Research suggests a new nanomedicine strategy for treatment of IBD patients

Inflammatory bowel disease (IBD), also known as "green cancer", is a chronic, non-specific disease of the intestine. IBD includes ulcerative colitis and Crohn's disease, both of which tend to be debilitating, lifelong conditions that can prove fatal in severe cases. Currently, there is no cure for IBD. The main clinical treatments are drugs such as aminosalicylic acid preparations and corticosteroids, but they are often accompanied by gastrointestinal problems, anemia, and various intestinal complications. Finding alternative, more effective options is a priority for researchers.
