First Virtual Stomach Explores Drug Delivery

Researchers have developed the first virtual stomach, a computer-generated model that is providing unique insights into the way medicines are released from pills and capsules. “There’s no other technique to allow you to see flow patterns in a real stomach, animal or human,” said lead researcher James G. Brasseur, Ph.D., a professor of mechanical engineering and bioengineering at The Pennsylvania State University. Although pills and tablets have become a ubiquitous part of our society, the detail of how the stomach breaks them down to help release their medicine remains unclear. “You can give someone a drug and measure its uptake in tissue,” he said, “but the process between administering the drug and the uptake is largely guesswork.”
