<p>Improved electrotransport of therapeutic agents which include agent cations and polybasic anionic counter-ions is provided. Improved electrotransport is obtained by treating the therapeutic agent with a multivalent metal compound of the formula (MX) where M is a metallic cation having a valency of at least +2 and is reactive with the polybasic anionic counter-ion and X is a pH-increasing anion. Reduction in species which compete with the therapeutic agent for electrotransport delivery into the patient is obtained.</p> |
