Case Study 4: Intra-nasal delivery      
         
 
Physica's Biodis technology was used to develop a formulation of Compound 4. The bioavailability of Compound 4 administered by nasal spray is much lower compared to subcutaneous injection (about 12 times lower). The goal of this project was to improve the bioavailability of the compound administered via intra-nasal route. .
