Atenolol
Pronounced: a-ten-oh-lole
Other Name(s): Tenormin
Atenolol, a type of medication known as a beta-blocker, is used in the treatment of high blood pressure, angina pectoris (chest pain, usually caused by lack of oxygen in the heart muscle due to clogged arteries), and heart attack. When used for high blood pressure it is effective alone or combined with other high blood pressure medications, particularly with a thiazide-type water pill (diuretic). Beta-blockers work by affecting the response to some nerve impulses in certain parts of the body. As a result, they decrease the heart's need for blood and oxygen by reducing its workload. They also help the heart to beat more regularly. Occasionally doctors prescribe Atenolol for treatment of alcohol withdrawal, prevention of migraine headache, and bouts of anxiety.
ADULTS

The usual starting dose is 50 milligrams a day in 1 dose, alone or with a diuretic. Full effects should be seen in 1 to 2 weeks. Dosage may be increased to a maximum of 100 milligrams per day in one dose. Your doctor can and may use this medication with other high blood pressure medications.
Angina Pectoris
The usual starting dose is 50 milligrams in 1 dose a day. Full effects should be seen in 1 week. Dosage may be increased to a maximum of 100 milligrams per day. In some cases, a single dose of 200 milligrams per day may be given. Dosage will be individualized by your doctor.
Heart Attack
This medication may be used in the acute treatment of heart attack in both injectable and tablet form. Your doctor will determine the proper dosage.
CHILDREN
The safety and effectiveness of Atenolol have not been established in children.
OLDER ADULTS
The doctor will determine the dosage for an older individual, according to his or her needs, especially in the case of reduced kidney function.
