Tenormin is licensed to control high blood pressure, relieve chest pain caused by angina, and improve survival following a heart attack. Some "off-label" Tenormin uses include treating hyperthyroidism, anxiety, and arrhythmias. Tenormin can also be used off-label to treat a number of conditions seen in children (for example, slowing the progression of aortic dilation in children with Marfan syndrome).
In previous clinical studies, Tenormin has been shown to significantly lower systolic and diastolic blood pressure. The higher the dose of Tenormin, the greater the drop in blood pressure is expected to be. By lowering blood pressure, Tenormin can decrease the risks that occur with long-term high blood pressure (see Effects of High Blood Pressure). Tenormin does not, however, cure high blood pressure.
Angina
Angina is a type of heart disease that occurs when the heart muscle is not getting enough nutrient- and oxygen-rich blood for a short period of time. The inadequate blood flow is caused by narrowed coronary arteries (the blood vessels that supply blood to the heart). Chest pain is the most common angina symptom that occurs (see Angina Symptoms for other symptoms of angina).
Tenormin is effective at treating symptoms of angina because it decreases the workload of the heart. This, in turn, means that the heart needs less oxygen- and nutrient-rich blood to function properly at any given level of effort. Tenormin does not cure this type of heart disease.
