Zebeta and Coreg are the Same Class of Drugs (Beta-Blockers)

Zebeta and Coreg are two medications that belong to the same class of drugs called beta-blockers. Although they share a similar mechanism of action, there are some key differences that we will discuss below. 

What Are Beta-Blockers?

Beta-blockers are a class of medications prescribed for a wide variety of conditions. They are most commonly used to treat cardiovascular diseases due to their effects on the heart by lowering blood pressure and heart rate. The generic drug names for the majority of beta-blockers typically end with “-olol.” 

How Do Beta-Blockers Work?

Beta-blockers work on specific receptors in the body called beta receptors. These receptors are found throughout the body but are most notably in the heart, where they predominantly work. Each beta blocker acts on a different assortment of receptors, including alpha and beta receptors, making each medication unique.  

There are two different types of beta-receptors, beta-1 and beta-2, which are found throughout the body and in the heart and in blood vessels. 

Beta-1 receptors are primarily found within the heart and kidneys, which are responsible for maintaining our blood pressure and heart rate. When beta-1 receptors are activated, epinephrine is released and signals for the heart to pump faster and harder, causing an increase in blood pressure and heart rate. 

Beta-2 receptors are located in the smooth muscle of blood vessels, the nervous system and the respiratory system to also maintain cardiovascular and respiratory balance. When beta-2 receptors are activated, epinephrine signals for changes in vascular tone throughout the body, including the lungs, and increases the workload of the heart. 

Beta-blockers act by binding to the receptors to block the effects of a hormone called epinephrine, also known as adrenaline, and therefore slow signaling down. In doing so, the medication primarily works to slow down the heart’s rate and reduce blood pressure, among other actions. 

Zebeta is a selective beta-1 receptor antagonist, while Coreg is a beta-1 and beta-2 receptor antagonist. The term antagonist is used to describe the blocking mechanism on the receptor, as described above. 

Zebeta and Coreg Can Both Treat the Physical Symptoms of Anxiety

Generalized anxiety disorder is one of the most commonly diagnosed psychiatric conditions known to cause both psychological and physical symptoms. Anxiety is defined as uncontrollable or unwanted thoughts or fears that are not proportional to the given situation. This can appear in many forms, such as panic attacks, social anxiety, PTSD, or generalized anxiety, to name a few. 

Some of the most common physical symptoms associated with anxiety include: 

• Increased or irregular heart rate 
• Increased rate of breathing 
• Sweating or hot flashes 
• Tremor 
• Feeling light-headed or dizzy 
• Feeling restless or unable to sit still 
• Headaches 
• Uneasy feeling in your stomach 

What Else Does Zebeta Treat?

Zebeta is most commonly prescribed for cardiovascular conditions but is only FDA-approved for the use of high blood pressure or hypertension. It can be used by itself or in combination with other antihypertensive medications. 

Off-label Uses for Zebeta  

The term “off-label” is used to describe a medication that has not been FDA-approved. FDA approval requires a large amount of time, funding and resources, which acts as a major barrier to receiving FDA approval. Although a medication is used off-label, this does not mean it is not effective at treating the specific condition. 

Some common off-label uses for Zebeta include: 

• Physical symptoms of anxiety disorders
• Chest pain
• Atrial fibrillation or flutter 
• Heart failure with reduced ejection fraction
• Ventricular arrhythmias 
• Prevention of heart attacks or stroke 
• Migraine headache prevention 

What Else Does Coreg Treat?

Coreg is most commonly used to treat cardiovascular conditions and is FDA-approved to treat: 

• High blood pressure 
• Mild to severe chronic heart failure 
• Left ventricular dysfunction after a heart attack

Off-label Uses for Coreg 

As previously mentioned, the term “off-label” simply means that the medication is not FDA-approved for the specific use, and this does not mean it is not effective at treating the given condition. 

Some common off-label uses for Coreg include: 

• Anxiety disorders 
• Heart rate control in those with atrial fibrillation
• Chest pain 
• Portal hypertension in people with cirrhosis or liver damage
• Prevention of bleeding in those with esophageal varices or abnormal vein formation due to liver damage

Beta Blocker Drug Warnings

It is important to take your medication as prescribed by your healthcare provider. If you are considering stopping the medication, notify your provider, as you will likely need to be tapered off. If you discontinue the medication abruptly, you are more likely to experience adverse effects, such as dangerous increases in blood pressure. 

Pregnancy and Breastfeeding on Beta-Blockers

While beta-blockers are typically considered relatively safe for use during pregnancy and breastfeeding, there should always be caution while using beta-blockers in pregnancy. Beta-blockers are considered to be a first-line medication for hypertension during pregnancy but have been shown to cause low heart rate and low blood glucose levels in the fetus. 

It is important to monitor fetal growth throughout pregnancy and 48 hours after delivery when taking beta-blockers. Some of the most common findings include low heart rate, low blood sugar, and depressed respiratory drive in the newborn. 

Treating maternal hypertension typically outweighs the adverse effects, as chronic high blood pressure throughout birth can be unhealthy. If the medication is used solely for the purpose of reducing physical symptoms of anxiety during pregnancy, discuss this with your healthcare provider, as a different medication may be a better option for you.

Coreg and Zebeta Frequently Asked Questions

We went over a lot of information and understand that navigating through your different treatment options can be challenging. Below we have listed some of the most commonly asked questions about Coreg and Zebeta.

What is Coreg?

Coreg is a beta-1 and beta-2 receptor blocker that can help treat various cardiovascular conditions, most notably hypertension and chronic heart failure. Coreg is also known to be effective in the treatment of the physical symptoms of anxiety. 

What is Zebeta?

Similar to Coreg, Zebeta is another beta blocker medication that is primarily used for the treatment of high blood pressure but is also effective in the treatment of the physical symptoms associated with anxiety. Zebeta is a selective beta-1 receptor antagonist. 

Are Coreg, Zebeta, and other Beta-Blockers the same drug?

Although Coreg and Zebeta belong to the same class of medications, called beta-blockers, they are not the same drug. They share a similar mechanism of action, but they have key differences. 

What’s better for anxiety? Coreg or Zebeta?

Overall, beta-blockers are not considered a first-line treatment for anxiety, as there are other medications that are more effective and are FDA-approved for the treatment of anxiety. 

When comparing Coreg and Zebeta, they are typically seen as equally effective with regard to treating anxiety. Of note, the most effective beta blocker for anxiety is propranolol or Inderal. 

Can I drink alcohol on Coreg or Zebeta?

It is generally recommended to avoid drinking alcohol while taking a beta-blocker due to changes in blood pressure. Alcohol consumption while taking a beta-blocker can cause your blood pressure to rise and fall, which increases the risk of fainting, falling or other injuries. 

Does it matter what time of day I take Coreg or Zebeta?

It is important to take the medication as prescribed by your healthcare provider, including the dosage and the time of day. Typically, Coreg is taken twice a day, and Zebeta is taken once daily. 

The medication is usually taken during the day when you are more likely to have symptoms, but your prescribing provider will instruct you on when to take your medication specifically.
