(5)Jan-19-11 Using a magnetic gelatin capsule and a magnet, scientists can hold pills in a specific place in the body, pinpointing the most effective location for the body's absorption of the drug.
Some drugs can only be absorbed in specific parts of the intestine, and traditional oral pills don't usually stay in that one spot long enough to absorbed into the bloodstream. The new drug delivery system, developed by scientists at Brown University, uses an external magnet system with computer control and feedback mechanisms to monitor the amount of force on the magnetic capsule, holding it the ideal location for absorption while preventing it from being pulled toward the magnet.
The method has been tested in rats, with the magnet holding the pill in place for 12 hours without any damage to the intestinal wall.
