What is the main purpose of iontophoresis?

The main purpose of iontophoresis is to introduce ions into body tissues. This technique involves the use of a small electric current to drive charged medication ions through the skin and into the underlying tissues. Iontophoresis is commonly utilized in the treatment of various conditions, such as inflammation, pain, and localized delivery of medications, like corticosteroids.

The effectiveness of iontophoresis lies in its ability to deliver therapeutic agents directly to the affected area, which often results in a faster and more targeted treatment compared to systemic medications that are absorbed throughout the body. By using electrical energy, the therapy enhances the permeability of the skin, ensuring that the medication can penetrate deeper into the tissues where it is needed most.

This treatment modality is distinct from options that suggest strengthening muscles or promoting relaxation, as its primary intention is the transdermal delivery of drugs. Similarly, while reducing inflammation can be a secondary effect of the medication used during iontophoresis, the core function is facilitating the entry of ions into tissues.
