Problems solved by technology

It is suitable for the prevention and treatment of bronchospasm in patients with bronchial asthma, asthmatic bronchitis and emphysema, and relieves symptoms such as dyspnea caused by airway obstructive diseases such as bronchial asthma, chronic bronchitis and emphysema. Its advantage is that it works quickly , can quickly improve the patient's symptoms, relieve spasm, relieve asthma, and eliminate phlegm. Beta-agonist desensitization and even resistance to asthma therapy
[0006] Salbutamol sulfate and ambroxol hydrochloride are the active ingredients in the same minimum preparation unit. During long-term storage, due to possible chemical compatibility changes between the ingredients, by-products are likely to be produced, which will reduce the effect or increase side effects, and the product stability is not ideal.

Description

technical field [0001] The invention relates to the field of pharmaceutical preparations, in particular to an ambroxoxalbutamol solution and a preparation method thereof. Background technique [0002] Respiratory system disease is a common and frequently-occurring disease. The main lesions are in the trachea, bronchi, lungs, and chest cavity. Mild cases often cause coughing, chest pain, and respiratory problems. Severe cases have dyspnea, hypoxia, and even death due to respiratory failure. The death rate in the city is the third, while in the countryside it is the first. What should be paid more attention to is that due to air pollution, smoking, population aging and other factors, chronic obstructive pulmonary disease (referred to as COPD, including chronic bronchitis, emphysema, pulmonary heart disease), bronchial asthma, lung cancer, etc. , Pulmonary diffuse interstitial fibrosis, and the morbidity and mortality of diseases such as pulmonary infection are increasing. ...
