Is Metoprolol in the Same Drug Family as Atenolol

Metoprolol vs. atenolol: What's the difference?

• Metoprolol and atenolol are beta-blockers used to treat high claret force per unit area (hypertension), heart hurting (angina), congestive heart failure, hyperthyroidism, abnormal heart rhythms, and some neurologic conditions.
• Metoprolol is also used to forbid migraine headaches.
• Brand names for metoprolol include Lopressor and Toprol XL.
• A brand proper noun for atenolol is Tenormin.
• Side furnishings of metoprolol and atenolol that are similar include abdominal cramps, diarrhea, constipation, fatigue, insomnia, nausea, depression, dreaming, memory loss, fever, impotence, lightheadedness, low claret force per unit area, common cold extremities, and sore pharynx.
• Side effects of metoprolol that are different from atenolol include indigestion, decreased do tolerance, increased triglycerides, bronchospasm, shortness of breath, or wheezing.
• Side effects of atenolol that are different from metoprolol include boring middle rate, abnormal heart rhythm, numbness, and tingling.

What are metoprolol and atenolol?

Metoprolol is a beta-blocker (beta-adrenergic blocking agent), which blocks the action of the sympathetic nervous organisation (a portion of the involuntary nervous arrangement) and is used to treat high blood pressure (hypertension), eye pain (angina), congestive middle failure, hyperthyroidism, abnormal heart rhythms, and some neurologic conditions. Metoprolol is also used to foreclose migraine headaches.

Atenolol is a beta-blocker that blocks the effects of adrenergic chemicals such as adrenaline or epinephrine, which are released past nerves of the sympathetic nervous organisation. The beta-adrenergic fretfulness stimulate the heart muscle to beat more chop-chop. Past blocking the stimulation by these nerves, atenolol reduces the eye rate and is used to treat abnormally rapid heart rhythms. Atenolol also reduces the force of contraction of middle muscle and lowers blood pressure. Past reducing the heart rate, the force of musculus contraction, and the blood pressure level against which the heart must pump, atenolol reduces the work of heart muscle and the need of the muscle for oxygen, which helps in treating angina.

What are the side furnishings of metoprolol and atenolol?

Metoprolol

Metoprolol is generally well tolerated. Side effects include:

• Abdominal cramps
• Diarrhea
• Constipation
• Fatigue
• Insomnia
• Indigestion
• Nausea
• Low
• Dreaming
• Memory loss
• Fever
• Impotence
• Lightheadedness
• Low blood force per unit area
• Decreased practise tolerance
• Increased triglycerides
• Bronchospasm
• Cold extremities
• Sore throat
• Shortness of jiff or wheezing

Possible serious adverse effects include

• Slow center rate
• Raynaud's miracle
• Hepatitis
• Increased insulin resistance

Metoprolol can beal breathing difficulties in patients with asthma, chronic bronchitis, or emphysema.

WARNING:

• In patients with existing slow centre rates (bradycardias) and heart blocks (defects in the electrical conduction of the centre), metoprolol can cause dangerously slow centre rates, and fifty-fifty daze. Metoprolol reduces the strength of heart muscle contraction and tin can beal symptoms of center failure. In patients with coronary artery affliction, abruptly stopping metoprolol tin suddenly worsen angina, and occasionally precipitate heart attacks. If information technology is necessary to discontinue metoprolol, its dosage should be reduced gradually over several weeks.
• Initiation of high-dose extended release metoprolol in patients undergoing non-cardiac surgery is associated with bradycardia (slow heart rate), hypotension, stroke, and death. Notwithstanding, long-term therapy with metoprolol should not be routinely withdrawn prior to major surgery. Dumb power of the heart to answer to reflex adrenergic stimuli may increase the risks of full general anesthesia and surgery.

Atenolol

Atenolol is by and large well tolerated, and side effects are mild and transient. Its side effects include:

• Abdominal cramps
• Diarrhea
• Constipation
• Fatigue
• Insomnia
• Nausea
• Depression
• Dreaming
• Memory loss
• Fever
• Impotence
• Lightheadedness
• Dull heart charge per unit
• Abnormal heart rhythm
• Depression blood pressure
• Numbness
• Tingling
• Common cold extremities
• Sore pharynx

Atenolol can cause breathing difficulties in patients with asthma, chronic bronchitis, or emphysema. In patients with existing ho-hum heart rates (bradycardias) and eye blocks (defects in the electrical conduction of the center), atenolol can cause dangerously slow middle rates and even shock. Atenolol reduces the forcefulness of heart muscle contraction and tin can beal symptoms of center failure.

In patients with coronary artery disease, abruptly stopping atenolol can suddenly worsen angina, and occasionally precipitate heart attacks. If it is necessary to discontinue atenolol, its dosage tin can exist reduced gradually over several weeks.

Metoprolol

• Calcium aqueduct blockers and digoxin (Lanoxin) can lower blood pressure and heart rate to dangerous levels when administered together with metoprolol.
• Metoprolol can mask the early warning symptoms of depression claret saccharide (hypoglycemia) and should exist used with caution in patients receiving handling for diabetes.
• Fluoxetine (Prozac) tin can increase claret levels of metoprolol by reducing breakup of metoprolol, and increase the side effects from metoprolol.

Atenolol

• Calcium channel blockers (CCBs) and digoxin (Lanoxin) can crusade lowering of blood pressure and eye rate to dangerous levels when administered together with atenolol.
• Atenolol can mask the early warning symptoms of low blood sugar (hypoglycemia), and should be used with circumspection in patients receiving treatment for diabetes.

  Loftier Blood Pressure (Hypertension)

  High blood pressure (hypertension) is a disease in which pressure level inside the arteries of the trunk is elevated. About 75 million people in the US have hypertension (i in 3 adults), and but half of them are able to manage it. Many people exercise not know that they accept loftier blood pressure because it oft has no has no alert signs or symptoms. Systolic and diastolic are the two readings in which claret force per unit area is measured. The American College of Cardiology released new guidelines for loftier blood pressure in 2017. The guidelines now state that blood normal claret pressure is 120/fourscore mmHg. If either ane of those numbers is higher, you lot have high blood pressure. The American University of Cardiology defines high claret pressure slightly differently. The AAC considers 130/80 mm Hg. or greater (either number) stage 1 hypertension. Stage 2 hypertension is considered 140/ninety mm Hg. or greater. If you have high blood pressure you are at run a risk of developing life threatening diseases like stroke and heart assault.REFERENCE: CDC. Loftier Blood Force per unit area.

  Portal hypertension is most commonly caused by cirrhosis, a illness that results from scarring of the liver.

Symptoms of portal hypertension include varices (enlarged veins), vomiting claret, blood in the stool, blackness and tarry stool, ascites (aberrant fluid collection inside the peritoneum, the sac that contains the intestines within the abdominal crenel), confusion and lethargy, splenomegaly or enlargement of the spleen, and decreased white blood cell counts.

  Pulmonary Hypertension

  Pulmonary hypertension is elevated pressure in the pulmonary arteries that bear claret from the lungs to the heart. The most common symptoms are fatigue and difficulty breathing. If the condition goes undiagnosed, more severe symptoms may occur. As pulmonary hypertension worsens, some people with the condition take difficulty performing any activities that require physical exertion. While at that place is no cure for pulmonary hypertension, information technology tin can be managed and treated with medications and supplemental oxygen to increase blood oxygen levels.

  High blood pressure tin damage the kidneys and is one of the leading causes of kidney failure (end-stage renal kidney illness). Kidney damage, like hypertension, can be unnoticeable and detected only through medical tests. If you have kidney disease, you should command your blood pressure. Other treatment options include prescription medications.

The crusade is unknown. The virtually common symptom is headache but also include eye-pain, vision loss and double vision. Pseudotumor cerebri is diagnosed with MRI or True cat scans and treated by discontinuing offending medications (if applicable), weight loss and diuretic medications. The condition can also be helped by repeated drainage of spinal fluid using the lumbar puncture.
