Transdermal Iontophoretic Delivery Of Lipophilic Drugs, Abhishek Juluri

Electronic Theses and Dissertations

Iontophoresis is one of the most widely studied active technique for enhancing transdermal delivery of drugs. However, its ability to enhance the delivery of highly lipophilic compounds is poor due to lack of any charge and poor water solubility of molecules. Propofol, a sedative and anesthetic drug was chosen as a one of the model lipophilic drug in this study. Initially, feasibility of delivery of propofol phosphate, a water soluble prodrug of propofol, via transdermal route using iontophoresis in combination with chemical permeation enhancers was investigated. Cathodal iontophoresis in combination with 0.1% sodium dodecyl sulphate synergistically enhanced the flux of …
