Autoimmune diseases occur as a result of the immune system attacking the body's own organs, tissues, and cells.1 Today, scientists know about more than 80 autoimmune diseases such as multiple sclerosis, lupus, inflammatory bowel disease, and rheumatoid arthritis. Many of these diseases require lifelong treatment to ease symptoms and reduce accompanying onset flares.2 There are no cures for autoimmune diseases yet, thus consistent, reliable, and accessible treatment is critical for managing patient's symptoms while minimizing the burden on patients' day-to-day lives.
Drug delivery systems play a critical role in managing autoimmune diseases. Pharmaceutical developers must take into consideration treatment delivery success as well as good usability.
