Cholesterol Absorption Inhibitor
inhibits the intetinal absorption of cholesterol; lowers LDL, raises HDL
cholesterol absorption inhibitor
side effects: infrequent, but may include headache and mild GI distress
cholesterol absorption inhibitor
nursing implication: may be combined with a statin- ezetimibe/simvastin; monitor AST and ALT
cholesterol absorption inhibitor
cholestyramine/ colestipol/ colesevelam

binds with bile acids in intestine, forming insoluble complex and excreted in feces. binding results in removal of LDL and cholesterol
bile acid sequestrants
side effects: unpleasant quality to taste, GI disturbances (indegestion, constipation, bloating)
