  • Compositions and methods for enhancing paracellular permeability across epithelial and endothelial barriers
    Patent number: 7713949
    Abstract: Compositions and methods for enhancing paracellular permeability at an absorption site in a subject are disclosed. The method includes: (a) administering an effective amount of a phospholipase C inhibitor to a subject at a time in which enhanced paracellular permeability is desired; and (b) enhancing paracellular permeability in the subject at the absorption site through the administering of the effective amount of the phospholipase C inhibitor. The disclosed compositions and methods provide enhanced absorption of a hydrophilic drug in a subject.
