  • VECTOR FOR ORAL ADMINISTRATION
    Publication number: 20140120161
    Abstract: A vector for the oral administration of at least one pharmacologically active substance enabling the active substance to move from the intestinal lumen to the blood, optionally via interstitial liquid, without any substantial degradation of the substance, includes an essentially hydrophilic matrix having an outer surface which is modified by one or several chemical species providing the vector with an essentially lipophilic quality and containing one or several active substances. The vector is associated with a gastroresistant vehicle enabling it to pass into the stomach without any denaturation and/or degradation of the active substance. The invention also relates to pharmaceutical compositions containing the vector. The vectors can be used to produce medicaments used in human or veterinary medicine.
