Problems solved by technology

In these administration methods, the residence time of the drug on the mucous membrane is short, and it is easy to lose to the throat, resulting in poor efficacy and inaccurate dosage of the drug, which affects the absorption of the drug by the nasal mucosa and affects the effect of the drug, especially analgesics or insulin. The administration method of cotton ball, the dosage is inaccurate, the mucous membrane can only absorb the drug on the surface of the cotton ball, and the drug that penetrates into the center of the cotton ball is difficult to absorb, and it will also be affected by nasal secretions
