Atenolol, sold under the trademark Tenormin, is a prescription drug used to treat high blood pressure.
It is also used to treat angina and chest pain, and has been shown to improve the condition after a heart attack, reducing the severity of a heart attack.
Reducing high blood pressure can also reduce kidney problems.
Atenolol belongs to a class of drugs known as beta-blockers that help control cardiovascular disease, slowing the heart and reducing its workload, thereby reducing blood pressure.
The drug is manufactured by AstraZeneca and is now available in forms manufactured by other companies.
Atenolol was approved by the Food and Drug Administration (FDA) in 1981 to treat high blood pressure and coronary artery disease.
It is also used to treat cardiac arrhythmias, such as supraventricular tachycardia and irregular ventricular rhythms.
Atenolol should be used regularly to be effective.
People with high blood pressure often do not feel sick, but the medicine should be taken even when you feel healthy.
Your doctor may prescribe other medicines, such as nitroglycerin (placed under the tongue) to reduce chest pain.
The use of atenolol should never cease suddenly, as this can worsen heart disease or blood pressure.
Pregnancy and atenolol
Atenolol is not recommended during pregnancy, as this can harm an unborn baby.
In addition, consult your doctor before breastfeeding.
It is proved that atenolol enters the breast milk and can harm the infant.

While atenolol causes minor side effects of the central nervous system, such as depression and nightmares, it has been identified as an increased risk of developing type 2 diabetes.
Beta-blockers mask dangerously low blood sugar levels, which makes them less safe for people with diabetes.
Tell your doctor about any allergies that you have, and about all the medicines that you take, as they can affect the work of Atenolol and vice versa.
Do not take atenolol if you are allergic to it. Inactive ingredients can cause allergic reactions.
Make sure your doctor knows that you have heart rhythm problems; problems with breathing, such as asthma, emphysema and chronic bronchitis; Kidney disease; problems with blood circulation; or severe allergies.
Atenolol may mask signs of low blood sugar, such as fast heartbeats (often associated with hypoglycemia), and may make it difficult to control blood sugar levels.
Dosage of atenolol
Atenolol tablets are round, white and flat and contain 25 milligrams (mg), 50 mg and 100 mg.
- The initial dose of arterial hypertension is 50 mg, which is given in the form of one tablet a day, with the effect observed for one to two weeks.
- From angina, the initial dose is 50 mg, which is given in the form of one tablet a day. But if the optimal response is not reached within one week, the dose increases to 100 mg, like one tablet a day.
- In patients with acute myocardial infringement, IV treatment will be initiated in the coronary care unit.
Atenolol is taken orally, with or without food, usually once or twice a day.
Avoid apple and orange juice for four hours after taking the drug, since juice prevents the absorption of the drug.
Overdose of atenolol
In case of an overdose, call an emergency.
Treatment of an atenolol overdose is symptomatic and can concern such problems as acute heart failure, bradycardia, hypotension or hypoglycemia.
The missed dose of atenolol
Take the missed dose as soon as you remember.
Do not take additional medication to make up for the missed dose.
