ACTION AND CLINICAL PHARMACOLOGY
Ursodiol, a naturally occurring bile acid, is present as a minor
fraction of the total human bile acids. Oral
administration of ursodiol increases this fraction in a dose related
manner, to become the major biliary acid.
Since in patients with gallstones, the total bile acid pool size is
generally reduced, the exogenous supply of
ursodiol helps to increase this bile acid pool size and increases the
cholesterol saturation index. In addition,
the fecal bile acid loss is increased and cholesterol secretion into
the bile is reduced, without a concomitant
reduction in phospholipids. Consequently, the cholesterol saturation
of bile is reduced, allowing gradual
solubilization of cholesterol from gallstones to occur.
