Atenolol is in a group of drugs called beta-blockers. Beta-blockers affect the heart and circulation (blood flow through arteries and veins). Atenolol is used to treat angina (chest pain) and hypertension (high blood pressure). It is also used to treat or prevent heart attack. Atenolol may also be used for purposes other than those listed in this medication guide.
Tenormin belongs to the group of drugs referred to as beta blockers that is primarily used in cardiovascular diseases. Tenormin was introduced in the year 1976 to replace propranolol that was employed in the treatment of high blood pressure or hypertension. It works by slowing down the heartbeat.
Tenormin (Atenolol) is a receptor antagonist. This drug can be used alone or in combination with other drugs to treat conditions such as high blood pressure, supraventricular tachycardia, acute myocardial infarction, angina, long QT syndrome, as well as the symptoms of alcohol withdrawal. Because of its diuretic properties, Tenormin is also used to prevent migraine headaches.
Tenormin is categorized under a class of medications known as beta blockers. Tenormin works by blocking the activities of certain chemicals that occur naturally in the body such as epinephrine in the blood vessels and the heart. This, in turn, reduces the heart rate, blood pressure, and the strain subjected to the heart.
