valsartan is an ARB that relaxes blood vessels, while atenolol is a beta-blocker that slows the heart to lower blood pressure.
Valsartan starts at 80 mg once daily and can go up to 320 mg, while atenolol starts at 50 mg once daily and can go up to 200 mg.
Atenolol also treats angina and helps after a heart attack, while valsartan is also approved for heart failure and post-heart-attack survival.
Valsartan vs. Atenolol Drug Summary
Valsartan
Valsartan is an angiotensin II receptor blocker (ARB) that relaxes blood vessels to lower blood pressure. It treats hypertension in adults and children 6 and older, and is also approved for heart failure and to improve survival after a heart attack. It's taken as a tablet once a day, usually starting at 80 mg.
Atenolol
Atenolol is a beta-1 selective blocker that slows the heart rate and reduces the heart's workload to lower blood pressure. It treats hypertension, angina, and is used after a stable heart attack, and is sometimes prescribed off-label for migraine prevention or tremor. It's taken as a tablet once a day, usually starting at 50 mg.

Valsartan vs. Atenolol Indications
Valsartan
Valsartan lowers blood pressure by blocking angiotensin II, a hormone that narrows blood vessels. Beyond hypertension, it's FDA-approved to reduce hospitalization in heart failure and to improve survival after a heart attack. It can be used alone or combined with other blood pressure medications.
Hypertension in adults and children 6+
Heart failure (NYHA class II-IV)
Post-heart attack cardiovascular protection
Can be combined with other BP drugs
Atenolol
Atenolol lowers blood pressure and heart rate by blocking beta-1 receptors in the heart. It's FDA-approved for hypertension, chronic angina, and for stable patients after a heart attack. Doctors also prescribe it off-label for migraine prevention and hand tremor.
Hypertension in adults
Angina pectoris (chest pain)
Stable acute myocardial infarction
Off-label: migraine prevention, tremor
Valsartan vs. Atenolol Pros and Cons
Valsartan
Valsartan avoids the fatigue and breathing risks tied to beta-blockers, making it a common choice for patients with asthma or diabetes. It's also one of the few blood pressure options with an added heart failure and post-heart-attack indication. It has been available as a generic tablet for many years.
Pros
Won't cause the fatigue common with beta-blockers
Safe for patients with asthma or COPD
Also approved for heart failure and post-heart-attack care
Doesn't mask low blood sugar symptoms in diabetes
Cons
Must be stopped if pregnancy occurs
Can raise potassium, needing monitoring in heart failure
Doesn't slow heart rate, so no help for angina
Occasional dizziness, especially with first doses
Atenolol
Atenolol slows the heart, which makes it useful for angina and certain rapid-heart-rate situations that valsartan cannot address. It's been used since 1981 and remains one of the least expensive beta-blockers available. It requires more caution around abrupt discontinuation and certain lung conditions.
Pros
Also treats angina and stable post-heart-attack care
Useful for patients with rapid heart rate or palpitations
Long safety track record since 1981
One of the least expensive beta-blockers available
Cons
Cannot be stopped abruptly without medical guidance
Not recommended for patients with asthma or COPD
Can mask low blood sugar or thyroid symptoms
Common fatigue, cold hands, and low mood
