CE FEATURE: PDF OnlyTransdermal Drug Delivery Using Iontophoresis and PhonophoresisRoberts, DottieAuthor Information Dottie Roberts, MSN, RN,C, ONC, CNS, is a Medical/Surgical Clinical Nurse Specialist at Centura Health/Penrose-St. Francis Health Services in Colorado Springs, Colorado. Orthopaedic Nursing: May 1999 - Volume 18 - Issue 3 - p 50-54 Buy Abstract Introducing medicines into the human body by way of the skin is an ancient practice, and transdermal delivery has long been a standard for administering medications such as nitroglycerin and scopalamine. Phoresis, another method of transdermal drug delivery, is now being ordered for an increasing number of orthopaedic patients who suffer from inflammation, strains, or sprains. In phoretic drug delivery, enhancers such as electricity or ultrasound are used to stimulate drug absorption in the treatment area. To guide their patients to explore a variety of treatment options, orthopaedic nurses need a greater understanding of these phoretic modalities. © 1999 National Association of Orthopaedic Nurses
