Lisinopril vs. Atenolol
See how Lisinopril and Atenolol compare on approved uses, dosing, side effects, and cost.
Key Takeaways
Lisinopril is an ACE inhibitor and atenolol is a beta-blocker, so they lower blood pressure through different mechanisms and are sometimes combined rather than compared as strict alternatives.
Lisinopril is usually tried first for high blood pressure, while beta-blockers like atenolol are now reserved mainly for angina, certain heart rhythms, or recovery after a heart attack.
Both are inexpensive generics, but lisinopril often causes a dry cough while atenolol commonly causes fatigue, cold hands and feet, and can worsen asthma.
Lisinopril vs. Atenolol Drug Summary
Lisinopril
Lisinopril is an ACE inhibitor that relaxes blood vessels by blocking a hormone that narrows them. It treats high blood pressure, helps manage heart failure, and improves survival after a heart attack. It is taken as one tablet by mouth once a day, usually starting at 10 mg.
Atenolol
Atenolol is a beta-1 selective beta-blocker that slows the heart rate and reduces how hard the heart pumps to lower blood pressure. It treats high blood pressure, chronic angina, and is used in stable patients after a heart attack. It is taken as one tablet by mouth once a day, usually starting at 50 mg.

Lisinopril vs. Atenolol Indications
Lisinopril
Lisinopril is FDA-approved for high blood pressure, as an add-on therapy for heart failure, and to improve survival in the days after a heart attack. Doctors also prescribe it off-label to help protect kidney function in people with diabetes.
Hypertension (approved)
Heart failure, add-on therapy (approved)
Acute myocardial infarction, started early (approved)
Off-label: diabetic kidney protection
Atenolol
Atenolol is FDA-approved for high blood pressure, long-term management of angina, and for stable patients recovering from a heart attack. Doctors also prescribe it off-label for migraine prevention and to control hand tremors.
Hypertension (approved)
Angina pectoris, chronic chest pain (approved)
Acute myocardial infarction, stable patients (approved)
Off-label: migraine prevention and tremor
Lisinopril vs. Atenolol Pros and Cons
Lisinopril
Lisinopril is a low-cost, once-daily generic with strong evidence for protecting the heart and kidneys, especially in people with diabetes or heart failure. It does not interfere with the body's warning signs of low blood sugar, an advantage for people who also have diabetes.
Pros
Only needs to be taken once a day
Does not mask low blood sugar warning signs
Shown to slow kidney damage in diabetes
Improves survival when started after a heart attack
Cons
Causes a dry, persistent cough in some people
Rare but serious swelling reaction (angioedema)
Not safe to use during pregnancy
Can raise potassium levels, needs monitoring
Atenolol
Atenolol works well for people who have both high blood pressure and angina, since it reduces how hard the heart has to work. It must not be stopped suddenly and needs caution in people with asthma or lung disease. It is no longer first-choice therapy for straightforward high blood pressure.
Pros
Also treats angina, not just blood pressure
May help prevent migraines (off-label use)
Slows heart rate, useful for certain arrhythmias
Long safety record, available since 1981
Cons
Cannot be stopped abruptly without a doctor
Can mask low blood sugar warning signs
Often causes fatigue, cold hands and feet
No longer first-line for straightforward hypertension
