Abstract

Recently there has been increased interest in the use of iontophoresis for the transdermal delivery of drugs, both ionic and nonionic. The use of iontophoresis has been rare over the years due to the lack of domestic supplies of the instrument and the expensive iontophoresis instrument made by foreign country. The purpose of this study was to design a commercially available iontophoresis system (WIT- 1 ). The efficacy of WT- 1 system was well defined. In clinical trial, procaine iontophoresis produced local anesthesia of significantly longer duration than swabbing and placebo groups. The 4% procaine iontophoresis using WIT-1 significant difference in anesthetic duration between WIT- 1 system and IontopherTM PM system. The result of this study suggest that WIT-1 system can be used for the transdermal delivery of drugs in various clinical conditions.
