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 the enterohepatic circulation. The liver then produces more bile acids to replace those that have been lost.
The simplest 24-carbon bile acid has two hydroxyl groups at positions 3α and 7α. This is 3α,7α-dihydroxy-5β-cholan-24-oic acid, or, as more usually known, chenodeoxycholic acid. This bile acid was first isolated from the domestic goose, from which the "cheno" portion of the name was derived (Greek: χήν = goose). The 5β in the name ...
Bile acid sequestrants (resins, e.g. cholestyramine) are particularly effective for lowering LDL-C by sequestering the cholesterol-containing bile acids released into the intestine and preventing their reabsorption from the intestine. It decreases LDL by 15–30% and raises HDL by 3–5%, with little effect on triglycerides, but can cause a ...
Colesevelam is part of a class of drugs known as bile acid sequestrants. Colesevelam hydrochloride, the active pharmaceutical ingredient in Welchol, is a non-absorbed, lipid-lowering polymer that binds bile acids in the intestine, impeding their reabsorption. As the bile acid pool becomes depleted, the hepatic enzyme, cholesterol 7-α ...

Managing cholesterol at the site of absorption is an increasingly popular strategy in the treatment of hypercholesterolemia [citation needed].Cholesterol absorption inhibitors are known to have a synergistic effect when combined a class of antihyperlipidemics called statins, to achieve an overall serum cholesterol target.
Cholangiocytes act through bile-acid independent bile flow, which is driven by the active transport of electrolytes. In contrast, hepatocytes secrete bile through bile-acid dependent bile flow, which is coupled to canalicular secretion of bile acids via ATP-driven transporters. This results in passive transcellular and paracellular secretion of ...
Colestilan (INN, trade name BindRen) is a medication that acts as a phosphate binder [1] and bile acid sequestrant. [2] It is an ion-exchange resin, is an orally administered bile acid sequestrant that is being developed by Mitsubishi Tanabe Pharma Corporation for the treatment of hypercholesterolaemia and hyperphosphataemia.
