Chronic obstructive pulmonary disease （COPD），allergic asthma and bronchial asthma are major diseases to be prevented by the Healthy China 2030 Action Plan. In 2021，the Chinese Medical Association’s “Guidelines for the Diagnosis and Treatment of Chronic Obstructive Pulmonary Disease” show that there are nearly 100 million people with COPD in China over the age of 40. Documents such as the “Global Initiative for Asthma Prevention” and the “Global Initiative for the Diagnosis，Treatment and Prevention of Chronic Obstructive Pulmonary Diseases” recommend the use of inhalation preparations for treatment. This paper reviews the treatment strategies of asthma and COPD，market information，the definition and classification of inhalation preparations，the development of domestic inhalation preparations，and major companies’ R&D and applications. It also discusses the challenges and prospects facing the industrial development.
