ABSTRACT:
Methods for delivering therapeutic agents by iontophoresis with reduced or mitigated sensation are disclosed. The methods generally involve the step of delivering therapeutic agent by iontophoresis in the presence of an intentionally added sensation reducing amount of a multivalent ion. Preferred multivalent ions useful to mitigate sensation are calcium, magnesium, phosphate and zinc.
