The liver then produces more bile acids to replace those that have been lost. Because the body uses cholesterol to make bile acids, this reduces the level of LDL cholesterol circulating in the blood. [2] Bile acid sequestrants are large polymeric structures, and they are not significantly absorbed from the gut into the bloodstream.
Colestipol (trade names Colestid, Cholestabyl) is a bile acid sequestrant used to lower blood cholesterol, specifically low-density lipoprotein (LDL). [1] [2] It is also used to reduce stool volume and frequency, and in the treatment of chronic diarrhea. [3]
Colestyramine or cholestyramine (trade names Questran, Questran Light, Cholybar, Olestyr) is a bile acid sequestrant, which binds bile in the gastrointestinal tract to prevent its reabsorption. It is a strong ion exchange resin , which means it can exchange its chloride anions with anionic bile acids in the gastrointestinal tract and bind them ...
Bile acids have other functions, including eliminating cholesterol from the body, driving the flow of bile to eliminate certain catabolites (including bilirubin), emulsifying fat-soluble vitamins to enable their absorption, and aiding in motility and the reduction of the bacteria flora found in the small intestine and biliary tract.
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 ...
Bile (yellow material) in a liver biopsy stained with hematoxylin-eosin in a condition called cholestasis (setting of bile stasi). Bile (from Latin bilis), or gall, is a yellow-green/misty green fluid produced by the liver of most vertebrates that aids the digestion of lipids in the small intestine.
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 ...
