Scientists at Penn State have developed a virtual road map of the human stomach to better determine how a body absorbs pharmaceuticals. They found that a narrow path at the center of the stomach acts as an avenue for the more rapid processing of food. The researchers theorize that if pharmaceuticals are developed with higher densities, they can sit at the bottom of the stomach, allowing for longer periods for the drug to be released. Their study is on the online edition of the Journal of Biomechanics.
