An
improved method and composition for the treatment of
hyperlipidemia, hypercholesterolemia, and
hypertriglyceridemia as well as other
disease states, particularly cardiovascular problems, uses a multiple release
system that provides an
immediate release of nicotinic acid followed by a subsequent release of nicotinic acid from the
hydrolysis of a compound that generates nicotinic acid. In general, a composition according to the present invention comprises: (1) a quantity of nicotinic acid intended to saturate liver enzymes during a period from about 0.5 hours to about 2.5 hours after administration of the pharmaceutical composition but insufficient to trigger significant generation of
nicotinuric acid; (2) a quantity of a derivative or analogue of nicotinic acid that is subject to
hydrolysis after
ingestion such that preferrably no more than about 10% of the derivative or analogue is hydrolyzed by about 8 hours after
ingestion and such that substantially all of the derivative or analogue is hydrolyzed by about 12 hours after
ingestion; and (3) at least one pharmaceutically acceptable carrier.
