Working Mechanism of Iontophoresis: A deep dive into how iontophoresis works, including the scientific principles that power it.

The Science Behind Transdermal Iontophoresis: Basic Principles and Mechanisms

Transdermal Iontophoresis is a topical drug delivery technique gaining increased recognition in the medical field. By using electrical currents to drive ions across skin barriers, this method has proven effective in delivering various types of drugs into the body. But what exactly is the science behind transdermal iontophoresis? To understand this, we must delve into its basic principles and mechanisms.

At its core, iontophoresis utilizes electricity as means to increase permeability through skin barriers. The human skin serves as an excellent protective barrier against foreign substances, including many medications. This characteristic makes it difficult for certain drugs to penetrate into systemic circulation when applied topically. However, iontophoresis can overcome this challenge by employing electrical current that facilitates drug penetration.

The fundamental principle of iontophoresis lies in physics – specifically the law of electrostatics which states that like charges repel each other while unlike charges attract each other. In terms of iontophoresis, a small electric current is applied across the skin which alters the distribution of ions at the application site. If a positively charged medication (cation) is used, it would be placed under a positive electrode (anode). When electricity is applied, the cation will be repelled from anode and driven towards negative electrode (cathode), penetrating through layers of skin.

Similarly with negatively charged drugs or anions: they will be pushed away from cathode and attracted towards anode thereby increasing their penetration into body tissues beneath the application site. This process bypasses traditional barriers posed by diffusion or molecular size restrictions.

The success of transdermal iontophoresis also depends on several factors such as duration and intensity of current applied, type and concentration of drug used and thickness & physical properties of patient's skin among others. It's also important to note that not all drugs are suitable for transdermal iontophoretic administration due to differences in their properties such as molecular size, charge and solubility.

In conclusion, the science behind transdermal iontophoresis is a blend of physics, biology and pharmacology. Its basic principle revolves around manipulating electrical charges to drive drugs across skin barriers. This method has shown potential in enhancing drug delivery for a variety of therapeutic conditions. However, more research is needed to optimize its protocols and expand its applications in medicine.
