Abstract
Description
technical field
[0001] The invention belongs to the field of drug synthesis, and in particular relates to a compound aminophylline nano-dispersant and a preparation method thereof. Background technique
[0002] Due to the deteriorating environmental quality, air pollution has become a major public hazard that endangers human life. Smoking and drug abuse are becoming more and more common. At the same time, various new viruses, bacteria, chlamydia and other pathogenic microorganisms are complicated. The incidence of respiratory diseases has greatly increased, seriously affecting the quality of life of the public. Aminophylline, as a commonly used drug for respiratory diseases, not only requires the standardization and standardization of clinical use, but also needs to be further developed and researched to improve its safety and curative effect, thereby contributing to the treatment of diseases.
[0003] Theophylline has been used to treat bronchial asthma for decades. Becaus...
