Advances in materials science and bionanotechnology have allowed the refinements of current drug delivery systems, expected to facilitate the development of personalized medicine. While dermatological topical pharmaceutical formulations such as foams, creams, lotions, gels, etc., have been proposed for decades, these systems target mainly skin-based diseases. To treat systemic medical condition...
Abstract Background Transdermal drug delivery is one of the most widely used administration routes, which offer several advantages over other routes delivery. The apical layer skin called stratum corneum dominant obstacle in transdermal delivery, restricts passage drugs across skin. Considerable strategies have been applied to enhance rate permeation epithelial cells; however, strategy use sorp...
Description of Procedure or Service Iontophoresis is a method of transdermal local drug delivery using electrical current. A charged, ionic drug is placed on the skin with an electrode of the same charge, allowing direct current to drive the drug into the skin. Ultrasound transdermal delivery involves the use of ultrasonic energy to enhance delivery of solutes either simultaneously or via pre-t...
The use of enhancers to increase the drug molecules penetration into target tissues is an usual technique in drug delivery. In transdermal drug delivery, electric fields are often used to increase the drug transport through the skin. In this paper we study a drug delivery mechanism from a reservoir which is in contact with the skin. We assume that the drug transport in the coupled system is enh...
Sonophoresis can increase skin permeability to various drugs in transdermal drug delivery. Cavitation is recognized as the predominant mechanism of sonophoresis. Recently, a new logical approach to enhance the efficiency of transdermal drug delivery was tried. It is to utilize the engineered microbubble and its resonant frequency for increase of cavitation activity. Actively-induced cavitation ...
