  • Publication number: 20070225632
    Abstract: A transdermal electrotransport drug delivery system to an individual. The system has a liquid imbibing polymer with carboxyl groups available for noncovalently associating with a cationic drug. The liquid imbibing polymer is applicable for imbibing liquid before the device is deployed on a patient for electrotransport drug delivery.

  • Publication number: 20050142531
    Abstract: Methods for preparing compositions for use in electrotransport delivery systems. The method includes providing a drug solution comprising drug ions and associated counterions; adjusting the pH of the drug solution by contacting the drug solution with a ion exchange material first; separating the ion exchange material from the pH-adjusted drug solution; and buffering the pH-adjusted drug solution with a buffer. A peptidic buffer is preferably used. The methods result in compositions suitable for use in electrotransport delivery systems.

  • Publication number: 20050129655
    Abstract: The present invention provides methods for preparing compositions for use in electrotransport delivery systems that comprise providing a drug solution comprising drug ions and associated counterions; adjusting the pH of the drug solution by contacting the drug solution with a first ion exchange material; separating the first ion exchange material from the pH-adjusted drug solution; adding the pH-adjusted drug solution to a reservoir of an electrotransport delivery system; and contacting the pH-adjusted drug solution with a second ion exchange material.
