Cholestyramine is a medicine that helps lower high cholesterol levels in your blood. It works by preventing your body from absorbing cholesterol in the intestines.
Propranolol is a medicine that can help with high blood pressure, chest pain, and other conditions. It works by blocking the effects of certain natural chemicals in your body, like adrenaline, that affect the heart and blood vessels.
This medicine is used with a diet to lower high cholesterol, especially LDL cholesterol (the "bad" cholesterol). It may also help if you have high triglycerides, but it's not the best choice if high triglycerides are your main problem. Lowering cholesterol helps reduce your risk of heart disease.
Propranolol tablets can treat high blood pressure. It can be used alone or with other medicines. Propranolol can also help with chest pain (angina), control fast heart rate with atrial fibrillation, improve survival after a heart attack, prevent migraine headaches, and reduce tremors. It can also help with symptoms of some tumors.

By binding to bile acids, cholestyramine prevents them from being reabsorbed, so your body uses cholesterol to make more bile acids, which lowers cholesterol levels in your blood.
Propranolol is a beta-blocker. It works by blocking the effects of adrenaline on your heart and blood vessels. This helps to slow down your heart rate and lower your blood pressure.
