What is propranolol sustained-release used for? This prescription medication is used to treat conditions related to the heart and blood vessels, including high blood pressure, angina, and hypertrophic subaortic stenosis. Some off-label uses for propranolol sustained-release include treating hyperthyroidism and anxiety disorders, as well as slowing down the progression of aortic dilation in children with Marfan syndrome.
In clinical studies, propranolol sustained-release has been shown to significantly lower systolic and diastolic blood pressures. The higher the dose of propranolol sustained-release, the greater the drop in blood pressure is expected to be. By lowering blood pressure, propranolol sustained-release can decrease the risks that occur with long-term high blood pressure (see Effects of High Blood Pressure). Propranolol sustained-release does not, however, cure high blood pressure.
