Published May 07, 2026

Atenolol belongs to a class of drugs known as beta blockers. It works by blocking the action of certain natural chemicals in your body, such as epinephrine, on the heart and blood vessels. This effect lowers the heart rate, blood pressure, and strain on the heart.

Is Tenormin a ACE inhibitor?

Specifically, Tenormin is a beta-blocker and Zestril is an angiotensin converting enzyme (ACE) inhibitor.

Is Tenormin and atenolol the same?

Atenolol is available as the brand-name drug Tenormin. It’s also available as a generic drug.

What classification is atenolol?

Atenolol is in a class of medications called beta blockers. It works by relaxing blood vessels and slowing heart rate to improve blood flow and decrease blood pressure.

What drug class includes beta blockers?

What are beta blockers and how do they work? Beta blockers, also known as beta-adrenergic blocking agents, are a class of drugs that works by blocking the neurotransmitters norepinephrine and epinephrine from binding to receptors.

Why is Tenormin prescribed?

Atenolol is used with or without other medications to treat high blood pressure (hypertension). Lowering high blood pressure helps prevent strokes, heart attacks, and kidney problems. This medication is also used to treat chest pain (angina) and to improve survival after a heart attack.

Is the drug gabapentin?

Gabapentin is used with other medications to prevent and control seizures. It is also used to relieve nerve pain following shingles (a painful rash due to herpes zoster infection) in adults. Gabapentin is known as an anticonvulsant or antiepileptic drug.

Which is better atenolol or amlodipine?

Compared to atenolol, amlodipine therapy decreased systolic blood pressure more effectively in LH and DOCA rats, but less effectively in SHR and 2K1C rats. The combination of atenolol and amlodipine (10 + 1 mg/kg) produced the largest effect on blood pressure reduction in all four types of hypertensive rats.

Is atenolol an immunosuppressant?

Why was atenolol taken off the market?

Atenolol is in a shortage, because an active ingredient used to manufacture the drug is in low supply. This, along with high demand for the medication, is why it is in shortage. The drug was also recently added to the Walmart $4 generic list.

Which is better atenolol or metoprolol?

Metoprolol showed a more significant reduction in risk of cardiovascular mortality as compared to atenolol. Metoprolol also showed a decreased trend for all-cause mortality and coronary heart disease. When evaluated for a decrease in risk of stroke, metoprolol proved to be superior to atenolol as well.

Is lisinopril a beta blocker or ACE inhibitor?

Lisinopril belongs to a class of medications called ACE inhibitors. ACE is short for angiotensin-converting enzymes. Lisinopril is considered an antihypertensive drug. In general, antihypertensive drugs are used as a treatment for high blood pressure.

Why is atenolol not used in heart failure?

Atenolol has been described as providing a “pseudo antihypertensive effect” because it lowers peripheral arterial pressure but not central aortic pressure and therefore may not reduce the pressure to which the heart and brain are exposed.

What class of drug is Acebutolol?

Acebutolol is in a class of medications called beta blockers. It works by relaxing blood vessels and slowing heart rate to improve blood flow and decrease blood pressure.

What beta-blockers are Cardioselective?

The cardio-selective beta-blockers include atenolol, betaxolol, bisoprolol, esmolol, acebutolol, metoprolol, and nebivolol [1].

What is the most commonly prescribed beta-blocker?

As seen in figure 1, the most commonly prescribed beta-blocker medications are metoprolol succinate and metoprolol tartrate. While both drugs are used to treat heart-related issues, their applications are very different.

Why is gabapentin bad?

Some of the severe side effects include trouble breathing and allergic reactions. People who start to use gabapentin should pay attention to shifts in mood or emotions. For example, a person who experiences increased anxiety, anger, or panic attacks should contact a doctor right away.

What drug class is gabapentin?

Gabapentin is in a class of medications called anticonvulsants. Gabapentin treats seizures by decreasing abnormal excitement in the brain. Gabapentin relieves the pain of PHN by changing the way the body senses pain.

Is gabapentin like Xanax?

Similarities of Gabapentin and Xanax Gabapentin and Xanax both work for treating anxiety by affecting the chemical signal of GABA in brain cells. Both medications start working right away and are relatively safe when they are used correctly.

Is Tenormin a controlled substance?

Tenormin 100 mg is not a controlled substance under the Controlled Substances Act (CSA).

Is Tenormin a selective beta blocker?

Beta-1 selective blockers are a subclass of beta blockers that are commonly used to treat high blood pressure. Drugs in this class include atenolol (Tenormin), metoprolol (Lopressor), nebivolol (Bystolic) and bisoprolol (Zebeta, Monocor).

Is Tenormin a good drug?

Atenolol (Tenormin) is a good medication for controlling chest pain (angina). It can also lower the chance of death if taken after a heart attack. Though atenolol (Tenormin) can be taken for blood pressure, it is not preferred and is typically only used if other blood pressure medications are not working.

Is Tenormin still available?

AstraZeneca will continue to manufacture and supply Inderal, Tenormin, Tenoretic, Zestril and Zestoretic to Atnahs during a transition period. Atnahs will make an upfront payment of $350m to AstraZeneca. AstraZeneca may also receive future sales-contingent payments of up to $40m between 2020 and 2022.

Does atenolol cause weight gain?

Yes. Weight gain can occur as a side effect of some beta blockers. The average weight gain is about 2.6 pounds (1.2 kilograms). Weight gain is more likely with older beta blockers, such as atenolol (Tenormin) and metoprolol (Lopressor, Toprol-XL).

Is atenolol the same as propranolol?

Inderal (Propranolol) Lowers blood pressure and controls heart rate. Tenormin (atenolol) is good for controlling chest pain and treating a heart attack. It has fewer side effects than other beta blockers.

Is Tenormin a calcium channel blocker?

Tenormin is also used for management of heart attack (acute myocardial infarction) and occasionally for thyroid storm management. Norvasc (amlodipine) and Tenormin belong to different drug classes. Norvasc is a calcium channel blocker (CCB) and Tenormin is a beta-blocker.

Is there an alternative to amlodipine?

There are several other calcium channel blockers that work in the same way as amlodipine. They include nifedipine, felodipine, lacidipine and lercanidipine. There are other calcium channel blockers, such as diltiazem and verapamil, that have other effects on the heart.

Does amlodipine lower systolic or diastolic?

In whole-body cold air exposure, amlodipine slightly decreases the levels of both systolic and diastolic pressures, but has no effect on the cold-induced rise of blood pressure.

What is a good replacement for atenolol?

Atenolol, on the other hand, only has one release form. All three are available as generic and brand-name medications: Metoprolol immediate release: Lopressor. Metoprolol extended release (ER): Toprol XL.

Can atenolol cause memory loss?

Beta-blockers such as atenolol typically do not cause memory loss or decline in cognitive function, although it is certainly possible that you might be having a reaction along these lines (or possibly as a result of one of your other medications).

Should I avoid certain foods while taking atenolol?

You may take atenolol with or without food, but take it the same way every time. Avoid consumption of large amounts of orange juice to prevent any changes in your atenolol levels. Orange juice could decrease the effectiveness of atenolol.
