Key Takeaways

  • Metoprolol succinate is FDA-approved for certain patients with stable, symptomatic heart failure, while atenolol is not. The better choice depends on the patient's heart condition, other health conditions, and response to treatment.

  • Both drugs are available as generic beta-blockers. Dosing depends on the condition being treated and the patient's response. Either drug can slow the heart rate and lower blood pressure, and neither should be stopped suddenly without medical guidance.

  • Atenolol is cleared by the kidneys and needs dose adjustment in renal impairment, while metoprolol is metabolized by the liver.

Metoprolol vs. Atenolol Drug Summary

Metoprolol

Metoprolol succinate is a beta-1 selective beta-blocker used to treat high blood pressure, angina, and stable heart failure. It comes as an extended-release tablet taken once a day, with the dose slowly increased over several weeks.

Atenolol

Atenolol is a beta-1 selective beta-blocker used to treat high blood pressure, angina, and stable patients recovering from a heart attack. It is taken as a standard oral tablet once daily, usually starting at a fixed dose with one step up if needed.

Metoprolol vs. Atenolol Side Effects

tiredness (about 10%)

Atenolol

Metoprolol vs. Atenolol Indications

Metoprolol

Metoprolol is FDA-approved for hypertension, angina, and stable heart failure across NYHA classes II through IV. It is also used off-label for atrial fibrillation rate control, migraine prevention, and essential tremor.

  • Hypertension

  • Angina pectoris

  • Heart failure (NYHA Class II-IV)

  • Off-label: atrial fibrillation rate control

  • Off-label: migraine prevention, essential tremor

Atenolol

Atenolol is FDA-approved for hypertension, angina, and use in hemodynamically stable patients after a heart attack. It is also used off-label for migraine prevention and tremor.

  • Hypertension

  • Angina pectoris

  • Acute myocardial infarction (stable patients)

  • Off-label: migraine prevention

  • Off-label: tremor

Metoprolol vs. Atenolol Pros and Cons

Metoprolol

Metoprolol's extended-release formulation and FDA approval for heart failure make it a versatile option for patients with overlapping cardiac conditions. It requires a multi-step titration schedule before reaching a maintenance dose.

Pros

  • FDA-approved for heart failure, not just blood pressure

  • Once-daily extended-release form smooths out blood levels

  • Metabolized by the liver, no renal dose adjustment needed

Cons

  • Requires several titration steps to reach maintenance dose

  • Not approved for acute decompensated heart failure or cardiogenic shock

  • Higher maximum maintenance dose may mean more pills at higher strengths

Atenolol

Atenolol offers a simpler dosing path with fewer titration steps, and it carries a specific approval for use after a heart attack. It is not approved for heart failure and needs dose adjustment in kidney disease.

Pros

  • Simpler dosing schedule with just one step-up

  • Specifically approved for use after a heart attack

  • Longer track record, approved by the FDA since 1981

Cons

  • Not approved for heart failure

  • Requires dose adjustment in patients with kidney impairment

  • Higher rate of fatigue reported than metoprolol's tiredness rate
