A method of controlling hyperlipidemia in mammals which comprises adminstering to a mammal an amount effective to control hyperlipidemia of a compound having hypolipidemic activity and the structural formula: ##STR1## wherein R.sup.1 and R.sup.2, which may be the same or different provided both are not hydrogen when R.sup.3 is an alkenyl or cycloalkenyl group, are selected from the group consisting of hydrogen; alkyl of 1 to 18 carbons; substituted alkyl of 1 to 18 carbons; cycloalkyl of 4 to 10 ring carbon atoms; substituted cycloalky of 4 to 10 ring carbon stoms; alkoxy of 1 to 8 carbon atoms; amido; carbamoyl; acyloxy; alkoxycarbonyl; halogen, aryl and substituted aryl, or together R.sup.1 and R.sup.2 from a C.sub.3 to C.sub.7 alkylene group; and R.sup.3 is hydrogen; lower alkyl; substituted lower alkyl; cycloalkyl; substituted cyloalkyl; aryl; substituted aryl; a group --COR.sup.4 were R.sup.4 is hydrogen, lower alkyl, substituted lower alkyl, cycloalkyl, substituted cycloalkyl, aryl, or substituted aryl; a group --CONHR.sup.5 where R.sup.5 has the same meaning as R.sup.4 ; an alkoxycarbonyl group --CO.sub.2 R.sup.6 where R.sup.6 has the same meaning as R.sup.4 ; an alkenyl group --CR.sup.7 .dbd.CR.sup.8 R.sup.9 where R.sup.7, R.sup.8 and R.sup.9, which may be the same or different, have the same meaning as R.sup.4 ; a cycloalkenyl group ##STR2## where n is an integer from 3 to 8; or a group ##STR3## where R.sup.10 and R.sup.11 have the same meanings as R.sup.4 or together R.sup.10 and R.sup.11 form a C.sub.3 to C.sub.7 alkylene group, and R.sup.12 and R.sup.13, which may be the same or different, have the same meanings as R.sup.1 and R.sup.2, provided that R.sup.1 and R.sup.2 are not both hydrogen, the pharmaceutically acceptable salts, and mixtures thereof; and pharmaceutical compositions useful in practicing the method comprising the hypolipidemically active isoxazolidine-3,5-dione compounds and a pharmaceutically acceptable carrier.
