Hypocholesterolemic agents: a comparison of the relative effectiveness of cholestyramine and pectin in rats.
Studies were carried out to evaluate the comparative effectiveness of cholestyramine and pectin as hypocholesterolemic agents. Circulating levels of serum cholesterol and lipoprotein-associated cholesterol were measured in rats fed high cholesterol diet supplemented with either cholestyramine or pectin. When compared with controls, a significant decrease in the level of total cholesterol was observed in rats fed either cholestyramine or pectin (p less than 0.001, 43% reduction in cholesterol, and p less than 0.04, 25% reduction in cholesterol, respectively) and this was due exclusively to the lowering of low density lipoprotein. Further statistical evaluation of data revealed no significant difference between the cholesterol levels of rats fed either cholestyramine or pectin (p greater than 0.07). The data acquired in this study suggest that both cholestyramine and pectin are comparable and effective hypocholesterolemic agents and the observed hypocholesterolemic effect of these agents is mediated through lowering of cholesterol associated with the low density lipoprotein.
