About Bi-directional Nasal Delivery Technology
OptiNose’s bidirectional nasal delivery technology significantly improves delivery to the targeted sites deep into the nose. While exhaling into the device, the soft palate automatically closes off the nasal cavity completely. The breath enters one nostril through a sealing nozzle and triggers the release of drug particles into the airflow. This action causes the narrow nasal passages to expand and carry these particles beyond the nasal valve to targeted sites. After delivering drug particles to the targeted sites, the air flow then exits the nasal cavity through the other nasal passage in the opposite direction.
