Atenolol, commonly known by its brand name Tenormin, is a beta-blocker medication primarily used to treat high blood pressure (hypertension). It belongs to a class of drugs called beta-adrenergic blocking agents and works by slowing down the heart rate and reducing the force of heart contractions. This action helps lower blood pressure and eases the workload on the heart.
Atenolol has also been found effective in managing other conditions such as angina (chest pain), irregular heartbeats (arrhythmias), and anxiety. In some cases, it is used to prevent heart attacks in people who have a high risk of developing one.

Drug class: Beta-blocker
Atenolol belongs to a class of medications called beta-blockers. Beta-blockers work by blocking the effects of certain hormones, such as adrenaline (epinephrine), on the heart and blood vessels. These hormones normally cause the heart to beat faster and stronger and the blood vessels to narrow, which can increase blood pressure.
By blocking these hormones, beta-blockers slow down the heart rate, reduce the force of heart contractions, and relax the blood vessels. This combination of effects helps lower blood pressure and eases the workload on the heart.
Beta-blockers are commonly used to treat a variety of conditions, including high blood pressure, angina (chest pain), irregular heartbeats (arrhythmias), and anxiety. They may also be used to prevent heart attacks in people who have a high risk of developing one.
Atenolol is a specific type of beta-blocker known as a cardioselective beta-blocker. This means that it primarily affects the heart and has fewer effects on other parts of the body, such as the lungs and airways. This makes it a good choice for people with asthma or other respiratory conditions who need to take a beta-blocker.
Beta-blockers are generally well-tolerated medications, but they can cause side effects in some people. Common side effects of atenolol include fatigue, dizziness, nausea, and diarrhea. Less common side effects include difficulty breathing, wheezing, and hallucinations.
Uses: Hypertension, angina, arrhythmias
Atenolol is primarily used to treat the following conditions:
- Hypertension (high blood pressure): Atenolol is effective in lowering blood pressure in people with hypertension. It works by relaxing the blood vessels and reducing the force of heart contractions, which helps to lower blood pressure.
- Angina (chest pain): Angina is a type of chest pain that occurs when the heart does not receive enough blood and oxygen. Atenolol can help prevent angina attacks by reducing the heart's workload and improving blood flow to the heart.
- Arrhythmias (irregular heartbeats): Atenolol can help control irregular heartbeats by slowing down the heart rate and making the heartbeats more regular. This can help prevent serious complications, such as stroke and heart failure.
In addition to these primary uses, atenolol may also be used to prevent heart attacks in people who have a high risk of developing one. It may also be used to treat anxiety and other conditions, although it is not as commonly used for these purposes.
Atenolol is generally well-tolerated and has a low risk of side effects. However, it is important to take it exactly as prescribed by your doctor and to follow your doctor's instructions for monitoring your blood pressure and heart rate.
If you are taking atenolol for high blood pressure, it is important to make lifestyle changes to help lower your blood pressure, such as eating a healthy diet, exercising regularly, and maintaining a healthy weight. If you are taking atenolol for angina or arrhythmias, it is important to follow your doctor's instructions for managing your condition.
Dosage: Varies depending on condition
The dosage of atenolol varies depending on the condition being treated and the individual patient's response to the medication.
- Hypertension (high blood pressure): The usual starting dose of atenolol for high blood pressure is 50 mg once daily. Your doctor may gradually increase the dose to a maximum of 100 mg once daily or 50 mg twice daily, depending on how well your blood pressure is controlled.
- Angina (chest pain): The usual starting dose of atenolol for angina is 50 mg once daily. Your doctor may gradually increase the dose to a maximum of 100 mg once daily or 50 mg twice daily, depending on how well your angina is controlled.
