Bile acid sequestrants are the main agents used to treat bile acid malabsorption. Cholestyramine and colestipol, both in powder form, have been used for many years. Unfortunately, many patients find them difficult to tolerate; although the diarrhea may improve, other symptoms such as abdominal pain and bloating may worsen. Colesevelam is a tablet and some patients tolerate this more easily. A proof of concept study of the farnesoid X receptor agonist obeticholic acid has shown clinical and biochemical benefit.
