Sitosterolemia
Sitosterolemia is a rare genetic condition in which
plant sterols found in food are absorbed within the intestines in greater-than-normal amounts and then not removed as well as they normally are. This causes high levels of sitosterol and campesterol (which are types of plant sterols) in the blood. Over time, this can result in
high cholesterol, deposits of
cholesterol (known as xanthoma) in tendons and other parts of the body, early
atherosclerosis (
hardening of the arteries), and certain blood and liver problems.
Zetia has been licensed to treat high levels of sitosterol and campesterol in the blood of people with homozygous familial sitosterolemia.
