[sītos′tərôl]
Etymology: Gk, sitos, food, stereos, solid; Ar, alkohl, essence
a mixture of sterols derived from plants, such as wheat germ, used for treating hyperbetalipoproteinemia and hypercholesterolemia that are unresponsive to other dietary measures. Its use is controversial, for a dispersing action in the mixture tends to cause loose bowel movements and may lead to diarrhea or interfere with the absorption of concomitantly administered medications. Use in pregnancy is not recommended.
