IONTOPHORETIC DELIVERY DEVICE |
摘要 |
An iontophoretic agent delivery device adapted to transdermally deliver an ionic agent, and a method of using same, are provided. The device has first and second electrodes connected to a source of electrical power. The first electrode is associated with a first agent reservoir and the second electrode is associated with a second agent reservoir. The device is adapted to deliver an agent, the agent having an isoelectric point at a specified pH, from both of the agent reservoirs simultaneously. This is accomplished by adjusting the pH of the first reservoir to a level above the isoelectric point of the agent while adjusting the pH of the second agent reservoir to a level below the isoelectric point. The device and method are particularly useful in iontophoretically delivering amino acids, polypeptides and proteins.
