Nasax – proprietary powder formulation for intranasal delivery comprised of uniform size spherical API and a carrier approved for inhalation.
Technology targets a rapid and precise delivery of the drug to blood stream and brain
Stability data demonstrated potential for longer shelf-life
Proprietary Nasax Platform Enables Superior Drug Absorption
Powder formulation can reach all parts of nasal cavity; The greater intranasal absorption area enables faster delivery and higher maximal drug concentration compared to liquid formulations
Liquid Epinephrine Formulation
Liquid Spray
Less surface adhesion
Pooling and runoff into nasopharynx
Variable droplet size
Slower, less predictable absorption
Powder Epinephrine Formulation
Dry Powder
Uniform nasal surface adhesion
Minimal runoff or drip
Uniform spherical size
Higher and faster absorption
