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 salt diarrhea can also be a side-effect of gallbladder removal. [1] Bile acid sequestrants are the principal therapy for bile acid-induced diarrhea. [7] [1] Cholestyramine, colestipol and colesevelam have all been used. Doses may not need to be as high as those previously used for hyperlipidemia.
Postcholecystectomy syndrome (PCS) describes the presence of abdominal symptoms after a cholecystectomy (gallbladder removal).. Symptoms occur in about 5 to 40 percent of patients who undergo cholecystectomy, [1] and can be transient, persistent or lifelong.
Like cholestyramine, colestipol works in the gut by trapping bile acids and preventing them from being reabsorbed. This leads to decreased enterohepatic recirculation of bile acids, increased synthesis of new bile acids by the liver from cholesterol, decreased liver cholesterol, increased LDL receptor expression, and decreasing LDL in blood.
These side effects often lead to low patient compliance. [5] Colesevelam can be used instead of cholestyramine in symptomatic chronic diarrhea due to bile salt malabsorption (bile acid diarrhea), which can be a primary condition, or secondary to Crohn's disease or the postcholecystectomy syndrome.

If dietary treatment alone is insufficient, bile acid-binding resins (e.g., cholestyramine, colestipol) could be considered. In October 2002, a new cholesterol absorption inhibitor, ezetimibe, received US Food and Drug Administration (FDA) approval for use in sitosterolemia. This drug is now the standard of care, as it blocks sterol entry and ...
The most important adverse side effects are muscle problems, an increased risk of diabetes mellitus, and increased liver enzymes in the blood due to liver damage. [ 5 ] [ 65 ] Over 5 years of treatment statins result in 75 cases of diabetes, 7.5 cases of bleeding stroke , and 5 cases of muscle damage per 10,000 people treated. [ 34 ]
Diclofenac, sold under the brand name Voltaren among others, is a nonsteroidal anti-inflammatory drug (NSAID) used to treat pain and inflammatory diseases such as gout. [6] [9] It can be taken orally (swallowed by mouth), inserted rectally as a suppository, injected intramuscularly, injected intravenously, applied to the skin topically, or through eye drops.
