A new approach to delivering drugs may allow morphine and other strong medications to be targeted directly to the central nervous system. Researchers at the University of Washington, who have developed and tested a pressurized olfactory device (POD) in mice, say a similar technique used in humans might provide an effective technique for the administration of opioid drugs. The result, they claim, would be improved pain control with fewer side effects and faster action. The POD is designed to deliver morphine with greater accuracy to the olfactory region of the nasal cavity, a tiny area between the nose and brain that is an attractive target for drugs targeting the central nervous system (CNS).
