  • Particulate composition of eletriptan
    Publication number: 20020034545
    Abstract: The invention provides a pharmaceutical composition in particulate form, suitable for oral administration, including a core containing eletriptan or a pharmaceutically acceptable salt thereof, the core being coated with a water-insoluble, permeable coating including one or more acrylic copolymer(s) containing trimethylammoniumethylmethacrylate groups, said composition being capable of achieving a sigmoidal pattern of controlled drug release. Such a pharmaceutical composition is particularly useful in the prevention of migraine recurrence.
