Efficacy of cholestyramine does not vary when taken before or during meals.
Compliance to cholestyramine treatment, often unsatisfactory, may become further problematic because of the common indication that the resin should not be taken with meals. Since there is no convincing data on the validity of this therapeutic schedule, 10 type IIA hyperlipoproteinemic patients received cholestyramine either before or during the 3 major meals, according to a cross-over protocol. Plasma lipid levels were monitored after 4 and 6 weeks of each treatment schedule. The efficacy of the resin, in terms of total cholesterol (-16.5% together with food vs. -17.2% before food) and of low density lipoprotein cholesterol reduction (-22.8% with food vs. -23.1% before food) did not differ. The side effect profile was also not different between the two treatment protocols. These findings suggest that there are no significant interactions between food and the anion exchange resin and that the hypocholesterolemic effect does not depend upon a specific timing, supposedly close to the gallbladder contraction. They are particularly significant in view of the future availability of new resins in liquid form, suitable for intake during meals.
