Amitriptyline-induced prolonged cholestasis.

abstract：:Sweden has one of the highest incidences of gallstone disease in the Western world. It is therefore important to characterize the mechanisms responsible for the formation of cholesterol gallstones in this population. In the present study, we have determined the kinetics of the two primary bile acids, cholic acid and c...
