A nurse is responsible for patient education for a 48-year-old woman who has been prescribed colestipol. The nurse will instruct the patient to take the medication Response Feedback: Colestipol is a bile acid sequestrant that promotes the oxidation of cholesterol to bile acids. Cholesterol is the major precursor to bile acids. Bile acids are secreted from the gallbladder and liver into the intestine during digestion. In the intestine, bile acids emulsify the fat and lipid particles from food, promoting absorption. Much of the bile acid that is secreted is reabsorbed and returned to the liver by hepatic circulation. Colestipol binds with the bile acids in the intestine to make them nonresorbable. The bile acids are then eliminated in the stool. Because of this mechanism of action, the drug should be administered before a meal. [Show More]
