ELECTROCHEMICAL METHOD AND DEVICE FOR DRUG DELIVERY

摘要

2131086 9317755 PCTABS00025 An iontophoretic device for drug delivery may be powered by producing the necessary electropotential to deliver the drug using a difference in concentration of a salt across an anion selective membrane and a cation selective membrane, thereby creating an electropotential between the membranes. A membrane M that is permeable to electrolyte ions and, if present, drug borders the salt reservoirs and makes contacts with body to be treated.
