Q: What is iontophoresis?: A: Iontophoresis is a method of active transdermal drug delivery. Some people call it an “electronic patch”. Iontophoresis is the delivery mechanism for transmitting a drug to a localized treatment area.
Q: How does iontophoresis work?: A: Instead of swallowing a pill or injecting a drug with a syringe, iontophoresis uses very low electrical current to delivery medication into the body.
Q: What are some medications that can be used in the Dupel iontophoresis system? What is the polarity of a specific medication?: A: A number of medications can be administered via iontophoresis depending on the clinical application. Medications for iontophoretic delivery, must: Have a polarity (-) or (+), Be water soluble (aqueous solution), Have a molecular weight lower than 8000 Daltons.
Q: Can iontophoresis safely be used with a patient who is pregnant?: A: The safety of iontophoresis with this patient population has not been established in the literature to date.
Q: How do I determine what is a normal histamine reaction from the direct current?: A: A transient erythematic reaction can sometimes occur directly under one or both of the electrodes as a result of treatment. This reaction, which has a uniform red pattern, will usually disappear within twelve hours of the treatment. Please contact Empi's clinical consultants for additional information.
Q: What can I do if my Dupel iontophoresis device keeps turning off?: A: To ensure effective drug delivery, the Dupel device has an alarm that will discontinue current delivery if a poor connection is detected along the current pathway. Several factors can improve the current flow, these include proper skin preparation, sufficiently hydrated skin, slow ramping up of the current intensity, and good adherence of the electrodes. Please contact Empi's clinical consultants for additional information.
Q: How do I determine what is the best dosage and total number of treatments for a patient?: A: The dosage and number of treatments depends on the desired outcomes and response of each patient. The standard dosage ranges from 40mA.min to 80mA.min. The total number of treatments varies depending on the patient's response, the medication being administered, and the severity of the condition. The frequency of treatments is affected by the characteristics of the particular drug used in the Dupel system, such as its active half-life.
Q: What literature is there to support the use of iontophoresis for a given diagnosis?: A: Please refer to our scientific evidence section.
