    摘要： Preferential delivery via electrotransport of a preferred isomeric form of a pharmaceutically active chiral compound from a mixture of the isomeric forms of said compound is provided. A method of decreasing the delivery via electrotransport of a less preferred isomer of a drug is also provided. Drug delivery devices suitable for such preferential delivery and methods of making the same are also provided.

    摘要： 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.

    摘要： Electrotransport drug delivery devices, systems and methods for delivery of lofentanil or carfentanil are disclosed. The lofentanil or carfentanil may be provided as a water soluble salt (e.g., lofentanil or carfentanil hydrochloride), such as in a hydrogel formulation. A transdermal, electrotransport delivered dose of lofentanil or carfentanil is provided which is sufficient to induce analgesia in (e.g., adult) human patients suffering from chronic, acute and/or breakthrough pain.
