Abstract
Description
Technical field:
[0001] The present invention relates to the drug tiotropium bromide olodaterol spray for treating respiratory diseases, especially asthma, chronic obstructive pneumonia, bronchitis etc. The surface tension of the Datro spray pharmaceutical composition makes the spray particle size, spray time and spray speed of the composition more suitable. Background technique:
[0002] Asthma is a chronic airway inflammation characterized by reversible airway obstruction and increased airway responsiveness. Airway obstruction is caused by two factors: increased secretions caused by bronchial mucosal inflammation, mucosal edema, and smooth muscle spasm stimulated by inflammation; while asthma Increased airway reactivity is also a result of damage to the bronchial epithelium due to airway inflammation. It is recognized that only by controlling the inflammation of the airway mucosa can the ultimate goal of reducing airway hyperresponsiveness and relieving asthma symptoms be...
