Amlodipine vs. Metoprolol

See how Amlodipine and Metoprolol compare on approved uses, dosing, side effects, and cost.

Key Takeaways

  • Amlodipine relaxes blood vessels as a calcium channel blocker, while metoprolol slows the heart as a beta-blocker, so doctors sometimes combine them for harder-to-control blood pressure.

  • Amlodipine is usually started and kept at one steady dose, while metoprolol needs several weeks of gradual increases before reaching a maintenance dose.

  • Both treat high blood pressure and angina, but metoprolol also treats heart failure and cannot be stopped abruptly without tapering the dose.

Amlodipine vs. Metoprolol Drug Summary

Amlodipine

Amlodipine is a dihydropyridine calcium channel blocker that widens blood vessels to lower blood pressure and ease angina-related chest pain. It is taken as a single oral tablet once a day, typically starting at 2.5 mg and adjusted up to 10 mg based on response.

Metoprolol

Metoprolol is a beta-1 selective blocker that slows the heart rate and reduces the force of each heartbeat to lower blood pressure. It comes as an extended-release tablet taken once daily, starting low and increasing over several weeks to reach a maintenance dose.

Amlodipine vs. Metoprolol Indications

Amlodipine

Amlodipine is FDA-approved for high blood pressure and several types of chest pain, including chronic stable angina and vasospastic (Prinzmetal's) angina caused by artery spasm. It's also approved for coronary artery disease to help reduce the risk of hospitalization and procedures.

  • Hypertension

  • Chronic stable angina

  • Vasospastic (Prinzmetal's) angina

  • Coronary artery disease

Metoprolol

Metoprolol is FDA-approved for high blood pressure, angina pectoris, and stable heart failure across NYHA classes II through IV. Doctors also prescribe it off-label for atrial fibrillation rate control, migraine prevention, and essential tremor.

  • Hypertension

  • Angina pectoris

  • Heart failure (NYHA class II-IV)

  • Atrial fibrillation rate control (off-label)

Amlodipine vs. Metoprolol Pros and Cons

Amlodipine

Amlodipine's long half-life means one missed dose rarely causes a big blood pressure swing, and it needs no dose adjustment for kidney function. Its main drawback is fluid buildup in the legs, which is dose-related and more common in women.

Pros

  • Once-daily dosing with no titration required for most patients

  • No kidney dose adjustment needed

  • Approved for vasospastic (Prinzmetal's) angina

  • Long half-life smooths out missed or late doses

Cons

  • Leg and ankle swelling in up to 10.8% of patients

  • Can cause a reflex increase in heart rate (palpitations)

  • Not indicated for heart failure or arrhythmia control

  • Caution needed with severe aortic stenosis

Metoprolol

Metoprolol lowers heart rate and eases the heart's workload, making it useful for heart failure and rhythm control in addition to blood pressure. It requires a multi-week titration schedule and must be tapered rather than stopped suddenly.

Pros

  • Also approved for stable heart failure (NYHA II-IV)

  • Useful off-label for migraine and tremor

  • One of the lowest-cost generic beta-blockers

  • Reduces heart rate, helpful for arrhythmia control

Cons

  • Requires several weeks of gradual dose increases

  • Cannot be stopped abruptly; needs a 1-2 week taper

  • Contraindicated in bradycardia and certain heart blocks

  • Higher rates of hypotension and fatigue than amlodipine
