Atenolol is used to control high blood pressure, as it helps lower blood pressure to safe levels, thus reducing the risks associated with cardiovascular diseases such as stroke and heart attacks. It is also an effective treatment for angina pectoris, as it relieves the feeling of pain or pressure resulting from a lack of oxygen supply to the heart.
Atenolol is used to treat heart rhythm disorders such as abnormal heart rate, by regulating the electrical signals that manage the heartbeat rhythm. It can also be effective in preventing migraines in some patients and reducing the severity of the accompanying symptoms.
