  • Oral DTPA for radionuclide chelation
    Patent number: 7914767
    Abstract: A composition for oral radionuclide chelation therapy comprises a DTPA chelate selected from Zn-DTPA and Ca-DTPA and a permeation enhancer that preferentially increases jejunal uptake of the DTPA chelate. The composition has a DTPA chelate bioavailability of at least 10% of the chelate when orally administered to a mammal.
    Type: Grant
    Filed: February 14, 2007
    Date of Patent: March 29, 2011
    Assignee: SRI International

  • Bioadhesive delivery system for transmucosal delivery of beneficial agents
    Patent number: 7592021
    Abstract: Formulations and methods for transmucosal delivery of a beneficial agent are described in which a pH-responsive component and a temperature-responsive component are combined and applied to a mucous membrane. The temperature-responsive component is a component that, in aqueous solutions, is capable of undergoing a temperature-dependent sol to gel phase transition. The formulations may be characterized as having bioadhesive properties, and are suitable for delivery of a variety of beneficial agents.
