Researchers at University of Southern Denmark have developed a new drug delivery system that can effectively transport the drugs to the right place in the brain.
The new technique involves taking the drugs by spraying them into the nose and the drugs then travel through the nasal wall to relevant areas.
The researchers identified a natural sugar polymer that can not only act as the perfect vehicle for delivering the drugs but also release them once they reach the right place.
Writing in the report that has been published in the International Journal of Pharmaceutics, the researchers said that the next challenge was to ensure that the drugs stick to the nasal wall long enough, rather than quickly sliding down and out of the nose. "We now need to invent some kind of glue that will help the solution stick to the nasal wall and not run down and out of the nose within minutes", the researchers wrote in their report.
