The History of Iontophoresis

In 1929, Robert A. Fischer moved from Chicago to California, bringing with him a background in engineering and physical therapy. After working with his brother at the H.G. Fischer Corporation, a company known for X-ray equipment, Fischer launched the Fischer Corporation before World War II. His early work was instrumental in developing a range of electro-medical devices, including shortwave diathermy machines, ultrasound equipment, and transcutaneous muscle stimulators. The company’s reputation for quality was built on Fischer’s dedication to creating advanced physical therapy solutions that were both effective and reliable.

During World War II, Fischer’s company temporarily shifted to manufacturing aircraft instrumentation but returned to its focus on physical medicine after the war. With the involvement of his wife, Anna, a registered nurse, R.A. Fischer & Company quickly gained recognition as a leader in physical therapy equipment. Fischer’s groundbreaking work also extended to “cold quartz” UVC spectrum ultraviolet lamps, used by dermatologists, and electrolysis technology for cosmetic treatments. His strategic location in Glendale, near Hollywood, allowed him to collaborate with major film studios, and his devices became fixtures in their medical clinics.

Robert A. Fischer made a significant mark on the field of iontophoresis, specifically in the treatment of hyperhidrosis. Using his engineering expertise, he refined iontophoresis technology, making it an accessible and practical solution for managing excessive sweating. Fischer's devices prioritized user safety and comfort, incorporating features like adjustable current settings and non-invasive applications. These advancements provided a reliable, non-surgical alternative for hyperhidrosis patients, setting the standard for future iontophoresis devices.

After Fischer's death in 1976, Anna Fischer continued his legacy, modernizing the company’s products with solid-state technology and introducing innovations like the industry’s first programmable muscle stimulator. The R.A. Fischer Company expanded globally, developing advanced medical devices for international markets. Today, over 60 years later, Fischer's vision and dedication to innovation remain central to the company’s mission, reflecting his enduring impact on the fields of electro-medical therapy and hyperhidrosis treatment.

Following Dr. Fischer’s pioneering work, iontophoresis technology evolved rapidly. Early devices were simple and often rudimentary by today’s standards, relying on basic electrical circuits to generate current. These early machines required significant manual control and monitoring to ensure patient safety, and treatments were generally conducted in clinical settings under medical supervision.

As technology advanced, iontophoresis devices became more user-friendly and accessible. The introduction of portable and home-use devices in the late 20th and early 21st centuries revolutionized treatment, making it possible for individuals to manage hyperhidrosis and other conditions from the comfort of their homes. Features such as adjustable current settings, automatic timers, and safety mechanisms were developed to improve the treatment experience and outcomes.

While hyperhidrosis remains one of the most common uses of iontophoresis, the technology has also proven valuable in other medical fields. The principle of iontophoresis for transdermal drug delivery is particularly important in physical therapy and sports medicine.

In the realm of physical therapy, iontophoresis is used to deliver anti-inflammatory and pain-relieving medications directly to the affected area. For example, it is often employed to administer drugs such as dexamethasone, a corticosteroid used to treat inflammation in soft tissue injuries. This method is preferred because it provides localized treatment, reducing the potential for systemic side effects associated with oral or injectable medications. The non-invasive nature of iontophoresis makes it an attractive alternative for patients who may be sensitive to needles or injections.

The process works by applying a medicated solution to the skin, followed by an electrical current. Positively charged drugs are pushed through the skin using a positive electrode, while negatively charged drugs use a negative electrode. The electrical current facilitates the penetration of the drug molecules into the tissues, making the treatment highly effective for targeted areas.

The significance of iontophoresis in modern medicine cannot be overstated. The treatment has provided relief to countless individuals suffering from hyperhidrosis, offering a simple yet effective solution that can be tailored to their specific needs. For physical therapy and sports medicine, iontophoresis remains a crucial tool for pain and inflammation management, especially for conditions that require localized drug delivery.

Iontophoresis has also opened the door to further innovations in transdermal therapies, influencing research into advanced drug delivery systems. The principles laid out by early pioneers like Dr. R.A. Fischer continue to inspire ongoing advancements in the field, and his name is synonymous with the transformative power of this technology.
