- the nasal powder formulation of the present invention when sprayed / inhaled into the nasal cavity, contains a powder of a non-water-absorbing and poorly water-soluble substance, whereby a physiologically active substance, a mucolytic agent, and a nonionic surfactant are added. It adheres to the nasal mucosa and stays there, and since the powder of a non-water-absorbing and poorly water-soluble substance does not absorb the mucus of the nasal mucosa, a physiologically active substance and a mucolytic agent The ionic surfactant dissolves in a small amount of mucus, and a physiologically active substance, a mucolytic agent and a nonionic surfactant produce a locally concentrated solution.
- the absorption of the nasal mucosa is locally improved by utilizing the concentration gradient of the physiologically active substance and by the action of the mucolytic agent and nonionic surfactant dissolved at a high concentration. Efficiently allows the physiologically active substance to reach the underlying vascular system from the nasal mucosa. The nasal absorption of the physiologically active substance can be promoted.
- the powder of the non-water-absorbing and poorly water-soluble substance does not inhale the drug dissolved in the nasal cavity by itself, the drug utilization does not decrease.
