What are beta blockers, and what are they used for?
Beta blockers, also known as beta-adrenergic blocking agents, are drugs that block norepinephrine and epinephrine (adrenaline) from binding to beta receptors on nerves.
Norepinephrine and epinephrine are produced by nerves throughout the body as well as by the adrenal gland. They serve as neurotransmitters (chemicals that nerves use to communicate with one another) that may be active locally where they are produced, or elsewhere in the body, when they are released into the blood. There are both alpha and beta receptors in the body.
3 types of beta receptors
There are three types of beta receptors and they control several different functions based on their location in the body.
- beta-1 (β1) receptors are located in the heart, eye, and kidneys.
- beta (β2) receptors are found in the lungs, gastrointestinal tract, liver, uterus, blood vessels, and skeletal muscle.
- beta (β3) receptors are located in fat cells.
Beta blockers primarily block β1 and β2 receptors and thereby the effects of norepinephrine and epinephrine. By blocking the effects of norepinephrine and epinephrine, beta blockers reduce heart rate; reduce blood pressure by dilating blood vessels; and may constrict air passages by stimulating the muscles that surround the air passages to contract considered an adverse side effect).
Beta blockers are used for treating:
- Abnormal heart rhythms
- High blood pressure
- Heart failure
- Angina (heart pain)
- Tremor
- Pheochromocytoma
- Prevention of migraines
- Hypertrophic subaortic stenosis
- They also have been found to prevent further heart attacks and death after a heart attack.
- Other uses include the treatment of hyperthyroidism, akathisia (restlessness or inability to sit still), panic disorder, anxiety, and aggressive behavior.
- Some beta blockers reduce the production of aqueous humor in the eye and therefore are used for reducing pressure in the eye caused by glaucoma.
What are the side effects of beta blockers?
Beta blockers may cause:
Other important side effects include:
- Rash
- Blurred vision
- Disorientation
- Insomnia
- Hair loss
- Weakness
- Muscle cramps
- Fatigue
As an extension of their beneficial effect, they slow heart rate and reduce blood pressure, but they may cause adverse effects such as heart failure or heart block in patients with heart problems.
Beta blockers should not be withdrawn suddenly because sudden withdrawal may worsen angina (chest pain) and cause heart attacks, serious abnormal heart rhythms, or sudden death.
- Central nervous system effects of beta blockers include:
- Headache
- Depression
- Confusion
- Dizziness
- Nightmares
- Hallucinations
Beta blockers that block β2 receptors may cause shortness of breath in asthmatics.
As with other drugs used for treating high blood pressure, sexual dysfunction may occur.
Beta blockers may cause low or high blood glucose and mask the symptoms of low blood glucose (hypoglycemia) in people with diabetes.
Other serious side effects of beta-blockers include:
List of examples of brand and generic names for beta blockers?
- acebutolol (Sectral)
- atenolol (Tenormin)
- betaxolol (Kerlone)
- betaxolol (Betoptic S)
- bisoprolol fumarate (Zebeta)
- carteolol (Cartrol, discontinued)
- carvedilol (Coreg)
- esmolol (Brevibloc)
- labetalol (Trandate [Normodyne - discontinued])
- metoprolol (Lopressor, Toprol XL)
- nadolol (Corgard)
- nebivolol (Bystolic)
- penbutolol (Levatol)
- pindolol (Visken, discontinued)
- propranolol (Hemangeol, Inderal LA, Inderal XL, InnoPran XL)

- timolol (Blocadren, discontinued)
- timolol ophthalmic solution (Timoptic, Betimol, Istalol)
QUESTION
Salt and sodium are the same. See AnswerWhat are the differences amongst the beta blockers available?
Beta blockers differ in the type of beta receptors they block and, therefore, their effects.
- Non-selective beta blockers, for example, propranolol (Inderal), block β1 and β2 receptors and, therefore, affect the heart, blood vessels, and air passages.
- Selective beta blockers, for example, metoprolol (Lopressor, Toprol XL) primarily block β1 receptors and, therefore, mostly affect the heart and do not affect air passages.
- Some beta blockers, for example, pindolol (Visken) have intrinsic sympathomimetic activity (ISA), which means they mimic the effects of epinephrine and norepinephrine and can cause an increase in blood pressure and heart rate. Beta blockers with ISA have smaller effects on heart rate than agents that do not have ISA.
- Labetalol (Normodyne, Trandate) and carvedilol (Coreg) block beta and alpha-1 receptors. Blocking alpha receptors adds to the blood vessel dilating effect of labetalol and carvedilol.
What drugs interact with beta blockers?
- Combining propranolol (Inderal) or pindolol (Visken) with thioridazine (Mellaril) or chlorpromazine (Thorazine) may result in low blood pressure (hypotension) and abnormal heart rhythms because the drugs interfere with each other's elimination and result in increased levels of the drugs.
- Dangerous elevations in blood pressure may occur when clonidine (Catapres) is combined with a beta blocker, or when clonidine or beta blocker is discontinued after their concurrent use. Blood pressure should be closely monitored after initiation or discontinuation of clonidine or a beta blocker when they have been used together.
- Phenobarbital and similar agents may increase the breakdown and reduce blood levels of propanolol (Inderal) or metoprolol (Lopressor, Toprol XL). This may reduce effectiveness of the beta blocker.
- Aspirin and other nonsteroidal anti-inflammatory drugs (NSAIDs) (for example, ibuprofen) may counteract the blood pressure reducing effects of beta blockers by reducing the effects of prostaglandins, which play a role in control of blood pressure.
- Beta blockers may prolong hypoglycemia (low blood sugar) and mask symptoms of hypoglycemia in diabetics who are taking insulin or other diabetic medications.

Heart Anatomy: Diagram, Blood Flow and FunctionsThe heart is a very important organ in the body. It is responsible for continuously pumping oxygen and nutrient-rich blood throughout your body to sustain life. It is a fist-sized muscle that beats (expands and contracts) 100,000 times per day, pumping a total of five or six quarts of blood each minute, or about 2,000 gallons per day.
-
High Blood Pressure (Hypertension)High blood pressure (hypertension) occurs due to the tightening or stiffness of very small arteries called arterioles. As a result, the heart pumps harder through the stiff or narrow arterioles, leading to elevated pressure inside the vessels. Hypertension is known as 'the silent killer' because it often goes unnoticed and may cause serious complications such as kidney diseases, heart diseases, heart failure, and stroke.

-
Peyronie's Disease (Curvature of the Penis)Peyronie's disease or curvature of the penis (Peyronie disease) is a condition in which scar tissue develops inside the penis. This scar tissue causes the penis to develop an abnormal curvature in the scarred area. At this time, there is no known cause of Peyronie's disease. Symptoms of Peyronie's disease include pain during intercourse or ejaculation, erectile dysfunction (ED, impotence), the inability to have sexual intercourse, anxiety, stress, an indentation of the shaft at the site where there is plaque or scarring, and an angulation of the penis when erect or flaccid. There is no cure for Peyronie's disease, however, there are medications that can reduce symptoms of the disease. Surgery or penile implants may be an option for severe cases.
-
Dilated CardiomyopathyDilated cardiomyopathy causes the heart muscles to progressively enlarge and weaken, reducing the ability of the heart to pump enough blood.

What Is High Blood Pressure (Hypertension)?High blood pressure or hypertension is when the blood pressure readings consistently range from 140 or higher for systolic or 90 or higher for diastolic. Blood pressure readings above 180/120 mmHg are dangerously high and require immediate medical attention.
-
PhobiasPhobias are unrelenting fears of activities (social phobias), situations (agoraphobia), and specific items (arachnophobia). There is thought to be a hereditary component to phobias, though there may be a cultural influence or they may be triggered by life events. Symptoms and signs of phobias include having a panic attack, shaking, breathing troubles, rapid heartbeat, and a strong desire to escape the situation. Treatment of phobias typically involves desensitization, cognitive behavioral therapy, and medications such as selective serotonin reuptake inhibitors and beta-blockers.
-
AgoraphobiaAgoraphobia is a fear of being outside or of being in a situation from which escape would be impossible. Symptoms include anxiety, fear, disorientation, rapid heartbeat, diarrhea, or dizziness. Treatment may incorporate psychotherapy, self-exposure to the anxiety-causing situation, and medications such as SSRIs, benzodiazepines, and beta-blockers.

Bleeding VaricesVarices are dilated blood vessels usually in the esophagus or stomach. Symptoms of bleeding varices include vomiting blood, black stools, low blood pressure, shock, and rapid heart rate. Bleeding varices are a medical emergency. Treatment may involve liver transplant, devascularization, distal splenorenal shunt, banding, sclerotherapy, or transjugular intrahepatic protosystemic shunt.
-
Cardiomyopathy (Restrictive)Restrictive cardiomyopathy, the rarest form of cardiomyopathy, is a condition in which the walls of the lower chambers of the heart (the ventricles) are abnormally rigid and lack the flexibility to expand as the ventricles fill with blood. The pumping or systolic function of the ventricle may be normal but the diastolic function (the ability of the heart to fill with blood) is abnormal. Therefore, it is harder for the ventricles to fill with blood, and with time, the heart loses the ability to pump blood properly, leading to heart failure.
