An iontophoretic method for transporting compounds of interest across a body tissue is provided. The method utilizes an AC signal in conjunction with a barrier-modifying agent such as a fatty acid, fatty alcohol, bile acid, surfactant, or the like. The method enables the maintenance of a substantially constant electrical state in a localized region of the tissue through which transport occurs, thereby allowing a compound of interest to be transported across the tissue in a controlled and predictable manner. The barrier-modifying agent reduces the time as well as the voltage level required to achieve a target electrical resistance, thereby reducing patient discomfort and increasing the battery life of the iontophoresis device.
提供了一种通过人体组织运输相关化合物的离子渗透方法。该方法利用交流信号与诸如脂肪酸、脂肪醇、胆汁酸、表面活性剂或类似物等屏障改良剂相结合。该方法可在组织的局部区域保持基本恒定的电状态,从而使相关化合物以受控和可预测的方式通过组织进行传输。屏障改良剂可减少达到目标电阻所需的时间和电压水平,从而减轻病人的不适感,延长离子透入装置的电池寿命。
