  • Patent number: 5188836
    Abstract: Semi-enteric controlled release formulations are comprised of a biological active agent such as an antibiotic that is blended with a water-soluble bulking agent, the mix then coated onto an inert core. The coated active core is further coated with a mixture comprised of an acrylic copolymer, bulking agent and pH dependent food acid. These different coating components possess different solubility characteristics which result in a gradual release of the active in both the stomach and small intestine that provides an increased bioavailability of the active drug.
