What Is Questran?
Questran (cholestyramine) for Oral Suspension is a cholesterol-lowering agent used to lower high levels of cholesterol in the blood, especially low-density lipoprotein (bad cholesterol). Questran powder is also used to treat itching caused by a blockage in the bile ducts of the gallbladder. The brand name Questran is discontinued in the U.S. Generic forms may still be available.
Cholestyramine⁚ Mechanism of Action
Colestyramine acts as a bile acid sequestrant by binding to bile in the gastrointestinal tract, preventing its reabsorption. This resin can exchange chloride anions with anionic bile acids, forming strong bonds. By removing bile acids from the body, colestyramine prompts the liver to convert more plasma cholesterol into bile acids, consequently reducing overall blood cholesterol levels.
Uses of Questran
Questran has multiple uses, primarily as a cholesterol-lowering agent targeting high levels of LDL cholesterol. It is also utilized in the treatment of itching caused by bile duct blockage. Additionally, Questran is employed for managing conditions like diarrhea resulting from bile acid malabsorption. Its bile acid sequestrant properties make it beneficial in various gastrointestinal disorders.
Cholesterol-Lowering Properties
Questran exerts its cholesterol-lowering effects by binding to bile acids in the intestine, leading to the removal of excess bile acids from the body. This process triggers the liver to convert more plasma cholesterol into bile acids, thereby reducing the overall levels of cholesterol in the bloodstream. By aiding in this conversion, Questran plays a crucial role in managing high cholesterol levels.
Treatment of Itching and Bile Duct Blockage
Questran serves as an effective treatment for itching resulting from bile duct blockage by aiding in the removal of excess bile acids. The medication acts by binding these bile acids in the gastrointestinal tract, preventing their reabsorption and facilitating their elimination from the body through feces. This process not only alleviates itching but also addresses the underlying bile duct obstruction.
