Structure
Colestipol is a non-absorbed, cross-linked polyallylamine derivative with quaternary ammonium groups, functioning as a bile acid sequestrant.
Chemical Formula: (C₃H₇NCl)ₙ·(C₇H₁₅O₄S)ₙ
Mode of Action
Bile Acid Sequestration: Binds bile acids in the gastrointestinal tract, preventing their reabsorption.
Cholesterol Synthesis Reduction: Increases the conversion of cholesterol to bile acids in the liver.
LDL-C Lowering: Enhances clearance of LDL-C from the bloodstream by upregulating hepatic LDL receptors.
Uses of Colestipol
Hypercholesterolemia: Reduces LDL-C and total cholesterol levels.
Type 2 Diabetes Mellitus: Used in combination with insulin or other hypoglycemic agents to manage hyperlipidemia.
Diarrhea Management: Treats bile acid-induced diarrhea by sequestering excess bile acids.
