B2 Reverse iontophoresis has the potential to be an at-home treatment versus the traditional method of kidney dialysis, which is usually administered at the hospital. The vast majority of those diagnosed with ESRD were treated with dialysis, the most common method being hemodialysis.?
In addition, the time required to do so would be much shorter than a typical kidney dialysis treatment and the packaging of the device would be self-contained so a patient could continue with normal daily activities in a manner not possible with traditional dialysis treatments.?
The current is delivered to skin while the hands or feet are immersed in pair of pans, each of, which has an electrode that is also in the water.
The pH is of importance for the iontophoretic delivery of drugs. This practice is as old as medicine itself.
The delivered dose depends on the current flowing and its duration. In addition, patients on dialysis could have side effects directly from the dialysis treatments, may need an altered diet, and may need to find a new job or career if their previous job required heavy lifting?

Sub-dermally, the ions introduced re-combine with the existing ions floating in the blood stream, forming the necessary new compounds for therapeutic interactions. Reverse iontophoresis has also been proven to iontophroesis monitor urea and potassium in in vitro experiments. It should be put into consideration that a few ions, ready to combine, may be better than a sum of ions, repelling each other because of their similar charges.
Iontophoresis Seminar Report pdf. Non-ionised compounds are generally better absorbed through the skin than ionised substances.
In addition, reverse iontophoresis could be extended to an unlimited number of capabilities.? With hemodialysis, an artificial kidney called a hemodialyzer is inserted into the body and connected to blood vessels with either a iontphoresis or fistula Figure 2.

Iontophoresis enhances the transdermal delivery of ionized drugs through the skin’s outermost layer stratum corneum which is the main barrier to drug transport. At the iontophorssis of this lecture the student must be able to: This is the concept of ion transfer. Until now, the combination LDPM laser Doppler perfusion monitoring and iontophoresis has been used mostly as a diagnostic tool for diseases affecting macro- and microcirculation and the controlling regulatory nerves.
Potentially, it can reduce the presence of the urea, potassium, phosphorus, and other constituents of the patient? About project SlidePlayer Terms of Service. For the method of reverse iontophoresis to be applicable as an alternative for kidney dialysis, its use as a technique of urea removal must first be proven.
Continuous DC current may result in skin polarisation, which can reduce the efficiency of iontophoretic delivery in proportion to the length of current application. It was determined through this study that it is possible to remove urea through reverse iontophoresis, and the concentration of urea present at the cathode of the iontophoresis controller Figure 4 was l inearly correlated with plasma urea.
The final barrier is that the pH of the skin must be kept around a neutral value of 7. In anodal iontophoresis positively charged ionsthe electrode orientation is reversed.
Some progress has been made in the portability of dialysis machines, however. Current methods of kidney dialysis are invasive and very time intensive for the patient.
Most researches have indicated that low-level amplitude is more effective than high-level intensities, as higher intensities adversely affect ionic penetration. When a negatively charged drug is to be delivered across an epithelial barrier which is placed under the negatively charged delivery electrode cathode from which it is repelled, to be attracted to the positive electrode placed elsewhere on the body.
When the pH decreases, the concentration of hydrogen ions increases, and a vascular reaction vasodilatation is initiated because of C-fibre activation fig.
Reverse iontophoresis is a process in which molecules are removed from within the body via a negative charge on the skin that causes solvent flow towards a cation9. Iontophoresis is a recognized therapeutic method for delivering ionic compounds, i.

Galvani and Volta, two well-known scientists working in the 18th century, combined iontophogesis knowledge that electricity can move different metal ions, and that movements of ions produce electricity.
Latest Seminar Topics for Engineering Students. The method has also been reported useful for topical anesthesia to the skin prior to cut-down for artificial kidney dialysis, insertion of tracheotomy tubes and infiltration of lidocaine into the skin prior to venipuncture.
The use of reverse iontophoresis is non-invasive and has the potential to dramatically reduce the amount of time necessary for treatment.
