Abstract
Improved electrotransport of therapeutic agents which include agent cations and polybasic anionic counterions. 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 electrotranport is obtained.
