Methods for preparing polymeric buffer formulations for electrotransport applications |
摘要 |
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.
