Atenolol, a beta blocker, is a prescription drug which is prescribed for the treatment of high blood pressure (hypertension) and chest pain (angina). The medication essentially slows down the heart rate, making it easier for the heart to keep up and not become overloaded.
The original purpose of the medication when it was developed in 1976 was to replace a medication called propranolol for the effective treatment of hypertension. Atenolol is preferred over propranolol because it does not have the same central nervous system side effects that propranolol does, because it does not pass through the blood-brain barrier.
It should be taken exactly as directed. Do not alter or skip a dose, and do not double up on it if you miss a dose, as this can cause Atenolol overdose. Symptoms include breath shortness, feeling dizzy or weak, fainting, seizure, or an unsteady heart rate. It is important that you take it with a full glass of water, at the same time each day so that the medication will always stay working in your system.
Although atenolol shows good results, there are several potential side effects.
Talk to your doctor if you experience sleeping difficulties (such as inability to fall asleep), or have been feeling more tired than usual. Some mild or moderate effects require that you discuss the problem with your doctor, but you may not need to seek emergency medical care. Atenolol can also cause nervousness or anxiety to occur, be sure to mention to your doctor if you have been experiencing either as a result of taking the drug. Seek emergency assistance if you experience a feeling of lightheadedness or fainting, shortness of breath, uneven heart rate or heart pounding/racing, sudden swelling of your feet or ankles, stomach pain, appetite loss nausea/vomiting or a discoloration of your skin or eyes (jaundice).
Patients who have had a history of bronchial asthma or hypothyroid disease should use extreme caution when taking this medication. Some conditions may interact with Atenolol(CAS: 29122-68-7) and cause complications. Vitamin supplements also might have an adverse effect on the benefits. For this reason, the patient should discuss any other medications taken regularly with the prescribing physician before taking it.
