Abstract
Abstract Novel phenoxyalkylcarboxylic acid compounds of the formula <IMAGE> (I) wherein B is a valency bond or a straight-chained or branched, saturated or unsaturated hydrocarbon radical containing up to 3 carbon atoms; N IS 1 OR 2 AND R1, R2 and R3 are hydrogen or lower alkyl; and the pharmacologically compatible salts thereof; have been found to be outstandingly effective in lowering the serum lipid level and the cholesterol level in mammals without inducing undesired side effects and to possess excellent thrombocyte-aggregation inhibiting activity.
