Mechanism
Bile acid sequestrants are polymeric compounds that serve as ion exchange resins. Bile acid sequestrants exchange anions such as chloride ions for bile acids. By doing so, they bind bile acids and sequester them from enterohepatic circulation.
Since bile acid sequesterants are large polymeric structures, they are not well-absorbed from the gut into the bloodstream. Thus, bile acid sequestrants, along with any bile acids bound to the drug, are excreted via the feces after passage through the gastrointestinal tract.
