Efficient and reliable delivery of drugs to the colon has not been achieved so far, although urgently required for the treatment of inflammatory bowel disease, a malady with increasing incidence. The difficulty in consistent colonic delivery is caused by the individual and circumstantial variability of the human digestive tract (pH, residence time, water content, food intake, volume, peristaltic movement, etc.).
Scientists at a Swiss university of applied sciences have developed a novel technology for colonic drug delivery by per-oral administration.
