Colestipol is a medication primarily used to lower cholesterol levels in the blood. It belongs to a class of drugs known as bile acid sequestrants, which work by binding to bile acids in the intestines. This binding process helps to reduce the absorption of cholesterol, leading to lower levels of low-density lipoprotein (LDL) cholesterol, often referred to as "bad" cholesterol. Patients typically take colestipol in the form of a tablet or granules mixed with water. It is usually prescribed alongside a healthy diet and lifestyle changes to enhance its effectiveness. Common side effects may include gastrointestinal issues, such as constipation or bloating, but these can often be managed with dietary adjustments.
