Nasal sprays to kill pills, jabs

Scientists claim that they are working on a new project to design more effective nasal sprays to provide alternate drug delivery to needles or pills.

An international team, led by RMIT University, says it has already developed computer models which can explore deep into the human respiratory airway and also focus on particle inhalation, allowing scientists to understand how particles move through the nasal cavity and where they deposit.

Moreover, the models allow for powerful visualization and reproduction of these particle flows and deposits.
