systems for delivery of powdered drug formulations. ViaNase ID (Kurve
Technology, USA) (Figure 15) is a hand-held nasal delivery device operating
using a smart electronic technology that offers controlled particle dispersion
which is able to identify the right drug and expiray date by reading a code
located on drug ampoule or package. Accordingly the device decides the
optimal droplet size it will generate, the delivery rate and wether to operate on
breath-activated mode. The ViaNase also has a data storage and transmission
system to be downloaded by health care professionals upon need to track the
history of drug administration by patient. This device is superior to nasal
nebulizers and pump sprays in targeting the paranasal sinuses and saturating
the nasal cavity (Giroux, 2005; Giroux et al., 2005). Figure 16 shows a
comparision of nasal deposition between a model conventional nebulizer, a
spary pump and the ViaNase device using scintigraphy. The study clearly
shows higher nasal deposition and greater distribution of the delivered material
within the nasal cavity when the ViaNase system was employed (Figure 16)
(Giroux et al., 2005).
