  • Publication number: 20060166999
    Abstract: The invention relates to the use of inhibitors of the microsomal triglyceride transfer protein (MTP) for reducing the number of postprandial triglyceride-rich lipoprotein particles (ppTRL) or for reducing their decomposition products i.e. the cholesterol-rich ‘small remnant particle’ (remnants).
