1. The observed order of reaction of photodegradation of nitrofurazone solution depended on both the concentration of the drug and the illuminance of the incident light.

2. Objective: To study the effects of nitrofurazone and ephedrine nasal drops on mucociliary transport function in children.

3. Objective To explore the relationship between the illuminance and the observed order of reaction of photodegradation of nitrofurazone solution.

4. Conclusion The observed order of reaction of photodegradation of nitrofurazone solution depends on both the concentration of the drug and the illuminance of the incident light.

5. Therefore, doctors in the treatment of otitis media, often patients will prescribe nose drops, nose drops and other drugs such as nitrofurazone.
